Voltage Requirements of ICOM IC-910H
by DeYoung James 22 Jan '07

22 Jan '07

Greetings, I also use an Astron SS-30M. I run two rigs with it, a 910H and a 706. Mine is six years old now. The meters are worth the extra few bucks so you can see the voltages and amps being pulled. Mine is currently at 13.8V and 2A in receive mode with the 706 off. The only maintenance I have done, once or twice in its lifetime, is to use pressurized air to blow any dust out to prevent any potential shorts or arcs. My 910H manual gives a power requirement of 13.8V DC +/-15%, negative ground. There are many reasons to supply the nominal value so it is probably a good idea to feed it 13.8V with a power supply that can supply suffient current! I wouldn't even think of using anything but the spec considering the amount of money that has gone into my 910H!

Voltage Requirements of ICOM IC-910H
by Joe Leikhim 22 Jan '07

I wouldn't risk it. Look at the Astron SS-30M as a suitable replacement. It was rated lowest noise in a QST line up test some years back. I have two, they are small, lightweight well regulated and have Volt and Amp meters so you can see whats going on. The SS-30 is same unit w/o metering. Message: 1 Date: Sat, 20 Jan 2007 12:25:28 -0800 From: "Michael Hatzakis Jr MD" <lists(a)hatzakis.net> Subject: [amsat-bb] Voltage Requirements of ICOM IC-910H To: <amsat-bb(a)amsat.org> Message-ID: <20070120202539.71KKPdz00E98z(a)mailbox5.ucsd.edu> Content-Type: text/plain; charset="us-ascii" I am changing my supply for my ICOM IC-910H because my PS-30 is dying. I have an SGC PS-50 supply that is not regulated, per se, it is a huge supply with massive transformers. It appears to work fine, but I am worried about the fact that is starts at 16v or so. Specifically, is 15.5 to 16v too high to safely run this radio and is a drop of 1-1.5 volts too much unregulation for proper operation?

Pehuensat-1 heard in LU
by lu7abf 21 Jan '07

21 Jan '07

Elusive Pehuensat signal for us, at least was copied in Buenos Aires, Argentina. On 01/21/07 at 21:48 LU (GMT-3) Pehuensat-1 was heard on 145.825. Weak but clear signal just above noise by ear, unable to decode ax25. Signal copied at night on northbound pass when satellite almost was leaving coverage for us on north coast of Brazil. Using FT-736 & omni super turnstile antenna for 2 meters. Captured wav with mixW can be heard and possible decoded with some dsp magic on http://www.amsat.org.ar/lu7abf.wav . 73, lu7abf, Pedro lu7abf(a)amsat.org.ar www.amsat.org.ar

GO-32 Upload Troubles
by Bruce Semple 21 Jan '07

21 Jan '07

Is there any available guidance / hints & tips / things to check ... about uploading files to GO-32. I can seem to request files without any problem .. I get the OK WA3SWJ and then the ...xxxx file heard message -- and I do get files downloaded. However I cannot seem to consistently upload files -- I get the as far as seeing *** INCOMING CONNECT from 4XTECH-12 ... I even get a file number assigned --- bet then after a few seconds I get a disconnect with frames sent/received 1/1 Bytes sent/recvd 0/0 REJs sent/rcvd: 0/0 T1 timeouts: 0 I have been able to upload about 4 files -- but not with any consistency -- I have not been able to correlate it to high or low elevation passes -- does not seem to matter. Is that expected behavior that you request an upload -- first your WISP software logs into the bird -- then the bird's BBS initiates a connection to your station? Any ideas / suggestions would be appreciated. Thanks, Bruce WA3SWJ

by Paul Reilly 21 Jan '07

21 Jan '07

Hello, I am a beginner in packet radio, and am looking for recommendations for a good 2m radio with built in TNC. I have heard good things about the kenwood TM-D700 dual bander. But this radio is no longer listed on kenwood's site. Has it been discontinued? Anyone else got any recommendations on a good 2m radio for doing packet work to the satellites? Thanks Paul
