Dad’s Sony (re-post for Father’s Day)
My father was not a technical guy. He knew numbers. In the early days of our family business, my mother kept the books, and answered the phone at the house, while dad revolutionized the dental products business in the northeast. My brother Paul ran the stockroom, and I would help, usually reluctantly in the beginning, with some of the basic tasks that a nine-year-old could handle. My oldest brother Lee joined later, and became, and still is, one of the best Dental Equipment specialists in the business. You see, dad took his skills as a supermarket manager, and combined it with the business model of SnapOn Tools, and created MoDent, and for more than 15 years, made the competition wonder how he pulled it off. Dad passed away in California in 2009, and in his honor today, I would like to re-post something radio-related from my own blog I wrote about him. Happy Father’s Day dad!
(Dad’s Sony was originally published here at my blog Fofio! in April of 2011)
My father grew up in the ‘Radio Era’ which made him more radio-aware than my children are now. He
was by no means a hobbyist, but knew enough to tell good from bad. He knew that AM radios had to be turned for best reception, and a good swiveling whip antenna was necessary for FM reception. For him, the radio needed to be able to pick up his NPR stations, WCBS-AM, and get the Mets games when he was on the road.
I ran a sales territory for our family business. As Dad got older, he eventually came off the road, and ran the company from inside. Every now and then though, he would schedule to ride with one of his salespeople to keep an eye on things. He rode with me for few days once on my Northern New Jersey run. Thursdays on that run, I would sometimes stop at the offices of Gilfer Shortwave, and chat with the Jeanne Ferrell & Paul Lannuier. I had purchased several radios there over the years, and would buy the various shortwave books and guides from them as they were released.
That one Thursday that Dad came along, he got a kick out of Gilfer, and all of the radios. He and Paul talked for a bit, and he purchased a Sony ICF-SW20. Partly because he really liked the quality of the little radio, and partly because I think he liked the folks at Gilfer as much as I did.
Dad had this radio from then, till he passed away in December 2009. It was his main radio. I saw it on his nightstand, in the bathroom, and on trips back east to visit us. Even with all of the selling and swapping I’ve done lately with my radio collection, I will never get rid of this radio. To me it was an acknowledgment from dad that my interests in radio were appreciated, and is a memory of the man I miss. It currently lives on my desk at work, sometimes called to duty for news, and music. Thanks for the radio Dad! I’ll pass it down the line someday to Alec.
The Sony is still on my desk at work. Another note here: Dad always wanted me to get my ham license, and even bought me the equipment when I was a kid to encourage me. I wish he was around to see how much I enjoy this hobby, and how it has helped me find some of the best people I have ever met. 73 dad!
To cross, or not to cross?
I’ve seen several times in various forums, when people ask about setting up cross-band repeaters, some Hams mention that they cannot think of a use for that feature. Here is your example.
With a second car coming sometime in the next few weeks, the YL and I have been keeping our eyes open for a second dual-band mobile. We had 2 vehicles up until about a month ago, when my old minivan got to the point where my investment in repairs exceeded my nostalgic affection for it. I had a chance to get rid of it quickly when my mechanic said he had someone interested in taking it, as-is, for more than scrap value (steel is high out here, so don’t laugh).
I have a Radio Shack HTX-242. My first mobile rig. A great eBay find last year, but it was not holding up to everyday use. It’s also a little numb in the receiving department, so it’s currently sitting on my elmer’s workbench. The goal there is to get it receiving well enough to use a my doppler receiver. The main radio is an Icom IC-207H dual-band with the option for remote mounting. Jill gets to use that one during the week, as I’m in the car for less than 10 minutes while she drives me to the train. The 207H will probably go into the new car when it comes, because of the remote mounting. I want to keep the install as clean as possible. That leaves the Buick as my daily driver, and without a decent rig. I decided to look for something that can do cross-band repeat for my next rig, and finally picked up a used IC-2350H the other day. It needs a little TLC, but nothing too complicated. As-is, it transmits OK on the 440 side, but it will not let you hear anything received, even though it IS receiving. The 2 Meter side is functioning great. Some quick troubleshooting shows that the volume/squelch pot for the 440 side is damaged, but fixable.
I tried the cross-band repeat function last night, which works great, even with the problem. I now have solved an issue that I was having in my home. We live in a bit of an RF hole, about halfway between my club’s Eastern, and Western Long Island repeaters. I can hit the Western repeater fine from the living room, with a rig attached to my homebrew wire antenna. Anywhere else in the house, though, I cannot. Sometimes during a few of the nets that I like to participate in, I need to be in the kitchen, or at my desk, or outside at the grill. With the cross-band repeater, I can use my little Baofeng UV-3R to transmit through to the Western repeater’s input, and still be able to hear the output directly on the Baofeng.
