The Ancient Modulators Club, Echo Link Remote Base Radio Interface system, is located at the QTH of KØRWU, Paul Schlipp, in Arnold, MO.

This picture shows the Yaesu FT-51ØØ radio, and modified Astron power supply, for use as the Echo Link Remote Base Station.

The Yaesu FT-51ØØ dual band radio was selected because the link could be switched to eather the 2 meter band or the 44Ø mhz band.

The basic system in configured around a interface circuit board sold by WB2REM. I purchased this unit in a kit for the amount of $4Ø with $6 shipping.

In order to make a compact interface system, I mounted the interface board, and audio circuits, inside of a Astron 12 amp. power supply.

I mounted a Yaesu FT-51ØØ radio to the power supply to make the link system compact.

The only cables connected to the radio/power supply, is the antenna, computer serial cable, computer sound card mike line, computer speaker cables, and the computer sound card input cable.

I have installed switches on the power supply to switch the radio speaker, and the computer speakers on or off, and a audio level control to set the audio input level to the radio. Of course, I normally leave the speakers turned off.

The computer is in my basement, on my home network, and is dedicated to the echolink system 24 hours a day.
