Pastime Projects Regenerative Receiver Kit Redesign Coming

December 2, 2016

7.28.09 prod

The regenerative receiver kit is returning to the http://www.pastimeprojects.com catalogue of radio enthusiasts kits.
The design was redeveloped around the 40 meter ham band range. It receives AM foreign broadcast, cw, single side band with patience, and radio amateur AM stations. It is not recommended for use as a main receiver for radio amateur stations. Regen receivers tend to require careful tuning. They show more drift than commercial receivers.
But they are fun for beginners, short wave listeners, and experimenters. Our design now has been tested on the
3.5 MHz range, and 80 meter ham bands are being heard. The kit includes some unusual features. One is the use of
a “space charge” type tube that uses 12 volts on the plate as well as the filament. That means this receiver will be powered by your 12 volt DC power supply. The kit is somewhat difficult, but assembly, wiring,, and testing are explained in detail in the step by step manual that is included in the kit. Stay tuned for more! 73 Glenn for Pastime Projects (at) yahoo (dot) com.

Got an email from one of our customers wondering why we didn’t make the output on our 6V6/6L6
transmitter kit a pi-network instead of link output. Very good question! Probably one factor
in our decision was the cost of the change. Variable capacitors are expensive. The chassis size
would probably have to be larger also. But, these are not big issues. He is probably right; we
should revisit the pi-output design.
Some of the projects underway now include:
1. Regenerative receiver with tube(s) and toroid coils – Short Wave design with capability
to tune ham radio cw, am, and ssb in a rudimentary fashion. Status at this time is a prototype
6 – 10 MHz model that is very promising. Needs to be simplified for easy duplication as a kit.
Current model runs on 12 volts dc. No project completion date set.
2. Our low pass filter design converted to PCB configuration. We have the tools but not
the talent or time to complete this task. Interested in volunteering your expertise in this
very basic board design?
3. Vacuum Tube T-R switch based on vintage Handbook designs for handling our transmitter/
receiver interconnection automatically transferring from transmit to receive mode. Well underway
with this project.
4. Simple receiver design, probably solid state, to allow reception of cw along with our
transmitters..
