Hi Brendon

Spot on..though the bursts of data changing frequency I know as the data transmission..( short bursts , maybe 100khz apart, skipping in frequency.)

Etc.

The othr changes frequency often, but is constant untill changes..following max muf or max range.

Thing is…we are buggered in the respect that all are government approved ( in each country) so there is nothing we can do..however good for tuning up in and trying out amps, tuning antennas etc..lol..
