Eric, I just read your review on Eham and feel that after owning the Orion for just two days, you really don't know what is going on yet with the rig. You state that you have discovered many bugs, some that went away and were only there once. I wonder if you have done a master reset yet, this will take care of a lot of problems you may be experiencing. One ham I know does a master reset every week of so to be sure all is in order. I would also talk with your distributor about some of the issues and see if they can help you resolve them.

It is true there is a minor problem with the sweep when the rig is in sub-receive mode. Of course, there is no sweep at all for the sub-receive, but when in sub-receive and you push NR or AN the sweep may freeze on the main receive. This problem is known about and hopefully being worked on by TT.

My point is that I believe if you will take the time to get help with some of the things you don't understand that do not seem to be working right, you will be able to really find out what is a problem and what is operator error. Toby W4CAK

2. Meter and AGC :
------------------

It seems that the meter needle is electronically controled by the AGC
system... well, in the case of a static discharge at the antenna, a "POP" is
heard thru the speaker, the needle is peaking at +20dB or +40dB and the AGC
is killed during half a second or so making the reception of the signal
impossible during this short amount of time !

I never have this "problem" with my FT-1000, the AGC was not killed by the
static discharge and I could still hear the audio behind it !


Is there a way to avoid that phenomenon ? The PROG AGC values cannot be set
to resolve this...


Orion's AGC works pretty well and your experience is
probably caused by specific AGC settings at the time.

For high QRN conditions you may consider reducing
AGC hold time to 0, and increasing AGC Decay (actually recovery)
rate to 20-50 dB/s.
