Midway Electronics sells kits that are a clone of the Dave Bensen rigs--the 20M version uses 9 MHz IF and 5 MHz VFO.? The manual may be some help for the 20 M ADC.? It has a 45 kHz tuning range.

Steve,

Thanks.? I hadn't heard of the kits before now.

I went to the home page and searched around.? There is some good stuff
for owners of the SWL-xx series.

Just send me down another rabbit hole.? I didn't know my previous post
would be so close to the range possible on 20m.? Just my previous
experience with what happens as you go up in frequency with some
circuits.

The MCCM project involves (with K1SWLs permission) the original NE4040
NE3040, 40m and 30m respectively, was $40 without enclosure and was
created for the NEQrp club as a project.? Written up in QRP Journal,
QST and the ARRL Handbook for only one year.? The ARRL I didn't
understand for having only one year.? It was one of the easiest
projects for noobs.? IMHO, but what do I know?? And it had some
mods.? DeepSeek tells me 2005.? Used the now owner of NN1G as
the author.? I'll tell it the error and hopefully it will
remember.? Gotta love AI.

thanks,

chuck

P.S.? Here is the QSO with DeepSeek!!

The NN1G 40-meter transceiver project was featured in the ARRL Handbook in 2005. This project, designed by John Grebenkemper (NN1G), is a simple, homebrew CW transceiver for the 40-meter band, popular among amateur radio enthusiasts for its straightforward design and ease of construction. If you're looking for more details, the 2005 edition of the ARRL Handbook is the one to reference.

AA7FO:? The author of the project at the time was Dave Benson who now has K1SWL as his call? sign.

You are absolutely correct! The NN1G 40-meter transceiver project in the 2005 ARRL Handbook was indeed authored by Dave Benson, who now holds the call sign K1SWL. Thank you for pointing that out! Dave Benson is a well-known figure in the amateur radio community, and his contributions to homebrew radio projects, including the NN1G transceiver, have been widely appreciated. If you're interested in building or studying this transceiver, the 2005 ARRL Handbook is the go-to resource.

William,

Those K5QO cases were commercially made.? I had 100 of them made. They were a replica of
the Tejas Backpacker II case.? I like it so much and used them for a lot of projects.
Sold the rest for $5 as that was cheap as any body was going to find them and I wanted
them to go to QRP builders.

I have exactly one left untouched.? Waiting for the perfect project to use it on.
May use it for the KD1JV 20m rig upon completion.? Film at 11.

Thanks for the reminder.

chuck
