For use with amateur fm satellites. Further, the transceiver contains a listen-only fm receiver for the fm broadcast band on a dedicated chip. (*) the transceiver is 47x81x23 mm, and weights about 120g (radio with battery and antenna). That’s about the same size as a standard 20 cigarette pack, whic...

You may want to order it with the usb programming cable. The software is a free download. What warranty is offered? If buying directly from hong kong you should get a repair/replacement upon return of the faulty item. You have to pay for the shipping cost for returning the faulty item to hk. Check t...

What are the differences between the uv-3r mk.I, uv- 3r mk.Ii, uv-x4, uv-100 and uv-200? The uv-3r mk.I, uv-100 and uv-200 models are said to be electrically identical, just with a different exterior look and external port. Uv-100 and uv-200 share a compatibility with speaker- mic (409shop item 41-7...

Or cables. A pl-to-sma works too, but it might put too much strain on the antenna connector. Some of the adapters are a tight fit, and it may be necessary to remove a small amount from the case near the led with a hobby knife to get firm seating. Which dual-band antenna can i buy? Not all sma-male a...

● shift value for transmit. Usually 600 khz for 2 meters, 1.6 or 5 mhz for 70 cm. Make sure you are in vfo mode for 2 meters. Display should show no channel number. In case, press/hold u/v key long enough to get there -- it will cycle through memory mode, uhf, vhf. To set the receive frequency, lift...

First, get a list of the repeaters or simplex frequencies you wish to program into the baofeng. In addition, you will need: ● a programming cable - usb connector on one end, the four-conductor plug on the other end. Yaesu programming cords will not work, as the connections are different. ● programmi...

Frequencies (if allowed). When you are done, exit the program and disconnect the cable from the computer and the ht. Please turn the radio off before inserting or removing the programming cable and save yourself the possibility of doing some harm to them. Once basic programming is done with baofeng ...

So, you are waiting for your “r” and programming cable to hit your doormat but you have free time to prepare the memory file? No worries, install the correct software package on your computer, type in all your memories and save to a local file. Once the radio+cable arrives, install proper drivers (f...

Name=0 to name=1 when you reload the uv3r software you can enter the name of the channel (4 characters only) in the last column. The bad news is that it's not yet clear how we should enable the channel name (alpha tag) display on the radio itself; nb: the change in settings.Ini file must be done whe...

Baofeng software uv-[nn] (where [nn] = 3r or x4) has these although listed differently such as duplex/offset as separate entries for rx/tx freq sets. In addition uv-nn includes setting the basic setup items like freq range, scan setups, vco setup for both uhf and vhf vco's (rx freq, tx freq, encode,...

You can save that as the basic setup in chirp. Then you enter your memory frequencies, offsets, tones etc., save that file under an appropriate filename, and then upload to the radio. You now have all of your setup info and basic radio preferences saved along with the memory channel assignments. Thi...

You ought to get a pop-up box from which you can choose the port as something like '/dev/ cu.Usbserial' - this is the port that is hidden until the pl2303 driver is installed; other options for port are bluetooth ports on my setup. Choose vendor as baofeng, model as uv-3r, and hopefully hitting ok w...

This works fine for ubuntu, however in fedora the linux usb serial device has to be made rwc to be operational in wine. To make the linux usb serial device rwc, you could execute "sudo chmod 777 /dev/ttyusb0" in a linux terminal. With debian it works fine with a tty cable and wine ---- both versions...
Page 21: What Does Relaym Do?
What is wide/narrow setting? This setting controls rx bandwidth and fm deviation. These have been measured to be: tx, max deviation wide, +/- 4.8khz tx, max deviation narrow, +/- 2.4khz apparent rx -6db bandwidth wide +/- 8khz apparent rx -6db bandwidth narrow +/- 4khz adjacent channel selectivity m...

Region 2 - americas - and 12.5 khz in iaru region 1 - eu/africa -) and run a memory scan instead. The third option is to set the band limits as per instructions in message number 2968 , but that limits all frequency related programming. This is not an elegant option, a good used scanner works much b...

Chirp is a free cross-platform, cross-radio programming tool. It works on windows and linux (and macosx with a little work). It supports a growing list of radios across several manufacturers and allows transferring of memory contents between them. Mike n4mep tells how: i used chirp to read all my st...

Many uv-3rs users experience a very low power output on the vhf ham band in “low” setting. It has been measured to be at around 100mw at 145 mhz instead of the advertised 1w. This behavior is normal. Sp3swj has found a hardware fix for this - replace inductor l19 with 220nh. This will then give 1.3w...

Increased up to 27k or 33k. For the tone beeps path r10 (100k) can be replaced by 220k or greater. However, the 1750hz tone, which is used for accessing repeaters, is sent via the loudspeaker and picked up by the microphone. If r10 is increased too much the level of this access tone sent by the mic ...

If no fm broadcast can be received, try the procedure described above for looking for cold solder joints. How to extend frequency range? The frequency range of the two bands can be extended using the official programming software and the programming cable. It is a trial and error procedure which mig...

Only one pair of ranges will be written to the radio. Save the settings.Ini file and close the text editor program. Now re-open the uv-3r program. Make sure you are opening the same version of which you have edited the settings file, in case you have several installs on your pc. The new range will b...

Is there a software maintenance mode? As of uv-3r sold until january 2012 (mark i and mark ii) there is no software maintenance mode. If it is there, nobody has figured out how. My uv-3r just completely reset itself. Why? If the frequency on the display was outside the normal range, e.G. 133mhz, whe...

These units can operate on frs/gmrs frequencies. They can probably be configured for fm devition within the allowed limits for these bands. Frs/gmrs radios are required to be fcc type accepted for frs/gmrs use; these are not. Frs radios are prohibited from having detachable antennas (in order to pre...
