[TenTec] Omni VII SWR

[Greg S]

Mike- I should think a slightly higher voltage as you listed would be fine, as current drops with a rise in supply VDC. It is well within specs. I would be sure no ancillary equipment (Other than Mic and/or key and dummy load) are plugged in, and see if the situation changes. I would also measure that supply voltage with a meter (Scope to look for excessive ripple would be better) at the rig. (In-line fuses/fuse holders have been known to cause these  type of erratics lately on other equipment..... be sure to eliminate them as a cause.)  If problem persists with rig in free air, I am out of ideas for now. Please report back to the list as you have time.

 hmmm. The Alinco DM-340MV analog 12 power suppy might have
 been bumped up to
 slightly over 14v on its adjustment knob. i've lowered that
 to 12v and kept
 a small fan blowing over the unit and it seems ok right now
 after a 2 hr
 test. Makes sense. At this point don't know if it needs the
 extra fan
 blowing from the back or the lowered input voltage, or
 both.
 
 Kinda stupid, I know.
