I have previously written about interference from FM stations on the HO-68 linear transponder. Now it appears the other satellites with linear transponders also suffer from local FM traffic by people who haven’t got a clue that they are transmitting in the satellite uplink segment of the 2 meter band.
It looks like AMSAT is going to launch a new satellite! ARISSat-1 – the successor of SuitSat-1 – is ready to be launched on Progress-41P heading to the International Space Station on Friday, January 28, 2011. It will be deployed into its own orbit during EVA 27 currently scheduled for February 16. Once in orbit, it will slowly decay and eventually burn up in the Earth’ atmosphere. SuitSat-1 decayed after 7 months in orbit and that’s also a likely life time for ARISSat-1.
So, why is ARISSat-1 cool and why should we care?
Wednesday, November 10, Pete MI3EPN reported that he heard what sounded like FM transmissions on the lower end of the HO-68 / XW-1 linear transponder and it didn’t sound like ham radio operators making contact over a satellite. It was an interesting coincidence because I could remember that I have seen some FM-like signals while I was recording HO-68 on Tuesday evening but I thought it was some local interference.
