Review on BTECH AMP-U25D Amplifier: Boost Your Handheld Radio Performance with DMR Support, UHF Frequency Range, and Multiple Compatible Brands by Muleme Anderson

Review updated 10/04/19 Okay, today we tested the replacement amp. And it put out 37 watts connected to a UV-5R radio. Now this is acceptable compared to the first. You should check these walkie talkies and amos when you get them. This year I had 4 units of different models and they were all bad. Two BF-8HPs, one of those Amos and one of the 50x2 Handys. Original review: What a piece of junk. I hooked up a UV-5R which puts out just under 4W and an SWR of 1.1 at the output of the amp, I only have 25.7W and an SWR of 1.08. excellent SWR, poor performance. Plugged in a 6 watt radio and it only puts out 20.6 watts. Yes, it fell at higher power. Another excellent SWR of 1.06. this is 50% of the declared performance. At 6 watts I expect at least 36 watts of output power.
