My erratic whistler problem on PRR A5 , after trying several Railsound boards was resolved after I changed the radio receiver brd ( R2LC / Radio Receiver (C13 code), part # 691R2LCC13, $45.00.....
If anyone knows why my Lionel “Heisler #3” engine shuts itself down when slowly crossing two fastrack 031 switches ( #6-81253 & 6-81254) connected back to back please send suggestions. Appears collector is just a 1/16” from hot rail when it stops. Thought twice about rebuilding collector pickups!
