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.

ANTETUNE - Homebrew 150 Watt Antenna Tuner For Sale: Homebrew 150 Watt Antenna Tuner For Sale:
-
This antenna tuner is a homebrew unit
that appears to be well made.
Very heavy duty.
-
It has a roller inductor that is fairly
heavy duty. But the capacitors are regular
receiving capacitors, limiting its power
handling capabilities. If you have a normal
100 Watt exciter, there is no problem. If
you use a linear amplifier, this tuner is
not for you.
-
The tuner has adjustments on the front for
the two capacitors, and for the roller
inductor. It also has a switch that permits
switching capacitors in to the circuit.
The back has a switch to bypass the tuner,
plus SO-239 connectors, in and out.
-
Buy this tuner for $50 plus shipping from
Florida.
