LF: 500 more

["mal hamilton" <g3kevmal@talktalk.net>]

   With the recent influx of PA stations, new ones appearing every day, it might be the time to request a larger 500 band, 3 Khz is barely enough for QSO purposes, also a reduction in unattended  BEACON acty would be useful to avoid qrm.

When acty increases and more countries permit 500 operations there will not be enough space.

Receiver selectivity also needs to be checked, the old TRF sets will have to go.
