Tim is right about regens and other simple receivers: they are certainly fun. They also teach some subtle principles of the radio art that are missed by folks who limit their experiences to more complicated approaches. The regen listener has an active role, always touching up a control to dig the weak ones out. The experiments continue with headphones and antenna connected. I wouldn't choose a regen to operate during a contest weekend--but using one as part of a simple station to work all states would be an interesting exercise for a skillful and patient radioman. Have fun, Rick KK7B

I haven't used a regen since 1964 when I had a Heathkit lunchbox 6 meter rig. I guess that gives away my age. Hi :-) I'll try several different approaches before I finally settle on one. I may still setttle

The Heathkit VHF lunchboxes use a Superregen, which is a mutation of the basic regen circuit and quite a different animal. Superregen receivers are still commmon in garage door openers and radio-controlled toys. I have used them too, but my memories of them are less fond, hi. There are many receiver architectures, and I highly recommend exploring a number of different ones. Each has unique attributes, and sometimes brick-wall limitations that may not apply in a particular application. A simple receiver will often outperform a more complicated one when dedicated to a single band and mode. Best Regards, Rick KK7B

Regens ARE a lot of fun. I recently built the Scout Regen from Hendricks QRPKits. For the uninitiated, it's an easy build and a fairly inexpensive introducti

For those that want to start with a working circuit in order to build from scratch, here is the link to Paul's web page and down the page is the reference. > > http://www.aoc.nrao.edu/~pharden/hobby/Hobby.shtml > Now is the time to start building before the winter season sets in and the QRN dies down in the northern hemisphere. My first kit that I built as a teenager in West Texas was a Bandspanner from Knightkit and I spent many an hour listening to the AM Broadcast bands looking for the "X" and found some good blues and rock & roll stations across the country. Those were the days..... :-) I don't think my memory has decayed enough to forget the mfgr and name, but then again ... FYI chuck, k7qo

I just finished building the TenTec 9-band regen receiver. It's a great kit, and the radio works very well. It's not much good as a communications receiver (too hard to tune SSB) but it pulls in the world AM shortwave stations really well. It willl be a lot better when (if) we ever get out of the bottom of the sunspot hole. John AC0CX

Here is a link to most of the Ten Tec manuals, or so they claim. http://www.mods.dk/manual.php?brand=ten-tec Here is a link I found for the build and the schematic of the TT1253 reg receiver. http://frrl.wordpress.com/2008/08/03/history-of-reciever-design-regeneration-and-building-the-tectec-1253/ Hope this helps, although not directly related to the material in EMRFD. chuck
