RADIOHF - FS SquareSdr 2: I have a Square Sdr 2 Transceiver for sale. I purchased this a couple weeks ago and used it about 3 times (maybe hour of use total). Unfortunately I have bills to pay so have to sell it. Asking what I paid which is $590. Shipping and Insurance on me. This is one of the first 12 made. He only made 100 of them and they sell out within a minute when he sells them a batch at a time. So this is your chance to avoid the 2 week+ wait. Also, when you purchase from SquareSdr all you get is the radio itself. I will include a power cord and sma-239 connector. Will do PayPal or Money Order. I will give my phone # to call me. I have done a bunch of transactions here and also can be found on 3.892 after 10pm.

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.
