Hi
I need help to connect a frequency counter to the rear external oscillator of  Atlas 210X transceiver
 I have 2 wires from frequency counter to connect to pins of external oscillator but I dont know what pins should be connected and also whether to keep the pins bridged 2 with 3 and 5 with 6
 I will appreciate any help
 Thanks and regards

According to the manual the rear connector is for an external oscillator (model 10x). If you install that you have to remove the jumpers. The manual also tells you that removing the jumpers will disable the internal oscillator.
The schematic tells you that the oscillator output goes via pins 2 and 3 of the socket, 5 and 6 is the supply voltage. To couple a counter would mean to loosely couple it to pins 2 or 3. Loosely means either a small value capacitor or even just getting close with a piece of wire leading to the counter. This depends on the quality of the counter, i.e. its sensitivity. You'll have to try it.
