[Elecraft] SignalLink USB

[Joe Subich, W4TV]

In general the modifications documented on the several web pages
are sufficient.  However, improving the power supply bypassing
and decoupling noise sources will also help the noise floor.

The big problem that none of the modifications address is the need
to run the Windows (digital) output at 100% in order for the VOX
to trigger properly.  Unfortunately, the PCM29xx series USB CODEC
gets a little dirty at max output and with the unstable reference
to the op amps, the transmit distortion is only compounded *before*
the TX level control.
