[Ham-Mac] PSK - Problems with fidigi and signalink USB

[Richard Hemingway]

Hi,

I'm wondering if any of  you have had the problem I am running into. 
I have a MAC PRO computer running fidigi software and hooked to a 
SignaLink USB and the then into my Icom IC-7410 rig.

The problem I have is that when I am just receiving programs, 
something is keying the SL and a Transmit signal of some kind is 
being produced.  The red light blinks off and on the SL and on the 
7410 as well, but no output is detected on the meter. However, it 
does interrupt the signal I am receiving.

It also does the same thing when I am on the CocaModem software. Any ideas??

Thanks in advance.
