Hello again larry, Now that you pointed it out, I already know about the message you indicated. In fact, it turns out to be one of the responses to one of my postings.
Subsequent to this particular posting, he and I have been communicating a bit more one-on-on (off-list) with even more Q&A on the topic. So as a result of his kind assistance and patience, I am now aware of even more than what is in the group's copy of the message. And now that I understand even more of what he was saying, I agree with you that it is a good starting description. Thanks again, <<< vern (W6NCT) >>>
