[UK-CONTEST] FT1000MP MKV front end gone - help!

[Alex GM3ZBE]

HI,
I did a bit more checking.
The rx doesn't work on any band plus the attenuator position makes no 
difference.  Switching IPO in and out causes a change in noise level, so 
looks like the pre-amp is ok.  looks like the discontinuity is between 
the output of the pre-amp and the input to the rest of the rx? 
(switching diodes?)

Thanks for all the info.
