The Rhythm of CW

January 01, 1970 Dan KB6NU

Try these to get a feel for how rhytmic CW can be:

I got all of these from the wonderful Elecraft mailing list. Just click on the list items to download a zipped mp3 file. I'm sorry about the zip, but it was the only way to make the file small enough to be easily downloadable. Zipped, these files are about 60 kbytes; unzipped, they're over 2.5 Mbytes.

Balun Test Method

January 01, 1970 Dan KB6NU

Here's another thread from the wonderful Elecraft mailling list:

Vic, K2VCO writes:

I made a simple 1:1 receive-only balun for 160 meters by winding 9 bifilar turns of no. 24 enameled wire on an FT37-77 toroid. I connected a 50-ohm resistor to the output and my MFJ antenna analyzer to the input. On 1.8 MHz it shows a resistance of 50 ohms, an inductive reactance of 1 ohm, and an SWR of 1.0:1.

My question is, did I make a 'good' balun? Are there other tests I should do?

New Rig at KB6NU

January 01, 1970 Dan KB6NU

For the past several months I've been using an Icom IC-746PRO that was donated to ARROW. I've been feeling a little guilty about using it for so long, so when someone offered to sell me a unit he bought in February, I jumped at the chance. He sold it to me for $1250, about $300 less than what they're going for these days.

I really like the rig, although to be honest, I don't have much to compare it with. The last rig I used regularly was an old IC-735, which I also like a lot, but it doesn't have the bells and whistles that the 746 has.

More kits than you can shake a soldering iron at

January 01, 1970 Dan KB6NU

A couple of months ago, a group of us were talking on the repeater, and the talk got around to building stuff. One of the guys said, "You can't really build anything anymore." I almost fell out of my chair. There are all kinds of kits out there that hams can build.

So, yesterday, I gave a presentation to our club on kits and kit building. After the short presentation--whichi I've included below--we had a show-and-tell of kits that were brought in by the members and were in various stages of completion. (Pictures coming soon!)

So, what are you going to build next?

QRP Newsletter Now Available in CW Format

January 01, 1970 Dan KB6NU

Recently, Ray Goff G4FON added MP3 generation to his brilliant Koch CW Trainer program. Now, Nigel Gunn G8IFF/KC8NHF is using that feature to make available the newsletter of the Flying Pigs QRP Club International--Bacon Bits Quarterly (BBQ)--in CW format. The files are a bit on the large side--part 1 of the April editorial was a bit over 20 Mbytes, but the code is beautiful. I've suggested to Nigel that he may want to zip the files as that makes them quite a bit smaller.
