Hi Mal Thanks for the info. Just thought some one may be interested in a ready made tx for 136 which is being auctioned on Ebay. I have a QRP TX for the band but will be building a PA soon. Once agai

Hi Chris and LF It seems every action has unintended consequences. In writing the mail below I was trying to make a point about the escalating use of band width per transmission. That Olivia thing is
Hi Mal and LF I am disapointed in you Mal to be considering an envelope detector. A true CW man, I would have thought, should only entertain the use of a Cohere detector! Having played with them, I w
