[Milsurplus] Mackay nameplated Hammarlund receiver ?

[mstangelo at comcast.net]

I worked for ITT World Communications. I toured WSL Southampton receiving station before it closed down. They used that SP-600 Northern Radio oscillator combination as the receiver for their last point-to-point HF circuit, a diplomatic circuit for Cuba from the UN to Havana. See attached picture. ITT wanted to shut the station and sell the valuable real estate but the Cubans did not want to migrate to a cable or satellite circuit and ITT had to support the circuit. I heard that WLO took over that circuit.

> I have an SP-600 that was used by Mackay for teleprinter traffic in the 1950s-60s at its Southampton, NY receiving station (WSL). It was modified by Northern Radio. The mods consisted of removing the crystal HFO, outboarding both the VFO and the BFO, altering the 1st converter, and modifying the audio stages.
