So I convinced my mate to come back to 11m after an absence of some 30 years. Earlier this week he acquired the latest green/black display Ranger 2950DX from the Bay. It came complete with the e-chip for adding 11m but no instructions as to where to plug it.
There is a vacant 3-pin socket on the PCB near the noise blanker switch which looks like a perfect match for the trailing plug attached to the encapsulated e-chip. Is this where it should be connected? Also, after connecting the e-chip, does the radio need a factory reset to re-initialise it and, if so, how?
