Icom DSTAR – 50 States in 50 Days Project

Let me start with saying that I love having goals and challenging myself in different ways… I came up with a challenge that I didn’t think would be too hard to meet but would be fun and stretch my operating time a little more than I have been on the air in a while. I love DStar and the fact that I live in an Antenna Restricted area makes me try to be more creative than ever on keeping my radio skills high as well as having some fun doing it. 50 States WAS is always one of the first challenges people go after when getting on HF so I thought why not try to do 50 States on DStar and to make it interesting come up with a catchy way to say it so there grew: 50 States in 50 Days. Sounds catchy right? I thought so…

Honestly, it should be a very easy goal to attain from a technology standpoint I mean get on a Reflector and you could pick off 5-6 states on a major reflector in on setting. Also, just linking to 50 repeaters should only take you what a day or two to do if you just rush through it…. Here is what do you haven’t added… Full time job, wife, two kids with full schedules, 4 dogs, 15 other hobbies and the fact that I’m pretty tired at the end of my day!! I have thought about doing this project for a while but I jumped in with both feet tonight with some free time I had tonight….

With that said… Let’s get started!!

March 30 –

  • Linked to KI4WXS in the Charlotte area to talk to my friend John – KJ4KJM who I got into the hobby and we had a quick QSO on his way home from work.
  • Linked to AA1HD in Vernon Connecticut because I was on a roll at this point and reconnected to one of my oldest (no age but long term) friends in the hobby Fran (W1FJM)
  • Linked to AC7O in UT and I got a change to meet Bob – KF7LQS who just got a 91ad and was learning his way around DStar from Logan, UT. Really nice guy and someone you should connect with if your online
  • Linked to K3PDR in Philadelphia, PA as my wife happened to be in that area and I LOVE THE FOOD there. After a few calls… K3DS Dennis came back to me while he was putting some finishing touches on his Shack.

Since we have some thunderstorms coming through and tornado warnings in effect I decided to shut down and take the rest of the night off. I’ll be back to my quest tomorrow hopefully…

Icom launches a new handy

Icom ID-51

Icom has demonstrated a prototype of its latest dual-band handheld transceiver – the ID-51A. (The European version will be the ID-51E.)

Covering 2m and 70cm, the ID-51 can also receive FM broadcasts and AM short wave radio. It supports D-Star (of course) as well as FM mode, and boasts a large 128×104 pixels display, the largest yet seen on an amateur radio handheld rig.

Like its smaller sibling the UHF-only ID-31, the ID-51A/E has a built-in GPS which can be used for track logging to a micro-SD card. The storage card can also be used to record incoming and outgoing voice traffic. Very useful – not!

Disappointingly though not unexpectedly, this new Icom does not support APRS, though it presumably supports D-Star’s rather lame version, D-PRS.

The ID-51 is being billed as the most technically advanced handheld, though it looks like you will be paying a lot for features – like the GPS and short wave receiver – for which most hams will have little use. I doubt that the large display – never mind the GPS – will do much to extend battery life, though Icom will offer an extended battery pack (at the usual inflated Icom prices no doubt.) However it is nice to see a manufacturer breaking the mould for HT user interfaces which have changed little for the last 20 years.

Solar Power for QRP

I’ve always wanted to operate my radio on Solar Power. This was a fun to do project. I can’t wait to bring it to a Field Day Event.

I bought the aluminum from Metals Depot in Kentucky. (link attached)  They have lots of aluminum shapes and parts to choose from. The parts arrived via UPS. It nice to have a good source like this for ham radio projects.http://www.metalsdepot.com/

 

HQRP is a good company to buy solar panel parts and controlers from. The QRP part of their name is just coincidental to this being a QRP project.  http://hqrp.com/

Icom IC-E92D – Why This Is My ‘Staple’ Handheld

Every ham has a handheld in their collection of transceivers. I have one normal rig in my collection of handhelds. Nearly all the equipment I have can be held in my hand, chucked in the car, operated ‘portable’ or temporarily connected at home. It’s the capability that would suit a cold war double agent who has to move between a series of safe-houses at short notice. Everything I have, I can pick up and run with. Just as well I don’t have an HF vertical that looks like a porcupine then.

I’ve had my beloved Icom IC-E92D for a couple of years now and I spend more time talking though this than any other piece of equipment. Two years ago there was no DV (Digital Voice) or D-STAR activity in my area, but I wanted a dual band handheld that would be, to some extent, future-proof.

And before the rival Yaesu C4FM digital system is mooted, let me say that D-STAR is so firmly established, that a lot of infrastructure would be needed to better the existing system. Great advances have been made lately with the advent of the German DV-RPTR (‘DV Repeater’) boards as well as the new DCS reflectors. Having said that, I’m always keen to try any new digital modes. 

I’m not going to dwell heavily on specification and features because this is not a newly launched product – there are plenty of excellent resources and reviews already available. But here are some things that have pleased me about both the radio and the technology behind it.

