Yaesu FT-DX10

March 26th, 2023 |

Shiny new Rig -- Yaesu FT-DX10

I ordered my FT-DX10 from R&L Electronics this week, along with a 300Hz Yaesu Crystal filter from Ham Radio Outlet, because R&L didn't have the crystal filter in stock. This is my first order from R&L and I'm happy with their communication and slightly lower prices than the major equipment providers. They also included an R&L Electronics branded 30A 12v supply for only $40, and I always seem to need a separate power supply.

FT-DX10 next to the KX3

Initial Impressions

It has been over 12 years since I used a Japanese brand transceiver. Compared to the Elecraft KX3 and Ten-Tec Eagle the FT-DX10 has a higher level of fit and finish. The case, buttons and switches have a high grade feel.

I had previously not been able to physically see one of these radios and if I had I may have passed due to the way you physically interact with the radio. The button placement is decidely cramped. Even though the KX3 and Eagle have significantly smaller front pannels, they both have good spacing between their buttons and knobs compared to the FT-DX10. All the front panel space used by the FT-DX10's large display definitely reduces the space for physical controls.

I probably touch the AF/RF knob more than any part of the radio. It is small. It is slightly smaller even than the AF/RF knob on the compact KX3, and much smaller than the control knobs on the Eagle. It's proximity to the VFO has resulted in me accidently moving the VFO off-frequency multiple times. I would have preferred Yaesu have a smaller VFO knob to make more room for the physical control surface.

Related to the "cramped" controls, I find myself regularly locking the VFO on this radio. I've never needed to do that on another radio and it's a bit frustrating. I'm assuming I will become more familiar with the placement and reduce my incidental presses with practice.

In Use

Audio

The audio from the built-in speaker sounds okay on SSB but is very muddy on CW. I tried playing with some of the EQ controls but I think the large cabinet space under the speaker is just creating a bit of a CW echo chamber at the 450Hz frequency that I like to listen to code at. CW output at a higher frequency doesn't have the muddy problem but I've developed a painful sensitivity listening CW at higher frequency. I'm now using an old Vertex mobile speaker on top of the radio and that has cleaned up the CW audio.

Similarly, when using headphones I hear a lot of high frequency hiss even when the audio is turned completely down. It requires an in-line resistance (outboard volume) or use of higher impedance headphones to eliminate the hiss. I know a lot of older hams have lost much of their higher frequency hearing but I'm not there yet.

The "sound" of CW from the radio when gain levels are properly managed and the digital noise reduction is employed is quite nice. It is MUCH better than the audio of the Elecraft KX3 but still not quite as good as the audio from the Ten-Tec Eagle. The only thing I can say about it is that it sounds less musical than the Eagle. At some point I will hook up an audio scope to both and compare the audio waveforms. For now I don't mind listening to it but I haven't had the chance to spend hours listening.

Button mashing

I was concerned about how many times I would have to enter the menu during operation and so far I'm fairly pleased. There are physical buttons for most of the functions I want to perform during a QSO. I had considered buying the less expensive FT-710 rather than the DX10; but the MPVD (Multi-Purpose-VFO-Outer-Dial) on the DX10 provide a lot of value by having an additional control ring. By having both a function knob tied to one of a dozen different functions, as well as being able to assign a function to the MPVD I find that I don't often have to go into the menu.

Compared to my Ten-Tec Eagle it is easier to operate because the dual-use buttons on the Eagle are perpetually in the wrong mode for me. Compared to the Elecraft KX3 it is about on-par usability wise.

I wish it had a dedicated knob for power but I understand that I am likely in the minority of people who start nearly every QSO at QRP levels then raise power if needed. Speaking of QRP, 5 watts is as low as the RF power can be set. The Eagle will go down to one watt and the KX3 will go down to 1/10 watt.

I am still a little confused about the APF (Audio Peaking Filter) functionality. The button goes through 2 presses in CW mode and the second press seems to do something different but I'm unsure what that is. The manual doesn't mention a second press.

