Re: QDX FST4W-300 Transmits only 2 tones? #qdx


 

Hello Alan?

Still a pending issue... Thought to be due to floating point precision limitations. I need to investigate..?

Subject: [QRPLabs] QDX FST4W-300 Transmits only 2 tones? #QDX
This subject has been raised before,? [
/g/QRPLabs/topic/94416795#94434? ] smaller frequency
shifts than WSPR not being transmitted correctly.

I attach 2 shots, one a Softrock/WSJT-X and A QDX/WSJT-X.
While due to a hardware mod I can only use my version 1 QDXs with the
1.02 firmware it shows similar to a previous post.

Has this been rectified since October 18? I see no note of this in the
1.06 firmware.
