Being the greedy sot that I am…

…I’m going to try another way to “monetize” this website. What I’ve done is to add a page thats list ham radio products sold on Amazon. If you purchase a product on Amazon using one of the links there, I’ll get a cut. You can get to that page by clicking on the “Ham Stuff (from Amazon)” link above.

Taking that a step further, I’d love to get your suggestions for products to list there. You don’t have to have purchased it on Amazon, but it needs to be sold by Amazon. Please feel to either e-mail me your suggestions or enter them in the comment section below.

A quick comparison of the Baofeng UV-5RA and Wouxun KG-UVD1P

About eight months ago, I purchased a Wouxun KG-UVD1P two-band HT. Overall, I’ve been very happy with it. Last week, I purchased a Baofeng UV-5RA. Apparently, Baofeng is coming out with a new model soon, and as a result, are trying to dump these units. I bought mine for $30 from some vendor selling through Amazon, although now it looks like the cheapest price is $33.55.

Wouxun KG-UVD1PBaofeng UV-5RA

It’s been interesting to compare the two units. This is by no means an exhaustive comparison, but just a few things that hit me from playing with the Baofeng for the last couple of days:

  • Programmability. As is commonly noted, the Wouxun is much more easily programmed than the Baofeng. It was relatively easy for me to figure out how to program the memory channels of the Wouxun. So much so that I decided not to purchase the programming cable. I still have not been able to program the memory in the Baofeng. Unlike the Wouxun, you have to separately program the transmit frequency and the receive frequency. I still have not mastered this procedure.
  • User documentation. The user documentation for the Wouxun is much better than the documentation for the Baofeng. The Wouxun comes with both a user manual and a quick reference card. The Baofeng come with a very thin manual that doesn’t seem to include instructions on how to program repeater frequencies into the memory channels.
  • Voice. Both radios can be programmed to announce, in either English or Chinese, things like operating mode and memory channel. The Baofeng voice sounds much more like a computer generated voice. The Wouxun English voice has a notable Chinese accent.
  • Antenna. Since I purchased it, I’ve only been using the  antenna that was supplied with the Wouxun. It seems to perform pretty well. I’m not so impressed with the Baofeng antenna. Not only does it not do a good a job as the Wouxun, it actually gets a little warm when I transmit on high power. I’m going to have to replace it.

All things considered, I’ve decided to do one of two things with the Baofeng. I’m either going to pass it on to one of my Tech class students or hack it like KK6BWA has done. I think that either would be a worthwhile thing.

Lack of standardization holding back amateur digital communications

Via Twitter, I recently found out that Yaesu had introduced a new digital communication system—called System Fusion—at the ARRL/TAPR Digital Communications Conference in Seattle, WA. When I asked KE9V, the guy who posted this announcement to Twitter whether or not Fusion was going to be more than a niche product, he replied, “I think it’s a long-shot at best. ICOM has dumped a lot of cash in D-STAR and now years later it’s just catching on. Tough road.”

Compounding the fact that Yaesu is late to the party is the fact that the radios are probably going to cost an arm and a leg, just like the D-STAR radios. Call me an old fart—and I have been called that and worse—but I just don’t see where the digital features are worth the extra bucks. (I would be happy to be convinced otherwise, though. Please feel free to comment on this below.)

Wouldn’t it have been nice if Yaesu and Icom, and maybe even Kenwood, had gotten together and developed a digital communication standard that both companies could support? Not only would have it made it more palatable to invest in such a radio, I bet those radios and repeaters would cost less than the current D-STAR and Fusion offerings. That’s just what happens when companies adopt standards.

As Bob, K0NR, tweeted, “File this under ‘missed opportunity.'” I agree.

p.s. I wanted to include a picture of the system, but the Yaesu website doesn’t yet have any yet on their website. There is, however, a YouTube video of the DCC meeting at which Yaesu introduced the product.

LEO satellite tracking in your backyard. Learn how one guy built his own satellite tracking system in his backyard.

The rise of the online circuit-design collective. Though still in the infancy stage, design and simulation tools that run entirely in the browser are pushing their way onto the EDA landscape. The ultimate goal is that they become essential players within the realm of professional design.

Test and measurement  turns to open source, Kickstarter. The field of test and measurement is set to benefit from open-source software applications if a Kickstarter fundraising project is successful. The Red Pitaya is a credit card-sized, reconfigurable measurement board with 60MHz of input bandwidth and an onboard Xilinx Zinq FPGA to perform signal processing.
