Three band HT Radio, 2 Meters, 70 CM and 6 Meters

“I hate this radio”

Have you ever said this?

I certainly have. Some radios are a joy to use. They are intuitive, easy to use and you don’t ‘NEED THE MANUAL’ every time you want to change something!

HT’s seem to be the most ‘user hostile’ radios available to hams. I know! All HT radios should have certain things, VFO, on off knob/button, volume control and keypad, and in my opinion, they should not be so difficult to use that you need to read the manual every time you want to do, what should be a simple task; change CTCSS tone of a repeater, for example!

When HT’s were reduced in size, they became more complicated to use. Menu systems were instituted. They were further reduced in size and menus were multi-layered! How many times have I yelled at my HT after holding button a for 1 second, then within 4 seconds, tried to press button 2, for 1 second but no more than 2.5 seconds, while doing 3 pirouette turns on my left foot, only then, can I use my radio. That same button has 3 functions now a days. Press it once for one thing, press it again within a specified number of seconds and you get another function. Press and hold it and you get yet another option.

Enter the English Translation, manual! Poorly translated from Japanese, but at least its in English!  (With many pertinent things omitted!)

Why do manuals go to great lengths to tell you in great detail everything that you ‘don’t want to know’ and will most likely never use or use very seldom?

But tell you want you NEED TO KNOW, naw!  Tell you how to ‘undo’ something? That would make it too easy!

Actually, I really like this VX5-R HT from Yaesu. It’s a love/hate relationship, however! So very handy, it fits in the palm of my hand, has lots of memories, and many many nice features. Accessing those features is not always easy, especially without the manual right in front of you. If you ever push the wrong button, and send it into ‘never-never-land’, its hard to un-do what you just did! One thing that was left out of the VX 5 is a memory clear feature!  That omission makes life with this radio difficult at best!

You cannot return a designated memory channel to its ‘no data’ state. The only thing you can do from the radio itself is to overwrite that particular memory with another frequency!

2 Meter IC V8000

I’m not picking only on Yaesu!

This Icom V 8000 is the most ‘User Hostile’ radio that I have ever owned.

Not only is it difficult to use, but it has problems as well. The mic is notorious for a mechanical problem with the PTT button, and the external speaker jack does not work well. Unfortunately, the external speaker jack is where you have to plug the programming cable in to program the radio. The Icom program for doing this is also ‘user hostile’ BTW!

Editing and Cloning Software RT Systems I bought software and cable from RT systems to program and manage the Icom T 70-A. The HT and its programming software arrived yesterday.

 The Icom T-70-A, is the replacement radio for the Yaesu VX 5

It will replace the VX5 as my ‘go to’ HT. Just last night, I picked up the Yaesu VX5 the wrong way, mashed some buttons on its face and sent it into never-never-land!  Try as I may, I could not undo it with normal button press. Since the radio has an RT Systems program and cable on its way, I went nuclear, and reset the processor. Finally, the radio was operational once more. It needs programming of course but the display is no longer stuck!

It programmed the Icom T 70-A radio to my specifications with only a cursory reading of the manual. The radio is intuitive, easy to use and has some great features. RT Systems Programming Software and Cable

IC 7100 with Touch Paddles

Funny, I just installed an Icom 7100 mobile HF/VHF/UHF/MF radio in my truck. That radio was ‘done right’ by the manufacturer! Its easy to program and use, so there is no need to keep the manual handy for simple tasks. I run mobile CW/SSB and VHF repeaters with it. If there were any UHF in the area, I’d have that programmed in there too. Its a joy to use!

This photo shows the IC 7100 on a modified clip board held in place with bungee cords. So far, I have not seen the need for programming software. That said, there is an SD card on board this radio. It can save the settings to the SD card. I have not explored this avenue yet. It would be nice to keep a copy of the settings on an SD card and on my laptop for future use. Something unexpected can happen. Spare radio data would come in very handy then. Replacing all the settings would be very easy with the programming/clone software. RT systems sells that one too.

Do you have a radio that you love to hate? 

Special event, “K3Y,” the Straight Key Century Club’s annual January celebration, commemorates the Straight Key Century Club’s founding in 2006 following the American Radio Relay League’s “Straight Key Night” (SKN). A small group of participants wanted to extend the fun of SKN throughout the year. The Straight Key Century Club (SKCC) is the result.

For the first three years, the club’s founders used the special event callsigns of K1Y, K2A, and K3Y as the celebration’s special-event calls. But, someone cleverly noticed that a ‘3’ is nothing more than a backwards, curvaceous ‘E’. This “KEY” event has operated under the special event callsign of ‘K3Y’, ever since.

The on-air party is open to members and non-members alike. It runs from 0000 UTC Jan. 2 through 2359 UTC Jan. 31. It’s a great time to introduce others to the joys of hand-crafted Morse code using straight keys, bugs, and side swipers.

