The Scout Regen

Last weekend, At the Hamfester’s Hamfest in Peotone, IL, I picked up a little Scout Regen kit from a fellow ham. The gentleman I bought it from was just lamenting to a friend “Nobody builds anything any more…,” but when I walked up to check out the un-built kit, he added, “….except this guy!”

It was unbuilt, but the metal frontpanel already had its decals applied (or perhaps pre-printed?), which was a nice place to start. I don’t have a great track record when it comes to applying decals and labels.

The overall build took about 2 hours. The Scout Regen Builder’s Manual from the QRPKits website is very thorough, and was easy to follow. The only issue I ran into was a missing 5pF cap for the detector section. I substituted two 10 pF NP0 caps from my stock, soldering them in series before installing them in the PCB. Additionally, after completing the first part of the detector section (basically, everything installed but the coil and the power switch) the current drain had jumped to 20 mA. After finishing the build, the current dropped back to under 10 mA. How odd.

Listening with this kit is a lot of fun. Regen control is smooth, but very narrow; I may replace the regeneration control knob with a larger one. There’s all kinds of interesting things in the span of the receiver. Shortwave stations, the 80m and 40m hand bands, I found a couple different “WLO” beacons… really nifty. It’ll be nice to put on in the background while working on future projects.

Hear you on the Air!
