I intend to filter it and amplify to ~20W for omni-directional antenna this season. Hope my job schedule will allow me to do that. Preliminary frequencies are 50.0665 / 50.0670 MHz FSK or 50.0665 MHz CW.

My First AVR Project
Finally tested my new AVR-programmer on programming DDS for 50MHz beacon (per OK1DX design here). Easy work with AVR Studio 5.1 (free download).
The DDS is based on a module with AD9850 that I have obtained on eBay for very reasonable price.

New AVR Programmer
I have bought my first AVR programmer - always used Microchip processors before.
This comes from DIGIKEY, Part Number is ATAVRISP2-ND. Very affordable price!
Furthermore, downloaded AVR Studio 5.1 (free) from ATMEL. Works even with Windows7-64bit!

Microwave misc.
Following pictures were on my "af4jf.com" web site when Microsoft announced discontinuing their web-hosting service. These pictures weren't enough for dedicated Page on this Blog, so I am adding them here to preserve them.
