Cobra 29 LTD Soundtracker - Clarifier unlock
Does anyone know the proper parts to remove to do the unlock? The diode and resistor numbers are different on the soundtracker board...
Thanks in advance,

1)Remove D-18 , R-110 , C131 and R-112. 2)Put jumper were R-110 was. 3)Take orange wire from delta tune and unsolder it from board then resolder it to Tr-23 (Solder to the pin closest to front of board. It should have around 8 VDC on this pin.) 4)Put radio back together and if all is done right you should slide transmit 5-6 KCs up and down. For more slide change D-16 to a 1N-4007

Change varicap diode D16. I don?t think this will work as 1N4007 is a general purpose 1 amp 1000 volt plastic rectifier diode and not a varicap diode.

What is the point in making an AM only radio shift?

The only reason I would want shift on AM only radio is if it's capable of 10k shift so I can go between channels.
Is this what's often referred to as freebanding ? I honestly don't know this is the first time to ask someone what freebanding is.
