New photos and videos in Gallery

I have just uploaded a few new photos to the photo gallery on this site. The new photos show the new REV D nanoKeyer board which will have status LEDs added on board….(Green = Power, Red = PTT and Blue = CW Keying). REV D now uses a self supporting speedpot so that there is no visible hex nut on the outside of the enclosure anymore. Also the 6.3mm Stereo Jack was moved backwards and is now installed without external hex nut. These modifications give the final keyer when built into an enclosure a much more professional appearance.

I’ve built the new PCB into a prototype aluminum enclosure (same type as my REV C prototype, but with 10mm lower height) and the front and back face plates were professionally produced by a CNC milling company (very expensive, but hey its a “show off” prototype…).

I also added a few more YouTube videos below the gallery.

The REV D boards and their full documentation will soon be made available.

All REV B and C builders can have a look to the REV D schematics and easily retrofit this simple status LEDs extension externally on their REV B/C boards without any problems, since it is a pretty simple circuit.

nanoKeyer now SO2R compatible…

The open source firmware powering the nanoKeyer was just released by Goody K3NG in a new version. The new version implements some additional features only available in K1EL Winkeyer 2 protocol.

Thanks to this the nanoKeyer can now be used as a single keyer to key two radios via a contest logging application supporting SO2R (Single Operator 2 Radios) mode. SO2R operation was tested with two radios and the N1MM contestlogger succsessfully.

The Radio 1 is then keyed via the standard keying output and the Radio 2 is keyed via the PTT output.

The K3NG firmware code now has definitions for multiple CW keying lines.  They’re set up the same way as PTT lines in the code and are freely configurable and combinable. The unit can operated without any PTT lines activated.

As usual you can find a preconfigured firmware file for the nanoKeyer fetures here in the Download section.
You will find a single radio port version and a dual radio port configuration (for SO2R).

Thanks once again to Goody K3NG and his outstanding efforts and for this excellent piece of keyer code freeware.

Some builder country statistics…

Hello dear fellows, the nanoKeyer is gaining more and more popularity. So far the Parts and PCB kits have been shipped to builders in the following countries:

• USA
• Canada
• Germany
• UK
• Netherlands
• Australia
• Finland
• Switzerland
• Italy
• Slovenia
• Poland
• Romania

I hope that the list will even grow further in the future…

Builders should feel free to send me photos of your finished project and I am happy to add them to the nanoKeyer photo gallery.

Good luck to all the builders and I hope you enjoy the nanoKeyer as much as I do.
