Okay guys Thanks. Some how I thought the linear transponder was on days on the weekend. I did hear the data transmission, said to say, I did not know how to tune it on my PSK 31 program. It was very stong. Think it is SSB. One day I will get it right! Thanks all. R W4BUE

Download the FUNcube Dashboard to decode the telemetry. It is a SSB transmission. http://funcube.org.uk/working-documents/funcube-telemetry-dashboard/ At times, the control ops in the UK may command the linear transponder on for daytime passes on the weekends, but they have not done that yet.

Ok. Yes Sorry was typing my phone. Yes I was talking about SSB. I have an HF all mode, but don't have 2 meter or 70 cm on that radio. I have a couple FM baofengs HT's. So guess I use them for SO-50. Ive been doing some reading and thinking of getting a USB dongle. Ive been reading on the funcube

Hi Peter. Thanks for your mail. The transponder has been on every day When and where are you listening? When: During eclipse, so a night time pass. You should have 3 passes, usually around 7pm to 11pm local time. Where: 145.950 to 145.970USB / CW for additional info, please have a look

The satellite is only in transponder mode when it is in eclipse.. In full sunlight it is in beacon mode only. Just curious about the overall design goals of this operating mode? Putting solar energy into and then taking it out of batteries suffers about a 30% loss in efficiency. All else being

From Graham earlier in November on the BB: Hi All, Yes in telemetry (also known as educational) mode we have around 300mW and this is a much higher average RF output than when in amateur (also known as transponder) mode. Total current drain is therefore greater

Hi Peter. The satellite is only in transponder mode when it is in eclipse, with the beacon on low power. In full sunlight it is in beacon mode only. 73 Dave, G4DPZ FUNcube Team Member On 27 Dec 2013 04:55, Peter Budnik kb1...@comcast.net wrote: Dear Felloe Satellite Hams I've been
