[AMRadio] Bugged by CW?

[Rob Atkinson]

Hi Bernie thanks; okay none of what you suggested applies but thanks
anyway.   It's a known problem but so few customers use it for AM they
probably never cared.  I will get a Ranger or something working and
kiss it goodbye one of these days.   the power reduction in the menu
does not affect the range of the PA collector current adjustment pot
(power out) and I never see any indication of the ALC nonsense.  I
heard they fixed this problem with the later rig they brought out but
it is not analog at all.
