Guest Mr Questions Posted March 22 Report Share Posted March 22 Anyone have any experience with this HT amplifier? https://www.aliexpress.us/item/3256801506422672.html?gatewayAdapt=glo2usa4itemAdapt Looks like it would be good for 440/Gmrs.

WRYZ926 Posted March 22 Report Share Posted March 22 You would be better off getting the BTech AMP-U25 amplifier from Amazon. Easier to return if it doesn't work and it will have better customer service through BTech. And it will keep you at the legal 50 watt limit for GMRS.

Bottom right corner of photo. https://forums.mygmrs.com/gallery/image/415-amplifiersjpeg/?context=new The power output falls off outside of the Ham band. For example the DC current input at 13.8VDC with 4 watts of RF input was about 5 amps. At the GMRS frequencies it dropped to around 3 amps. I need to put it on my Bird watt meter and get a power measurement now that I got some higher power UHF slugs for it. I'm guessing I'm only getting MAYBE 20 to 30 watts at most out of it on GMRS frequencies. https://forums.mygmrs.com/gallery/image/321-bird-43-wattmeter/ WRYZ926 1 Quote Link to comment Share on other sites More sharing options...
WRYZ926 Posted March 22 Report Share Posted March 22 @Lscott That's good information for those considering the BTech amp. 20 or 30 watts is still better than 5 watts when using a decent base or mobile antenna. Quote Link to comment Share on other sites More sharing options...
WRXB215 Posted March 22 Report Share Posted March 22 Not sure what it's like trying to do a return but it's cheaper directly from BTech. Quote Link to comment Share on other sites More sharing options...

Yup, just don't expect to get the full boogie out of it. Quote Link to comment Share on other sites More sharing options...
