[Elecraft] KX3 Computer Interface for digital modes

[k3ndm at comcast.net]

Joe, 
The SignaLink uses the radio's PTT on the mic connector to switch from rx to tx. That is all that is really required. However, it does have a built in sound card that does work better than the one in my laptop. All power is taken from the USB connection to the computer. It's a complete, easy to set up and use package. With the additional sound card, I can do other things. So, I'd say your characterization is a bit off. 

73,

Signalink USB is nothing more than a repackaged $10 USB audio dongle. 
It does not provide any USB to serial functions and no access to TxD, 
RxD, DTR, RTS. Lance specifically needed TxD and RxD for computer 
logging and RTS for advanced PTT. 

The alternative to the WestMountain Radio Nomic is a Buxcomm Rascal 
with a custom serial cable that splits RxD/TxD to the rig and DTR/RTS 
to the Rascal then to the rig.
