Re: LF: Re: US 500-kHz band plan

Jim,

I did post a email on this a short while ago, Gus , I thin was the only one 
to  respond and  subsequently lowered his operating  frequency to  fall 
inside the , set 502.4 usb dial  frequency in use in the  UK.
As the  European allocation looks to  be  wider than the  Uk, are we 
expecting the  UK 3 Khz  allocation to  remain as is, if  and when the  band 
is formalised ?, in which case loosing 200 hz may not be the  most sensible 
option ...
As by definition , if you  can transmit wspr  you  must be  able to  move 
transmit  frequency (noting Andy's new beacon) establishing an over lapping 
100 hz section may be a reasonable  compromise ie move the  dial frequency 
to say  502.5  or  499.5 , leaving 100 hz in band for uk access