In this video, you can “sit in” with NW7US, the control operator of the regional activation of special event station, “K3Y/0”, during one of the many shifts during January (2015).

While many are talking about how Solar Cycle 24 is the weakest since the Maunder Minimum (the period starting in about 1645 and continuing to about 1715 when sunspots became exceedingly rare, as noted by solar observers of the time — see this Wiki entry), there are moments when activity on the Sun strongly increases, providing brief moments of excitement.

Here is a case in point, witnessed by the Solar Dynamics Observatory (SDO; see SDO Mission) on June 7, 2011, when the Sun unleashed a magnitude M2 (a medium-sized) solar flare with a spectacular coronal mass ejection (CME). The large cloud of particles mushroomed up and fell back down looking as if it covered an area almost half the solar surface.

SDO observed the flare’s peak at 1:41 AM ET. SDO recorded these images in extreme ultraviolet light that show a very large eruption of cool gas. It is somewhat unique because at many places in the eruption there seems to be even cooler material — at temperatures less than 80,000 K.

This video uses the full-resolution 4096 x 4096 pixel images at a one minute time cadence to provide the highest quality, finest detail version possible.  The color is artificial, as the actual images are capturing Extreme Ultraviolet light.

It is interesting to compare the event in different wavelengths because they each see different temperatures of plasma.

“Radio Hams” do more than play with their machines. They are also invaluable in relaying vital information during times of tragedy and disaster.

Here is a mildly entertaining look at radio hams, those amateurs sending and receiving coded messages during the late thirties when films first dealt with the subject of “radio hams.” In this case, the ham operators manage to be helpful during situations of stress, using their abilities with code to help someone in distress and to seek aid for pilots flying a missing plane.

The humorous ending has the family gathered around the radio listening to someone speaking Chinese while the narrator tells us how impressed the family was to be hearing someone across the world on their radio set.

This little vintage film, a rather more serious film than many of Pete Smith’s other presentations, takes a look at how ham radios can become priceless aids during emergencies. The two stories shown, one dealing with sickness, the other with a missing plane, are bookended by a humorous look at a typical three-generation family’s fascination with their ham radio.

Of course, amateur radio, or “ham radio”, is alive and doing very well, in our modern times. Using satellites, moon-bounce communications, repeater networks, as well as shortwave, mediumwave, and longwave telecommunications technology, amateur radio continues to provide emergency services in times of need, from hurricanes, tornadoes, earthquakes, and even during such times as the infamous 9/11 atrocity. But, amateur radio also breeds invention and experimentation, always at the cutting edge of science. It is a hobby worth investigating, having room for a wide-range of interests. Preppers, science lovers, experimenters, and those with a passion to meet people from all over the world by way of radio waves, all together make up the radio hobby of amateur radio.

The Sun currently is active, with powerful, complex magnetic structures that have formed a healthy number of sunspots. We are seeing a fair number of x-ray flares, which push the 10.7-cm flux higher than we’ve seen in a while.

Sunspots and flares means better propagation in general, especially on the higher frequencies of the shortwave spectrum.  While a flare can cause a short period of “blackout” conditions (especially on the lower frequencies) on the sunlit side of the Earth, such activity is part of the positive activity that ionizes the F-region, providing for DX.

Here’s a movie of one such flare and the release of solar plasma, a release known as a coronal mass ejection (CME): At about midnight, UTC, on 6 November 2013, a moderately-strong M-class flare erupted, with a “beautiful” CME: http://g.nw7us.us/18a0QvI

We will see continued flare activity over the weekend, so expect great conditions on the HF bands, with momentary blackouts.  Keep up to the minute on space weather at http://SunSpotWatch.com

Splinter Transceiver from BreadboardRadio.com

Kit building appears to be on the rise again.  With so many people talking about it lately I attempted to research sources for kits, only to find out that there wasn’t a single-source for Ham Radio kit suppliers.

I decided to put together a good list of sources for kits that are currently available.  Many of these are for QRP operation, but a few are full-featured professional transceivers (Elecraft, DZ).  On the beginners side there are a few sources that stand out:  Hendricks has a great assortment of kits, including some SSB QRP equipment.  QRPme offers the inexpensive, easy-to-build tuna-can products, and I would like to make special mention of the Four State QRP Group NS-40 which has the coils etched right into the PC board!  What a great idea!  I’ve covered trasmitters, transceivers, and some receivers here.  Some accessories are mentioned in the source descriptions.

Revised 2/18/2013  Changes in Hendricks, YouKits, Tony Parks. Added CR KITS, and BreadBoard Radio.

Revised 2/20/2013 Added K5BCQ & K5JHF Kits

Revised 2/26/2013 Added Kit Radio Company, GQRP Club, Kenneke Comm., Walford Electronics, Kanga UK, QRP Project, Kits by EA3GCY, and OZ QRP
