My experience with my SG-8 is that it’s not very stable, necessitating constant readjustment. My alteration allows constant monitoring of the generator frequency without constantly connecting and disconnecting the counter to the RF output. Up to you. If you want to do the change, disconnect the AF INPUT jack from everything circled in red, add a .001mfd cap to the jack and the other end to the circuit with the green arrow! Now, no matter what setting you use for the attenuators, the counter always gets full signal level. Using BNC jacks makes it easy to connect a modern lead with BNC ends to the input of a modern frequency counter. This is a fairly quick and inexpensive change to your SG-8!


Hi Ron, I have a .001 MFD 2,000 VDC Ceramic Disc Capacitor, would that work for the DC Blocking Capacitor for the above modification?

Also is the spot pictured below the spot I would attach the old AF  Input Jack and capacitor modification at?

   

Thanks,
