[TenTec] Tested: 1.8 filter definitely not engaging, ideas?

[Chester]

Tim....

	If you have, say, a 500Hz 6.3MHz filter, temporarily put it in
the 1.8kc slot and punch the 1.8kc button. If you can tell the 500Hz
filter is working, you will know the filter selection circuitry is
working. If the filter selection circuitry is working, then you can be
pretty sure the filter is defective. 

	If you can prove the filter is not working right, before you
send it to TT, try resoldering all of the connection points on the
bottom of the filter board, and try it again. If you just reheat the
solder connections quickly, you well not damage anything on that small
board and will more than likely 'fix' the filter.

	If you can determine the filter selection circuitry is OK, then
worst case, you will only have to return the filter.

	Good luck!

Hi folks -
Regarding my 1.8 filter that does not work, I tried Ron's test, below,
with
the PBT at 4 o'clock and found no difference. Then I opened the rig and
pulled the filter out of the slot while the radio was operating and the
1.8
selection button was on - there was no difference in reception. Having
had
an Omni V, I know what the 1.8 should sound like and it's definitely not
working. The jumpers that folks mentioned relate to the 9 MHz board and
also
to the Corsair II - but not to the Omni VI 6MHz board. So I am stumped.
Any
suggestions? Do you think the fellows at Ten Tec could work this one out
over the phone? Any help would be appreciated! Thanks for all of the
replies
sent. I sure do like this rig - don't want to have to send it to Ten Tec
and
be without it though!
Regards, Tim NZ7C
