1. LF: SSB modulation for WSPR (score: 1): Author: LineOne <[email protected]>; Date: Wed, 21 Oct 2015 10:15:15 +0100; So far the only person to decode my WSPR transmissions is Joe, DF2JP. I made a drive unit for 136kHz to utilise 4 different methods of modulation including quadrature switching for SSB.

Re: LF: SSB modulation for WSPR (score: 1): Author: Andy Talbot <[email protected]>; Date: Wed, 21 Oct 2015 11:13:57 +0100; Need to ask the obvious - is the frequency recorded in Joe's spots the actual one you were transmitting on? Exactly, spot on, to the Hz ? When you say I and Q are "somewhat different", do you mean,; /rsgb_lf_group-archives/html/rsgb_lf_group/2015-10/msg00330.html (11,247 bytes)

4. Re: LF: SSB modulation for WSPR (score: 1): Author: LineOne <[email protected]>; Date: Wed, 21 Oct 2015 20:47:11 +0100; Unequal in amplitude Andy. the cure was simple but ridiculous. I had set the internal preset balance with the I & Q gain pots about halfway but what I didn't check was that I & Q remained identical; /rsgb_lf_group-archives/html/rsgb_lf_group/2015-10/msg00338.html (12,215 bytes)
