- I've built an interface between my computer sound card and the Accessory jack on my Pegasus. This seems to work fine. I'm attempting to add PTT control via a computer serial port. I've tried two diff

- You should be able to implement your control interface using an optical isolator. This eliminates the need for a common ground. Basically you have a led that is turned on/off and a photo transistor t

- I am using the digipan interface on my Pegasus now. It has a transformer for the audio and a optical isolator for the PTT. That makes sure that no AC gets into the input. Here is a link: http://membe

- An update on my ground loop problem on my Pegasus / computer interface: Based on a suggestion from the group (thanks, K9PH), I grounded my computer chassis to my station ground. That seems to have cl
