[TenTec] ORION_ANT_SELECTION

[Mike Gorniak]

Hi George,

I don't know what to say about the volume control situation, but I have 
observed the same behavior as you regarding the
receiver antenna selection situation. As always, an antenna driving 2 
separate loads simultaneously will deliver less voltage into each one of 
them than when driving either one alone.

However, I've yet to find a situation where this compromised the ability of 
the Orion to hear a signal.

I've observed this behavior in all versions of the software that I have 
gone through, going all the way back to 1.340.

Orion owners.
I have noticed a problem with my Orion running on the latest firmware, 
1.372. I never had the previous version as it was loaded at the factory.
When I switch the sub receiver to ant 2, that's where my beam is connected, 
I notice a slight decrease of signal on the main receiver??? Is it the 
loading of the sub receiver on the main receiver doing this. Is this normal?
I also get blasted out of my shack with the audio volume reverting to full 
volume. I madly reach for the off button as my ears are near bleeding from 
the blast! This happens, as I can remember, when I turn up the volume. 
Turning it back on relieves this annoyance. This is a very infrequent affair.
The other small annoyances I can live with, so far.
