Learn how to work the FM ham satellites
Many hams don’t have the financial resources to buy some of the more exotic equipment you see in the full-page QST ads. Don’t worry, you don’t have to feel left out! What almost every ham DOES have is a dual-band HT. Clint Bradford, K6LCS, has created an excellent THE go-to resource to show you how you can easily work the FM birds with minimal equipment — most of which you probably already have! His site is truly a wealth of information.
He shared this with me:
It has been my mission in life the past 8+ years to show those who have never worked an amateur satellite that they CAN do it – with equipment they probably already own. I mean, when I first saw an AMSAT table at a hamfest several years ago, I just walked on by, wrongly believing that I needed 100W of TX power, multiple Yagis on the roof (which has led to divorces in my state), and that expensive Yaesu rotator.
Clint lays it out step-by-step:
- Radio options
Clint uses a Yaesu FT-60R with a speaker mic, but you can use most dual-band HTs that feature the ability to program “split frequencies.” Ideally, you could use a second radio (or scanner) and work in full-duplex mode. According to Clint, there are discontinued HTs which support full-duplex including the Kenwood TH-D7/TH-D79, Icom IC-W32a, and the Yaesu FT-470/FT-51/FT-530.
- Antenna options
Clint recommends the Arrow Antenna Model 146/437-10WBP or Elk Log Periodic Model 2M/440L5, but these very nice (but expensive) antennas aren’t your only option. He suggests that you could build a simple and inexpensive tape measure beam with very acceptable results. Just want to listen? Well, Clint shares that although it takes more patience and finesse to work satellites with “lesser” antennas, one of the first 2-meter reception reports from the ARISSat-1 was from someone using the stock antenna on his Yaesu VX-9 HT!
- Find an “easy” satellite
Clint recommends starting off with SO-50 or even the ISS (International Space Station). He has a great satellite schedule page on his site which lists the current status/availability of each bird and the necessary frequencies and CTCSS. Of note, some birds may require the transmission of a certain tone to activate a timer. After that, a different subaudible tone is used for the duration of the QSO. He does note that SO-50 can be a little “finicky” — for best results, work it full-duplex.
- Track the satellite
You have to know both when the satellite will be “visible” to you, and where you’ll need to point your antenna. Clint has a tracking page on his site which lists some of the programs and apps he recommends. While there are a variety of commercial options, he offers some good free options including AMSAT’s Online Satellite Tracking and Heavens-Above.
- That’s it! Have fun!
If you haven’t already done so, download and print his 4-page PDF guide called Work FM Satellites with your HT! to use as a reference. Thanks for the hard work, Clint. We appreciate it!

SSN data file goes AWOL
I’ve not updated the VOAProp file ssn.txt for a while as some irritating health issues kept on getting in the way. I thought I would have a try today butit seems the NOAA data file Iused to update it from has moved to a new address. Does anyone know where it has gone to?

WARC bands
The WARC bands are nice to explore. This afternoon I worked on 12 meter A92GE from Bahrain. I did heard several stations from Bahrain. Also worked TF3JB from Reykjavik, Iceland. On 15 meter I had a nice QSO with VA2PW Peter (Pierre) from Quebec, Canada.

BCD436HP Sentinel Software won’t read SD Card
BCD436HP Sentinel Software won’t read SD Card
Like many, I was excited to know that Uniden was coming out with a new line of scanners. As someone that owns many of their products as well as their HomePatrol I have really liked the direction they have been going with easy of programming (like GRE has done for some time) and the ability to use GPS to automatically update locations is another great option.
Well, you have read enough about the scanner and I will do my own review at some point, but this post is about the fact that there has been a nagging issue that I have seen others have and unfortunately, I ran into the same issue.
For some reason Uniden did not format their SD Cards in the same format so there has been some of us with both the UNIDEN BCD536HP as well as the BCD436HP that have had SD Card unreadable or not recognized by the Sentinel software. I have read many posts out there about people getting frustrated and sending theirs back as defective units which I was concerned about when I read this, but alas after trying several cables, different computers with Windows 7, Windows 8 and even Windows 8.1 I found a very simple solution.

Snow bound – not quite.
Yesterday was a day spent working from home – as much as I could via my company issued laptop. We received about 14 inches of snow.
I am back at the office today and am looking forward to the upcoming three day weekend. There’s lots of Amateur Radio stuff to look forward to.
1) This weekend is the big ARRL CW DX contest.
2) This weekend is the monthly Polar Bear Moonlight Madness Event
3) This is the weekend my KXPA100 gets built and put online.
I am NOT looking forward to another 2-4″ of snow tomorrow, along with the necessary snow removal chores. BUT Spring is closer than farther away at this point, so you have to keep your eyes on the prize.
I did manage to get on the air last night for the 80 Meter QRP Fox Hunt and bagged both Foxes – Dave N1IX in NH and Rick NK9G in WI. I was able to get on between bouts of thundersnow. Yes, that’s right – thundersnow. As the big Nor’Easter rotated around, the rain that had started falling changed back to snow as the low pressure system started siphoning cold air. The warmer/colder air mix started a little battle which generated a few instances of lightning and thunder during a snow event. Not common, but not the rarest, either.
I do have to admit that I was spoiled rotten by the last few years of drier, milder Winters that we have been experiencing. This year, we have made up for that in spades, and I am more ready for Spring than I have been in a while!

Bloody Proprietary Connectors
I came across this video rant by David L. Jones on the EEVblog concerning proprietary cables on consumer devices. I agree with him completely. Warning: some language not suitable for kids.
Unfortunately, if you look at ham radio gear, we are in even worse shape than the consumer market. Heck, even the freaking microphone connectors are unique to each manufacturer.
