[Lowfer] TACAMO on 27.2 kHz

[Graham]

I have too and on my grabber 17.9 looks to be more 17.8 and 22.6 looks 
to be more 22.7. Frequency lists typically show 17.8 and 22.7 so I have 
adopted. I must take a bit of time of check the calibration my calibration.

The question then is, what are we considering the "frequency" - the 
center between MARK and SPACE of the various FSK/MSK transmissions or 
the MARK or the SPACE frequency