The APF is not as effective as the APF on the KX3 at pulling out a weak signal, but the KX3's APF is very strong and makes the signal sound weird. I don't normally leave it on. The FT-DX10 APF doesn't negatively impact the sound of the signal but doesn't pull it out as much either. Mabye there's something else in the menus I haven't seen yet.

Features

FT-DX10 DNR (Digital Noise Reduction / as opposed to 'Do Not Resuscitate') works very well on CW. It works much better than the NR (Noise Reduction) on the Eagle or KX3 for CW. You have to play with the different DNR levels on any particular QSO to find the right match, but once you do it works very well. I don't think it works as well on SSB as the NR on the Eagle, but blows away the NR on the KX3 on SSB.

The display, ah yes the display. The display is large and colorful. I tried using the 3DS (Three Dimension Waterfal) for about 30 minutes and while it is mesmerizing I don't find it as useful as the standard veritical waterfall. In particular, when there are static crashes the historical 3D waterfall image creates a tall "wall" that makes it very hard to see the signals before and after the static crash. Since we've had a lot of thunderstorms in the surrounding states (on Thursday evening one storm was producing 443 strikes a minute) it makes that 3D waterful useless.

The standard waterfall is quite useful although precisely selecting the signal with you finger is very hard, so the mouse needs to be used.

The internal tuner is matching all the bands on my 80m Windom including 30m which, according to my Elecraft W1 meter is 5:1. It shouldn't be able to perform a match on that since it's advertised as a 3:1 tuner yet it's working. YMMV.

The CLAR RX/TX (Clarifier) is what everyone else calls a RIT and it works very well. When pressed the MPVD ring makes adjustment quick and easy and it both lights up the button as well as has an indication in the display so you don't forget it is engaged.

The ZIN (Zero In) is essentially the same feature as the SPOT function on the KX3 and it works very well to automatically zero beat a CW station. I think it actually works better than the KX3's SPOT.

I haven't had need to work Split operation with it yet, but it has a button labled TXW which is a momentary button allowing you to listen to the transmit frequency which I think is nicer than having to swap the VFO's back and forth like I do on the Eagle. However, it's not quite as spiffy as the KX3 allowing you to hear VFO A in one ear of your headphones and VFO B in the other.

As far as standard memories, its operation is a bit disappointing. My Eagle and KX3 store both VFOA and VFOB frequencies when I save a memory, but the DX10 is only saving the VFOA frequency. On the other radios I like to quickly jump up to SSB by simply pressing the VFO A/B swap but here I have to store that as a different memory. That seems like an oversight, so I'm probably doing something wrong.

Nits

My biggest dislikes so far are related to how noisy it is in CW operation. The T/R (transmit/receive) relay is very noisy. Not in the same clacky league as the Heathkit HW-101 but still very noisy. In full QSK it sounds like an old school typewriter in the radio. My KX3 has silent PIN-Diode switching and the Eagle has a very quiet relay, nearly silent, so to hear the clacking doesn't put me in a happy place. I've sinced changed my normal full break-in use to semi-break in and lengthened the timeout to 500ms. I really, don't like that. I do very conversational CW and like to hear the other station wanting to break-in or hear if I've accidentally infringed on someone. I feel like I'm keying a repeater.

The other noisy thing is the fan. The fan comes on even when not transmitting and it's quite noisy. Compared to the Eagle which has internally baffled fans that you never hear and the KX3 has no fans at all; it creates a much noisier environment. I wish they'd placed the fan inside the chasis like the Eagle so that it wasn't so loud. I understand that again I'm in the minority. Most operators are used to nosiy relays and noisy fans or have an amplifier running that sounds like a Window Air Conditioner, but I'm used to a very quite operating environment.

Headphone use would mitigate both the noisy relay and fan noise but many times I'm just doing casual operating and listening through the external speaker.

It has an "external display" connector to go to an external monitor but the resolution is 800x640. That's like early 1990s monitor resolution. Anything bigger than a 15" external monitor results in a great deal of pixelization on the display. They could have upscaled the display to eliminate the pixelization which would make the external display looks less cheesy.

