Gents, Thank you all very much for the pointers of what I should track down. I may found the culprit in an answering device that was wired in parallel to CO1. I didn't think to look for such things before your hints. Guess I'll find out in the next couple of days if I was right. Thank you all!
With much gratitude, --David _________________________________________________________________ KX-T Mailing list --- http://kxthelp.com/ Subscription changes: http://kxthelp.com/mailman/listinfo/kxt
