In the absence of any further advice, or useful comments
Its running again, unchanged, on the original frequency.
And observing that several others are still in the 503800 - 504000 region
503875Hz

Well Rik I am glad you used the word "Over regulation" if you are only talking about a sensible and locally agreed arrangement like me taking my low-power beacon off when requested then I am not against it (The fact I am identifiable by virtue of CW means I can be contacted to say, turn it off).
Your comments about other countries having the same band is well taken. I thought DL's could set up camp anywhere but had to be fixed frequency and LA , OZ had oodles of spectrum to VFO around.
At least in the Wild West every body had a gun!
I hope you understand I am just putting the counter view to a carve up of 500kc/s it looked like a land grab to me very reminiscent to the Wild West!

Pete,
I agree that there is no need for strickt regulation (and certainly no overregulation).
But some agreements to "live and let live" will help. At least to me it makes sense that automated operations happen at the band edges (as it is done now most of the time).
I am afraid that the "wild west" will lead to will lead to wild west situations (where often a lot of fighting is involved).
Regarding 501-504kHz: this is certainly not UK only. Also ON, PA, OK and EA are limited to this band.

I operate a low power Beacon on 501.15kc/s so I bag that frequency now. I have already been shooed off 500 at week ends, but to bag the frequencies I guess it needs to stay on 24/7. I also some times operate at the upper band edge so I bag that frequency also. I will be issuing a list of my favourite frequencies to bagsy them as well shortly.
Rik .. EU station have plenty of channels outside the UK 501 / 504 to play on.
This is the RSGB style channelisation of 2/70 in the early 70's all over again. IMHO this band should be like the Wild West no, "no go" areas.

This seems a sensible approach. Time division. Keep to the same freq in time slots.

Hello Graham,
I would suggest to have all digital modes as close as possible to the band edges, leaving the band centre for CW.
For WSPR there are currently 2 segments: one for EU stations to transmit on (503.9kHz +/- 100Hz) and one NA stations to transmit on (501.1kHz +/- 100Hz) to avoid local QRM (or better said RX overload).
So 503.7kHz +/- 100Hz and/or 501.3kHz +/- 100Hz for other digimodes ?
It would be possible to have a single data segment for EU and NA it we go from frequency division to time division: if all EU stations would transmit in the xx:00-xx:02, xx:04-xx:06, xx:08-xx:10 ... time slots and all NA stations in the xx:02-xx:04, xx:06-xx-08 ... time slots they can use the same frequency without local QRM.
But this would require a minor chang in the WSPR software (and maybe also other software).

Alignment of (Narrow Band) DATA and WSPR frequency’s on the 500 KHz band.
The original wspr frequency 502.4 was defined as the working frequency to utilise the ‘clean’ area just under the 504 harmonic, whilst avoiding the various beacons running across the 501/504 band at the time. However, time has moved on and there are now numerous ‘dial setting’s’ in use both sides of the Atlantic.
Due to an apparent increase in the side band noise from the 504 signal , possibly by enhanced propagation , the ROS MF (100 hz b/w) working frequency is to be re defined as 500 USB dial set giving a centre carrier frequency of 501.500
Due to Ae bandwidth and perhaps alignment with other band’s, I would suggest the original WSPR 502.4K is replaced with the lower frequency of 495.9K , thus restoring the System’s coverage and facilitating changes of mode etc within a narrow bandwidth.
I don’t see this detracting from the monitoring of spot frequency beacons over 505Khz , but more appropriate to transmitting stations , which by the nature of the antenna arrays are not able comfortably to qsy from top to bottom of the band without re-tuning, not always a simple option.
Comments or suggestions please ?.
Graham
