This is good advice Eric: Please add to it the caution that you want to be careful how many times you clean and how much pressure is applied because if done too harshly or too often you could also run into unsuspected seating issues.
Obviously the reason for the over kill of the manufactures recommendation of *always* using new hardware. If your running a government project not usually an issue (just "charge it to the project"), but if your doing it for yourself it can become very costly very quickly Hi Hi Just be gentle and you shouldn't have any trouble.

In addition to grooves and scratches Metal Burs and stringer materials from previous installs have been traced back to PIM (intermod) at busy (high rf) radio sites. The brass or stainless brush cleaning does help quite a bit, although it doesn't address any previous mechanical made deep center pin grooves from causing grief. I use a small round stainless pipe cleaning brush in the tool box to clean up the inside of >7/8" hardline. Smaller 1/4, 3/8 & 1/2 solder connectors shouldn't be as troublesome. There appear to be a lot of unsuspecting ways to make a diode... cheers, skipp > Eric Lemmon <[EMAIL PROTECTED]> wrote: > Skipp, > > Verrry interesting!
