John,

there are low-cost and readily available xtals for 11059 and 22118 kHz.
Devided by 22 or 44 this results in 502.69 kHz.
In the better electronics shop you might find 28224 kHz xtals, devided by 56 = 504 kHz. Even more exotic (but some kind of standard) is 49152 kHz, devided by 98 = 501.55 kHz

Quoting John W Gould <[email protected]>:

I'm busy building a DDS, but if that fails to work in a sensible timescale
I'll need to be xtal controlled, so an agreement where we might cluster for
QRSS/DFCW might be worthwhile.  This might also be helpful for others.  Are
there any obvious frequencies that are divides from standard crystals?

LF Group,

Is anyone willing to propose a voluntary bandplan for the UK 501 kHz
allocation? We could follow the same sort of scheme that is followed on 137
kHz, with separate areas for CW, digital and QRSS/DFCW modes. The 3kHz
available is broadly similar to the 137 kHz allocation, and won't be enough
to permit much by way of "broadband" operation (MCW, DSB-AM, SSB, or even
drifty CW etc)

Ofcom has announced today that a limited number of SRPs will me made
available for 12 months from 1st March. See
