I have run into this problem several times and have found that bonding the PS-7 to the TR-7 with a separate piece of braid pretty well solved the problem. I am not sure why, since the negative power lead is pretty heavy, but the added braid did the trick.
For any SR-2000 owners who might be reading this, the same bonding will increase the power output of the rig by a noticable amount. 73, John, W4AWM ************************************** Get a sneak peek of the all-new AOL at http://discover.aol.com/memed/aolcom30tour