CW Decode works, sorta. The radio was advertised as supporting CW decode. The decoder covers up the waterfall and you have to exit decode to see the waterfall. I do use CW decode on the KX3 if I'm trying to get a DX station that is sending his call at over 30wpm, and the KX3 displays about 12 characters of information while leaving everything except the VFOB frequency visible. It's very useful on the KX3 and quite accurate. The decoder on the FT-DX10 shows paragraphs of decoded CW. I just want it for a quick assist, not to read 30 minutes of ragchew content from two ops. The other issue with the DX10 CW decode is that you have to set the CW speed in the menu to match the speed or the accuracy is really poor. Most decoders just figure it out. Even the ardruino decoder I built works better. I just wish it displayed a single line in the bottom of the screen.

While we're on CW, it has a CW "memory keyer" function but you have to display the menu and touch the screen to send a CW memory during the QSO. The memory keyer menu covers up most of the waterfall and going into any other menu function makes the "contest keyer" disappear. There is a FH-2 keypad that I believe operates without having the menu displayed. It's a very pricey $100 for a box with buttons connected to different resistance values, so I'll probably build one. For now I'm using my external memory keyer, which also allowed me to have my manual keys in series with the external keyer output so I can use both mechanical keys and my paddle at the same time.

My KX3 has two key inputs and so does the Eagle, so while I knew the DX10 didn't have two key inputs it is still something I'd miss if I didn't use an external keyer.

Lastly, this is a NIT for me but I can't find anything on the interwebs that says other people have this issue. I cannot get the radio to reliably interface with OmniRig. I use OmniRig to interface my radio with Log4OM and other software. I have searched and searched and others are not having this issue. I am using the most recent FTDX10.ini configuration file for OmniRig and have it configured with the same serial port settings that work with N1MM (38400, N, 8, 2, Handshake, Low). It is perplexing. OmniRig continuously loses connection to the radio. So this is likely some local PC / software problem I have that I shouldn't blame the radio for. I even performed a full reset to no avail.

Conclusion

This is the first new HF radio I've ever purchased. I've been licensed to use HF bands for about 16 years at this point, but I've only owned 6 other HF rigs in that time; all purchased used. I've owned a number of Yaesu VHF mobile and handheld radios but only one HF and that was the FT-857D. The FT-857 was a good, portable HF/VHF/UHF radio but due to the limited front panel space and very early DSP implementation was really on the struggle bus when used for HF.

For me this was a very expensive purchase. So expectations are high. I knew it was missing some features my other radios already had but I'd hoped the shiny display would make up for it. At this point it's a mixed bag. I do like the DNR very much and I can get clean sounding audio out of it using a external speaker, but that's about the only positive. The clacky T/R relay and noisy fan are a major Debbie Downer at this point.

I know that since I'm primarily a CW operator most of the issues are unique to CW. If I used Digital modes or did a lot of SSB I'd probably be thrilled with this radio. If I can figure out the rig interface problems I may try some digitial modes again and maybe it would seem more shiny. (I know I use the word "Shiny", a lot... It's because there was a Sci-Fi Series on a decade ago called Firefly. The chief engineer used that word for anything she thought was cool or nice... I have sort of adopted it)

I'll give it some more time and see how it works with weak signals. So far, I've only made a few dozen contacts and less than a dozen extended ragchews due to lots of lightning in my area. It's really a toss-up at this point as to whether the shiny stuff outweighs the musical audio, and slent operation of my Eagle.

That's all for now.

FT817 and FT817ND

August 21st, 2017 |

Author: Roger G3XBM

These little rigs from Yaesu have basically remained unchanged since 2000. They cover all bands from 160m-70cm (not 4m or 1.25m), all modes, 5W. With transverters, mine have been used from VLF upwards on all available bands. They work well, but I was surprised Yaesu did not do an upgrade in time for the last sunspot peak. Also, I was surprised they had no real competitors. These days there are a few SDR radios around, but the FT817 reigns supreme.

With mine I have worked the world including some great handheld DX. For base station use I recommend the Z817 auto-ATU.

I tried the Elecraft auto ATU but prefer the Z817. I am very happy with the FT817, although the early ones had PA failures with low voltage. This was fixed (I think) in the FT817ND.

