OK Tim,
Don't get too down in the dumps over this.
First of all, AO-51 is a LOT weaker than UO-14 was.
AO-27 has the consistently best signal strength of the current FM
birds. It stays on for 6 minutes each pass, plenty of time to
work somebody.
Second, there are folks that are working AO-51 and SO-50
with HT's and rubber ducks and whips, but I'll bet they aren't
hearing all that well. I have some experience on that, and
a rubber duck is the last resort and you're lucky to ever hear
much.
There have been MANY stations who can't hear the birds that
come on with a big signal and call CQ during the entire pass and
never hear anybody coming back to them. I can safely say that
there is not one pass where there aren't several stations talking or
making quickie QSO's. You can hear the background noise
coming from some of these stations speakers in the background
when they're calling CQ and they are not hearing a thing, including
not hearing themselves calling CQ. I presume they think they are
all alone and wondering where everybody else is.
(Everybody else is calling them!). They need a preamp or a much
better antenna. It takes a lot of aluminum to get that 18 or 20 dB
of gain from a little preamp.
You'd probably be better off listening with a quarter-wave ground
plane than the 5/8 wave. The 5/8 wave has a pretty low radiation
angle. I've tried several different antennas on my MOBILE rig and
the quarter wave works better than many of the "gain" antennas for
doing satellite work.
Get a GaAsfet preamp, you'll get a GREAT improvement in the received
signal. I have an ARR preamp in the car and can actually hear AO51
and SO-51 fairly well. I can hear AO-27 even better. Sometimes I
actually get a little S-meter reading.
Your IC-706 with it's 25 watts or so on 2 meters should be more than
plenty to make contacts on any of the FM birds. Don't forget to turn on
the 67 Hz P.L.
I hope this is helpful. Good luck!
73,
John, K6YK
