Have you used SO-50 before? It's not always easy to hear, even with large beams. However, it hears excellently. Before the 74.4 command was made public, I used to enable it automatically with a 2 watt HT and packet beacon every 3 minutes, to an omni. 73, Drew KO4MA -----Original Message----- >From: Peter Wilson <protest(a)virginmedia.com> >Sent: Jan 21, 2014 3:50 PM >To: amsat-bb(a)amsat.org >Subject: [amsat-bb] SO-50 Acquisition > >Hi all, > > > >We had a northerly pass of SO-50 earlier today and I was unable to switch >the timer on, get any response, or hear anyone else. > > > >I used the 74.4 Hz sub tone to arm the timer but nothing.

SO-50 Acquisition
by Peter Wilson 21 Jan '14

21 Jan '14

Hi all, We had a northerly pass of SO-50 earlier today and I was unable to switch the timer on, get any response, or hear anyone else. I used the 74.4 Hz sub tone to arm the timer but nothing. I have 100 Watts available to steerable beams, so signal strength is not the issue. Is this bird difficult to open? Thanks Peter G8KEK

Scott, Frank, K4FEG here, I do not know if this would applicable to your situation, but while I was having control issues with my Icom Ic-910H and SatPC32, I reached out to Erich (writer of SatPC32) about the issues and he told me that some of the cables and other interface modules (USB/Serial adapters) need to have the /*FTDI chip set*/ in them, /*I had to search for a specific type of USB/Serial adapter that had the FTDI chip set in it.*/ Once I got this adapter, and plugged it in on my Windows 8 and 7 PC's, both operating systems instantly recognized the device and loaded the proper driver to make the adapter work. /*Erich explained that the PROLIFIC chip set, which is common in North America seems to have an issue with his program.*/ Another note is that there may be a firmware update for you Kenwood. I have had others tell me that their TS-2000 would not properly control with SatPC and when they got the various firmware updates for their specific model radio, it helped to resolve their control issues. I do not know if this information is of help or not but I thought that it might, you may post your question on my BB, Star-COM.net, if you like. My bb tries to cater more to real life situations and operations on the satellites and working with operators and rovers to facilitate working new grids on the "birds" you are most welcome to come visit there if you wish. 73 & best regards, Frank K4FEG

145 MHz signal blocking 435 MHz downlink
by Gabriel - EA6VQ 20 Jan '14

20 Jan '14

Hi all, I have a coupling problem in my station when trying to work FO-29. My 2m signal is completely blocking the 435 MHz downlink, and so I can't hear my signal off the satellite. I guess it must be something related to the distance between the two yagis. (I use the terrestrial horizontal yagis you can see at http://www.dxmaps.com/jm19hn.html ). With mode-B satellites there is no problem. I have tried it with two different 435 receivers, and it's exactly the same. Anyone has had this problem o have an idea of the possible reason? And what is more important, of some way to solve it? Thanks for any possible help. 73.

AO-73 question
by Todd Bloomingdale 20 Jan '14

20 Jan '14

I'm interested in trying to receive the AO-73 telemetry. Currently, I'm not able to SB, so I know that the transponder is out of question for me. But is a SB radio needed for the telemetry? Todd Bloomingdale- KC9LOX Tomah, WI

AO27.org

For those of us who occasionally check on the /*status of AO27*/, I emailed /*Michael, N3UC,*/ and he told me that they have /*had a server crash */and are in the process of getting it back up. No additional information on the "Rescue Operations" for AO27 at this time. Keep your fingers crossed folks! We may yet get AO27 back on the air. Many thanks to the AO27 Group and their efforts to recover AO27 for operations. We really appreciate your efforts! 73 ALL FRM; K4FEG Starcom/SATDX- bb's EM55aj84ta

Yep, been using one of those for years! I have a Sinclair Labs unit that provides 100dB rejection outside of the 2 Meter band.
