We recently modified a Yaesu FTM-400XDR transceiver for out-of-band transmit coverage. This will VOID your radio's warranty. This should not be done unless you're experienced with soldering extremely small components as well as having a license and permission to transmit on other parts of the band. Other instances may include GMRS, Public Works, Radio Remote Pickup, etc. ***Each of these services requires its own license and you must adhere to their own rules. Do this at your own risk***. We will not be showing you how to do this, only helping the Memory Error after completion.
1. Copy your data from your radio to an SD Card under the settings menu.
2. Read your data from an SD Card via RT Systems Software, then save to your PC.
3. Remove the appropriate diode
