He was the second owner of this radio. This particular Collins radio is rarely seen for sale. Note:It has not been used since 2000. I found had to clean the pots. This radio was Peripherally tested for receive & transmit. Used a dummy load and watt meter. Power about 130 watts in CW mode. 20M USB with voice a bit over 100watts. Physical Condition: 8.5 out of 10 because of the chip on the Rt side of front fascia & some light cabinet scratches. The front face plate itself looks great. This Rockwell-Collins KWM-380 Pro-Mark, serial number 1238, is a solid state transceiver covering 160 – 10 meters on SSB and CW modes. I don’t know what filters or options are presently. I removed the internal shielded cover so you may be able to figure it out. This radio is in nice condition overall for its age, showing very little wear! We encourage you to look closely at the photos. Wired for 120 VAC. With the radio the AC power cord.. A keyboard, not sure what or how it’s used. {Pictured}No manual, PDF downloads available.
