Thanks for this, very useful. I have a 530 and a 830, so useful. Thanks too for the link to the hybrid group. I was having difficulty finding it.

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.

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

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

You're stuck on using a Raspberry. Just use a tablet. That's what I use. Keeping it simple, right?...

Excellent job, thanks for the video. Subscribed.

Pipsqueaks are young and insignificant by definition

Skipping over Alex Jones? What were you thinking? Alex Jones is the best!!!

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.

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

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

I built this same radio years ago Thinking of building another Yours works great 73

"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! Nicely done. What is the "RF knob? RF Gain? I noticed you never twiddled it as you did with the regen control and, of course, the tuning knob. I've seen many, many truly antique broadcast receivers (c.1923, say) that had three knobs but have never played with one to see how it worked. I assume they were regen like this one.

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

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

How about a frg 7

This is so awesome! Would you post a link to the actual forum subject so I can find it and read through it please. I'm watching again to make sure I heard the correct capacitor I think it was 47 pf

Maybe one of these cheap chinese DDS on the vfo out and that will get you a way to see actual frequency and might even allow you to remotely steer the TRX fully too? Cool vid :)

Just did this on a 520 Sports Edition (SE). I went with the drain of Q4 on the IF board though, as suggested in the manual for the KW station monitor. I have a reg. 520 too, maybe I'll try what you did. Easier spot to get to. Itching to try out but waiting foe more parts. Did the main filter caps. Just ordered C... 15-16? Different part number on the regular 520. But new manufacture dual 22ufs.

Absolutely awesome! Thanks for the great explanation. Definitely want to try this.

Is that a tube transceiver? I want to buy a old tube TRX encase one day we get a big sun flare hit us or if some cold country tries to use EMP weapons or something like that. Yes! if this happened then a pan adapter for an SDR would be useless but I highly doubt those to scenarios will take place. So if I have a old tube TRX laying around I may as well put some mileage on her.

I think I found the problem: No one has ever told you "That Will Never Work!" Because, *as we all know* , home-brew stuff, especially antennas, that are designed and built by people who simply think things through *never* *work*. Glad you don't listen to those people. :-)

This is the true spirit of amateur radio. Time to head to the hardware store to pick up a painters pole and speaker wire! 73

I enjoyed the video. And I followed your instruction. Yes, it does work with my TS-520. Thanks a lot.

Sam - was that Kenwood hybrid page info from manual page or could you please post the link you found - thanks

Awesome work..! I have an old TS-830M and will look at doing something similar..

That is so cool! Well done!
