Radio band details for Spain. At the moment practically a bare template that could apply to most Euro countries. So - I would be most grateful for your assistance filling in the gaps... if you can help improve this page (detail-wise, I LIKE the colour scheme!), please e-mail to the EuroScanner mailing list at euro-scanner@grid9.net addressing your comments to my good friend Rf-man - thanks.

              "The most interesting part of this band is between 70 and 87.5 MHz.
              There are lots of services there (most of them private companies, working
              simplex or, sometimes, semi-duplex). There's also an emergency service of
              our National Health Service (ambulances)
              The most important service in this part of the band is the Guardia
              Civil (a kind of rural police, performing also some special services) Low
              VHF mobile comms. They use a quite complicated system, sometimes in
              simplex, sometime duplex or semi-duplex, using 41 channels both in the 75
              MHz segment and the 84 MHz one. If I was sure (I'm not) no Guardia Civil's
              personnel monitors this list, I could describe you an interesting system
              of doing comms here, in Madrid, by them." - email list posting

             118.07 because the second decimal is only ever 2 or 7 and so there is no ambiguity.

             ... then :
               If a NEW channel name is 10kHz ABOVE an old 25kHz channel, tune DOWN 1.666
