Ted (VE3TRQ), I found your posting outlining how to do this very helpful - THANK YOU! But, because most of this is new to me, I have a number of questions. First, the software that I have loaded on my Mac includes dogparkSDR, Fldigi and Loopback. I started through the steps that you outlined and am stuck on step 2 (xDax - where do I get this software) and step 3 (rigcntl - where do I get this software). Also, I'm unclear as to how the software will communicate with the radio - will it require any interface cables or will this all be done wirelessly through dogpark SDR? Thanks for helping!!
