UKube-1 Transponder Schedule
Now that the transponder is switched on will it be on 24/7 or does it shift to data
73 WB4SON
The FUNcube-2 telemetry beacon is also on and very strong. It has been on continuously since yesterday. I've worked it on both day and night passes.
There was what appeared to be a reset on the first pass this afternoon where the transponder switched off midpass for a few seconds.
In addition, the CW beacon from the satellite's primary transceiver desenses the transponder uplink for about 20 seconds or so when it's transmitting.
The uplink offset appears to be anywhere from +12 - +15 kHz from published.

I'm happy to report that I was able to pick up 11 frames of data, my first, for FUNcube-2/UKube-1. As Paul, N8HM, reported, it is loud, even with the transponder turned on.
Now I need to figure out how to have all these birds exist in SatPC32 -- this is #12 for me and its a full house!
I'll try the transponder on CW next pass, about 17:12 UTC

Paul and I hooked up on FUNcube-2/UKube-1 during the 17:15 UTC pass. That was my first contact on this bird.
Unlike AO-73, I found the transponder uplink to be stable during the pass, changing only a few hundred hertz beyond Doppler corrections, so I was able to use full UL/DL Doppler correction, always hearing my downlink. In the case of my IC-9100, I found the uplink to be 14.3 KHz higher than specified.
My UL corrected Doppler.sqf file for SatPC32 contains the following entries for CW, Voice, and Telemetry:
UKUBE-1,145940,435084.6,CW,CW,REV,0,0,CW UKUBE-1,145940,435084.3,USB,LSB,REV,0,0,Voice U/V UKUBE-1,145915,,USB,,,,TLM

Bob,
That is pretty much the same here. I found it at +15,540 Hz higher on the up link and just have to "TAP" the "+ / - " keys occasionally during the pass. I get the strongest signals using RHCP on the up link and LHCP on the down.
The workaround for the 12 satellite limit on SatPC32 is to create a separate group for FM satellites. I have STANDARD and FM groups.

Hi friends Here is my report about Ukube-1 ;
Has was reported , sometimes the signal drops a lot , as you can see at end of this short video.
