Hi, I have a sidemounted T2X @ 37' which turns a 5L 105CA. The rotator is turning fine but the direction indication got erratic very briefly and then stopped indicating - with the needle pegged to th
Hi Joe, As it turns out it was both the control box and the rotator. After checking the voltage readings between pins 3-7, 1-2. 1-5 and 1-6 (all zero) and comparing against 13.5 v between 3-7 on a go
Hi John, Thank you for your reply and the suggeston. I performed the tests in the manual as mentioned in my reply to W4TV. Tnx & 73 Bob, KQ2M The first thing I would do is perform tests described in

Hi Ed, Thank you for that info. My beverages, aka "Tree-catchers", worked well in the past but they were excruciating to maintain constantly. Then when the Deer Tick population exploded about 20 year
Thank you Jim - I'm going to look into that! 73 Bob, KQ2M My soil conductivity is quite poor here (granite with a lot of "loam" that falls from my redwoods), but my spaced VE3DO loops work well. They
