Re: COBRA 148 GTL ADDING FREQ. COUNTER

Ah right, I did actually think DYI was a model, I wasn't playing grammar police. :D

I cant help you on this one as i only know how to connect up a 3900 type counter [CRT superstar kf v1] for the 148, Theres plenty of instuctions around for this maybe it could give some clues, You never know.
