Harry W2HRY and myself replaced our 2 meter DR1X repeater with a new DR2X model. All went well and settings are the same for the moment. We will likely move from a CTCSS Tone Squelch to a DCS (Digital Coded Squelch) system in a couple of months.
DCS is a newer and better system from a performance standpoint. It will hopefully eliminate squelch hang and noise.
