I am looking for some better firmware for my S10. I found S12 firmware that got rid of freezing channels on 83w. Has anyone used newer firmware for this that allows you to edit radio channels? This firmware I have: 11-12-10 also lets me record 2 channels in transponder while watching the 3rd. I was thinking maybe this version has been improved but was not sure where to look since this receiver has been swept under the rug which is a drag because it works perfect now.
