Subject: [amsat-bb] Couple of 736r questions..
I had a few questions about the operation of the Yaesu 736r.
1: I am on one of the SSB satellites (440/2 meters) - I hear my signal
coming back down and all seems fine. Shortly afterward the RX and TX
frequencies are not in sync so I need to adjust one of them to find and hear
myself again. Which is best to adjust RX or TX?
There is rule of thumb but I think it is not good idea. Try this - During
transmitting - set SAT swith to TX pos. and try tune VFO to hear your
downlink signal readable (continuos tuning), during receiving set SAT swith
to RX pos. and follow correspondent frequency and when you will transmit
again to correspondent set SAT swith to TX pos. and quickly tune VFO to find
your signal. I made a lot of QSOs that way using FT736R and set of two
diffrent radios (2m/70cm).
FT736R has no special knob to Doppler correction (like TS 2000 has) and
without CAT Doppler correction you will have to use SAT swith many times ...
2: In trying to make life easier by using the Memories Recall (MR) on the
unit. I put in the frequencies of the centerband of each of the satellites.
It is easiest to quickly adjust my frequency by just selecting Memory Recall
1, 2, 3, etc. That works fine for the FM satellites, but I am locked into
that frequency on the SSB birds and I cannot use the VFO to adjust +/- my
frequencies. If I hit VFO I go back to the frequency I was using before I
did the Memory Recall. Is there a way to use the Sat Memories yet have the
VFO work when you get there without changing the Memory contents as you
would if you used the VFO/M button? Any tricks?
YES - in memory mode push FUNC button and then VFO button, it will transfer
memory SAT frequences to VFO (SAT VFO) without affect content of memory that
can be recalled by pressing MR button. It also works in regular simplex
Thanks for your time.
