Yaesu FC-90 Tuner Firmware Update – Full Test & Real-World Results

https://buymeacoffee.com/kj5exe In this video I put the Yaesu FC-90 remote tuner through its paces to see if the latest firmware update actually fixes the long-standing tuning and memory issues many of us have seen in the field. I start by testing the FC-90 on the old firmware, show where the tuner falls off across the band, then perform a full firmware update and factory reset before re-testing on multiple bands. I also walk through my portable truck-mounted antenna setup for those running similar mobile or field configurations. What’s covered in this video: FC-90 vs FC-80: 10:1 vs 3:1 matching and why I chose the FC-90 My field setup: F-150 truck, 2.5" pipe mount, and 33 ft DX Commander pole Pre-update performance: tuning behavior and where it drops off across the band Step-by-step firmware update using SD card and external power Factory reset procedure Post-update testing on 20m and 40m bands Discussion on memory behavior and why it now works much better Thoughts on the MAT FTX-1F tuner and how this update may have impacted it Key takeaway: After the update, the FC-90 tunes quickly and consistently, with resolved memory issues and much better behavior across the band. If you held onto your FC-80/FC-90 despite early negative reviews, this update may make it worth putting back into your regular kit, especially if you’re running non-resonant antennas in the field.
