Help with Yaesu FT-736R fault
by Ron Taylor 13 Aug '11

13 Aug '11

Hi Folks, Hoping someone may have some ideas on a fault that has just developed in my FT-736R radio. The multi function S-meter has decided to quit on me. It does not indicate in either receive, transmit, diiscriminator/ALC or any other position of the meter selector switch. The radio though, still functions perfectly on both transmit and receive - with no indication of any degradation in sensitivity or transmit output power. I will be pulling it to bits, but thought I'd first check to see whether anyone has come across this particular fault. The radio was bought new in the '90's and I have fixed one fault in the power supply about 10 years ago. Many thanks for reading this. 73, Ron Taylor - VK6TF Perth, Australia.

Dear All, Below are telemetry from ARISSat-1, 13 Aug 1057 UTC. Satelite was in high power mode then switched to low power mode: MET - 60 Min IHU Temp - +40C Control Panel Temp - +48C Battery Voltage - 35.77v Battery Current - -8mA (discharging) This was also the first time using the FCD to copy ARISSat-1. I will try to replay and send the BPSK telemetry later on. 73, Sion, 9M2CQC

ARISSat Telemetry 03:33
by N0JY 13 Aug '11

13 Aug '11

I copied and forwarded 6 telemetry frames and copied 4 Kursk frames completing a set, between 13/03:31 and 13/03:33. After the satellite went into eclipse I did not hear it again for the rest of the pass, approximately 7 more minutes.

ARISSat 0116 UTC 13th August
by Colin Hurst 12 Aug '11

Reasonably confident pass was on for full pass on HIGH POWER. 7 Degree pass passing behind an 80 foot gum tree. Managed 16 frames until beam went through 180 degrees, which is good considering copy with other sats is not good behind that gum tree. Copied continuously till the beam started to rotated. LOS was at end of rotation 73 Colin VK5HI
