[Elecraft] K3 AM TX - Questions and Observations

[Andy Wood]

I have recently been experimenting with AM on the low bands using the K3. The
addition of Sync AM RX makes such a difference!

I have noticed on AM TX, use of compression, at any level, causes some
distortion of the waveform at the zero crossing (when viewed on an
oscilloscope) - not really an issue, but I wonder if anyone else has come
across this? It also appears nearly impossible to exceed 100% modulation,
regardless of the mic gain setting.

I also have a question regarding asymetric AM modulation and the K3 - is it
possible for the TX to exceed 100% positive modulation whilst maintaining
less than 100% negative? Being only new to the AM mode, I am not sure if it
is possible with any TX that uses low level modulation. Any info greatly
appreciated.
