Bob brings up a good point. The band edge is at 135 kHz and the modulation
sidebands must be down to the specified level at that frequency which limits

You should be aware that there is a UK amateur radio band at 135.7 - 137.8
kHz. Please keep that in mind both from an interference and from an immunity
standpoint. You'll need to check the RA's website for technical limitations.
Another resource is the RSGB's website at www.rsgb.org.uk.
I generated and posted this document in 1999 and some parts are now out of
