dnt UHF69 lpd tranceiver: The more power the better.
I found two dnt UHF 69 70cm radios a week ago at a garage sale. The seller didn’t know much of them and sold them both for only two bucks including a Rubik’s cube in an almost mint condition.
Thinking about my 443MHZ PMR and the “hold two buttons” trick while powering on to access factory menu I tried the same here without much success besides annoying the family with a lot of beeps.
A quick google search didn’t give much, besides a TX power mod.
A TX POWER MOD!
That’s better than a factory menu!.
I bumped it from about 400mw to 750 mW.
It now draws about 300 mA and even if that is 125 mA more than before I really think it is well invested.
Open it up and turn the TX power adjustment potentiometer all to the left
