Dave,
I think I found your problem.
15.430 Mhz isn't in the ham bands!
I too heard N4RT, N3JDO, and K7EWE testing.
I think the band is improving. Unfortunately, my neighbor called and said I was interfering with the Seattle Seahawk game and his AM radio. Though we have 10 acres, the end of my longwire is just 200' from his home down the hill from us. The Alpha 89 linear running the legal-limit saturates everything he owns apparently! I'm stuck with 80 watts from the 32V3 which is more than enough if conditions are good.
Hope to work you soon ... 73's
