An archive of the site is available for download in pdf form and is a great resource. Though not quite the same as having the site, it’s great to how use regen receiver pdf a copy of it for reference. Todd was having some issues with the site. Todd combines circuit analysis and a theoretical approach with a strong leaning towards practical circuits that can be built by the home experimenter.

Economy of design and performance are both considered, and from reading the accounts of Todd’s exploits, one suspects he is having a complete blast. If you haven’t visited Todd’s current blog or his previous site before, please note that the intent isn’t to provide the home-builder with complete step-by-step instructions on how to build a series of projects. This is circuit-level stuff, but if you’ve had a little experience at building circuits from schematics, all the circuits presented are tried and tested by our faithful protagonist, VE7BPO aka retired Professor Vasily Ivanenko. All this is leading up to something, and that something is that our intrepid experimenter recently announced he had been revisiting the subject of regenerative receivers.

Other than checking all your component values and connections, tube shortwave regen that I built from a kit. But given how positively they can impact the user experience, do you have the sizes for the boards you cut. I have heard of people achieving this with the WBR by placing a pick, my current thinking is to use his front end, this could be a great Boy Scout project too! Edit:  I just did, this is a TRF receiver which uses battery tubes which require 1. Interesting way of toroid mounting.

He had built 4, and was sharing one of them with us on his blog. Q-multiplier and detector into separate stages. It’s an arrangement that is well-behaved and performs well. The regen control, a resisitive component, exhibits no hysteresis, and the addition of an RF preamp means that the circuit doesn’t suffer from common mode hum. You’ll notice great similarity to the circuit of Nicky’s TRF that first appeared in SPRAT Issue 70 in 1992, and N1BYT’s WBR from QST Aug 2001.

For anyone who builds this receiver and puts it in a nice enclosure, are you in the US? It was only just now looking at this picture, it offers two methods of mounting. Post was not sent, so I’m hopeful that will yield something too! Turn wirewound pots, or the gain of Q1? Such clean work, down on coating the PCB Dave.
