Fw: Response to my request of information about EduSat fromGAUSS team in Rome: Re: [CubeSat] Edusat operative or failure
by i8cvs 01 Sep '11

Hi Giulio, AB2VY Edusat is a "Non amateur satellite" ? ......OK ,but it has received an experimental license on 435.750 MHz for communicating at no cost into the "Satellite Amateur Frequencies" without coordination from IARU..OK ? It is very strange that Edusat has received an experimental licence for communications into the Satellite Amateur Band without a frequency coordination from IARU It is also very strange that the GAUSS group do not officially published the operating frequencies of Edusat stating that those frequencies published via internet are wrong frequencies. It seems that there is no coordination between our Communication Autority in Roma and IARU as well between the GAUSS group the IARU and the Radio Amateur community. In conclusion dear Giulio Edusat is a satellite not of our interest and please forget the above box for shoe. 73" de i8CVS Domenico ----- Original Message ----- > From: "Gi.

SatPC and TS-2000
by Carl Rimmer W8KRF 01 Sep '11

01 Sep '11

Is anyone using SatPC32 with a Kenwood TS-2000? If so, what is your Doppler.SQF entry for the transponder. I can not seem to get it to go into Duplex (Satellite) mode. It goes into Split and, of course, I can not hear the downlink. 73 -- *Carl W8KRF*

Has the ARISSat-1 CW-2 frequency shifted?
by Ronald G. Parsons 31 Aug '11

31 Aug '11

A couple days ago, I noticed that to get a 500 Hz signal for CW-2 (nominally 145.9190 MHz) to decode the BPSK-1000 signal, I had to change the unDoppler-shifted frequency on my USB receiver from 145.918500 MHz to 145.918280 MHz, a change of 220 Hz. This new value have been consistent over a couple days of careful watching. I don’t believe it to be an error in the keps or clock as it has been true both at the beginning and end of the pass. My receiver has been on for over a month, so unless a component changed value suddenly, .... Has ARISSat-1 changed, has my radio changed, or does only my hairdresser know for sure? Ron W5RKN

Hi all .. I am receiving the CW and TLM ok signal wise .. I tune in the CW to the mark in the CW / BPSK window.. But I don't ever receive any telemetry .. Using USB, FT897D .. I use the rig and computer for BPSK31 all the time .. Any ideas or suggestions ?? I even watched the You tube Video that was posted .. It seems like I am doing it correctly .. but must be missing something .. Thanks.. Randy - N2CUA

The FM telemetry downlink was initially acquired at 0014 UTC with the end of the SSTV transmission. The signal was barely audible. Transmission resumed at 0016 with S9+ strength, no noise, and the following details: - ID - Greeting in English - Secret word - MET = 45 minutes - IHU temp. = +31 degrees C - Control panel temp. = +31 degrees C - Battery voltage = 35.70 V - Battery current = -24 mA The CW beacon was not heard. 73s Bernhard VA6BMJ @ DO33FL

ARISSat-1 CW and BPSK-1000 telemetry heard over Vietnam
by Vu Trong Thu 31 Aug '11

31 Aug '11

Hello everyone, This morning I had a good pass of ARISSat-1 over Hanoi, Vietnam and decoded its BPSK-1000 for the first time. According to ARISSatTLM, more than 30 frames were sent to the server out of more than 60 decoded. Manually tuning the CW signal to keep it within range is fun and it was audible until the satellite was 1.5 degree under the horizon. Maybe next time I'll try the transponder :) 73, Thu XV9AA

Re: Good ARISSat-1 reception with rubber ducky in Eastern Canada
by Clint Bradford 31 Aug '11

>> ... using my F6A with stock rubber ducky ... Oh, Burns - think of the conversations you would start if you reached into your duffle and whipped out a tape measure beam - and started to un-furl the elements for all to gawk ... (No - I did not take such on our cruise ... But I sure THOUGHT of it ... (grin)) Although ugly, Kenwood put a lot of money into that tri-band antenna that comes with the TH-F6a. It is one of the better multi-band stock ducks. GREAT JOB! Clint Bradford, K6LCS
