Following up on my own posting, I received some of these little buggers and am able to load executables into the device easily modify the message.

I can also easily put the whole works into low power (like uA level) mode between transmissions. I can alternate messages. I'm working on putting the whole system (computer + beacon transmitter) into a deep sleep if battery voltage drops below a preset level while the solar panel fills the battery up. It will be pretty easy to only transmit at night if it's on a band where there's no daytime prop.

There's a ton of options for less than 3 bucks delivered. 

I'm learning how to program (actually more modify and combine existing routines) the thing, but that's fun too.

go to bangood or ebay and look for Arduino Nano clones.

Damned if work doesn't really get in the way of good hobbies.

That is an absolutely beautiful radio. Congratulations. They work really well too!

Nice plans. Use a PVC boom and you've got a nice gain antenna for dirt cheap that will work every bit as well as the commercial version

Amen. I'd drop an anvil on them in a heartbeat.


I've been meaning to experiment with the Arduino I've had around for years. A couple of hours of dinking around and downloading libs and I've got a functional programmable keyer that I can set into "low power mode" (uA?) . Nice! The keying string is almost infinite in length if needed and given that it's programmable, it can be buried in loops in loops in loops giveing a variety of messages, etc. Cool!

Oh, the best part? Buying from or similar outfits, the mini versions of the arduino are less than three dollars DELIVERED in the US.  Yes, I'll have to hang a single transistor on the output to key a transmitter but that's not any sort of problem.

May they rise again before the fall DX season. They're always fun targets here in the US

I really enjoy reading (and seeing pix of) your stations.  Abandoned buildings with power are hard to find!

Very nicely done, and the modulation out of the rig is really nice. The audio sweep just about sent my cat into orbit.

You design nice boards, and your test bench is a work of art.

Still copyable  in SE.

Slow rep rate..... perhaps midwest based on beam heading?

No joy yet here on EC

Thanks for these posts Jim...! I wish I heard 10% of them from out here on the eastcoast

Weak but copyable on 6398.4   It's right on the noise floor but I can see it easily on ARGO and hear it on the QSB peaks.

C&P just appearing above the noise here tonight. Will check it a bit later. I can see it on Argo but only S0.01 copy as there's a carrier just at the high end of my pass band that I can't quite shift out with the IF.

Later...a bit later.

Good to hear some activity here on the eastern side of the US

Listening right now. Decent copy on the QSB psaks

I have one of those antennas. If it's high SWR on all bands, I'm guessing that it's a coax problem.

Swap the coax and let us know what the result is.  The outboard parts of the radiating element aren't even seen , say if you're operating on 10m, so if it's that high on ALL bands, it's probably the most simple reason...

Bad coax or coaxial connectors.

Disconnect the coax at the feedpoint and connect it to a dummy load and see what you read.
