Hi Greg,

I  soldered resistor leads to the module.  You can then bend the leads
slightly to allow the module to be mounted on a standard proto-boards.  Be
careful the amount of heat that you use as you can damage them.

I am working on a program to setup the frequencies, volume and filtering
from a usb/serial device.  I have also discovered that these modules will
save there frequency/setup information, so once it's programmed, it will
remember the settings when powered up.  I originally thought that this was
not the case with the DRA818u modules.


73,
