Hi Joe and all,
I doubt if the Arrow diplexer has 20dB of loss. If it did, we'd never
receive a signal! :)
I believe somebody here on the -bb will be performing a test on the Arrow
diplexer using a vector/network analyzer. It will be interesting to say the
least. There were preliminary
AMEN!
Finally someone on this board, that also remembers what the big knob on
the face of the radio is used for.
Maybe it's a age thing of when you got into the hobby? Like when I got

Not Hard
Just Skill,
Just like my other post about operating as a Novice in the days of only
crystal control. You did not operate full duplex on 40 meters, yet we
operated contests on one transmit freq and listened to the whole band
for someone calling us.
We all have just gotten incredibly

I've had my battles with desense. Originally I was going in the direction that
the RX antenna was in the envelope of the TX. It made sense and some elmers
suggested it. Even at low power (5-10W) and separating antennas by 30 ft it
would still de-sense, but not as pronounced (omnidirectional
I haven't used AO-7 for some time (need to revise my antennas to do so again).
But, back in the goode olde dayes (when the satellite first went into orbit)
we didn't have any problems with Doppler. The accepted method was to leave the
transmit frequency alone and keep one hand on the receiver
Hi Bruce and all,
No problem. Actually, I wouldn't call it research as much as curiosity.
Maybe the research will come later when developing something better. :) I
know the antenna works but can it be made to perform better? The antenna
itself is of great quality and workmanship, it's the
What is the best guess on the object numbers on the last two group of cube

Am not sure why I cant..
I have an FT-897D, 13 element 2 meter yagi and a 11 element 432 yagi.
I can also effectively use the 2 meter yagi on 432.. Matches well
And have used it on repeaters up to 60
Folks,
I think you are focusing only on transmitting loss and have
overlooked the impact that loss has on noise figure. If your HT has
a low NF (doubtful) adding 3-dB loss in Rx will raise the NF 3-dB
higher. The actual loss of sensitivity could be more than that.
Filter's size determines

Hello All,
I'm a bit confused over RS-38 or RS-28. I heard the CW beacon on
435.265 as found by Mike Rupprecht, but did not decode it at the time.
Are we looking at two different satellites?
A previous report suggested 435.365 and Andy Thomas' report had 435.440
and 435.490. Would these be
