This past Saturday, we enabled the 145.270 and did not hear it act up, so we have left it turned on. Please try it out and see if it acts up for you. If so, you will hear the squelch hang open after a person talks, and it generally sounds like some type of digital data.
E-mail myself, KB0NHX, direct at kb0nhx@nixahams.net if you see it is having problems.
Thanks for your help!
