Hi,
I am new to the forum and hope someone can help with this circuit I have found.
I have built and tested it with and it works, up to a point.
The circuit is set up to trigger, with the 100k trimmer when switched from a TX spare channel.
The circuit output works and lights the test LED.
The problem is it will not trigger the relay...
The transistor stage work perfectly when tested separately so I am assuming the comparator is not supplying enough output to trigger the BC 547 transistor.
Can anyone suggest any different transistors or other components that may make it work better?
Regards,
DEEGE
