when i was testing a ham radio for a science fair project it showed the numbers 2450 and then turned off.how am i now suppose to to test it now?

Sorry I don't really remeber right now but when I get home I can double check for you.

how can it display 4 digits ? to the left of the decimal point ?? if it is showing something as this then it is not working and should be sent back to the factory - first you can try changing out the battery

I've only needed to use the instrument a few times, and don't have an answer.

Most HAM equipment will be drawing only about 5A-10A MAX> The exception would be the radios, which typically draw 20-25A--depending on what you are running. Therefore, I just get the 30A variety, and they cover anything I might use them for.

Be sure you and the person on other radio are holding the radios perfectly straight up and down, antennae up. It has been proven that when held at even a slight angle as in the natural way it lays in the hand frequency range is greatly reduced. It convinced me.

I've looked at the unit itself. No frequency listing is published anywhere on it. Could be 900 Mhz, could be 2.4 Ghz, no way to know.

If you were a legally licensed Ham, you wouldn't be asking this question. This radio is not for you. Get a Ham license first or get a CB or FRS radio instead.

First, check to make sure that you didn't accidentally set the Menu/Lock key. If that is not the problem, you can contact Baofeng at: Baofeng@263.net. Tom, Licensed Amateur Radio Operator

Actually very good question. I got two radios, one UV-5R+ and one UV-5R. The UV-5R+ is version BFB293; the UV-5R is version BFB295. Seems like the older radio as the latest firmware...To check the firmware on your radio: turn it off; press 3 and hold while turning it on. Wait 2 seconds and you will see the radio firmware as BFB***.

With the radio off press and hold the 12/24 button. It may not change, but push it again. My radio required two push and holds.

Good evening could be few things one being the batteries in the transmitter are weak, depending the frequency your boat is running there could be interference jaming the signal which is a good method to turn on transmitter than turn on your boat thus turning on the receiver. This boat also uses the boats battery to power the receiver which in some other RCs the receiver has a stand alone power supply and finally could be a defective receiver yet most likely you shouldnt get any response. Another thing is to check your antenna wire making sure its connected and not tampered damaged with. I actually have two EP777 one 27mhz and one 49mhz ive easily gotten range distance of 200ft being im retired disabled vet. I not willing or able to try further test the full 300ft range in case id have to go retrieve it.

Same problem with aircraft batteries. I tried setting it at a low CCA battery setting to see what would happen and got a reading. I have no way to know if that result is accurate. The thing is designed around inputting the CCA to do the test, so I guess it might not be the answer for you. You might want to consider a carbon pile style tester.

I don't know the number, but be sure to go into Auto Clock Set and turn it off. It doesn't matter if you've selected Manual Set from the main menu; you have to also turn off Auto inside its own menu. Which is a little ridiculous, but... It worked for me. My clock has run perfectly ever since.

I am not sure but I believe it is the range of the unit. Give Vello a call, or send them an email, I did. Also they use a different RF which gives them that range.

OK here we go.. ill make it easy as poseble #1 google KB6NU ham radio blog and download the pdf file for tech this has all the questions and answers in the question pool that you will be asked at the session you will be asked a 35 question test 26 to pass go to google and type in ( ham test your county or near by county ) and it should come up with test sites for that area..also you can google sample test for tech lisense by typing in ( tech test or ham test any questions let me know GOOD LUCK

Possibly, usually the SWR meter doesn't distinguish between (doesn't care about) antenna types, it only provides information based on the antenna you're attached to, the length of your coax or feed, your frequency, and power. Look up the manufacturer website and check to see if your meter covers the 2M/70CM range. This antenna is 'cut' to the rough center of those bands.

Hi Connie. That's not going to happenBaofengs only put out about 4 1/2 wattsThe only way your going to talk to your friends is thru a repeater. Simplex is onlyGood for about 5 to 6 miles. Hope this helped you. I have four of them and been a ham for 27 yrsHave fun

If you left the radio on, then after redharging it will still be. However, the radio does not 'remember' or store which station you had it on. Instead, it will start at 88 mHz (the bottom of the scale).

Like the others indicated, there is a delay when you first apply power to it and it's dark enough for it to switch on. Put a piece of black tape over the photo cell, turn on the light switch, and wait a few minutes. If it doesn't go on, you could remove it and test it with an ohmmeter. With the black tape over the photo cell, the meter should read close to zero. With the tape removed, the meter should show a high resistance.
