1,2g ts2000 Module
by Perry Yantis 29 May '08

The 1.2 module must be installed by Kenwood. I purchased my TS 2000 with the module installed and I have had no problems. Perry WB8OTH pyantis(a)earthlink.net

RS-30 second transponder
by John Price 29 May '08

29 May '08

I worked the pass over FM07 around 22:57 5/28. Very easy to access and hear on my D700 mobile and duel band vertical on the roof. Myself and 3 others had it to ourselves. That is nice for a change. Thanks to the command for this mode. 73's << John -- N4QWF Amateur Radio Operator AO-7,AO-16,AO-27,SO-50,AO-51,VO-52 Internet N4QWF(a)AMSAT.ORG Formerly KC4AHW VK3FEZ Amsat Member #27845 DXCC #33,478 VUCC SAT #135 WAS SAT #296 51 on 51 #13 LON -79.25 LAT 37.45 Grid FM07 >From the Foothills of the Blueridge *Life should not be a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming - "WOW, What a ride!"

Grumbles about RS-30 [was: JUBILEE and other frustrations]
by John Mock KD6PAG 28 May '08

28 May '08

Hey, folks, whether RS-30 has some kind of transponder is just rumor and speculation at this point. I feel (and only represent myself) that it's very bad form to condemn or harshly criticize the builders of this satellite, at the very least, until we know what it's capable of. Maybe it won't do voice, but even a digipeater at that altitude would be a very nice thing to have. -- KD6PAG (Networking Old-Timer, Satellite QRPer)

Re: newbie question Icom 910H & LEO antennas
by John Kopala 28 May '08

28 May '08

Jim: Ron writes about how he uses the AFC. I tried that. It's pretty cool, but you still have to tune to uplink for doppler. The downlink track perfectly. I used to have the memory channels set up, actually still do, but now never use them. But, with SATPC32, the whole process is automated and works for the SSB birds too. I only have to touch the IC-910H radio for a four things: 1. Change the PL tone to turn on the SO-50 satellite transmitter. Then change back to the normal PL. 2. Tune across the bandwidth of the linear transponder SSB / CW satellites to locate other hams scattered across the transponder passband. 3. Track other SSB operators who are not using doppler control. 4. Turn on or off my preamps when needed or not needed. Automation is great. It controls my rotors Ken Pro KR-500 and HAM-IV (with custom home made enhancements to the rotor controllers), my G-5400B AZ-EL rotors I am using to build a portable setup, tunes for doppler, and can be set up to automatically switch to selected active satellites, so all you have to do is talk and log your contacts. A voice recorder helps there in case you miss something. I still haven't found a way for it to send out the QSL cards automatically, YET! Oh yes, I looked at some of the reviews in eHam. There were complaints about not being able to set separate RX and TX PL tones - The reviewer needs to read the manual. You do have to be careful. For example, with SO-50, if you want to turn on the satellite transmitter with a 74.0 PL tone, you have to know what you are doing. There are 4 different PL tones that can be set. If you change the wrong one, the satellite won't turn on. You choosing between Main and Sub band and between RX and TX PL for each of those. I noticed another reported problem which I do not recall, but that was also a case of reading the manual. Whatever you decide to do, have fun. Don't settle for just doing the FM birds. They are easy. They are a great place to start. Try this progression: AO-51 (Easiest FM bird), AO-27 (downlink is higher than published by about 3.5 KHz and it is only on for 7 minutes over North American Lattitude), SO-50 (need PL), VO-52 (Great SSB bird, LSB Uplink, USB Downlink), AO-16 (FM Uplink, DSB downlink - Off lately), and AO-07 (SSB, In daylight only, moderate elevation helps). Circular polarized yagi antennas with automated elevation and azimuth control and some preamps pretty much complete that station and will let you work just about anything as long as you don't have any mountains or other obstruction in the way. John N7JK >I have used the IC910H for several years on the birds and have found it very friendly to the FM birds. I use two non satellite memories for each FM bird. One for the VHF uplink and one for the UHF downlink. One the UHF memory, I store it with AFC enabled so the radio automatically tunes for the doppler shift on its own. >Please check my web site at www.ka4kyi.com for more info on how I operate the birds using the IC910H and other radios.

Re: AO-51 2nd repeater operational
by Dennis Griffin 28 May '08

28 May '08

435.300 downlink? I thought it was 435.150. Thanks for the reply. I've heard ISS just fine with the same setup, but I see that AO-51 is a bit over twice as high. I'll try open squelch next time and Doppler tuning on rx. I don't understand, however, why I didn't hear myself on the nominal 435.150 at peak of pass, unless rx is actually 435.300. I have the W-32 set for Full Duplex, so receive mute wasn't active. 73 de Dennis KD7CAC On May 28, 2008, at 9:23 AM, Andrew Glasbrenner wrote: > You should try to listen with the squelch off, the satellite signal > is usually not strong enough to crack it.

Re: SatPC32 12.8 released
by Ronald G. Parsons 28 May '08

The version of 12.8 for ISS (SatPC32ISS) does not start with the QTH/Registration dialog. I can find no way to enter my Lat/Long. I did follow the instructions for upgrading from 12.7. Also there is no Setup menu. Is there something I am missing? Ron W5RKN > Date: Wed, 28 May 2008 08:30:07 -0500 > From: "Alan P.

RS-30 receive
by John Price 28 May '08

28 May '08

Just copied the last pass of the satellite RS-30. The CW signal was very strong here in FM07. Copied LOS right down to 5 degrees. The doppler was about 5 kc higher than expected. Looked to be about 435.317 center. Sure wish that thing could talk. 73's << John -- N4QWF Amateur Radio Operator AO-7,AO-16,AO-27,SO-50,AO-51,VO-52 Internet N4QWF(a)AMSAT.ORG Formerly KC4AHW VK3FEZ Amsat Member #27845 DXCC #33,478 VUCC SAT #135 WAS SAT #296 51 on 51 #13 LON -79.25 LAT 37.45 Grid FM07 >From the Foothills of the Blueridge *Life should not be a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming - "WOW, What a ride!"
