DIGICOM.1                                                                                
THE REASON FOR THE MODIFICATIONS:  SOME RADIOS ARE PRODUCING A STRONG
SECOND HARMONIC AUDIO SIGNAL AT 2400 HZ. WHEN THEY RECEIVE A STRONG 
STATION. WE NARROW THE BAND PASS TO 2200 HZ AND DOWN SO THE BOARD WILL
NOT HEAR 2400 HZ. R1 AND C1 DOES THIS.
WE ALSO INCREASE THE LOC RESPONSE TO A FASTER VALUE SO THE 2211 LOCKS IN
ON A SIGNAL FASTER. THIS IS THE C2 FUNCTION.
ADDING THE TRANSISTOR LOWERS THE LOAD ON THE 2211 AND HELPS WITH ITS
CROSS OVER FREQ RESPONSE.
THE 3 .001 CAPS REDUSES THE RF PRODUCED BY THE 64 AND BYPASSES IT TO GROUND.
A SMALL AMOUNT OF RETUNING OF THE RECEIVE ADJ IS NECESSARY.
THIS WILL HELP MOST BOARDS WITH STRONG PACKET SIGNAL AND RECEIVE PROBLEMS.
