Customer Testimonials

Testimonials straight from Amazon, AliExpress, and Kd1mu-radio reviews.

“A lot of power that just fits in a manpack radio bag. Stumbled on to this battery while doing an exhaustive search for a battery to fit in a manpack I was building. This came highly recommended and was a snug fit. So far it’s performing great. A much better price than other less powerful solutions that I was considering.”

L. Fairall

Amazon LiFePO4 Buyer

“I’m a ham radio operator and use LiFePo 4s exclusively. Other purposes include camping applications – recharging phones and other battery-operated items. Add up all your mAH needs, you’ll get plenty of charges off these. And they’re affordable.”

(DM-4R) A MUST TO HAVE Radio I do recommend it. THE BEST DMR and economic Radio It has to stay in the market ! Everything IS THE BEST. Lots of features available.”

“Nice Radio for the Money had appears it has Auto Talker Alias that works !! For the Money this is a very decent radio, software was simple I actually am really impressed.”





Joe Augustine

Amazon DM-4R Buyer

“I found this to be an excellent little radio; sound quality and build is very good. The CPS software was a pleasure to use by far the easiest radio to program. If you are familiar with the DMR structure you will have no problem. If you are not then you will struggle, and the struggle is the same with ALL DMR radios. Go slow and learn the DMR structure and this will make you a fine radio.73”

David Smith

Amazon DM-4R Buyer

“I would not call this an entry-level radio. It does have a few quirks that could scare away newcomers. The biggest problem people have getting into DMR is learning how to program the radio. This is a problem with *ALL* DMR Radios!
I have several similar radios and I can tell you this one is the best value for the money on the market right now.”

Amazon DM-4R Buyer

    I drilled a 1 inch hole through what appears to be 1 to 2 inches of ceramic flue. This is an old incinerator flue that hasn’t been used for 40 or so years and we use it as a cable shaft. I drilled a 1 inch hole to accommodate the PL259 already on the…

    Value-add Our Business Strategy

    I get asked now and then about the differences between my DMR radio and the one sold by the manufacturer. In many cases, the questions imply that I am bulk buying cheap radios and selling them at a big discount. First of all, let’s be clear, you don’t make money competing with the sellers…
