I have their tone-out frequency as 155.01 pl 146.2. I've been in Dumont for the last 3 months and have not heard them being toned out. I hear the REFD and REPD just fine but not heard the REVAC. I'm using a BCD396T with an RS 800 antenna. The frequency and/or pl maybe wrong. If so, any help would be appreciated. Thanks, Chuck.
