Re: HF Coupon for case
That $5 price is after an additional $49.95 purchase. I agree, it is a great little case - I use one to hold a DMR HT, Pi-Star hotspot, USB battery pack for both, and a charger as a mini DMR go-box

I used some PCB for mine. Or you can go to a hardware store and get some aluminum and make a new panel. The steel one is hard to work with. mike AI4NS

Allison, I am basing my report in wa2eby's recommendations. My own measurement lead me to believe that between 25 ma to 150 ma, there is not much of a difference in linearity. The linearity increases
