Black Cat Systems’ 22 Meter Band Part 15 CW Beacon Kit

Many thanks to SWLing Post contributor, Robert Gulley (AK3Q), who notes that Black Cat Systems has developed a simple 22 meter beacon kit. The price is $20 shipped! A few details:

The kit includes the PCB and components, including a custom programmed microcontroller that will continuously transmit the ID / callsign of your choice, up to 8 characters, at about 13 wpm.

Small size – just 2 7/8 by 1 1/2 inches. Easy to build, just a few components, all through hole, no surface mount.

When ordering you note your callsign/ID to send and it will be pre-programmed.

Black Cat Systems has all kit details including full instructions on their website.

If you like the idea of building a beacon, you must also check out the beacon Dave (AA7EE) built recently–a true work of art!

Many thanks to SWLing Post contributor, Dave Richards (AA7EE),  who writes:

Thomas – I know you’ve posted before about the NBC chimes, so I thought you might be interested to know that CHRS, the California Historical Radio Society, has acquired one of 8 original NBC chime machines. They don’t think that more than a dozen were ever made. CHRS have their own building on the island of Alameda, CA, and are putting a huge amount of time and work into amassing an impressive collection of vintage radio gear. [I]f you scroll about 1/3 way down this page, you’ll see the news, along with a brief history of an NBC chime machine, and pictures of the one they now have in their collection. It is a rare find indeed!

Very cool! Thank you for sharing this, Dave! I’m very happy to hear that these chimes have proper custodians.

Dave builds an N6KR/Wilderness Radio SST from scratch

sst-aa7ee

Regular SWLing Post readers might recall the gorgeous Sproutie MKII regenerative receiver my buddy Dave Richards (AA7EE) built last year. No doubt, Dave does a proper job with his homebrew radios–a talented builder and engineer indeed!

Check out Dave’s latest homebrew project: A Scratch-Build of N6KR and Wilderness Radio’s SST for 20M.

Dave’s notes and images are so thorough, you could use his article as a reference to build your own! Fantastic job, Dave!

Dave Richards (AA7EE), has just published a brilliant post about his new beacon: the Sproutie SPT Beacon.

low power, legal beacon

Dave’s beacon is located on 13,558 kHz–he would love your reception reports. Dave notes in his post:

“If you hear the SPT beacon on 13,558 kHz, please send a report – either to the e-mail address listed on my QRZ account [look up call AA7EE], or as a comment underneath this post. Reception reports will be very eagerly received. One gentleman in Seminole County, FL, reported that the area around the SPT frequency was a cacophony of noise in his area, and he stood no chance of hearing it. Those kinds of reports are useful too.  If you put your own HiFER beacon  on the air, do introduce yourself on the LWCA message board, and John can include you on the list of known active HiFER beacons.

Readers: let’s give Dave some reception reports! Though I live on the opposite side of North America, I will certainly be listening!

Dave, thanks again for publishing such an informative and detailed post! You’ve inspired me to build my own beacon.

Dave unveils the Sproutie MK II regenerative receiver

SproutieMKII

My talented pal, Dave Richards, has built yet another home-brew regenerative receiver––which he dubs the Sproutie MK II––and wow, it’s a thing of beauty.

Dave tells me has been working on this receiver for many months, and upon viewing the following photos of it, it’s clear to see why he took his sweet time. As in his original Sproutie, a vintage HRO dial has taken pride of place as the centerpiece of his rig; it looks stunning.

But the Sproutie MK II is not only painstakingly-crafted on the outside; like Shaker furnishings, wrought for the eyes of God both outwardly and within, the interior of Dave’s receiver is equally well-crafted.

Okay, maybe that’s a little over the top…but if you doubt me, just join me in admiration of this board:

SproutieMKII-board

As for performance?  Of course, with such a clean interior, the Sproutie II performs like a champ.  Dave posted a few videos showing how his new receiver commands the airwaves and aptly handles AM, SSB, and CW.

That’s an amazing piece of kit you’ve created there, Dave!  Hats off to your incredible craftsmanship.

Check out Sproutie II on Dave’s blog, where you can read a full account of how he designed and built this gorgeous regen receiver.
