This proposal is common sense, considering the Primary
users are all CW navigational safety BEACONS and surely OFCOM and
the RSGB know this. If they arrived at any other decision it would
be unwise. It is also prudent to keep the NDB network alive in the event
that the GPS system is Zapped. In fact the DECCA system probably should
have been retained as a standby.
There are still some MF/HF ssb frequencies in use and
this is also a good idea in the event that INMAR sat and associated marine
satellites fail or get zapped.
Modern technology has produced some fantastic TOYS and
SYSTEMS but FRAGILE and vunerable to cyber attacks, emp's and in
the hands of third parties where the user has no control.
On the other hand a couple of Radio Operators with
simple CW transmitters and receivers are totally in control of a communications
link and multiply this throughout the country and you have a complete
communications network with multiple independent alternative
links.
This is the way it used to be and as they
say HISTORY REPEATS ITSELF.
Maybe Valve/Tube technology ought to be revisited as well
if we want robust devices. Modern chips only need a trace of electrostatic
discharge when you comb your hair of walk on a nylon carpet to get zapped or a
rain storm destroys your RX front end !!
I understand some countries still use TUBES for radio
communication equipment not because they lack so called modern technology
but because they are playing safe when it comes to reliability and
robustness.

The band should be licensed for CW operators only so
that they could recognize and read the CW beacons and AVOID
them.
Has OFCOM thought of this. Neither should
there be any amateur unattended BEACONS to jam the Primary user Beacons
even unintentionally.

Hi all. Following on from Tracey's info what would be the
various regulators reaction be if we were crowded out of this band as we
only have on a secondary basis. 73. Ken. M00KHW

Hello Ken
I doubt it, but you never know.
I've just checked our Received In Europe (REU) database and there are
some 29 inactive NDBs listed in the 472-479kHz range.
If they were all to become active that would roughly double the number
of NDBs in that segment.

band allocation
Dear all
LFs
With the WRC-12 new LF band
allocation is it possible that any dormant NDBs there will be resurrected
to justify their slot in the band?
