An introduction to Heathkit single banders, Part 1

The only videos about these great rigs. THank you very much. I encourage you to do a couple more about it. Thanks de KK4NWW

I had a couple of these. The output power would fade after the finals heated up. I did a couple things. Neutralized the finals, and moved the bypass caps that got hot to the other side of the circuit board. Now power was max when plate current dipped, and didn't fade away when heated up. I had a mobile PS and swapped the transistors out for ones that had lower saturated switching voltage drop. Plate voltage went up and power as well. I could get much more power out and on SSB wasn't a horible amount of heat. The receiver used to come back out of transmit with a loud rush... which I also fixed. Can't remember what I did exactly, but think I used a diode in the circuit. Great little rig. I should have never sold it. I coined the phrase "Greefkit" back in the day. I worked for Heathkin for a year in 1968. - WA6QVI

Was that a kiss at the end? I love you too like my old HW-12 I built myself at 12. 1966

Hi Tim. Thanks for your Video. I have an HW22 myself I got from an estate sale. I started at the PSU and will re-work the radio soon after the HP-23A. I looking forward to your part 2 as I could not find it in the lineup. Good talk thanks hope to be on air with my rig soon. 73 Phillip ZS6PVT

What is an HW-22?

Beautiful little rig.

Man, HF rigs have REALLY come down in price, especially for the technology you get in a rig today. Still, I often have the most fun with the simple QRP kits for under 100 bucks....or of course the vintage gear out there that can be had for a fraction of its cost when new. Heathkit sure had a good run. Real, practical radios you built yourself. I have a set of the Heathkit Twins on right now - HR-1680 and HX-1681. My IC-7200 is a great performer - but the Heathkits are sometimes more fun to run! Thanks for showing us your HF monobander!
