My MX300 repaired by BEVANS in Feb 2024 just died.
It could be something they need to re-look at or it could be something totally new with the radio, but it's going BACK to Bevans.
Symptoms - seemed to just "go blank" like it slipped out of the pins in the tray. Yes, I did try gently pushing it back in and that worked a time or two, and then it didn't, telling me it is some sort of power source issue. We will see.
I called the shop chief, Tom, and he was very good about it being only 2 weeks past the 90-Day Warranty. I asked about it and he said they would still honor it, which was very gracious for the $650 fee I paid to have it refurbished in Feb, just 3.5 months ago.
So, thankfully, I have a THIRD radio that went into the panel (and worked) so it's the radio and not the tray or the comm system.
I am patient and that is why I keep THREE radios so I can keep rotating them when they fail (until they fail for good).
For the $650 fee every 10 years or so (per radio), it is well worth staying on this course and not investing in a $4-5,000 radio (each) just to talk while flying VFR in VMC. If I were doing more, like most of you, I would consider some massive glass panel upgrade, but for me this makes more practical sense...more to follow on the radio saga as it goes on!
