Park VE-1368 activations - North Maple Regional Park
55 QSOs ranging from Vancouver and California to Spain. Including few park to park QSOs.
32 QSOs on 2nd activation weekend, testing the antenna in 17m, 15m, and 20m. Three DX QSOs with Germany, Spain (park to park), and Western Sahara.
Park VE-5314 activation - Tottenham Conservation Area
50 QSOs ranging from California to Italy. Including 6 park to park QSOs.
Activated the park using a triple mag mount without the ground radials.
It worked great in 40m but there was lots of RF common mode interference on the bands 20m, 15m, etc.
On the roof with an ugly choke
Ugly choke and grounding braid
Beautiful view from my operating position
Ground point on the frame. One braid for the mag mount and the other braid is for the radio.
