read moreLast night eBay sent me an e-mail saying it had located a UT-10 for me. I jumped on it! I've been looking for one of these for about two years. The price was right, too, so now I'll have 1.2GHz in the TS-790A in a couple of weeks! Oh …
read moreI'm considering doing a rover operation for the ARRL UHF Contest this August. I'm still trying to figure out where I want to operate (Shenandoah comes to mind) but I should have my 1.2GHz (23cm) transceiver up and working in addition to the 432MHz (70cm) so it should be …
read moreI got back from Cary, NC last night around 6:30P. It was an exciting but extremely exhausting weekend. The Tour de Cure went off with only a few minor problems but none really related to the communications operation (which is what I'm in charge of). I was pretty excited …

I had the pleasure of doing
a mini-DXpedition over the Memorial Day weekend on Hatteras Island. The
YL and I setup a 20m SSB station in the tent using a MFJ 20m SSB Travel
radio, a hamstick rotatable dipole, a 12ah battery, and a 18w solar
panel.
Overall, the test …

First you need the IM client called Pidgin. This client works …

The BBC is reporting that China censored Obama's speech on a number of websites. This is yet another reason why the Internet does not, and cannot, replace shortwave broadcast. Shortwave broadcast is very difficult, if not impossible, to block. Governments have tried in the past to keep their citizens from …
Opened the mailbox this afternoon and found my QSL from Victor Cuesta YV4DYJ of whom I worked on AO-51 back in September. Very cool. Glad I was able to make this contact using 5 watts and my hand-held station in my front yard.

Things I need to purchase:
I just worked a pass on AO-16. Heck yeah it was early. But having the bird all to myself at 5:45 in the morning means I get to test my antennas without stepping on anyone else. I did work N8OQ but it wasn't easy. And I'm not really sure …
read moreNow comes the interesting part. How do I hold up my antennas so they can twist and turn as required? I don't plan to be in the same location in two years so I don't want to do anything permanent. I currently have a 30-foot pole up next to the …
read moreThe most important part to a radio station is the antennas. You could probably lump in the feedline as well but I think I have that figured out for the moment.
So what antennas do I already have and what do I need.
Have:
I'm ready to take the next step. I have a set of azimuth and elevation rotators and I even have a 2M beam. I think it is time I get serious about my satellite operations. Not that I don't have fun working the FM birds via my HT and an …

Got a return QSL from EA6SX today. Before you say "You didn't have Spain?" you should know that this isn't exactly Spain. Turns out it this is from the Balearic Islands in the Med. Contact was made on 16 Mar on 17 meters.
Thanks Mike for …
