[UK-CONTEST] FT1kmp partially dead

[G4FNL]

John

I have had an intermittent problem with my FT1000MP, which I have fixed.

I traced it to one of the 2nd / 3rd IF filters that "plugs in" to the board
(on the underside).  The fault would typically affect TX and RX -
intermittently. In my case, it only affected CW transmission / reception. It
might be something simple like this that's causing you problems?

I fixed it by cleaning the lugs (connectors) involved on the specific filter
and also making the filter have an 'interference fit' by slightly bending
lugs.

Hopefully, it's a simple fix.

Hello,
I'm looking for an expert who can point me towards the most likely reason
for my FT1kmp to stop working on 30 and 20m, both on receive and transmit,
whilst continuing to work on the other bands.
My guess is one of the relays that switch the bandpass filters, but you may
be able to save me the whole fault-finding thing, either by saying 'Yes,
that's what was wrong with mine.' or 'No, mine was the xxx.'
Thanks for reading.
