Debeg 6310

Debeg 6310

It's not too difficult to make the Debeg 6310 marine VHF suited for the recepton of AIS by adding a discriminator output.

Debeg 6310

The receiver IC, a uPC1028, is located on the main circuit board. The easiest way to connect to this IC is on the solder side of the board.

The unfiltered audio on the FM IC can be found on pin 7.

Pin 7 of the uPC1028 contains the baseband audio
The discriminator output

Follow the next steps to make the discriminator output:

  • Connect a 1 k resistor to pin 7 of the uPC1028
  • Connect the positive lead of a 10 uF, 25V electrolytic capacitor to the other lead of the resistor
  • Connect the inner conductor of a piece of shielded wire to the negative lead of the capacitor
  • Connect the braid to a point on the circuit board that connects to ground, e.g. the solder pad marked 'GND'
  • Lead the shielded wire outside the case and finish it with a female cinch connector
the pigtail

I have chosen not to put a chassis socket in the case, but to use a 'pig tail' in stead. If a small hole is drilled below the antenna socket, the shielded wire can be led outside and terminated with a female cinch plug.

Obviously, it is also possible to use a longer cord and use a 3.5 mm plug to connect the signal directly with your PC's line or microphone input.
