Dear LF Group,

I still haven't replied to Fritz Raab, W1FR, regarding the WD2XSH US band 
plan which he is apparently coordinating - you may remember I posted the US 
proposals, which he sent me, a couple of weeks ago, but have not received 
any comments from other UK/Eu stations. I think I should reply with 
something, so now is your chance... The proposal relates to the US 
allocation extending to 495 - 515kHz, and how that would fit in with current 
UK and Eu beacon operations. The content of the e-mail is below. The issue 
is that they would like to make a 501.0 - 501.2kHz WSPR sub-band, to fit in 
with the various other proposals. Various other types of beacon modes are 
allocated frequencies outside the UK/EI/ON 501 - 504kHz range, while 501.2 - 
504kHz is allocated to "general comms". Retaining frequencies just below 
504kHz would divide their "general comms" band in two

I don't think there is anything preventing us from doing this, it is just 
the inconvenience of turning the current band "upside-down". Let me know 
what you think!

Cheers, Jim Moritz

>>>From W1FR:

Greetings:

     Thanks for the comments on the band plan, passed
along to me by W1XP.

     About a month ago, a modification to the WD2XSH
license was approved that adds stations and gives us
access to 495 - 510 kHz.  Perhaps half of the 42 stations
will eventually get on the air.  Because of NDBs, some
stations are limited to parts of this band and we will
have two calling frequencies and two beacon bands.

     A draft of our new band plan follows.  Of particular
interest is WSPR.  As I see it, our options are:

(a)  501.0-501.2:  Conveniently on one side of our comms
     band.  Will not overload WSPR receivers near 504 kHz.
     Apparently in EU CW-beacon band.

(b)  503.8-504.0:  Apparently same as what you guys are
     using.  Cuts our comms band in the middle.  Nearby
     stations may overload US receivers trying to hear EUs.

(c)  503.9-504.1:  Same problems as above with cutting
     comms band in two and overloading.  Conveniently
     straddles both G/ON/EI and Canadian bands.

     Any further thoughts you may have will be
appreciated.
