Good Evening Gents

Question for you, is it possible to fit a frequency counter to the above 
radio, It would nice to know what the actual 'F' is in relation to the 
scale.
If anybody has done this mod, please advise and if possible supply 
connection details, although the radio is sold i would like to supply 
the new owner with as much info as possible.
