Radio Shack used to sell these with a RS box, but labeled Koss on the
phones. I have been using them for years, wore one out. And they sell
replacement pads on their web store (Koss).

If you want to see the computer and the P3 display at the same time you will
need to get two monitors, one for each.
If you want to switch between them, you can do that *IF* the computer is DVI

Removing this part of the circuit will definitely void the warranty. It

important for amplifier stability.

Hi Mart,
you could just connect the last sequencer port (RIG RX/TX) to the PTT input

John,
For connecting ANY radio to HRD (or any other application) for rig
control, You connect the computer serial port TXD to the RXD pin on the
radio, and the RXD of the port to the TXD pin on the radio. Those are
pins 2 and 3. You also must connect RS-232 Signal Ground which is pin 5.
