[TenTec] New Orion

[joel hallas]

Brad,

I can't comment on the first two problems, but haven't observed them.

On the last point, both receivers are of comparable sensitivity, and 
have a low enough noise floor to be able to hear the same signals. The 
real difference will be when there are strong signals close by. You 
could simulate that if you have a signal generator, or a seperate 
transmitter VFO that you can inject into the receiver, say 2 kHz away 
from the weak signal. Crank it up until the MP has problems and then 
switch to the Orion with the 1 kHz roofing filter and I think that you 
will hear a difference. If you have two sources and can separate them at 
2 and 4 kHz, you can do a near-in 3OIMD test and should really see a 
difference.

Even an S-38 can hear if there's no one else around!

GL and enjoy in the next contest or pile-up!

>Hello to the group.  I have been playing with my new Orion for a few days now.  I have a couple of concerns which I would like to throw out to the group.

I have tuned in to several very weak signals (in the noise floor) and have gone from an AGC of med, to fast to prog and can hear absolutely no difference.  Am I missing something?  Or is it just so subtle that you can't tell the difference?
