I discovered some cheap Chinese radios have subpar battery replacers for "mobile' use. The plug in power supply provides enough volts and amps for receiving, but not enough amps for transmitting. After poking around I found some guys using the LM2596 DC-DC buck/boost chip to get enough power to run their HTs in a mobile or base station role. As long as the power source supplying the chip pushes more than 1.5Amps the HT will transmit. I set my chip for 8.3V and wired it to female(?) 5.5mm barrel plug for greater flexibility.

Well, after watching a couple of videos on the subject, it turns out the 'hack' for the UV-5R (actually any of the UV-5nn series) actually works and unlocks the frequency restriction on the radio. Now granted, it's only a $30 radio, so no huge loss, but it would be nice to be able to re-lock/restrict/undo the frequency hack. My personal dilemma is the radio belongs to my other half and was purchased specifically to avoid their operating out of band, especially when their primary use of the radio is as a scanner. Worse case scenario I sell it to somebody who wants a hacked radio and I buy another to replace it (FWIW, I'm not big on hacks, just curious). It would be nice to be able to, as noted above, put it back the way it was. It would also be nice if people putting up the unlock videos might also tell you how to revert the radio back, or at least provide a warning that the hack is a one way trip (If that is the case). That said, this was my fault for not asking myself that question before I decided to see if the hack actually worked (stupid stupid stupid). ? Live and learn!

so i'm trying to manually program my local repeater, but it shows a in and out freq, how do i program both on 1 channel? offset and shift i know nothing about, not even sure if it needs that information. the repeater is MT.HOLLY 462.625, also is it UHF OR VHF. i think i'm just missing a simple step but i really don't know.
