Hi ib , OZ1MY

I have received the OZ7IGY beacon to day via FO-29 from 15:32
to 15:36 UTC when the elevation from the JO55 beacon site and FO-29
was ranging from about 30° to 20° during orbit 52360

The CW signal on 435.808 MHz slowly decreasing for doppler during
the ascending orbit going to LOS for me was about 10 dB over my noise
floor and it was transmitting the call letter OZ7IGY at a low speed of
about 30 wpm followed by a steady carrier with no QSB on my 10 turns
helix RHCP and low noise GaFet preamplifier normally used for satellite

Not yet heard OZ7IGY operating and calling CQ nor on CW or SSB
