[amsat-bb] Increasing Icom 910H deviation on 9600 setting?
Dear AMSAT, Has anyone successfully increased the maximum FM deviation of the 910H when using the 9600 setting on the radio? We have not been able to. We have two units, and one is maxed at 2.5 KHz and the other at 3.2 KHz deviation. We've used the service manual to adjust the deviation to max higher values (>7KHz). But, this doesn't affect the 9600 input path. Looking through the service manual, on page 10-1 lower left corner, it shows that the gain control we just set doesn't affect the 9600 path. So, I'm thinking of modifying the over modulation detection circuitry to allow for a larger peak to peak voltage signal to be input. The components that see that voltage appear to be able to handle it. Has anyone tried this, or know of another way to increase the deviation? 73, --James ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Re: Finally managed an Arrisat-1 real time telemetry decode!
Hello Burns, Very good on your reception in New Hampshire. I was calling W4HTB and W8RVH who were trying to find me with my receiver fixed on 145.930 for the 20:16Z pass over Cincinnati. I was able to hear my downlink for about a minute before ARISSat-1/RADIOSKAF-V reached Max El then lost it for a while as my Tx antenna had no El control. I picked it up near the end of the pass and heard fairly strong CW near my Rx freq. From the variation I observe I believe the satellite is in a slight tumble as the 145.930 MHz reception goes very weak then builds, sometimes rapidly.. I was fortunate to get an SSTV picture through the transponder on Nov 12 when by chance I managed to get lined up with the short antenna on the 70 cm receiver to transmit an R36 picture.. I may try SSTV again if signals warrant. I hope others will keep trying CW, voice or SSTV. I do observe that the signals seem to be stronger at the sats lower altitude.

A few minutes ago on the ARISSat-1 pass over New Hampshire (US) I received it nice and strong (as usual) got the doppler correction running on SDR-Radio (have done that before), and with a newly-built computer in my shack finally had enough processing power to deal with SDR-Radio, Virtual Audio Cable, AND the ARISSat telemetry decoder, so I got some actual real time telemetry. Just in time for the "last telemetry frame" contest, I'm afraid :-) Was anyone hitting the repeater around 20:20 UTC today? I was not listening, but watching on the waterfall display of SDR-Radio. The telemetry and the FM digitalker were very clear...not sure if there was anything in between...I saw a few smudges that might have been modulation... Burns, W2BFJ ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] ARISSAt-1 Decay prediction - G7HIA
Christmas Greetings My decay prediction for ARISSAT-1 is that she will be sub 200km altitude by Jan 4th. I am using a very different method from Nico, but have the same proviso, the prediction is valid only if the solar numbers stay at similar levels to the present. Wishing everyone on the bb a happy Christmas and a healthy and peaceful new year. 73 John G7HIA ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] FO-29 alive
FO-29 test operation at 23rd Dec was succeeded! JTA was on at 1422z. Lound CW telemetry was heard. Unfortunately, the telemetry was shut off by UVC at 1426z.
