Dear Flex CW guys, I am having a really difficult time finding zero beat. I guess the most obvious way is to use a very narrow filter and center the desired signal in the narrow bandpass. But that is a lot of mousing when you are trying to get some just discovered DX. I wonder if anyone else would find a traditional "SPOT" button useful? that gives you a slected level of your own SIDETONE that you can compare to the other station and find the match. I have been unable to do that with the SDR. Any suggestions?
I also like the idea of a zero beat indicator like the ones developed for the K2 and the QRP community such as this from Jackson Harbor Press http://jacksonharbor.home.att.net/zerobeat.htm Or how about the magic method that Kenwood offers in the TS-570D and the TS-2000 where it does some sort of AUTOMATIC ZERO BEAT? does anyone have experience with that technology?
