Signal Generator Help
#20

Hi Captain, one problem with connecting a frequency counter to the RF output is that the counter needs a certain signal strength level to operate properly. So when you turn down the output with the 3 position step control or the RF output control, the signal level can drop below the strength needed for the counter. That’s why I altered my SG-8 as in post #14. I repurposed the AF input jack, as I have no need for an audio input to my generator, and wired it through a DC blocking cap to the input to the attenuator, thus insuring full strength to my counter regardless of what the attenuators are set to. Something you might want to consider. Your generator looks pristine, good catch!
