[TenTec] no voltage to 1.8 filter?

[Chester]

Hi Ed...thanks for the feedback. I see you mis-read Tim's email the same
as I did. Tim said he had NO voltage at connector 41 on the PBT board. I
missed that statement when I read his email. And even if one of his
PIN's were open, there is still a DC path to ground via R22.

See your from Marietta!! I'm retiring and moving to my home town of
Valdosta at the end of this month. Cant seem to find much HF activity in
that part of GA? (Yet!!)

Not necessarily Tom... one or both of Tim's OMNI VI  PIN diode(s) 
associated with that filter could be bad, and it would still act as you 
describe. If the levels associated with the other PIN diodes when 
selected-and when NOT selected-are the same as those for the non-working

filters' PIN diodes, then the PIN diode(s) should be the cause-as an
OPEN.
