[amsat-bb] Question from Newbie

Sun May 13 11:34:47 UTC 2018

Uli,

You change frequencies on all of the satellites, for the FM satellites it
is on the 70cm band. On SO-50 you adjust the receiver, AO-85, 91 & 92 the
transmitter is adjusted.

It took me a while to get used to changing the transmitter during a pass,
since it is not as noticeable as it is on the receiver; more so since I
listen at more than I transmit.

Not sure if you caught this on another thread on the BB:

Hello,

I've set on memories for Yaesu FT-897 and Baofeng UV-5R for FM Sats:

SATID Downlin Up-link STone

SO50E 436.802 145.847 77.4 (Corrected STone)
SO501 436.802 145.847 67.0
SO502 436.794 145.850 67.0
SO503 436.786 145.853 67.0

AO851 145.980 435.180 67.0
AO852 145.977 435.172 67.0
AO853 145.974 435.164 67.0

AO911 145.964 435.242 67.0
AO912 145.961 435.250 67.0
AO913 145.858 435.258 67.0

AO921 145.883 435.342 67.0
AO922 145.880 435.350 67.0
AO923 145.877 435.358 67.0

Using http://amsat.org.ar/pass to see when the satellite will show, using
xxx1 for AOS, xxx2 for TCA and xxx3 for LOS.

So far success on contacts, hope is useful.
