WD9EWK on Saturday @ Yuma hamfest, DM22 only...
by Patrick STODDARD (WD9EWK/VA7EWK) 22 Feb '09

22 Feb '09

Hi! The second day at the Yuma (Arizona) Hamfest was a very good day. More people were passing through the exhibit hall and visiting the AMSAT table along with the other tables and booths. Throughout the day, my satellite and ISS demonstrations were generally well attended. The hamfest officially opened at 8.00am local time (1500 UTC), and as the hamfest started I was already working an AO-51 pass. Then a large crowd followed me outside for a VO-52 pass around 1720 UTC. Thanks to KG7EZ, AA5PK, and W7JPI for following me around the downlink for our quick contacts. There was a scheduled ISS contact around 1820 UTC, through a ground station in California. I was outside the exhibit hall for that, picking up the signals around 1823-1824 UTC and hearing the remainder of the contact from that point. I was only using an IC-Z1 HT and my Elk Antennas 2m/70cm log periodic, with a loudspeaker plugged into the HT, which was more than enough to let the crowd hear Mike Fincke's side of the QSO. The ISS came by again around 2000 UTC, and the cross-band repeater was on. More QSOs then, as well as two SO-50 passes and an AO-51 pass around 0030 UTC to wrap up my demonstrations and the hamfest. At 0100 UTC, there was a barbecue dinner - very good food! During the day today, I had two other hams who helped cover the AMSAT table when I went outside for the demonstrations. Thank you Alex XE2BSS/N2IX and David XE2DAK from the Red Digital del Noroeste radio club in nearby Mexicali. This is the club that I gave an impromptu presentation for on Thursday evening, recently formed and awaiting the issuance of its Mexican club callsign. Along with Alex and David, two other members from the club came out to the hamfest to visit the AMSAT table and see the other stuff at the hamfest - Antonio XE2SIV and Eliseo XE2TPJ. There were lots of hams stopping by, many of them "snowbirds" from the colder parts of the USA and Canada that live in and around Yuma during the wintertime. Alex XE2BSS/N2IX has posted another web page with photos taken today at the Yuma Hamfest: http://www.xe2bss.org/yumahamfest.html Again, this is a "work in progress" as he goes through the photos he took along with other photos. The text on the page is in Spanish, so Babelfish or Google's web-page translation service can be your "friend" if you need it translated to English or some other language. In all, WD9EWK was on 6 different passes Saturday from grid DM22qq - 2 AO-51 passes using the normal 145.920/435.300 MHz V/U transponder, 2 SO-50 passes, and one pass each for VO-52 and the ISS cross-band repeater - along with hearing the ISS school QSO. I logged 43 more QSOs today, for a total of 61 QSOs at the hamfest. As of tonight, I have logged 152 QSOs from grids DM22 and DM32 in Arizona, California, and Baja California since I left Phoenix on Wednesday. So far, a fun trip - with one more full day to go before heading home. More activity is planned from somewhere on the FM birds and *maybe* VO-52/FO-29, probably still in DM22, on Sunday. A special thank-you needs to go to Richard KC2LGR and the Yuma Amateur Radio Hamfest Organization. I was approached last summer by members of this group, asking if I could bring an AMSAT table to this hamfest. Richard and the group allowed me to set up a table, display AMSAT information and merchandise, and were very helpful for whatever I needed over the two days. The location in Yuma - near a freeway and within 3 to 4 hours' driving for many hams in Arizona, California, as well as northwestern Mexico - could help things improve in the coming years. I had good crowds for most of the demonstrations, even on Friday. And did I mention the great food at the barbecue this evening? :-) This was a good hamfest, put on by a lot of hard-working people in the ham community in and around Yuma, and I hope to return in 2010. Good night, and 73! Patrick WD9EWK/VA7EWK - Calexico, California http://www.wd9ewk.net/

IC-821 HELP
by ab0xe 21 Feb '09

21 Feb '09

Hello I am running an IC-821 with Satpc32 software Occasionally when I am using 2 meters as the uplink the radio will jump down exactly 400k cycles on the transmit The software shows the correct freq, but the radio is off by minus 400K To prevent this I usually have to turn the CAT off and use the radio manually to track the freq. It certainly is not the end of the world to do this, but I sure would appreciate any advice that would allow me to keep the CAT connected. Thanks from cold and snowy MN Steve Howard AB0XE

The last opportunity I had to listen (while ISS was in APRS mode), it seems like I only heard a few packets downlink, but they weren't appearing in the APRS-IS. I only copied one or two beacons, neither was mine. I couldn't tell if it was my station, the ISS digi, or just that the Igates of the southeast US were all asleep... Checking the map tonite tho, I see that the most recent activity was a few days back. I'm afraid that with the irregularity of the schedule, some are finding it difficult to dedicate the resources to that frequency 24x7 ... I hope to have mine back on the air soon, I hope there will be enough in the schedule to keep it on freq. /;^) -- <- Licensed in 1976, WB5RMG = Alan Sieg * AMSAT#20554 -> <- http://www.somenet.net * http://wb5rmg.somenet.net -> <- http://www.linkedin.com/in/alansieg * My 'Day Job' ->

Can I cross-band my way to L-band BBS?
by Greg D. 21 Feb '09

21 Feb '09

This may be too crazy of an idea, so I should probably ask before I put too much effort into it... The only 9600 BPS packet capability that I have is with my Kenwood TH-D7A, but the BBS system on AO-51 is currently in mode LU, and now we hear that CO-65 will be doing the same. I have L-band capability in my Yaesu 736R. Would it be possible to link the two? AO-51's downlink is on 70cm; I'd need to use 2m as the link between the radios. D7 listens on 70cm, and transmits on 2m. (I believe the D7 can work split band on packet, right?) The 736 listens on 2m and transmits on 1268. Since the 736 can't do "cross band repeat", in the traditional sense, my thought is to use the satellite mode on the 736 and cross-connect the audio at the data in/out jack and use the VOX on 1268 to key the transmitter. I can think of two issues with doing this. First, is the VOX operation going to be quick enough to get the whole packet through? I'll probably need to extend the transmit delay to compensate; how long? Second, is the audio response going to be adequate going in and out of the Data jack? It's supposed to be right off the demodulator, without any audio shaping, but the rig is unmodified in this area and I thought the 736 didn't do 9600 very well out of the box. I've got the 736 hooked to the computer for Doppler tracking; at least that part should work. Oops, no, not quite; I'd need to modify the PC's Doppler control client so that the 2m side stays static. Not a big deal. So, is this worth trying? (I know, buying a "real" TNC would be a lot easier...)
