Thanks Bob...glad to see someone else on this list has done what I've done in the past. I too have had no problems putting crystals in elements and having them work properly. The repeater environment is stable; it's co-located with a UHF TV transmitter, and the owner pays close attention to such.
I'm NOT trying to cut corners guys, just trying to do what I've had success with in the past.
