Many fewer harmonics generators now than in the past.
WA1SXK and I went on the war path for the last several years contacting
everybody we saw and getting them fixed.The FT8Noise paper on my QRZ page is
the result of testing with numerous rigs and explains it all.

On Tuesday,
TNX Mike! I am amazed how many people I keep seeing on the air who are
transmitting audio harmonics and don't understand that they need to have
the XMTR frequency changed if they want to select XMIT offsets lower
than 1500 Hz. They insist that they have checked their audio and it is
not
No -- the target is not good quality of signals -- that's misleading
tooit's all about shifting the audio (actually shifting the suppressed
carrier).
#1 Avoid transmit band edges (rigs can actually transmit outside of their
bandpass)#2 Avoid harmonics#3 Avoid non-linear power behavior (some
Hi Jim
I agree - it is a very frustrating situation, especially for foreign users
with English language problems.
The target is the good quality of signals. So the title:
"Split Operation" is bad. Split operation is one of the ways to get it.
"None" is OK.
"Rig" is not OK, it should be "Rig

Hi Jim and all,
I support this proposal. I know that on the rig's point of view the
functionality is the same as in the classical "split". What is seen on the
band may or may not be the same depending how the user selects the
transmission frequency.
In addition some words could be added to note
I disagree with the progam/documentation change request.
Split is the radio function invoked for 'rig split', and it is
documented well online,
how the system uses rig split to control the audio frequency best use

I feel; 'TX Shift' would cause more confusion, as it still does not
