I am up in northern Sweden as SM0FOB/2 and not so far from the Arctic Circle. The Sun is down only for 1 1/2 hours and the conditions on the HF bands are noneexistant. But on 50 MHz there are openings almost every day. I have a very primitive set-up for 50 MHz on a balcony. An old 144 MHz 5/8 lambda whip antenna with magnetic mount is hanging losely upside down on a gutter. The antenna acts as an 1/4 lambda on 50 MHz and the gutter as the ground plane. The rig is a Yaesu FT-857D transceiver. I have liimited the output power to 40 watts because it may be some hazardous risk sitting so close to the antenna :-) The power supply is a car battery. With this set-up I worked JW7QIA on Svalbard on June 27.
