Mars Cap Yaesu FT-857D 

Here is a quick video clip of the Mars Cap for the Yaesu FT-857D. I took the modification information from the internet doing a google search. Please do your own research and be very careful when soldering to avoid any possible damage to the main board when performing the mod. If you don’t feel comfortable or have the right soldering equipment, have someone technically capable to do the work. Be well and stay safe. Best 73,
