SDR Forum at Dayton Hamvention
by Robert McGwier 26 Mar '09

26 Mar '09

The SDR Forum at the Dayton Hamvention is Saturday 11:15 AM to 1:30 PM May 16. This is the ARRL National convention as well so it should be well attended. Because of missed emails, etc. (I was left off the email addressees so I got none of the emails) we are now in a rush. The initial list, etc. is supposed to be in DARA hands by April 1. This needs to be dealt with ASAP. I will contact some "you should" directly but I am soliciting 15-20 minute talks. I need at least an indiciation of willingness to speak, a few sentence abstract, and your willingness to be flexible in the timing as Irush this together. Thanks Bob McGwier ARS N4HY

ISS and shuttle viewing
by Luc Leblanc 25 Mar '09

25 Mar '09

On the 0005Z March 26 (2005 EDT on the 25) i just watch ISS lead by Discovery dimmer and slightly below ISS. A great space mechanic lesson an orbital body reducing his altitude increased his speed or it's an optical illusion? Physics has never been my taste of tea but always nice to watch passing space things over us and in bonus our seasonal wild white goose and wild duck and birds migration heading north with their usual sound. (resting and feeding place about 45mn from here see: http://www.pbase.com/descar/ornitho). If clear evening sky remain i will try some photos of the twin moving star "-" Luc Leblanc VE2DWE Skype VE2DWE www.qsl.net/ve2dwe WAC BASIC CW PHONE SATELLITE

Re: software for two-rig doppler control?

Hi Bill, SatPC32 will let you run two different rigs at the same time. This works well if you use one to TX and another to RX, using SatPC32 ver 12.8 Lately, I have been wanting to simulaneously control 2 radios--both with TX and RX. So, what I do is run a second copy of an older version of SatPC32 (ver 12.7). You can install the older version into a different location and set it up to run only the radio (not track box). I don't think it's possible to run two copies of 12.8 because of the install/default locations for the data files... Fortunately, 12.7 keeps the files in the same directory as the installed program, so you can run as many copies of that as you want! It takes a bit of work to get 2 copies running and configured correctly, since you have to configure them separately. But the files with frequency info, etc. can be copied so they use the same frequencies etc. It's not too bad, really, given the benefits. Why would I want to do this? I have two rigs I want to control...TS-2000X and TS-790A. This lets me hear both AO-51 repeaters at once (or do digital/telemetry on one, voice on the other), let's me use one for S-band receive, and so on. It's actually quite handy to mix/match transmitters/receivers. 73, Mark N8MH -------------------------------------------------------------------------------- Subject: [amsat-bb] software for two-rig doppler control?

Hi All, Anyone know if you can purchase a G-5500 control box without the rotator? I've been trying to ask Yaesu, but phone messages and emails have gone unanswered... Thanks, Matt KF6RTB

Re: Slow Scan

Try downloading "MMSSTV" and install it. Plug a patch cord from your earphone jack of the radio to the mike jack on your PC, and regulate the level with the volume control on the radio. As I recall, without doing anything else, you should be able to copy pictures. If there's no satellite and you want to test it, try listening to 14.230 on 20 meters. There are quite a few SSTV'ers sending on there daily. This thing is VERY easy to use ! Even I figured it out. And I am NOT a computer geek by any means. One other note: MMTTY is for RTTY. DIGIPAN is for PSK31. They all work in the same simple way (for receiving). You'll need another patch-cord to do the transmit part! 73 JOhn K6YK On Tue, 24 Mar 2009 21:17:18 -0400 WB2LLP <wb2llp(a)optonline.net> writes: > AO-51's handlers are doing a very nice job of presenting us with > several different satellite modes.

Slow Scan
by WB2LLP 24 Mar '09

AO-51's handlers are doing a very nice job of presenting us with several different satellite modes. This week it is an opportunity to try Slow Scan TV. Now it would be very nice if someone from the Slow Scan community would tell us how to receive the pictures and once we have done that, how do we send a picture. We only have a week to play with something which is very different for some of us, so let us not waste any time. TNX es 73 de WB2LLP Gene ARRL 1139432 AMSAT 33183
