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 the modulation methods. ETSI is considering a revision that will allow a spectrum mask with some of the modulation components falling outside the band. However, field testing has indicated that the sideband limits will have to be lower than originally desired to prevent interference in the adjacent amateur band.

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. Regards, Jack Jacob Z.
