Not in Indiana, but a comment. I Used one of those Duplexers years ago. Be careful where you locate it. Extremely sensitive to temperature variations. We had it on a mountaintop and retired it after the first winter. Gary - K7NEY - Original Message - From: Paul [EMAIL PROTECTED] To:

The problem with the stability is that most of these were constructed using a Galvinised steel rod to set the tuning correct? Try a replacing it with a more similar metal to copper like brass or copper threaded rod if you can find it. or a plastic rod that has good tempreture charecteristics.