To work correctly this requires the use of the programming software on the Baofeng to set up a split channel (receive on 2M, and transmit on 440). I’m running the 2350H at 10 Watts, which is enough. It is passing the PL tone from the Baofeng so no need to encode again. The only feature I’m missing is tone-squelch on the Icom, so that un-authorized people don’t get in. Even if they do though, the chances of them using the correct tone to pass through to the repeater I’m targeting are slim. This weekend I’m going to test the receiving range of this setup with the mobile. I think this will even cure some of the dead spots that I have issues with in the neighborhood.
I intend to use this elsewhere too. We go on excursions up to the Adirondacks to my friend’s farm. Cell phones are marginal there, at best, and my Sprint phone just laughs at me when I try to use it. This would be a great way to communicate on his property. I can turn it on in the car, before we go hiking. I expect my son to also have his license soon, as well as Jill’s oldest, so we’ll have 4 licensed Hams when we go up there. Definitely a good investment.

Please stand by…
Have you ever had one of those days? Something that I refer to as The Shidas Touch. Wherein everything you touch turns to feces. I successfully managed to break my iPhone, Dell laptop, and a Garmin Nuvi 250 all in the course of about 12 hours. None of my radio equipment seems to have been affected by the condition, with my Icom dual-bander actually seeming to repair itself recently. The iPhone was an easy fix. Just a tethered reboot did the trick. I seem to always go one step too far when playing with things on my jailbroken Sprint iPhone 4. The Garmin was actually already broken, but I did manage to break it further. The person who borrowed this from my YL must have been trying to delete his history from the thing before he returned it, and managed to delete all of the maps in the process. Some research, and a few trial-and-errors brought the device back, and now is actually working better than before, but in the process I was pretty sure I had bricked the thing, and shoved it aside in favor of salvaging part of a good night’s sleep. The Dell, however, is a sad story.
I bring this up, because it is this same Dell laptop that was the processing muscle behind my testing of the Soft66LC4 that was sent to me to evaluate. In a fit of kindness, I was attempting to clone a USB flash drive that I use for radio programming, and accidentally hosed the partition structure of the Dell’s hard drive. How, you ask? Well, let’s just say that if you ever use a wonderful little program called Drive Image XML, don’t do it with any major distractions competing for your attention. It’s very easy to click the wrong thing, and BOOM!
I have managed to back up the damaged partition so that I can restore any settings in all of my radio software on there, but it is not rebuild-able at this point. I did manage to get it working for a little while using a program I like called TestDisk, but then when I tried to rebuild the Linux partition that I had also lost (along with some of Jill’s files), it killed all of the progress I had made earlier.
So, it’s done. Time to reload. So, for anyone who was waiting for more info on the Soft66LC4, We are experiencing operator difficulties. Please stand by. Good thing I didn’t try to work on the car that day!

Underway on Ham Radio Power
More than fifty Members of the Brazos Valley Amateur Radio Club (BVARC) in Houston, descended on Seawolf Park in Galveston Texas this past weekend to activate the radio rooms on two historic ships there; Submarine USS Cavalla and Destroyer Escort USS Stewart. This is part of the annual Museum Ships Weekend event sponsored by the Battleship New Jersey Amateur Radio Station. And the fifth year of BVARC participation.
This year, in addition to conventional SSB and CW communications, club members made more than forty QSO’s with other participants via satellite. In one instance, to the USS Nautilus, N1S, in Groton Connecticut; the world’s first nuclear powered submarine, whose first captain sent the historic message, “Underway on nuclear power.”
This year, ninety nine museum ships worldwide participated using mainly voice and CW. The Seawolf Park operation is unique as it is only one of two locations in the annual event that has two ships on the air from the same location.
Much of the radio equipment on these old ships no longer works due to age and lack of parts. So we have to bring our own radio gear on board.
We logged over 1,000 contacts this weekend with amateur radio operators throughout the US and Canada and as far away as Australia from Seawolf Park. The Park is an almost perfect venue for radio operations due to its proximity to salt water and lack of obstructions.
As the park is a public facility, all club activities this weekend were performed in full view of park visitors who were free to observe and ask questions. Brazos Valley volunteers also acted as guides inside the ship to explain the sights and sounds of radio communication.
This year the club decided to sponsor its own Texas Navy Certificate for confirmed contacts with all five Texas based museum ships. In addition to the Brazos Valley club, KK5W operating from the Cavalla and Stewart, the ships included Sailing Barque Elissa operated by the Tidelands Amateur Radio Society, N5E, the Battleship Texas Amateur Radio Station,NA5DV on the USS Texas in Laporte, Texas, and W5LEX, the South Texas Amateur Radio Club operating the USS Lexington in Corpus Christi. The club will verify the eligibility and award the certificate by comparing the log entries of the other participating ships.
The club also operated two VHF nets on Saturday and Sunday for local amateurs on 146.94 Mhz. The WA5CYI repeater has wide coverage and allowed us to include, NA5DV, Battleship Texas and N5E, Tall Ship Elissa, in addition to KK5W, representing the USS Cavalla and USS Stewart. More than 50 local amateurs checked in to the net over the two day period and logged contact with four of the five Texas based Museum Ships; the unofficial Texas Navy.
