No, the radio was on and plugged into the out-door aerial. This is the final test, since a "dummy load" on the test equipment represents an artificial
"aerial", and radio's sometimes act a bit spurious when connected to a genuine aerial. It was on a private companies "link" system, not a "repeater"
as such. The companies office radio was on UHF - 450 to 470 meg simplex, and the vehicle radio's were on mid-band 66 to 88 meg simplex. The "link" was
the UHF radio back-to-back with the VHF on a mountain top, so the office radio spoke only to the mountain, which then "relayed" the signal on mid-band
out to the vehicles. Not being a "repeater", I did not expect to be able to trigger a repeater tail, and being 3 AM, the business was closed, so I
couldn't do a live test with anyone. The mobile unit I had repaired was simplex 66 to 88 meg - I don't remember the exact frequency, but I think it
was around 73 or 74 meg. It was only a 25 watt unit, just an ordinary mobile, nothing super powerful or weird.
It was as if there was a "parrot repeater", a simplex system which records the transmission, then immediately plays it back, but this was crystal
clear, and came in about 5 minutes after I had stopped transmitting and put down the mike. The radio was still on, with the squelch set normally, and
so was dead quiet, unless it recieved a signal. Truly frightening!
Best I can describe it would be like you looking in the mirror to comb your hair, then wandering off to put some toast on, and as you come back past
the mirror, there you are in it brushing your hair! That sort of fright it gave me!
