Amateur radio.Making the world a smaller place. Link to my K2 build. Sunday, May 31, 2015. It's been just too long since my last post! The time sure has been flying here at VE3WDM! The board installed in the K3. June 1, 2015 at 6:26 PM. Will it bring a significant lower noise floor? Does it get rid of the rattling noise at 50MHz when dialling over the band? June 1, 2015 at 6:42 PM. The new board looks a lot simpler. I would buy it but 2 times 220$ is too much . June 2, 2015 at 4:29 PM. The KSYN3A extends...

My QRSS and SMT-Hell signals received by the PA9QV grabber on 40m. Building on my Arduino and AD9850 powered WSPR transmitter.

Jottings on Amateur Radio: August 2014
http://photohamrad.blogspot.com/2014_08_01_archive.html
Jottings on Amateur Radio. Monday, 18 August 2014. FreeDV - open source digital voice.