System Fusion DR-2X Repeater, Solar Eclipse and More – ETH079

July 27th, 2017 |

Author: Curtis K5CLM

In this episode we talk about the Yaesu System Fusion DR-2X repeater, the upcoming Solar Eclipse and more.

There is some interesting new features on the DR-2X repeater over the DR-1X that came out a couple years ago, but there is also something that it doesn’t have. Some of these features, I wish that we had on our club repeater, but those features are not enough for us to go out and buy this version.

There are a lot of special event stations that are going to be on the air around August 21st this year when the full solar eclipse occurs. This is the first time since 1918 that a full solar eclipse has gone from one side of the US to the other. I unfortunately am to far south to the see the full eclipse, but I should get about a 75% one here in the DFW area.

We also talk about some other stuff, but you are going to have to check out the show notes and listen to the episode to find out what that is.

New ICOM and Yaesu products at Dayton?

May 18th, 2017 |

Author: Roger G3XBM

Dayton is often the place where ICOM and Yaesu announce new products. I’d like to see a replacement to the FT817 from Yaesu, but have all but given up hope. Certainly a few years ago they would have released at a time of sunspot peak. As it is, we have years of falling conditions, so not the best “window of opportunity.”

Review – BTech APRS-K2 Cable (TRRS/APRS)

November 14th, 2016 |

Author: Hans PD0AC

by John ‘Miklor’

APRS-K2
It’s long overdue, but there’s finally a TRRS/APRS cable available for radios using a standard Kenwood style K2 connector.

I’ve been wanting to get involved with APRS for a while now, and this made it extremely easy.

APRS-K2 interface cable
The APRS-K2 cable allows you to interface your handheld transceiver with your existing mobile device, including. iPhone, iPad, and Android.

One end of the cable uses the Kenwood style K2 connector, while the opposite end is terminated with a TRRS connector. Also included with the APRS-K2 is a Reverse Adapter to insure compatibility with all devices. This adapter allows cable to connect to earlier 3.5MM TRRS standards, such as Nokia.

App Driven
The APRS-K2 cable uses a virtual TNC found in several apps, such as APRSDroid, APRS.fi, and Pocket Packet. Plug in the cable, turn on the VOX, and you’re pretty much set to go.

Product Description
BTECH APRS-K2 TRRS / APRS Cable A simple way to start using APRS by using devices you already own. The BTECH APRS-K2 Cable will quickly connect your radio to APRS by using virtual TNC (app driven) on your tablet or device. The APRS-K2 cable is built with a custom circuit board that will automatically adjust the audio for clear packet transmissions with minimal adjustment; along with protecting your devices from strong over modulated signals.

Along with allowing APRS functionality the APRS-K2 cable can provide a simple interface gateway to allow several features to your radio!

Easily record radio conversations:
By connecting the APRS-K2 cable between your radio and any recording (line-in) device.

Use the APRS-K2 cable as a Mic In Connector:
Set up VOX on your radio to accept any form of incoming audio – such as a Push-to-talk application on a Phone – or a Line-out application from your computer.

Use the APRS-K2 cable to push transmissions over a speaker system:
Easily play audio over a intercom or speaker system from your handheld.

With a backup radio and your own ingenuity, the APRS-K2 cable can serve as an interface for a variety of applications for any amateur.

The Baofeng Experience

August 6th, 2016 |

Author: Jerry KDØBIK

Last week I cleared the dust out of my blog and podcast websites and briefly discussed ordering the Baofeng UV5RA HT from Amazon. While this model was released several years ago, Amazon has them available brand new for $26.06. This includes the HT, charging stand and hands-free kit. Here’s the link to the Amazon product page for the Baofeng UV5RA HT.

I guess it’s been several years now since these cheaper (I guess less expensive might be the more PC way of describing these) Chinese made hand-held radios came onto the market here in the US. Fellow hams began showing these off at local club meetings and I began reading reviews of these radios on various amateur radio blog sites from around the world.