Icom IC-E92D
Let’s put the digital stuff to one side for the time being. I think the E92D is just an excellent FM transceiver in its own right. Its construction is solid and feels good in the hand. Used outdoors, it’s comforting to know that it’s waterproof. I live in Wales, after all. The send/receive audio quality is very good in all modes and the microphone doesn’t suffer from the aforementioned weather-proofing that blights some other units. It seems XYL’s sewing kits have been raided worldwide for needles to pierce microphone membranes.

I love using low power when I can. In DV mode you either get a R5 copy or rapidly nothing. Why not see how low you can go? The E92D will go down to 100mW and oddly enough I use this more than any other power setting. It’s also all you need for your home D-STAR hotspot, isn’t it? A group of three of us had a 2m net with a distance of 20 miles between the furthest stations. We all used DV mode and 100mW (external antennas, of course) for a full lock and quality audio output. Compare this with the FM mindset of achieving ‘full quietening’ in many local nets. Admit it - a small swell of pride is taken in how many dB’s ‘over’ are registered. With DV it is how few. Back to the E92D: If things get marginal and stressed then the next increments are 500mW, 1W and 2.5W. Unleash the whole 5W if it’s a national holiday or you’re feeling reckless. In common with many handheld owners, I also have an aftermarket antenna to add a little more gain when needed.

Built for the outdoor life - with HM-175
GPS Speaker-Mic 
I have, and recommend, the RS232C remote cable and bundled programming software. There are enough people now who have kindly uploaded their files (called .icf files) to the internet with repeater and node settings for entire countries. You can enter or edit data manually from the front panel, but as with most radios a computer will save you time you can otherwise spend chatting idly. Seeing how the channels and banks are organised on-screen helps you properly exploit the memory capacity. Apart from the usual, I have also stored AMSAT, marine band, PMR and SWL channels. I travel a lot so it’s good to have repeaters stored by region too.

Dislikes? Only a couple and they’re not going to jaundice my high regard for this pleasure-giving, grown-up gadget. Most E92D owners acknowledge that although the battery life is good, there is little warning given before the battery dies. A bit like a pet hamster. Again, with four power settings you should optimise your battery life. Secondly, I don’t think many consumers would eagerly vote for an SMA antenna connector over a BNC, but we have to live with that. The main problem can be a snapped pin from an over-stressed SMA to SO239 adaptor, for example. This happens easily, frequently and on one occasion to me. I sent my unit back to Icom UK for repair, as the stuck pin could not be extracted. I must add that their support and service was fantastic. The repair was carried out quickly and was not costly. Chastened, I made a pigtail adaptor for use in the car, shown below.

SMA - SO239 adaptor
As far as accessories go, I have the HM-175 GPS speaker microphone. The embedded data channel in DV is something we’re only just starting to fully explore. GPS position and distance reporting between simplex users or posts on APRS.fi via a repeater are fun. I also have a two-pin mic/headset adaptor for mobile work.

Just download an electronic manual and have a look at the level of specification and configurability! You'll find a new feature every day for the first few months. There are now the lower-cost IC-E80D and 70cm-only IC-ID31E to supplement the range, of course.

So, after two years I think the big test for any bit of equipment would be “If it was damaged/stolen/confiscated by vexed YL/XYL, what would I replace it with?” For me, an exact replacement, no less. It’s a much of a staple as the King Edward potato.

LHS Episode #052: Amateur Fantasies

Hello, podcast listeners! It has been an extra week that you've had to wait for our landmark episode 50 to be released. I (Russ)  had planned to do an episode from his hotel room in San Jose. Unfortunately, the network there was so bad it was impossible to record so everything was pushed back.

In this episode, we talk about life, love and amateur radio. OK, not really. But we touch on a number of interesting topics including the necessity of logging in amateur radio, theoretical nonsense like Internet via Moonbounce and, thanks to a couple of missives from AD7MI, we wax philosophical on our ideal ham shacks--computers running Linux included of course.

Thank you for being a listener of our show. If you're new: Welcome! Please tell everyone you know where they can find us. And keep fighting the good fight.

LHS Episode #033: Bill and Ted’s Excellent Episode

Episode #031 of Linux in the HAM Shack is now available, and nearly on time. Due to myriad circumstances in our lives, we had to put off recording of this episode until February 9th. It is therefore almost astonishing that I can announced that it is being released on February 10th. After this, everything should return to its normal bi-weekly cycle.

I would very much like to thank Bill, KA9WKA, Ted, WA0EIR and Andy (Integgroll on IRC) for filling in as co-hosts for Richard on this episode. Sadly I must report that Richard lost his mother to a battle with cancer yesterday morning. I know the thoughts, prayers and deepest sympathies of myself and our listeners are with Richard and his family during this time. Unfortunately, I do not have any further details on events in Balch Springs at this time. If you would like to send your condolences, please address them to [email protected]. Richard may feel like joining me to record again in a week's time, but if his circumstances do not permit, we will certainly carry on and offer him all of the time and space he may need to recover.

In this episode, our esteemed round table guests touch on a variety of topics. In usual fashion, I address feedback at the start. Beyond that, topics range from MicroHam digital rig interfaces, a rant about Yaesu, Linux Mint 8, cloud storage, e-readers and much, much more. Thank you for your faithful listenership.
