I have a Legacy 990 base that won't transmit from the U post to the track. It will send and receive between the base and my two Cab-2's, and it will transmit to the track using a TMCC base connected with the factory supplied Y cable and the TMCC base U post connected to the track. The Legacy base ran hot when new, so I turned the charger off and have been using alkaline batteries since then. The software is currently version 1.2. I purchased the writable modules to upgrade to the current software, as I am about to add LCS WiFi, SER 2's, and MTH DCS, interacting with a soon-to-be-purchased iPad. I had been using Train America Studios Layout Control System on a desktop computer connected to the DB-9 RS232 port, along with the original I C Controls modules to operate the switches and accessories. Does anybody do out-of-warranty repair on Legacy 990 bases? I think Dale Manquen did. Or is it repair-by-replacement, and can I get just a legacy base without having to purchase the set including the Cab-2? I did read on Dale's website how to measure the 455 KHz signal with a diode, resistor, and DMM, but am pretty sure there is nothing there. Any help would be greatly appreciated.
