[Elecraft] Fw: K3/K144XV/P3 Signal Strength Readings

[Geoffrey Downs]

No comments from Elecraft or elsewhere on my posting below, so perhaps my 
conclusions are wrong or maybe I'm just expecting results too quickly. Any 
views anyone?

By the way, as with most postings that raise specific issues, it's not 
intended to convey general negative vibrations about the K3/K144XV/P3. I 
would not part with mine :-)

73 to all
