Excellent Ed.... I to am glad to have added the MR85! Waiting for the ST-2 myself.... have tried several antennas and definitely know that it makes a difference.
Amazon just got some ST-2's, so I decided to get one since I have no confirmation that the company with the Metz actually has them in stock. If they both arrive I can return either one
...
Well I confirmed that the Ham Radio Outlet did not have any Metz in any of their locations so I am very happy that I had ordered the ST-2 from Amazon when they got them back in stock!
