Location: The Cornell Cooperative Extension (Solar Building), 50 W High St (Rt 67), Ballston Spa, NY 12020
Activities: New/Used gear for sale or trade. VE test session – Email Jim, (email@example.com) for test details.
ARRL DX SSB Contest This Weekend. Starts at 7:00 PM EST on Friday, and ends on Sunday at 6:59 PM EST.
Objective: To encourage W/VE stations to expand knowledge of DX propagation on the HF and MF bands, improve operating skills, and improve station capability by creating a competition in which DX stations may only contact W/VE stations.
W/VE amateurs work as many DX stations in as many DXCC entities as possible on the 160, 80, 40, 20, 15, and 10 meter bands.
DX stations work as many W/VE stations in as many of the 48 contiguous states and provinces as possible.

The ARRL is asking members to comment by April 19 on possible changes to the League’s HF Band Plans suggested by the HF Band Planning Committee. The survey is part of the committee’s efforts to tweak the band plans for the RTTY/data/CW portions of 80 through 10 meters — excepting 60 meters. The committee developed its suggested revisions to the voluntary band plans after reviewing some 400 member comments in response to a March 2014 solicitation that sought suggestions for using the spectrum more efficiently so that data modes may coexist compatibly.
“The committee concluded that most of the concerns voiced by members could be addressed by modest adjustments to the existing band plans, and mainly by confining data modes with bandwidths greater than 500 Hz to the FCC-designated segments for automatically controlled digital stations (ACDS) and to parts of the RTTY/data subbands above those segments,” ARRL CEO David Sumner, K1ZZ said. His article detailing the committee’s suggestions will appear in the April edition of QST.
The proposed changes differentiate among ACDS, narrow RTTY/data modes having a bandwidth no greater than 500 Hz, and wider data modes having a bandwidth up to 2700 Hz.
