Re: Linear Xpndr Operating Economics & more again
Whoops!
I forgot to mention that the antennas were an omni vertical ground plane on 2 meters for the uplink and tri-band beam for the 10 meter downlink.

Boy, that sounds familiar ! My first Oscar station was a Regency HR-2B FM rig with ONE crystal in the middle of the uplink band on 2 meters, keying the high-low power switch. You couldn't hear the low power but the 15 watts on high power made it fine.
And the receivers were an HW-101 and Hallicrafters SX-117. Bought an AMECO preamp for HF, which helped out on 10 meters.
That was good enough to work lots of stations, maybe a total of 600 QSO's on OScar 6 and 7!
Then when the RS-10, 11 came along, I tried some mobile work using an ICOM 230, again only one frequency, keying the PTT line, no chirp, and Yaesu FT-301 for receiver. Larson 2 meter antenna and Hustler 10 meter antenna on the pickup. Worked quite a few QSO's that way, too!
All CW only, of course on mode A. Didn't get an all-mode rig until about 1986 during the "RS" era.

My first Oscar Station,,,
I do not remember if it was Oscar 6 or 7, but it was 1975, and we
listened to many passes on the ten meter downlink.
We got from a local ham, an old AM vfo controlled 2 meter rig.
It
was AM only. it had a Red face and was BIG like the size of a heathkit
SB-200 amp. two VFO's one for transmit and a separate one for receive.
anyway we connected out Hallicrafters TO Keyer to the PTT line of
the mic, (with no mic installed) and it worked amazingly well. That
was out Oscar station back then, we made like 25 states or so on that
setup,

Simple answer...FM rigs will tend to "chirp" as you key the mic
line as
the VCO pulls onto frequency...crystal matrix FM radios such as
the old
Standard will be T-9...
The purists will cry about the chirpy signal...but, most people
who work
CW on satellites would relish a new operator/contact even if
they
were QLF.
That being said...I have works scores of stations with my own
"chirpy"
signal and even have received some polite 599's back.

Let's not forget about the funcube dongle as a terrific

no? Assuming someone already has a vhf/uhf rig, I can see
getting
qrv on linear
transponders today for under $200. Or am I being too simplistic?
