> Range K Not sure of freq... RU-17

Range K is 9050 to 13575 kHz.  Coil navy type CW-47075.

All of the RU-* coils that you listed will work with the 1934 RU-3 and later RU receivers, plus the RAJ.  They will NOT work with ANY SCR-A*-183/283 receiver, FWIW.

> Kenwood TS-430S with hand mic, power cord and manual copies.

Most prospective buyers of a TS-430S will want you to remove the top cover and report:

1.  What crystal filters are installed, including bandwidth?  From one to four may be installed, and they are very clearly marked on top.
2.  Is the FM-430 FM-mode board installed?  If it is not there will be an empty area on the right top PCB area where it is obvious that some PCB should be.

The KY-65/ARA-26 is the emergency automatic Morse keyer that was used with the USAF AN/ARC-21, AN/ARC-65, and AN/ARC-58 high power aircraft HF sets.  It sends S O S (...  ---  ... instead of the technically proper ...---...) followed by the specific aircraft identification code as programmed by breaking away the appropriate spokes on the plastic programming wheel.

It's important to accurately identify these.  The connectors used on the ATA and SCR-274-N equivalents are completely incompatible with those of the MD-7/ARC-5.
