[Elecraft] Legal Limit With FT8

[Fred Jensen]

Returning to the original subject ... I've found:

1.  Power, by itself, is usually one of the lesser factors in such cases 
of interference.  It does come into play in #3/#4 below

2.  Audio input level is a big contributor when it's set too high and 
you're saturating the PA.

3.  Phase noise may be the largest contributor to the interference that 
plagues many.  There was a period, around the beginning of the 21st 
Century, when some of the most popular transceivers had a fairly high 
level of transmitted phase noise.  It was commonly high in the same 
transceivers that exhibited heavy key clicks.

4.  Strong enough phase noise into a receiver can generate it's own 
phase noise internally.  My TS-850 suffered from this problem when KF6T 
was on about 2.5 km from me.  It wiped out the entire band, while on my 
K2, Jack's phase noise was only about 5 to 7 kHz wide.  Still too much, 
but nothing like the TS-850 appeared to indicate.

5.  Saturating the core of an RF transformer/balun is almost as loud a 
noise as dropping your rifle while in formation. 😉
