[Elecraft] P3 span changing

[Mike Flowers]

There are apparently some issues with the P3 firmware retaining the frequency and center by band.

I reported one issue where the P3 would return to an entirely different band than the one commanded.  The head of FW for Elecraft confirmed this is a bug that needs fixing.   When that will happen, if ever, is anyone's guess with the K4, pandemic, etc.

In macros I write to change bands and frequency, I find that I must issue P3 commands twice to have the P3 properly centered as I want it.   I issue the first set of P3 commands at the beginning of the macro string, and the second one near the end.  This works for me, so I no longer worry about this FW bug.
