[Elecraft] PR6-10 Poser, Cont'd

[Eric Ross]

I just hooked mine up this weekend.  I was using Ant2, but I don't see
that being a significant difference.  Initially, I was seeing the same
symptom but it went away. I am thinking that a power cycle might have
enabled something, but I am only guessing.  I was doing some contesting
on 6M(local) this weekend and it worked like a champ.  I also have the
sub, and it was also on Ant2 at the time.
