Prototype Eqso/Echolink Interface Card

After the assembly and test of the first interface card,
I went on to make this 2nd prototype interface card with
a few more donated parts. 1 of them is an old Modem box.

This is how it looks !




Overall view of the "new" completed unit with the

interface card inside.



Inside view of the 2nd prototype. Notice the 2 LEDs

and the addition of a speaker with an ON/OFF switch.

(for monitoring output from the rig during Gateway use)

  • Bravo! That is a splendid idea with a speaker to monitor the audio coming from the Rig at the same time.

    Just a suggestion, it would be nice also to add in another speaker parellel in line with the sound card output to monitor the audio coming from the Computer.

    Or since it is messy to add in another speaker, why not add a relay switching to share both output junctions to one speaker.

    You might need a variable resistor in series to attenuate the audio level coming from both source into one speaker.

    Just an idea???

    Good work and let me know if you need some one to test the circuit.

  • Seeking opinion... as suggested by a few ham operator... why not 9M2RUK repeater be designated with a RF Gateway to EchoLink and eQSO hosted by two seperate PC Gateway at AliBaba as the QTH command centre?
