I am in need of a few TLN1251 cards. These are more commonly known as "private line control modules." They have 2 momentary switches in the front labeled "Operate PL" and "Operate Carrier Squelch."
They have 2 tone decoders on board - 1550 Hz and 1450 Hz. If you or anyone you know has any they don't need, let me know. Thanks, Scott Scott Zimmerman Amateur Radio Call N3XCC 474 Barnett Rd Boswell, PA 15531
