 RADIOHF - Yaesu XF-115C 500Hz CW Filter, 7 Pin PCB 
- I bought this 8 pin filter to modify and install in my FT-818, then ended up getting the stock 7 pin version. This filter is often marked or cross-referenced as a YF-122C or YF-115C depending on the specific plug-in board configuration. Key Specifications - Collins Mechanical Filter; 500 Hz bandwidth at -6 dB (2 kHz at -60 dB); 455 kHz Intermediate Frequency (IF).
YF-115C (Standard/Large Board): Uses an 8-pin connector. This version is listed for these desktop rigs: FT-847, FT-1000MP, FT-1000MP Mark V, FT-1000MP Mark V Field, FRG-100
YF-122C (Compact/Small Board): Uses a 7-pin connector. This version contains the same XF-115C filter but is designed for mobile/portable rigs: FT-817/818, FT-857, FT-897, FT-2000.
Buyer to confirm that this filter will work for their application.

- 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,

- RADIOHF - Collins S Line Complete Station
- Very nice and functional Collins S Line station:
32S-3 Transmitter, 75S-3B Receiver, 312-B4 Station Control (Speaker, Watt meter, phone patch),516-F2 power supply, 30S-1 Amplifier.
Receiver works like a champ, amplifier works great on old AND NEW radios (with inline T/R switch for modern rigs). The transmitter works, could use a little TLC, dial calibration is off. I always tune with the receivers dial and VFO. Full output power on CW 100 watts + but low transmitter output on SSB 20-40W depending on band. This leads me to believe I have a weak tube in the 32S-3 but a new set of military tubes are included. Station is in good cosmetic condition and I powered everything on before placing this ad.
I cannot ship this equipment. Prefer in person pickup so you can see what you are getting. A line equipment is not for sale. Contact good on QRZ
$2000 for complete S Line including 30s-1
$800 if you don’t want the 30s-1 amplifier (will not split up primary station)
$1500 for the 30s-1 alone
