Following up on our recent MFJ post<\/a>, SWLing Post<\/em> contributor, Ron, writes:<\/p>\n

Another thing about MFJ is they still offer the MFJ-8100<\/a> as a kit or built. This is the only regenerative receiver available as far as I know.<\/p>\n

Mr. Jue and his guys did a couple of tweaks like limiting band coverage to insure stability, using 1\/8 inch 3.5mm stereo phone jacks and use an LM386 audio IC to drive headphones or speaker.<\/p>\n

The whole thing is in a metal enclosure to minimize hand capacitance found in most regens.<\/p>\n

The QRP crowd likes to use the 8100 with flea power CW rigs, it’s that good.<\/p>\n

And it’s been in production far longer than the Heathkit GR-81 or any of the Knight Kit regens, too.<\/p><\/blockquote>\n

Thank you for sharing that, Ron! I had completely forgotten about this little kit when someone recently asked about the availability of Ten-Tec regen receiver kits (that are, sadly, no longer on the market to my knowledge)! I might have to grab one of these kits–looks like a fun one to build.<\/p>\n

By the way, I also believe the NM0S Ozark Patrol regen kit<\/a> is still available from the Four State QRP Group. Click here to check out the product page<\/a>. It doesn’t have a metal enclosure like the MFJ, but it’s also a fun kit to build.<\/p>\n","protected":false},"excerpt":{"rendered":"
