If anybody finds a speaker to amplify the sound of TRX1 please let us know. I have tried 2 different amplified speakers that work great with Pro 106 but will not work for the TRX1. Also does anyone know if the TRX2 has the same setup as the TRX1 concerning the speaker and using amplified speakers. I can not hear the TRX1 in my truck at all. This problem was solved with other scanners by using a amplified speaker, but with the TRX1 its a no go. Thanks
