Larry,

Who's selling those?  I checked Arrow, Jameco, Digikey and Mouser.  No joy.

Jim,

Look at TE Connectivity (Schrack) RT31C0xx which has the same footprint
with bifurcated contacts.  This will fix the intermittent RX issues.  I
have a web page with the datasheet at

I have a later version of this amp that uses two Schrack sealed T/R relays
(1 - RTD14012F SPDT 16A and 1 - RTE24012F DPDT 8A both 12VDC) for
antenna switching mounted on a small board.

The manual shows the earlier version with the open frame 3PDT relay.

I use this amp occasionally and has had the problem of intermittent receive.
The relays have already been replaced once to solve the problem but it
has returned.

Does anyone have a mod or suggestion on how to solve this issue?

I have considered the W7RY QSK mod but I don't use QSK.

Thanks in advance.
