without tuning my Orion's (565 both) show SWR of about 1.2 into the T8 log
on several bands. tuning with the internal tuner can bring the SWR to 1.1 to
1 on a couple bands.

Subject: [TenTec] Orion 1 SWR
Wondering if anyone has run across an Orion 1 with SWR that remains at 1.7,
even running into a 50 Ohm dummy load. The problem appears to be on the CPU
board, not on the filter board or IF board.
In TUNE Mode (25W):
V_Fwd = 1.2V
V_Ref = .14V
I can ground the V_Reflected line prior to going into the CPU board (assures
ref power is zero) and the SWR remains at 1.7
If I ground the V_Ref line at the A to D converter, the SWR goes to 1.0
I've done a lot of checking and so far can't seem to determine where that
.14V is coming from. Ideas appreciated.
Thanks,
Jeff W4DD
