- MISC - Variable Capacitor
- I saved this for a receiver project but want to clear out some space. I don’t recall what I pulled this out of, but it may have been from a National receiver. The capacitor fins are in good shape and they rotate freely. The rubber insulators that isolate the capacitor body from the base bracket are deteriorating but otherwise it’s in decent shape.
I had measured the capacitance of this a while back as 44-810 pf but can’t say how accurate that measure is.
Asking $15 with local pickup in Pevely MO or I’ll ship for the actual shipping costs.
I’m good on QRZ and have good reviews here. Thanks for looking.

- RADIOHF - Kenwood R-5000 general coverage receiver
- ****PENDING****
A nice example of this very popular HF receiver. 30khz-30mhz all modes. Factory AM filter, which I think sounds better for BCL than the optional YK-88A1, but YMMV. It does have the optional VS1, which speaks your frequency at the touch of a button. Seems to work fine; been in my stable for many years, but I'm not using it much.
$450 plus shipping from 37920. Most forms of payment are okay.

- MISC - Mechanical Filters for Collins 75A4 FS
Mechanical Filters for Collins 75A4
For Sale:
-
I have a pair of Collins mechanical
filters that were used in a Collins
75A4 receiver. They have been tested,
and both work well. These plug into
the 9 pin socket behind the front panel
of the 75A4. It is quite likely that
they can be used in other receivers as
well.
-
300 Hz filter for narrow CW
-
9000 Hz for AM
-
Each filter is $195. Buy both of them
for $375.
-
Prices do not include shipping from Florida.
-
Thanks. 73,
