Building the VA3TO EchoLink Board

My VA3TO kit arrived Thursday, and I began building it yesterday. The layout is very professionally done, and the instructions are well-written. I hope to finish building it today.

Next, I’ll have to reconfigure my computers. The computer that I want to use for the link is currently being used by my wife for Hotmail. I’ll have to move it downstairs to my shack and put a wireless Ethernet card in it. Another complication is that it’s currently running Linux, so I’ll have to make sure I have a Linux driver for the wireless NIC and then get the EchoLinux software to connect it to EchoLink.

Finally, I’ll have to make up the cables to connect my IC-22U to the board and then the board to the rig. That looks like another $15 and an hour or so of work. With any luck, I’ll have it on the air by next weekend.


  1. I’m looking for a copy of the schematic for an Icom IC-22U. Do you have one?

    I’m sorry I don’t have the schematic, but if I recall correctly, they used to be included in the user manual. That’s available all over the net, including

  3. Did you ever find the IC-22U schematic?

    • Dan KB6NU says:

      Unfortunately, it doesn’t look like the schematic is available on the ICOM Japan or ICOM America websites. Maybe if you contacted them directly, they could make a photocopy for you. Another idea would be to contact one of the ICOM authorized service centers.