For the most part, the opinions expressed all seemed to have a common theme around pricing, ease of use and durability/reliability. Many viewed the low cost of ownership to be favorable over any durability issues. I guess the idea of use it, abuse it and toss it comes to mind. I also seem to remember a strong sentiment of “steer clear” when discussing these units.

I could see all sides of the argument. But I also fully understand some folks just getting into the hobby may be on a limited budget and may not have the resources to afford the latest and greatest from ICOM, Kenwood or Yaesu. As time went by, I really didn’t hear complaints regarding the durability/reliability of the radios. But certainly most everyone I spoke to all said that the programming of the radio was often a challenge and the provided user manual was of little to no help.

As for me and my reasons for not entertaining the idea of these cheaper Chinese made radios all boiled down to the fact that I really didn’t need another HT. I already own more HT’s than I have hands, so I just didn’t see the need.

So what changed?

Last week I was thinking about future topics to discuss on the Practical Amateur Radio Podcast and was researching just how many different HT models were available and the price range. This research led me to all the usual amateur radio dealers as well as a quick check of Amazon. I simply searched for Baofeng and that’s when the UV5RA popped up. With my Amazon Prime membership and a $3.00 credit, I could actually get this HT home for less than $25.00. Deal!

I decided I would gain some first hand experience with at least one of these cheaper Chinese made HT’s and share my knowledge with all of you reading this blog and later on the podcast.

Reverse Bait and Switch???

So my package shipped from Amazon as expected and was delivered on Saturday. I opened the package and inspected the contents. Immediately I noticed something was different.

If you look at the Amazon product page for the Baofeng UV5RA you’ll see the photo below. This is the Baofeng UV5RA. However, the HT shipped to me looked nothing like this.

Instead of receiving the UV5RA (as shown above), I received the UV-82 (shown below).

Initially I was slightly upset. We’ve ordered a lot of items from Amazon. While this was my first amateur radio purchase, it was also the first time I didn’t receive exactly what I believed I ordered. However, after doing a little more research I discovered the following:

First, while the Amazon store page for the Baofeng UV5RA doesn’t match what I actually received. If you carefully read the product description, under the section “What’s in the Box?” you’ll see the Baofeng UV-82 listed.

Second, from what I understand…the UV-82 is an upgraded (newer) Baofeng hand-held. If I read this Baofeng product comparison chart correctly, the UV-82 includes an updated PCB, commercial grade case and other enhancements as compared to the UV-5R models.

Third, the UV-5RA is a 4 watt model with the UV-82 offering 5 watts output.

Did I get what I paid for? Well…not really….but advantage appears to be all mine. I can’t guarantee what will happen if you order the same model I ordered…but from all appearances you’ll also receive the UV-82. Just no guarantees. Alternatively, you can purchase the UV-82 via Amazon (listed as UV-82) for $28.80. It’s a few dollars more than what is listed on the UV5RA product page, but you’ll be guaranteed to receive the UV-82 if that is the model you desire.

How I plan to use the new radio

Before I go into my initial thoughts/review/feedback (what ever you want to call it), I think I should clarify exactly how I plan to use this new Baofeng UV-82 transceiver.

This radio is not replacing anything I currently own. My main go-to HT is the Yaesu VX-8 which I have the GPS module installed. I also own an older Yaesu VX-6 (which I should probably sell) and also the ICOM IC-92 D-STAR HT which I also rarely use.

I actually plan to program a few local repeaters, simplex and NOAA weather frequencies into the Baofeng and leave it at my office. For less than $25.00 I am really just considering this a weather radio that will do a little bit more.

Initial Thoughts

I’ve had the UV-82 now a few days and feel comfortable in sharing some of my initial thoughts on just what I think of this radio. I’ll break my thoughts down under a few different categories.

Over all Design

The overall design of the radio (my opinion) is fine. The radio fits nicely in my hand (not too small, not too big). It sort of reminds me of an older Nokia cell phone from the time when cell phones weren’t smart.

Channel Mode/Frequency Mode

If I’m honest, I really dislike having to power the radio off to switch from channel mode back to frequency mode. While it’s simple enough, just hold down the Menu button while you switch on the radio. All my other HT’s have a button which toggles between the two modes. However, as previously stated…this radio will be programmed with a few local repeaters, simplex and NOAA weather frequencies. For the most part, the radio will be used to listen to weather information from the national weather service.

