Hey Guys,

Just a suggestion . . . (might  work)

Here is my $5 suggestion to fix the problem.

Build yourself an external RF Attenuator with 3dB, 6dB, 12dB.  Cascade them
such that you can dial in 3, 6, 9, 12, 15, 18, 21, and 24dB.
Run RG-174 (the very thin stuff) from the input and output of this
attenuator, back into the Orion.
Insert this in the RX ANT line in series with the existing attenuator (I'm
assuming it has one; can't remember).

Now you have an easy to use, dedicated control and don't have to use the

Maybe my assumption that more signal attenuation will achieve the same thing
as reduced RF-Gain is wrong.
In that case never-mind, this was a bad idea.  But I think it will work.

Of course you could always buy an Eagle, which has an RF Gain control  ;-)

Hi to All,

        I'm adding my thanks to John Henry and Ten-Tec for Version 3 and the
new sub-receiver.  Great work and superior service.  Thank you!

        Personally the only thing I have greatly missed (and still do) is
the lack of a dedicated RF Gain Control.  In my exclusive CW operation, the
Multi Control is overworked. It causes me to make quite a few mistakes.
Reversing the type of function between the TF and AF Gain Controls would
suit me fine.  I haven't thought through how this would affect the
sub-receiver though.

        Besides that, the only other thing I can say is that I hope to live
long enough to get an ORION 3 that also has 6 meters on it.
