[Elecraft] KX3 - UHF emissions

[Dave]

I can back Darren up on this, sprogs and sproggies are common slang words 
used in Amateur Radio and the Radio/TV industries in the UK to mean 
spurrious emissions.

So, at a typical Microwave Roundtable you might hear someone say "Look at 
the sproggies on that!" when connecting the output of an oscillator or 
amplifier to a spectrum analyser.

It can also mean a small child or baby, as in "I see she has brought her 
sprogs with her" it was also used in the RAF as a description of a new 
recruit, possibly putting 'frog spawn' into one word, as the recruit was 
often said to be 'as green as a frog' as they didn't know much.

What frequencies are these emissions on specifically?  As I'll get out my 
portable spectrum analyser and go and look for them on my KX3 if I know 
where to look.
