Hi Jef, Thanks for the photo on the Hairpin match. To fill in a detail, the instruction text linked to specifies the length of the wire at 5 inches, though it doesn't say if that's the exposed part, o

Anything 2.0 and below is fine; you usually won't get into trouble until the SWR approaches 3. Higher SWR at the low end of the band means that the elements are probably a little too short, but you sh

Hi folks, This is tomorrow and Thursday. Possibly. It appears that all of the passes over this part of the planet are outside the operating schedule (between the two days, and after it's over), but it

Ah. The one I have is the Larsen 2/70 from, er, a while ago. I think I got it back in the 90's (aka last century), but it looks like they're still selling it ($140 on Gigaparts). Still working fine. T

An SWR of 6.something suggests that something is not connected, or not connected properly. Mine was only that bad when I had the inside blob mounted 90-degrees from where it was supposed to be. I don'
