FCC ASSIGNS CALL LETTERS TO ARRL 600 METER EXPERIMENTAL GROUP

Wednesday, 22 June 2005 - Washington, D.C. - The Federal Communications Commission has issued the call letters WD2XSH for the 600 Meter Part 5 Experimental operations to be conducted by the ARRL 600 Meter Experimental Group. The actual grant of license will be done in the normal course of operations by the FCC. (more at 500kc.com)

23 US Amateur operators selected for experimental project.

"NEWINGTON, CT, Apr 22, 2005--The ARRL has applied to the FCC for a Part 5 Experimental license on behalf of a group of radio amateurs interested in operating in the vicinity of 500 kHz. ARRL General Counsel Chris Imlay, W3KD, announced the filing during a meeting of the ARRL Executive Committee April 9 in Denver. The experimental application was among several items the EC dealt with in addition to the previously reported recommendations to the ARRL Board of Directors regarding a planned regulation-by-bandwidth petition.

If granted, the two-year Part 5 license would permit experimentation and research between 495 and 510 kHz--just below the Standard AM Broadcast Band--at power levels of up to 20 W effective radiated power. Modes would be CW and PSK31. ARRL Member Fred Raab, W1FR, of Burlington, Vermont, would manage the project, which calls for 23 discrete fixed sites across the US. The license application requests authorization for experimental stations at Raab's QTH in Vermont as well as at sites in Arkansas, California, Colorado, Illinois, Louisiana, Massachusetts, Minnesota, Mississippi, New Hampshire, New Jersey, New York, North Carolina, Oregon, Rhode Island, Tennessee, Texas and Virginia".
