The greater difficulty is in measuring the occupied bandwidth of very
narrow modes (e.g. JT65, JT9, FT8, RTTY or even CW) due to the 2 KHz
minimum span of the P3 ... a 500 Hz span would be better for measuring
narrow modes.
Not so difficult at

Jim - in this context, are you using the definition of "occupied
bandwidth" as in ITU RR 1.153, i.e. 99% mean power? If so, how do you do
that with the P3 SVGA?
For CW, I transmit a long series of dits, put the P3 in peak mode, and
accumulate

Whilst it's not completely accurate, it is very easy to approximate
