Back in the early '50s, the French Foreign Legion was fighting in what
was then known as Indo-China. They had a network or radio stations
that used calls starting with "TT(x)" Some I can recall a TTN,
TTA, and TTV but after all these years can no longer fit location to
callsign.

The net control station, at Saigon, used FLZ and I believe he
contacted about a dozen outstations - all on CW.

Does anyone have call sign books from that era that might help me fit
these calls to locations?

Any help welcome.

Thanks,

Sparky
