Small world is right Bill.

Tripoli in the summer was a blast literally; heat and sand. Right on the Med 
coast but no relief fom the 120-125F since it all blew out of the desert. At 
sea you could feel it way offshore.

I will say that all the natives I met were very friendly. They went down 
hill fast just as the USA is doing by letting the garbage float to the 
top.....

>> The KWM-2 (or 2A) found use in regular military nets. I was stationed at
>> Navcommsta Greece late 60s, and there were two KWM-2. One was on a

>> traffic between comm stations.  No S line stuff except in the Ham/MARS
>> shack, and there only a 75S-3C. Shack transmitter was a TMC FRT-70.
