There is other software, but none of them are going to solve your problems.? They change some of the operation, or add features that are not there now.? Nothing to solve the calibration, low audio,? and feedback issues you have listed so far.
My recommendation is to put the radio back together and then follow the instructions for calibration from Farhan in this YouTube video:
The BFO calibration page used in the video is here:
If you follow the steps in the video, you should be able to get the ubitx receive function working.
I did not follow all of the mic/audio issues you are having, however the most common is low audio followed by RF feedback through the coiled mic cord back into radio.
There is no easy solution for the low audio other than a new mic or addition of a preamp.
The RF feedback is solved with .01 mF across the lead from the mic to ground inside the ubitx chases and a snap on ferrite over the straight part of the mic cord just before the connector.? I do not have a v6 so can not send you a picture of how and where to add the capacitor.? Hopefully someone on the message board can help with that.
I feel sorry for you that you are having so much trouble with the kit.? I hope you can look at it as an opportunity to learn and a hunt to fix the problems.? For me that has been the most fun that I have gotten from the 3 that I own.
Good luck in the reassembly and calibration.