Case Quality

While I’ve not taken a hammer to the case (nor do I plan to) and I’ve not performed a drop comparison from the top of my building (I don’t plan to do that either). The overall case quality appears to match that of my Yaesu rigs. As I’ve previously stated, the radio fits nicely in my hand. It’s easy to grip and the included belt clip has a nice firm spring. While I don’t plan to use this HT as I use my Yaesu, I also wouldn’t have an issue clipping this onto my belt or pack and heading down the trail.

Stock Rubber Duck Antenna

What’s In Your Rubber Duck? Well this was answered by Bob, KØNR and I would highly recommend reading his excellent review where he reveals the “inner workings” of several popular stock rubber duck antennas (including the Baofeng UV-5R).

But what can really be said about ANY stock rubber duck antenna? Regardless if the radio brand is Yaesu, ICOM or Baofeng, you will greatly improve the radio by installing an aftermarket antenna. I use the Diamond SRH77CA on my Yaesu VX-8 and it works great. But at the moment, I have no plans to replace or upgrade the Baofeng rubber duck.

Screen

The LCD screen on the UV-82 is slightly smaller than what I’m used to on the Yaesu VX-8. But to be honest, if I don’t have my reading glasses with me 24×7 these days…and the screen size doesn’t rival the Dallas Cowboys Jumbotron, I’m not able to see anything.

Dual PTT functionality

The UV-82 features dual PTT switch functionality. This is a bit odd (compared to my other HT’s). I suppose in time I will get used to it.

FM Broadcast Band

If this is something you care about, the UV-82 features a button on the side which switches the radio to the FM Broadcast band.

Built in Flashlight

If you are in the need of a hand-held amateur radio transceiver WITH a built-in flashlight, then the UV-82 is the rig for you. A conveniently placed button on the side will turn on/off the flashlight.

User manual

This is the radios weakest link and is perhaps not worth the paper they used to print it. It could be written in Chinese and even non-Chinese speakers would obtain as much knowledge by reading it.

But seriously, the entire user manual is 29 pages long. Not one page actually covers how to program the radio. Thankfully YouTube exists and many others before me figured it all out and shared their knowledge.

Ease of Programming

The UV-82 offers 182 different channels which can be programmed (once you figure out how to program them). Unfortunately, Baofeng (in their infinite wisdom) pre-programmed 20 channels (1-21). As you can’t edit a pre-programmed channel, you’ll need to delete these which can be done one-by-one in the menu.

While I believe it might be a daunting task for any brand new ham (or soon-to-be brand new ham) to sit down with an HT, User Manual and Repeater Directory and successfully program the radio. The Baofeng (unfortunately) really makes it impossible. This is part of what I was talking about during the Practical Amateur Radio Podcast (episode 70). As I’ve always recommended the Nifty Ham Radio Guides for ALL radios, I think it is a must have for the Baofeng.

Alternatively, if the UV-82 is going to be your primary hand-held and you’ll want/need to reprogram often. I would highly recommend purchasing the programming software and cable from RT Systems. While I don’t plan to purchase the the cable/software for the Baofeng, I do own the software and cables for all my other rigs.

In Summary

While I’ve not discussed each and every feature/benefit of the Baofeng UV-82 in this blog article. I’ve identified a few key areas which I’ve discovered and most importantly have feedback/opinions on regarding. More importantly, as I’ve previously mentioned…I don’t plan to heavily use this radio. But having said that, I also wouldn’t have an issue with clipping it to my belt and heading down the trail either.

The opinions within our hobby of what makes a great first radio for a beginning ham are strong. Some are pro the HT and some are against the HT. If you are just starting out in our wonderful hobby, on a tight budget and looking to pickup a radio which won’t break the budget and allow you to enjoy the hobby…then I certainly recommend the Baofeng UV-82. After all, the package contains everything (transceiver, antenna and power source) you’ll need to get on the air. Get your ham radio license and join the fun of the worlds best hobby.

Until next time…
