Antennas : NVIS DX Resources : QSO Party
  • Maine QSO Party - The Maine QSO Party is designed to encourage Maine stations to expand their knowledge of DX propagation on the HF and MF bands, improve their operating skills, and improve station capability by creating a competition in which W/VE, and DX stations have the incentive to work Maine. The MEQP is Maine's Premier International HF Contest.

Software : JT65
  • WSJT-X Download Page - WSJT-X - Weak Signal Communication, by K1JT - offers specific digital protocols optimized for EME (moonbounce), meteor scatter, and ionospheric scatter, at VHF/UHF, as well as for LF, MF, and HF propagation. The program can decode fraction-of-a-second signals reflected from ionized meteor trails and steady signals more than 10 dB below the audible threshold. WSJT-X incorporates nearly all popular capabilities of programs WSJT and WSPR, while adding comprehensive rig control and many other features. Open-source, download latest version for Windows, Linux, Macintosh OS X.
