[Elecraft] Problems with KRX3A

[Gareth M5KVK]

Hi there
I bought a s/h K3S a couple of years ago (SN 10901). It has a KRX3A installed, but I’ve never tried to use it until now. When I enabled the sub receiver this morning, I found I was getting no signal.

I’ve checked various CONFIG settings and it’s set to use the MAIN ANT and it’s AF is independent of the K3S. In an attempt to make progress, I reviewed the installation instructions.

Item 4, after enabling TECH MD, is Tap DISP and rotate VFO B to display SYN1 and SYN2. I do not see these items. Any idea how to debug this?
