I have a pannier rack from the 90s that I made a screw in 1/4 wave 2meter mount. worked pretty well for rail trails but 5watts is hit or miss in the hills of PA. Eventually it would be nice to make a mount for the newer light weight pannier racks, just haven't gotten to it

Having a speaker mic was best for my use but they are not all the same. Under-seat bag was the most concise for the radio itself and a velcro to either belt or handle bar was easy enough. Won't be hearing over highway traffic for sure, but over average road use or rail trails should be fine. Yeasu vx-150 and I can't recall what the mic model is. One good idea on some radios is to get a replacable cell holder. When on a long trip and you run out of energy it is nice to stop at a store and get AA or whichever.
