Re: Rethinking high power on FM sats
by Clint Bradford 07 Jun '21

07 Jun '21

>> … Since then I have often used 50 watts to ensure my signal gets in consistently even on sats that don't need it. That was horrible practice … >> … rovers … IMHO, “rovers” are no different than any other satellite operator - whether an experienced grid chaser or a ham trying this for their very first time. There should be no “rules” promoting roving over any others' attempts to work the satellites. Similar to the steroid controversy in Major League baseball: Should anyone have special rules to give them an edge over established regs? Clint Bradford K6LCS

Re: Amicalsat : 6 June S-band Transmission
by Julien NICOLAS 07 Jun '21

07 Jun '21

Hi Matthias, This is not AmicalSat, when did you recorded it ? There is two possibilities of failures. The first is bad attitude of the satellite when transmitting (not nadir, remember that the ADCS is not working, unfortunately), the second is a problem in the planed task (this is the first time we use a planned task for a S-band transmission, I will double check everything.) I will keep the list updated about the next session.

G-5400B and Fox Delta STS2 USB Interface
by Les Rayburn 07 Jun '21

07 Jun '21

Prepared a new DIN cable to run between the Fox Delta STS-2 USB satellite interface and my Yaesu G-5400B. Tinned all wires, and checked them for correct configuration with an ohm meter. With USB cable disconnected, I attempted to do the initial calibration. This failed. Immediately, when powering on the G-5400B, the rotor transits to full UP elevation with on control input. The STS-2 will control movement from left to right normally, but has no effect on elevation up or down. When the DIN cable is disconnected, manual control of the rotor with it’s front panel switches is normal. Removing the top panel cover on the STS-2 USB, I can see that LEFT, RIGHT, UP, DOWN LED’s light up as expected when control inputs are pushed. Judging from this, I assume the problem may lie inside the Yaesu G-5400B control box itself. Any ideas on next steps for troubleshooting or lacking that, can someone recommend a repair service for the G-5400B control box—even better one that could repair the G-5400B and verify proper operation of the STS-2 (assuming that I ship them both units.) Thanks again for all the help. Sorry to consume so much bandwidth on the list. 73, Les Rayburn, N1LF Maylene, AL EM63nf AMSAT #38965, ARRL Life Member, CVHS Life Member, SVHF Member Powered by Mailbutler <https://www.mailbutler.io/?utm_source=watermark&utm_medium=email&utm_campai…>, the email extension that does it all
