We have a winner! The MFJ-8100K shortwave receiver kit giveaway

Congratulations to SWLing Post reader, Audrius Simkunas from Lithuania, who was chosen at random from the comments on our contest post!

Many thanks to the kind folks at MFJ Enterprises who donated this prize and shipping that is worth well over $100! There aren’t many manufacturers and retailers who would agree to ship anywhere in the world.

What a response!

We had 165 comments/entries at 16:00 UTC yesterday when the contest ended. At that time we had a random number generator pull the comment number which lead us to Audrius.

Not only is that an impressive number of comments, but I absolutely loved reading about your favorite kits. What an amazing radio nostalgia trip!

Let’s do this again…and soon

This was a lot of fun, so we’re going to do more of these giveaways. If you have any ideas about a theme, contact me. While I enjoy making more challenging contests from time to time, I also love posting contests that are accessible to everyone regardless of their radio experience.

Thanks again, MFJ! And congratulations, Audrius!

After posting Ron’s note about the MFK-8100K receiver kit, I touched base with MFJ and they have kindly donated a new 8100K kit to us for an SWLing Post giveaway. Thanks, MFJ!

This giveaway is open to anyone, anywhere. MFJ will ship it directly to you if there are no Covid-19 shipping restrictions to your country.

Here’s how to enter the giveaway…

Simply comment on this post and tell us about your favorite kit that you’ve built. This can be your first kit, your last kit, or anything in between. Don’t just give us a model name, tell us what made it a fun or special project.

If you’ve never built a kit, but are eager to do so, tell us why you would like to build the MFJ-8100K! Do you have a soldering iron?

We simply want to make sure a kit builder or want-to-be kit builder gets this prize! We’d even invite you to share a short post about building the MFJ-8100 (no obligation–only if you wish).

Details

We will pick a winner at random from the valid comments in this post on Wednesday, September 23, 2020 at 16:00 UTC.

This means you must enter a valid email address in the appropriate comments field (not within the comment text itself) so that we can contact you.

Of course, the SWLing Post doesn’t sell or share emails–never have, never will–this is only so we can contact you to obtain your shipping address if you win. Feel free to use a throw-away email address if you wish.

This is all about taking us on a great kit-building nostalgia trip, so have fun!

Many thanks again to MFJ Enterprises for sponsoring this contest!

Ron reminds us that MFJ still offers a shortwave radio kit

Following up on our recent MFJ post, SWLing Post contributor, Ron, writes:

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

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.

The whole thing is in a metal enclosure to minimize hand capacitance found in most regens.

The QRP crowd likes to use the 8100 with flea power CW rigs, it’s that good.

And it’s been in production far longer than the Heathkit GR-81 or any of the Knight Kit regens, too.

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.

By the way, I also believe the NM0S Ozark Patrol regen kit is still available from the Four State QRP Group. Click here to check out the product page. It doesn’t have a metal enclosure like the MFJ, but it’s also a fun kit to build.
