Chances are it's the first coil to ground in the bandpass filter...if it's 
the bandpass filter.  Does sensitivity come back at the next range higher?
I dont remember if the older 1000 (vs MP) has input LP/HP filtering at 
all, but the same coil tends to go bad in those as well.

I never had a problem with my D, but I've replaced several of these little 
coils in my MP's.  I've not had any fail since I put RX limiters on them.

I've never had any problems other than those first coils to ground in the 
filter sections.

73, Ty K3MM

Hi all
I recently discovered my FT1000D has gone low gain above 12Mhz - by
around 12dBs or so. Probably the results of being a mult rig during a
recent contest ! It is fine (by comparing with another FT1K) up to that
frequency. Presumably a component in the bandpass switching has gone -
any ideas which may be the culprit ?
