5 out of 5 eggs Excellent Product! 05/19/2014

This review is from: 6.5mm Key Port Data Cable USB for Radio Station Reliable Performance

Pros:

Good physical build. High quality chrome quarter inch jack. Unit is based on a CH340 chipset and yes, IT DOES USE A OPTO-ISOLATOR for the keying interface. No shared/unified grounds in this device. Resistance between grounds exceeds 80 Megaohms, the limit of my test equipment. Works great with my Icom IC-7600 and IC-7000 with Ham Radio Deluxe. When properly configured, I don't even need to start HRD, just start DM780 in CW mode and using the COM port configuration menu, set your radio to STRAIGHT KEY and I am able to use the CW modes the way the manufacturer intended, in CW mode!
It does come with a software disc, but not needed with Windows 7 as driver is automatically installed upon insertion. Just look up which com port number was assigned by your PC and point DM780 to that numbered port and VIola! It works perfectly! Bye bye Signalink and their MCW modes, you will not regret this inexpensive purchase! I even bought two.

Cons:

strain relief in quarter inch jack could be more robust.

Other Thoughts:

One may be able to use an adaptor on this device to convert to an acessory jack and use this interface also to act as a RTTY keyer. I have not tried yet, but it should work.
