Troubleshooting dead subRX after adding filter

[Pete Smith N4ZR]

I just finished installing an 8-pole 400 hz factory filter in the subRX
of my K3, and was congratulating myself on a straightforward and easy
process ... until I reinstalled and tried the subRX.  It is not
receiving anything at all - I can hear internally generated noise but
that is it.  There is no change in the sound or level of the band noise
when I switch between filters.

I've checked and rechecked the crystal filter setup, the TMP cables,
etc. Before I tear it open again, is there anywhere in particular I
should be looking?

Pete,

If all tmp cables are fitted right and the menu settings are OK, how
about the bottom-connectors to the K3 main-board?

Thanks, Arie. I found the problem. the TMP connector on the cable
running from J5 on the KREF3 board to J82 on the KRX3 had worked loose
at the J5 end, where I couldn't see it until I removed the sub-RX again
and the cable came away with it. All is well.
