NA5N "Pipsqueak" regen receiver: tour through the bands

This is my version of NA5N's "Pipsqueak" regen. My first homebrewed radio and a lot of fun to build. And it works!
Here's NA5N's original article on the build: www.ncqrpp.org/files/qrpp_vol...
And here is WB3GCK's modification: www.qsl.net/wb3gck/pipsqk.htm
Mine tunes between 2-12 MHz (but I only had a 360+ pF cap, used 4 and 12 turns).

I built this same radio years ago

Both Paul harden and chuck kitchen are legendary, nice work my friend

This is really cool. If WWIII goes down, we may have to rely on McGuyver approaches like this.

Thanks for posting this video. This design is definitely a candidate for my next radio project.

Very well done. Cool to listen w/ your knowledge of the different frequencies, effects, etc.

Try a small variable capacitor (say 5-10pf) paralleled with the main tuning capacitor. Also try backing off the rf gain control. This sometimes helps to “fine tune” the regeneration or provide a better mix on strong sub signals. Nice build and good sounding little rig. 73’s GW8PNE.

Thanks for keeping us updated on your latest creations. You're an inspiration!

My advice is to start gathering kits of parts for future builds.. You'll never find everything you need all at once anyway, so be patient as you compile a list and start looking around hamfests and eBay. You also spread out the expense over time that way. Also, if you have a hard time finding high enough value of tuning caps, consider switching in fixed value parallel connected mica caps and use a smaller value of the variable caps. You get finer tuning that way as well.

Nothing ugly about that my friend, also who doesn't love a proper old school capacitor, M0KJZ

Pipsqueaks are young and insignificant by definition

"Don't want to end with Brother Stair" ... Brother Stair is the end of all things ... and now speaks to us, over the air, from beyond the grave!

That receiver can demodulate a.m. only. To be able to receive side band you'd need a side band demodulator. That's why those voices sound garbled.

Skipping over Alex Jones?
