REQ:Spare part for Kenwood R-1000 Communication receiver.
 

Greetings All,
Just got my receiver back from Kenwood Australia saying that
T3 is defective & no spare are available. For those without a service
manual, T3 is a tuning coil, part of a filter circuit 42.055-43.055Mhz
(T1-T4 the same part number L32-0198-05 ). Apart from removing the
coil & trying to repair, any othe options available.

Thanks
Don

Rewind the sucker if you can't find a substitute.

Well, a scrap R-1000 will have four of them. ;-)

If it's screwing things up now, you could probably just jumper over that
one section of the filter (C18, C19, T3) and retune.

It's a 1 MHz wide stagger tuned bandpass filter in the synthesizer.
It's probably not that critical, it's used to clean up after the mix of
the VFO and the second xtal controlled LO. (I had to tweek that part
of mine when it wouldn't lock on the higher MHz. A 100 MHz scope on the
provided test point to get the levels even across the range of the VFO).

Or figure out what resonates at 42.5 MHz with a 22 pF capacitor and
get that range of sub-mini adjustable inductor.
