I have an intermittant PTO indicator lamp on my R4B when using it with my T4XC. It may work all night, then sometimes it will go out and won't come on with whatever you do to switch the PTO in use. In the R4B schematic, it shows Q10 is a switch that is turned off when the transmitter is used for freq control, by a negative voltage on the INJ line to the receiver. I suspect either the transistor or the neon bulb indicator. Has anyone had this problem and what did you do to fix it. Thanks to all.
