WD2XSH/10 QRT at 0000Z. Dale, W4OP, at 160 miles had solid copy of the MFSK16 signal all thru the day. Fred, KN8AZN at 460 miles reported first copy a little over an hour before sunset. Now to find the problem with a frequency drifting HP3586B :( Hope it's the oven driver circuit instead of the oven heater. Dex, W4DEX, WD2XSH/10
