An update....... The Rig was all OK. So....... I started looking elsewhere.
The problem turned out to be the UnUn. Replaced it, and everything seems to be OK
. I spoke with Bob at Balun Designs and he thinks it may be the connector in the UnUn box. I am sending it out to him to take a look at it.
Thanks for all the replies. Next time, I'll get the dummy load out and start checking before I automatically think its the rig.