All in all this was a great event for the club. It demonstrated the power and flexibility of ham radio to the general public, it was a tune up field day and it was a public service to the community. The weather was great too!
Is the Baofeng UV-3R Mark II really modifiable to 220 Mhz?
The answer is yes, and no. Using the software utility available here you can stretch the coverage of your UV-3R Mark II. This
only works on the Mark II (dual watch display) and the new Plus model. There are two options for changing the coverage. You can stretch up from VHF or down from UHF. Only the UHF option seems to work. Now, before you run off and do this, let me pass a few warnings. First of all, the UV-3R is NOT designed to do this, so transmitting at full power on a band your radio was not designed to work on has the potential to fry something. Second of all, most users have put the output power between 1 and 16 milliwatts (yes, milli), and my tests concur with this. It does receive OK on 220, but not as well as it does on 2M or 440. The procedure can be a little complicated, but there is plenty of help at the UV-3R Yahoo Group.
So, does it really work? During my morning commute, my train passes south of my club’s main repeater site. Now this is on a rather high building, in one of the highest points on western Long Island, and is pretty much line-of-site for a 4-5 mile stretch of my train ride. I tested to see if I could key up our 220 machine, and it seems that the effective range was about 4 miles this morning. Now that was just keying the repeater up. I’ll have to check to see if I can actually be HEARD on it. For listening to the 2 or 3 220 repeaters near my office though, it works fine. Also, keep in mind that this was all done with the stock antenna, which is most likely far from optimal at 220 Mhz.
Once again, I can’t stress enough that if you don’t want to risk breaking your radio permanently, don’t try this. So far, my little radio has suffered no ill-effects, but your mileage may vary.

A Book of Ideas For New Hams
Noted amateur radio author and blogger Dan Romanchik, KB6NU, has released a new Kindle e-book titled 21 Things to Do After You Get Your Amateur Radio License.
Romanchik said that many people rush headlong into the hobby only to stall out. “The main reason that I wrote this book is that it was frustrating to me that so many people get their Tech licenses and then never do anything with them,” he said. “They never really get involved in the hobby for whatever reason. I am hoping that if they read this book — and actually try some of the things that I suggest — they will be inspired to really get into ham radio.”
If you have a Kindle or the Kindle app for iOS/Android, you can download his book for $2.99 from Amazon. There are also Nook and PDF versions available on his website. Don’t forget to check out his blog at http://www.kb6nu.com (and while you’re there, check out his No-Nonsense Study Guides!)
Soft66LC4 SDR – initial impressions
I received a Soft66LC4 SDR receiver for evaluation. The review of this radio will be in 3 parts, initial impressions, usage test, and full technical test. Here are my initial impressions.
The Soft66LC4 is the newest SDR receiver from Kazunori Miura JA7TDO. There have been several revisions of this inexpensive
SDR over the last couple of years. The evaluation unit came in about a week from Japan in a plain envelope with no documentation or software. You are expected to refer back to JA7DTO’s website for help. Although the setup is a bit complicated, it wasn’t too bad for me since I deal with a lot of control software that uses USB-to-serial connectivity. I was pleasantly surprised to find out that my Dell laptop’s internal sound card can process at 192khz, giving me a full 192khz of visible bandwidth.
The Soft66 is a bit larger than an Altoids tin. JA7TDO’s eBay store states that you have to finish the case yourself and drill holes, but it seems that he is doing this for you now. There is an SMA antenna connector, a mini USB port, and an indicator light on one end. On the other end is a 3.5mm audio jack, and a hole for access to an adjustment pot for RF gain. I found that my sample needed a slightly longer mini USB plug as the first one I tried did not stay in well.
Driver installation can be quite complicated but I intend to help him with this by writing up some easy-to-follow instructions. One issue that exists with this SDR for now, but will probably be resolved soon, is that there isn’t a way to control the SDR with WinRAD yet. You have to use the separate control application which makes the process a bit clunky. I believe that once more of these newer LC4 models are out there there will be support for WinRAD and other SDR Applications, as there were for the previous Soft66 radios.
Initial usage tests at my location were favorable, considering my lack of a decent antenna (about 10M of wire in a tree outside my window), and excessive RFI at my location. I hope to get out to a more remote site to perform the detailed usage review in a more interference-free environment. Coverage is from 500 khz to 70 Mhz. For now, the control app does not warn you if you enter a frequency outside that range, but simply crashes. Luckily, this does not lockup the controller, and you simply need to relaunch the application. I was able to receive MW AM stations, CW, SSB, data, and AM on the amateur bands, and plenty of SW BC. I did not try WinRAD’s DRM feature yet.
I’ll try to get this set up for remote access if possible, but for now, with no way to control it other than with the supplied application, I will hold off. Special thanks to Kazunori Miura for supplying the test sample so quickly, and to my friend WA2CDL, who offered to perform the technical testing.
On JA7TDO’s eBay store these radios sell for $108 plus shipping, and are fully assembled. Well worth the money as long as the proper DLL files are made available for using it with WinRAD. A more extensive test will follow.
