Micro PA50+ Testing and Firmware Upgrade. 

I recently purchased this PA50+, and it's a really nice little amplifier. I noticed some issues tripping the SWR protection while using FT8 mode. When I received this one, it had firmware version 2.8.6. This is the latest stable version. I saw there was a 2.8.7 Beta version available for testing, so I decided to give it a try. I cut out parts of the video to reduce time. After the 2.8.7 beta firmware update, I haven't seen the issue I saw before. It will take more time to thoroughly test it. If you do this upgrade, do your research, and do so at your own risk.
