Hi Joe,
I meant packet cluster, FM networks were in use for decades. I recall
guys at YU4EXA were used to announce DX frequencies in Japanese numerals
(ichi, ni, san, etc) to prevent hijacking spots by local rivals at
YU4FRS who SWL-ed YU4EXA FM channel regularly.
Another funny anecdote from my YU1EXY days. As our FM network frequency
we used 145 200 (if I recall correctly). One day YU1EW called his
brother home and told him "Call YU1** at 145 200 and ask him to call me
at work." Two hours later, Zoky called his brother again "Did you call
YU1** ?".
"I called several times, phone rung but nobody answered." (In those
days, 6 digit phone numbers were in use in Yugoslavia). :-D
