Where to find discriminator audio in Vertex FTL

[N3CHU]

Hi all, just trying to find the discriminator audio output point on the Vertex FTL1011 and 7011 radios as I am interfaceing these two radios together as a bidirectional simplex repeater. I have evrything going except the audio . I have the servive manual but the discriminator audio point is not jumping out at me. any help will be appreciated. Thanks. Davie N three CHU

at J1003 pin 4, pin 1 should be at around 8 volts potential. J1003 is the only 6 pin connector on the main RX/TX board.

Another point is on the IF IC, MC3361, pin 9 or on the end of R1039 which is a 8.2 k resistor coming off of PIN 9 of the above IC.

Here's what I use in a repeater Link radios at a repeater site.....


INFO Vertex FTL-7011 UHF

Ground Braid Ground to right of C2058 / Control Board

PTT Output J2006 – pin 1 Control Unit–Solder side (PTT) - Solder to bypass 330 ohm resistor (if present).

Audio Output J2006 - pin 4 Control Unit–Solder side (TX AF)

Audio Input J2001 - pin 3 Control Board (DET IN) Disc audio

COS J2001 - pin 1 Control Board (SQ SIG) **

** Note: Active High No signal 0 V, with signal 5V.
*** Note: With 10 ohm resister to ground.

Dose anyone know of a good spot to get the COR on a 24 channel FTL 7011?
