[Elecraft] Back to the SSB board

[Paul - VE1DY]

Hi Ian,

When I first plugged in my ssb option, I lost all receive too
(extremely weak).  I checked all the things mentioned in the manual,
and then I checked the things mentioned on the reflector, all to no
avail.

Next I decided to to check for unwanted paths to ground, referring to
the schematic.

Between the P2 header connector pin 1 and c1, I found (with dmm) an
unwanted path to ground.  Everything looked fine, but when I pried up
the black plastic on the header, between pins 1 and 2, I found a
microscopic sized hair of solder, taking pin 1 to ground.

It's not always visable, but as Don says, check the soldering (hi).

Good luck with the troubleshooting,

Paul  -ve1dy-
