Skipp, I'm just grasping at straws. The IMTS is a lot more complex than a simple duplex system that might have been used internally by AGT rather than by subscribers. Back in the late 60's, I used a half-duplex GE Pacer (!) radio in an MTS system for a couple of years after IMTS became available. It would have been better to use a full-duplex radio, but this is what I had at the time. The Pacer was an all-tube radio, except for the transistorized power supply. It had a mechanical decoder made by Secode. To make a call, I had to key the handset for a few seconds, and wait for the mobile operator to respond. That was not much more sophisticated than a magneto telephone! I eventually got kicked off the system because there were only a handful of people using the manual MTS- everyone was scrambling to get on the IMTS bandwagon. Ah, yes... Those were the good old days!

Would the Alberta Gov Telephones system be something like an IMTS (system) operation? Cute to think Motorola came out with something later than the Pulsar for IMTS... or was there a UHF/VHF Privacy Plus IMTS Phone? skipp > "Eric Lemmon" <[EMAIL PROTECTED]> wrote: > I suspect that your full-duplex radio was used in a mobile > telephone system by Alberta Government Telephones (AGT), > which later changed its name to TELUS.
