Hi.
I have a scanner Commtel com115 with motherboard Uniden. I want to connect discriminator. I have found website Discriminator uitgang but I'm not able to find my model. I found few similar scanners eg. Discriminator Output AE65H - COM212 - BC60XLT This motherboard is similar to my. I read if I have MC3361 on board i can connect discriminator output signal.
I opened my scanner and I find MC. I can connect resistor and capacitor to pin 9 but I noticed that i have pin on board called "pt3 discri." You can see it here (on bottom)

Can i use this pin or i should use 9pin on mc3361.
Thanks for all answers and sorry for my bad language and all mistakes.
