    So for a little more information I had to remove the motherboard that was in there.. put everything back together without the motherboard. I am running the SDR off of an external Tower. the the problem is I don't have an external sound card and I had to reinstall everything from scratch for the Genesis power SDR software. I don't have a PCI Express sound card the old motherboard had a PCI Sound Blaster card so I have to use the built-in one. Power SDR doesn't seem to recognize the SI 570 but it does appear to be working the only problem is the LO will chase my tuned frequency.
    I have the SDR using the line in and line out and a mic on mic in but can't get it to work with mic pushing Mox

    Seems my friend found the source on eBay. Really spendy. Mine sorta works now. But getting mirror signals on waterfall
    https://www.ebay.com/itm/SDR-Transc...-PC-SDR-All-modes-6-Khz-ESSB-CB-/133041856993
    In his Ebay listing when you click on more about the description in the second video shows the exact same radio with the exact same glued on paper labels
    This guy used an awful lot of masking tape electric tape and hot glue to be charging $900 for one of these with a pirated copy of Windows 7 installed on there that can't be validated.
    Here's a quick link to the YouTube video

    So anyways the power supply module failed t...the original sound card appears to have failed and cannot be recognized by the motherboard so I'm using the built-in internal one. I have completely went through and redid everything on the radio and installed a new small Slimline power supply out of an old eMachine.
    I'm unable to get it to transmit audio. I can get it to put out a carrier but I cannot seem to get a microphone input to work with the onboard sound card

    You might try one of the USB dongle sound cards. Many have good success with them.

    Yeah I was wondering about that because I figure I could use a separate sound card just for the mic input

    Many people use them. I have not tried, myself.
    Have you checked to be sure all of the drivers are correct?

    The Avala 01 basic design was done by a guy in europe. Michael Frias sold them as kits and made cases for them. The touchscreen feature is something I've not seen. If you contact Michael it's likely he will be helpful.
