The Heathkit AT-1 Amateur Radio Transmitter. Post #319.


It's time for a little nostalgia, thanks to the Heathkit AT-1 Amateur Radio Transmitter. Jeff Tranter does an excellent job of explaining how the AT-1 works and demonstrates some of its capabilities. This 3-tube transmitter, coupled with a simple dipole or vertical antenna, gave newly licensed novice operators many hours of enjoyable contacts. The rig was well-shielded and offered fairly good TVI suppression. Once a novice passed the General License Exam, he/she could plug in a VFO and an AM modulator. I've only used an AT-1 once in my 37-year amateur radio "career"-a rig belonging to a fellow amateur operator on Hawaii Island back in 1977. Even in that year, the AT-1 was well out of production, having been originally introduced around 1953. As Jeff warns all would-be restorers, special care must be taken around this rig, since high voltage may be present on the chassis. Tranter recommends removing the old 2-prong cord and replacing it with the 3-prong plug now used in most modern electrical equipment. You can find modification ideas on the internet. I'm still intrigued by just how well the AT-1 works, given its age. If you see one of these classic Heathkit rigs for sale, buy it and restore it to operating condition.
