Subj : ic 718 To : All From : Alan Beck Date : Thu Sep 01 2022 07:42 am I second that. The IC-718 as will all Icom radioes has a funky RF Gain / squelch control you choose RF Gain (input radio signal loudness) and Squelch (shuts of the signal in the reciever. If your seems to be doing nothing, check that control. The one thing I don't like about ICOM. Alan VY2XU --- OpenXP 5.0.56 * Origin: (1:229/426.36) .
