President JFK ASC module wiring
Hi friends, HNY!
Just got a JFK in where the ASC is not working. Preowner has activated Roger Beep at the Power adjustment. If Roger Beep is enabled, squelch does not work. So i am looking for schematic for the Uniden PA-338AC JFK with ASC.
Thanks and 73s,
Ralf

Re: President JFK ASC module wiring
The wire colours seem to be different here. What a mess...
ASC wiring here:
Orange and yellow are not used in mine. Brown and black are grounded together to volume switch. Green goes to the pull switch. Red goes to 8v, blue to a resistor to PCB.

Re: President JFK ASC module wiring
Many thanks Claude! The wireing looks good so far. A picture from the soldering side would be great. I only see one from the JFK Classic without ASC. In mine there are a red and orange wire soldered together to one solder point.

Perfect Claude!
But it looks like mine. Can not see any difference in the section where both cables are soldered together. Hmmm...so i think the magic is the pull switch.

Re: President JFK ASC module wiring
Fixed...i removed the ASC module as i did not found the fault. Resoldered the tracks and squelch wire. Finally i removed the ASC Stickers and added a 1000uf capacitor for better voltage filtering. Now it is a JFK without ASC and working fine. Roger Beep and Squelch now working as it should. Thanks for your help my friend Claude.

Re: President JFK ASC module wiring
Hi guys, i have a ASC JFK here & the blue wired from it with the resistor has come loose & i need to know where it fixes to so that i can resolder it back in to position.
I can see by the pictures on here it attaches somewhere near the front end of the pcb near the oblong black 455khz ceramic filter, but i cannot see exactly where it attaches.

Soldered on the top end of the resistor.

Re: President JFK ASC module wiring
Hi,sorry for the delay in me replying & thank you for the pictures, yes i realised the blue wire attached to the resistor, i just wanted to know where the resistor soldered to? by the looks of it to the resistor next to D5.
Best 73, Shaun
