Modifying the Yaesu DR1 Repeater for use on Allstar

So why would you want to interface a digital repeater with lousy audio to Allstar that has in most cases exceptional audio. The answer is you would not or you should not. So then why this article? Well it turns out in the case of the DR1 (and DR1X) you cannot mix analog audio when the repeater is in a digital mode. The DR1 or DR1X must be fixed in FM (analog) mode both in and out. So that's a good thing, no RF digital audio on Allstar! The DR1 makes a rather good (especially for free) analog repeater. It covers either the 2 or 3/4 meter bands with built-in PL or DCS tone signalling. The repeater as you can see in the photo below is made up of two Yaesu FTM400DR transceivers, a switching power supply, and all the glue electronics to make it a repeater.
