Proppy: Online HF propagation predictions using the ITU Recommendation P.533-13 Propagation Prediction Application.

This article compares two commercial vertical antennas for the 4-meter amateur radio band: the Watson WVB-70 half-wave and the Sirio CX4-71. The Watson measures 2.03m in length, costs around £40, and exhibited adequate performance but required additional waterproofing after rain affected its VSWR readings. The longer Sirio CX4-71 (3.02m) performed noticeably better, delivering signals approximately 2 S-points stronger than the Watson. The Sirio demonstrated high build quality, a stable 1.2-1.4:1 VSWR, and weather resilience, though minor VSWR fluctuations were observed during rain and frost. Both antennas are half-wave designs requiring no ground plane radials.

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.
