Thanks Don,

Yes agreed.... I just advised was looking at two options.

I had already been sent an email asking was this limited to KX3 only? 
The answer would be no hence the "dumb" option.

UK has 472KHz-479KHz available to full licencees with a Notice of 
variation to the licence.

The option equates to either operate with the KX3 in the 'normal band' 
with no frequency feedback so you will need to know what the transverter 
LO is set to and you need to be sure you set the output power low or I 
believe you can set it to a transverter band and then a couple of 
options become available, being the IF and the frequency display (as you 
say). The RF out is also dropped to 0.1W by default. A quick test seemed 
to show the RF out was c0.1W no matter what the normal power level was 
set to but was a really quick test before had to run as got normal day job.
