7000DLE perfect QSK?

Postby W1JA » Thu May 17, 2018 4:21 pm

Has anyone else noticed the incredibly awesome QSK performance of the 7000DLE, as reported in Adam Farson's test report? http://www.ab4oj.com/sdr/apache/anan7000dle_notes.pdf
See the CW QSK recovery test starting on page 29.

On page 30, he shows the ability to recover receiver audio between dits running at 60 wpm. The scope photo of the audio shows what looks like textbook-perfect ideal QSK. He also says the 7000DLE "is free of loud T/R relay sounds when keying" (page 34). He tested with regular protocol 1 firmware and regular PowerSDR version 3.4.9.

My 200D can't even approach these results. I've tested it, and I can just barely hear a tiny bit of receive audio recovery at a speed of about 12 wpm. And I could not say my 200D is free of loud T/R relay sounds when keying.

Can someone with a 7000DLE please confirm or deny these unbelievable results?
