Settings for use of a Delta-44 card with Rocky

Rocky Settings Audio Tab:

I/Q Input Device M-Audio Delta 44 1/2
96 kHz if your CPU and PC are up to it.
Left/Right =Q/I
0 Samples
Audio Output Device M-Audio Delta 44 1/2

Rocky Settings Transmit Tab:

Check Transmitter Enabled
I/Q Output Device M-Audio Delta 44 3/4
Adjust I/Q Amplitude for 1 Watt Output. Do not exceed 1 Watt. (This
comes out to 20 Vpp across a 50 Ohm dummy load if you have a scope.) (A
Norcal SMT Dummy Load is a handy thing to have for setting the power
output. It has a detector and calibration chart.)
Paddle/PTT Com 1

The rest is optional.

A handy thing to have is the Delta 44 Interface board which you can
order from Tony. It gets rid of the bulky box, connectors, and cables,
providing instead four standard 3.5mm stereo audio jacks, and fits right
on back of the Delta 44 card audio interface connector. And they are
labeled for what goes where.

Also get the Rocky Serial Interface board to get the PTT out and the CW
paddles in. This is also labeled.
