I have an E8 ABA unit, C&NW #20-2237-1. It doesn't operate properly. About half the time it works on DCS. Turning power on and off sometimes gets it to operate. This is an early unit made before the command base (TIU) was available. I sent it to MTH for repairs and never had it out of the box to test since 2001. I replaced the 9 volt battery.
I want to send this unit in to get it repaired, or upgraded. who can do the work?
