Hello everybody. In order to start editing my Bitx40, I take stock of the components I miss. As I chose to modify the code of Raduino, with the version of Allard PE1NWL, I read and translated in

I wonder: has anyone here used DHL and NOT been charged for Customs? Might be a case for removal from hfsigs site. Is there an alternative available from/at that location? India Post is reliable, and

DHL works fine for shipping into the US. ?Other countries, it can nearly double the price of your Bitx40. I would have gladly paid $10 to avoid the 2 month grand tour of the USPS that my package

Hi Al, I found the same thing. I had to change my LSB calibration from - 230 to 50ppm. My USB also changed from 2460 to 2564 Hz but it may have been off before as I don't use USB. I guess CQ WW wore
