Hi, We had a problem with the server yesterday evening and it was only reported to me at 09:30 UTC today! The problem has been fixed and should not re-occur (we had not allocated enough memory to a process). If you see any problems with the server please email me directly at the above address. Thanks 73, Dave, G4DPZ FC Warehouse Developer

Controlling IC-910 With Gpredict 1.4
by B J 21 Apr '14

21 Apr '14

I recently installed Gpredict 1.4 on a machine running openSUSE 13.1, along with Hamlib 1.2.14. I can control my radio with that combination, except the radio switches between VFOs every time the software updates the output. That temporarily cuts out the audio, which would be rather annoying during a QSO. Is there anyone on the list who uses Gpredict 1.4 for their '910? If so, could you send me a private message? Please advise. Thanks. 73s Bernhard VA6BMJ @ DO33FL

Wanted: IQ recording of UO-11 pass
by Douglas Quagliana 21 Apr '14

21 Apr '14

Does anyone have a recording of a good UO-11 pass made with an SDR receiver? I'm looking for a recording that has I and Q channels (not just regular audio) and something that has most of a "good" pass. Douglas KA2UPW/5

Hi John, W0JAB On AO40 you should remember at least the spin fading due to the tumbling of AO40 i.e. the spin modulation...... ..........

Yaesu G-5500 Wiring
by David Rush 20 Apr '14

20 Apr '14

I've got a used set of Yaesu G-5500 az/el rotors, and the plugs that attach to the rotor housings. I need to build cables to connect them to the Yaesu controller. Page 3 of the instruction manual shows some info about the wiring, but doesn't explicitly say which screw terminal on the controller goes to which pin on the rotor plugs. Is it simply 1-1, 2-2, ... 6-6? David, ky7dr
