[amsat-bb] UKube-1 Transponder Schedule

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

73, Bob, WB4SON
