I still have two Inrad #22 narrow filters for the Kenwood
TS-850, 930, 940, 950 series radios. This filter goes up
front in the 8.8 MHz I.F., thereby protecting the third
mixer and subsequent stages. Inrad advertises the bandwidth
as 250 Hz, but the 6 dB BW is actually 368 Hz, perfect for
RTTY. The filter curve is shown here:

I'm asking $65 for each filter, including shipping via
Priority Mail. If you Paypal me today, you should have the
filter in time for the RTTY Roundup. Please email me
directly.
Happy holidays!
