HT-D72a connector
by Scott Smith 23 Feb '12

23 Feb '12

Hi folks, just updated my h/held to a HT-D72a as my FT530 as it’s getting on in age. I liked the BNC connector on the FT530 it was easy to connect to my mobile antenna, but the HT-D72a uses a flimsy SMA connector. does anyone used this radio as a mobile? what kind of connection to your mobile whip?. Any help appreciated. 73 de VE6ITV Scott

The used 450 was less than the motor from Yaesu parts, and I sold the control box and housing on Ebay for almost as much as I picked the whole thing up for. 73, Drew KO4MA

Linux has the software packet modems and AX.25 support in the kernel (though you usually have to reompile the kernel to access them on modern distros). I'm not sure how to setup Linux packet these days, as the howtos are very old. I recall experimenting with the Linux soundcard modem many years ago with a lot of success. 73 de VK3JED / VK3IRL http://vkradio.com

Linux software TNC

I have a few Windows computers running the AGW Packet Engine as a Software TNC. I would like to find something that provides similar functionality but for Linux. I am hoping someone out there uses a Linux computer with a software TNC for satellites, but if nothing else would like the find out what people are using software or hardware. 73 Anthony Odenthal KE7OSN President Amateur Radio Club at OSU

two more Yuma Hamfest videos
by Patrick STODDARD (WD9EWK/VA7EWK) 22 Feb '12

22 Feb '12

Hi! Last night, I made a video of an AO-7 pass I worked at the Yuma Hamfest on Friday (17 February) afternoon. Since I only had the satellite audio from that pass, I combined that with a series of photos and graphics to make a "movie" out of that. I also have a video that started at the end of that pass, when my "cameraman" Uriel XE2VAS/N2IY came over to my operating position outside the main hall. After the pass ended, I was answering questions from the crowd that had stuck around. Those videos are now posted online at: http://www.youtube.com/watch?v=4FPgM1jZxc8 (AO-7 pass) http://www.youtube.com/watch?v=5LiHxAbinwk (discussion after the pass) Like the other videos I mentioned in a -BB post yesterday: http://amsat.org/pipermail/amsat-bb/2012-February/040308.html these two videos were also made in 720p HD. 73!

Disruption in AMSAT-BB, ANS, SAREX
by Paul Williamson 22 Feb '12

22 Feb '12

For reasons we don't fully understand, there was an outage in the AMSAT-BB, SAREX, and ANS mailing lists for the last day or two. I am not sure whether any messages were lost. I think the problem has been dealt with. If you're reading this message, then probably it has. 73 -Paul kb5mu(a)amsat.org

K7UGA videos from Yuma AZ (17-19 February)
by Patrick STODDARD (WD9EWK/VA7EWK) 21 Feb '12

21 Feb '12

Hi! While I was in Yuma AZ over the weekend, I made videos of a few passes I worked as K7UGA. Three of the following links were from passes worked outside the main hall at the Yuma Hamfest on Friday or Saturday. The fourth video was of a VO-52 worked from the Yuma Territorial Prison on Sunday morning, after the hamfest closed. Thanks to Uriel XE2VAS/N2IY for working the camera for the hamfest videos. I was by myself for for the VO-52 pass, so the camera was on a tripod with my external speaker near the camera supplying the satellite audio. Here are those links.... SO-50 pass on Friday (17 February) morning at 1751 UTC: http://www.youtube.com/watch?v=BKaIKgjuSMM AO-27 pass on Friday afternoon at 2032 UTC: http://www.youtube.com/watch?v=AIA_VANTdpQ AO-27 pass on Saturday (18 February) afternoon at 2004 UTC: http://www.youtube.com/watch?v=YiXTjgD5nD8 VO-52 pass on Sunday (19 February) morning at 1538 UTC: http://www.youtube.com/watch?v=l0AAB3A7Xy4 I worked an AO-7 pass Friday afternoon, but it was not recorded as a video. Only audio. There was a nice question-and-answer session after that pass that was captured on video. I plan to make a slideshow using photos from the hamfest and other graphics, and combine that with the AO-7 audio to upload tonight. I will also upload the video of the discussion after the pass. The VO-52 pass Sunday morning was the last pass I worked as K7UGA. I had previously uploaded the first pass I worked as K7UGA, an AO-7 pass on 13 February from my back yard in the Phoenix area, which is available at: http://www.youtube.com/watch?v=790OQThYtX0 73!

K7UGA wrap-up
by Patrick STODDARD (WD9EWK/VA7EWK) 21 Feb '12

21 Feb '12

Hi! Thanks to all the stations that worked the K7UGA special-event station in the past week, helping the Central Arizona DX Association in its commemoration of the Arizona statehood centennial. Between Tom NQ7R and me, we made 122 satellite QSOs. Tom, who worked satellites a long time ago and is coming back to them, worked a handful of passes I didn't work at the end of the week. He also worked a VO-52 pass I was on Sunday morning. I was able to get WD9EWK into the K7UGA log, when Tom worked me as K7UGA. :-) I was able to make at least one QSO on every pass I attempted as K7UGA, and there was one FM pass that saw 14 QSOs logged! Tom worked his passes from his home in Casa Grande AZ (grid DM42). For passes I worked at the start of the week through Thursday afternoon, I was operating from DM43 here in the Phoenix area. For the passes I worked Friday and Saturday, I was at the Yuma Hamfest. On Sunday morning, I parked next to the Yuma Territorial Prison State Historic Park overlooking the Colorado River. Both Yuma sites are in grid DM22. Besides the satellite operating Tom and I did as K7UGA, other CADXA members activated the call on all HF bands along with 6m and 2m from locations all over Arizona. I even used the call from the AMSAT table inside the main hall at the Yuma hamfest Saturday morning on a cross-band repeater that flew with a high-altitude balloon. I made QSOs as K7UGA with a couple of stations outside the hall at the hamfest and two others in different parts of Arizona through that repeater. Initial reports show that K7UGA made over 6500 QSOs on all bands including the satellites during the past week. Whether you worked K7UGA on the satellites, on HF, or in both places, thanks to all who took the time to call K7UGA. It was a fun time working as K7UGA, especially hearing some of the (quick) stories related to the call's original holder, Barry Goldwater. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/
