I took my research one step farther and e-mailed Bob Heil direct, told him I was running a TS-130S with a D-104/T-UG8 base, included the fact that I usualy get good audio reports, however if I wanted to improve my sound, what microphone would be my best choice.
I also indicated that I liked the looks and specs on the Heritage, and why it wasn't indicated as a good choice for the Kenwood TS-130S.....
His answer was....
"Hands down the PR-781"
He went on to say that the PR-781 is his best work to date in a microphone for amateur radio, and he feels it would make my rig sound it's best over any other model in his line up......
It's not his most expensive, but it ain't the cheapest either. I've got the stand and boom, but I'd still need to purchase the correct cable, and either a foot or hand switch, so I'd still be looking to spend somewhere's in the $225.00 range for a complete arrangement.
That's not going to happen anythime soon......
