One may have a 2.5mm to 3.5mm stereo audio cable laying around. This, a
couple of jumper wires and a spare Arduino Uno are sufficient to make programming cable for a Baofeng UV-5RV2+ radio! Could work with other radios too!

Baofeng UV5R Variants¶ The Baofeng UV-5R is the basis for many other models. Any vendor that purchases a large quantity of radios can have a private label (and in some cases, firmware version) applied to the radio. There is, in most cases, almost no actual difference between the variants, which is very confusing for customers.
- Keypad Programming the BaoFeng UV-5R. The BaoFeng radios are great and are available at a great price. They offer amazing frequency coverage: 2 meter, 70 cm, FRS, GMRS, MURS, Public service Frequencies, NOAA weather frequencies, Marine VHF. Every prepper should have a hand held radio, and the BaoFeng is a good choice for those looking to get.

'Programming' the radio means we'll upload a list of channels (radio stations) we want to listen or transmit to. These stations may have specific settings (offset frequency, tone, etc.), so programming makes it easier to use the radio.
Components needed:
- Stereo cable with 2.5mm to 3.5mm plugs - 1x
- Jumper wires - 3x
- Arduino Uno - 1x
Tools needed: wire cutters, soldering iron, solder, heat-shrink tubing.
Software used: MS Windows, CHIRP, Arduino USB drivers.

Important Note: we're not actually using the ATMEL MCU, but rather the IC, that allows USB to TTL UART communication, found on Arduino Uno boards.
We'll be using a Windows machine, but I'm sure it would work the same way on GNU/Linux or MacOS.
This tutorial is inspired by miklor's tutorial on making your own programming cable. I only realized that an Arduino board can be used instead of the IC he used.

Baofeng Uv 5rv2+ Programming Manual
I bought my Baofeng UV-82C a few months ago and have yet to really use it in the field until this past weekend. Now I know this is a cheapy radio, I bought it knowing that, but I found that other radios near me were picking up transmissions that my radio wasn't, especially our Kenwood TK-2170 radios. I'm not sure if there is anything I can do to improve the sensitivity of the Baofeng, either with settings or maybe a better antenna. I'm using this for search and rescue and our frequencies are all in the VHF commercial band. I have seen some supposedly better antennas but they are all listed for amateur radio frequencies with no data on how well they are in the commercial frequencies. To my understanding, the higher the gain, generally the narrower the bandwidth of the antenna, is that not true? Is poor sensitivity going to be the 'price I pay' for using a cheapy radio?
