Allows you to decode CW, RTTY, PSK31, SSTV, FAX, etc without the need for an external accessory box (rig blaster, etc).
RX volume is taken from the radio at a fixed level - so it is not affected by your front panel volume control.
Supports the ACC-1 Connector on the following radios: 725, 726, 728, 729, 735, 736, 737, 738, 746, 746 PRO, 756, 756 Pro (I, II, III), 761, 765, 775, 781, 7800
The cable is shielded, 6 feet long and has an isolation circuit to decouple your radio and the computer.
Works great, I've used this for years in the ARRL DX CW Contest - I can copy the code but can't write it down at the same time! I use this cable and software for that! I use mostly DXSoft (http://www.dxsoft.com/) software here. I really like CWGet (http://www.dxsoft.com/en/products/cwget/) - its a very good program!!
CW, RTTY, SSTV, FAX and PSK Software is available online http://www.google.com/search?hl=en&q=cw+sstv+fax+psk+rtty
Remote receiver listening can be done thru the internet with this cable - Windows Media Encoder will port your receiver's audio on the net so you can listen at work - http://www.microsoft.com/windows/windowsmedia/forpros/encoder/default.mspx
