All of you who know me know that the AT-1 is my favorite Heathkit. I have owned through the years, 25 +or- one or two. My first station was an AT-1, AR-2 (receiver), a J-38 (I bought it from Heathkit) and a knife switch to switch the dipole from transmit to receive. It was February 5, 1957, I was 15 years old. I got home from school at about 4:10 got the mail and there it was my license. KNØIMJ. Everything was ready and I was on 15 meters in 10 minutes. I called CQ and on the very first try I got a reply from a station in Trenton NJ. I WAS A HAM! Short of marring my wonderful wife (of 50 years now) and having our 6 children, this was the most important event in my life.
So is it any wonder that the AT-1, and the AR-2 is very important to me?
THE HEATHKIT AT-1
The AT-1 is a 30 watt input, crystal controlled, CW transmitter. Contrary to some books the tube line-up was a 6AG7 oscillator, and a 6L6 final amplifier with a 5U4 rectifier. I have owned and repaired 0ver 25 of these gems and I have never seen or heard of one with a 6AG6 oscillator. I worked all states and 25 or 30 countries with my first AT-1. It was very easy to operate, just peak the grid and dip the plate. The average output I have recorded is about 17 watts. I converted my first aT-1 to a 6146 thinking I was upping my signal strength but I never seem to notice that it made any difference from the 6L6. What a beautiful transmitter, with the gray cabinet and two-toned gray front panel.
