[WriteLog] USB CW/PTT interface

[k8isk at comcast.net]

Would there be any interest among the Writelog community for a small PC board that would provide the following without using the non-existant serial ports and using standard USB 1.1 or 2.0 ports?

1. Direct control of PTT from either phone or cw via isolated relay contacts.
2. Keyed cw output.
3. Audio isolation for audio from computer to mic input to eliminate ground loops.
4. Capability to have RS232 or TTL output for rig control.
5. Self powered from USB interface.

I have been working on a design for our multi-multi group, K8GP, and have a nice design I am getting prototype boards made for. If there is enough interest, I would get more boards made to lessen the cost for everyone. Completed boards with all components would cost around $50 - $60 assembled.

Please reply direct.
