I purchased two sets of the Baofeng UV-5R handhelds from Amazon for $25 each. Through eBay I also bought two Nagoya UT-72 and two BL-5L high capacity batteries. I spent the last few days following the handheld manual instructions and did an initial three complete charge/discharge cycles on the stock batteries. Today I did my testing. I mounted one of the antennas on the flat roof of my single story house and put the other on the roof of my car. With a frequency of 462.225 dialed in and a transmit power of 5W I drove through my town and had no issues with reception anywhere I went. I headed west on the highway towards the next town over and did comm checks regularly. I was able to clearly hear and be heard even though the landscape is gently rolling hills. As I reached the top of a hill were I could see the next town I then started driving down into the valley and this is where I lost contact. I turned around and headed back and contact was restored as I reached the top of the hill again. According to the measure distance function on Google maps the as the crow flies distance between my house and the lost contact point was 9.88 km. I must admit to being fairly pleased with this. Obviously I would have preferred more but the topography wouldn't allow that. I could easily install a taller antenna at my house to increase the transmit range from it but of course that would be just one direction. I would be able to receive messages further away but I would need to determine a better antenna on the other unit in order to respond. The entire reason I bought the units was to have portable, longish distance comms in my area of operation so based on that I would say I have accomplished my purpose. If you have a similar matching requirement I definitely recommend these radios, especially for the incredibly low cost. The BF-F8HP is in the same family as the units I bought and uses the same accessories but the tx power is 8W so perhaps that may be a consideration for you to get some additional distance. Those radios however are currently $63 each from Baofeng. While browsing through the Baofeng web site I reviewed their latest model the UV-5X3 and saw this cool feature: "The UV-5X3 can respond to remote commands. By remotely sending DTMF tones you can both 'Stun' (Transmit Disable) or 'Kill' (Disables all functions) the UV-5X3. You also can 'Revive' a UV-5X3 from its "stunned" or "killed" state. You can also remotely turn on the microphone through 'Monitor'; or ensure the radio is within range by using 'Inspect' (replies with a confirmation tone when it is within range)." Anyway, I am happy with my purchase and the subsequent test results.
