NOTES:

1.  The SignaLink™ requires only 6.75 to 15 volts DC at 10 ma (nominal), so it can usually be powered from the Accessory Voltage found on the Mic jack, Data Port, Accessory Port, or rear panel of most radios.

2.  The SignaLink™ is the only sound card interface on the market that does not require you to use one of your computer's serial ports to key the radio.

3.  To use these other units on a computer that does not have a serial port, you will need to purchase a USB to Serial adapter for an additional $25 to $35. 

4.  Receive Audio does not pass through the RIGblaster units, so you must connect a cable directly between the radio's speaker output, and the sound card.  This will result in no isolation between the radio and the computer, and may cause receive problems because of mismatched audio levels.

5.  The SignaLink™ and these other units can operate direct-keyed CW by connecting them to the radio's CW Key jack.
