Most of our correspondents did not like the idea of me trying to convert my Heath HW-101 into a BITX-101. But, thinking that I still might to this, I decided to take the old rig off the shelf and see what it looked like. I liked the looks of it -- lots of space, simple circuitry, nice belts and gears for turning the many variable capacitors, no black box ICs. I could see traces of my earlier repair adventures -- electrolytic caps that had been replaced, the plastic dial clutch that I'd "fabricated" myself. Then I decided to try to fire it up. Hey, the receiver sounded very good. Next thing you know, I was getting the transmitter going. Then I was working DX on 20. By the end of the afternoon, I knew there was no way I would be tearing this old rig apart. There is simply too much soul in this old machine.

I have some resources for parts if you're looking to get it ship-shape.
ReplyDeleteLooks like Ralphs Electronics is now out of the Amphenol mic connectors (cord-mount and panel-mount), but part numbers are there.

i have mine in storage somewhere in Deepest Texas (safer than Deepest Queens, I suppose). Anyway, the belts are all corroded. I would love to bring it down to GDL. NOT the "poor man's Collins": just a Heathkit. But, as you say, they have the personal imprint, or soul. BTW watsa about the CAnadian astronaut who played guitar on the ISS?
ReplyDeleteI've got a similar Heathkit trx tucked away. It doesn't work. You've convinced me to get it out and get it going. I was going to gut it and create a new trx using the box and the controls, but no more...
ReplyDeleteThanks Mike, but I think I'll stick to the mic jack mod.
ReplyDeletegxg: That Canadian can sing! And guitar!
Dominic: FB OM. Another Heathkit saved!
I built my HW-101 from the kit back in the late 1970s. I sold it when I went into the Navy. The guy I sold it to contacted me a few years ago and said I could have it back if I paid shipping. So I did. I have been restoring it ever since. Repainted, new tubes, new dial, new reduction drive. Also handmade a main tuning knob out of a solid block of aluminum that looks stock. I just kept green part of an old knob. The added weight makes it tune very smoothly. Also working on a HQ-120 receiver. Old rubber turns into concrete.
