1.Cross-Band Repeater Function.
Turn on the cross-band repeater function(menu 6). You can choose one-way or two way repeater(menu 34). One way(single) means the repeater's receive and transmit frequencies are specific. The radio will show 162R2375,426T2375. It indicates the repeater only can receive 162.2375,transmit 426.2375. Two way(double) means the repeater's receive and transmit frequencies are random. The radio will show 162*2375,426*2375. It indicates the repeater not only can receive 162.2375,transmit 426.2375, but also can receive 426.2375,transmit 162.2375.
Cross-Band Repeater function also can increase the distance of communication. If you choose two way repeater, it can make the UHF radio communicate with VHF radio. When you turn on the repeater function, you also can set if the radio PTT Transmitting(menu 33) and Speaker(menu 32) is available.
For example:
(1)RT23 radio A: RX 426.2375MHz, Offset: - 264.000MHz
RT23 radio B: RX 426.2375MHz, Offset: - 264.000MHz
RT23 radio C: Repeater RX 162.2375MHz, Offset: + 264.000MHz
Radio A could communicate with Radio B,It also can increase the distance of communication.
(2)RT23 radio A: RX&TX 162.2375MHz
RT23 radio B: RX&TX 426.2375MHz,
RT23 radio C: Two-way Repeater 162.2375MHz, Offset: + 264.000MHz
Radio A could communicate with Radio B
2.Dual Receive
RT23 is not same with other radios. Other radios can "watch" two channels. Mointor two different frequencies(even on different bands (VHF/UHF)) and the radio will monitor both frequencies giving priority to the first station to receive an incoming call. RT23 not only can "watch" both frequencies, but also can receive two incoming calls at the same time. What is more,you can set the volume mode by the menu 35. MAIN indicates the main frequency sound is louder when receiving, SUB is indicates the sub frequency sound is lounder when receiving. OFF indicates both main and sub frequency have same sound.
For example:
RT23 radio A: TX/RX 162.2375MHz,
RT23 radio B: TX/RX 426.2375MHz,
RT23 radio C: Dual Standby 426.2375MHz, 162.2375MHz,
Radio C can receive voice of Radio A&B at the same time.
3.Dual PTT
You can set a Sub-PTT by side key. If so you need not to choose the transmit channel. Push PTT transmit the main-channel, push another side key will transmit the sub-channel. Very convenient.
4.306 Degree Channel Knob
The channel knob can rotate 360 degree. You can operate the menu up and down by this knob. It is very convenient.

Good selectivity, easy keyboard programming and easy software.
German Lopez on Oct 19,2018I received my radio Retevis TR23 I give 9.5 out of 10 because the metro always shows this full signal. The reception is good I hear repeaters of 70, 45, 38 and 25 km. Good selectivity, easy keyboard programming and easy software.cross-band repeater worked very well
hams on Oct 19,2018It’s certainly the cheapest cross-band repeater handheld on the market right now.I have been very happy with this new radio. It works well!!!
Larry W. on Oct 18,2018After getting it programmed and set up, I started using it regularly. So far it has functioned flawlessly. The display has been crisp, and it has sounded great.Outstanding radio
M.T. on Oct 18,2018Outstanding radio I use it for my job it works great you get outstanding customer service when you buy their radiosGreat 2 way radio
Shannon jean Mason on Oct 18,2018This is a great radio and i would tell my friends to buy one . we will be buying another one in a few weeks. If you are interested in a good two way radio this is the one to get .Muy buen radio
Jorgie on Oct 17,2018Exelente radio. Justo lo que necesito. Y el vendedor muy amable y siempre atento a mis dudas. Recomiendo la tienda . GraciasGreat Radio.
Ron on Oct 17,2018Have had this radio for less than a week but have found it to be a great little radio for the price . I am extremely impressed with the performance so far . It is of seemingly good quality construction, has a nice feel, has a nice compact size, seems to be very well constructed . Although I wish it was about 2 inches longer it is about the size of a mobile microphone. Using it on amateur repeater networks mostly . Have found that even with the supplied flexible antenna I am able to communicate with repeaters that are listed as 17 to 25 miles from my current location which is not at any extraordinary elevation . I've also conducted a Symplex conversation on the .70 cm band At 20 miles distance . everyone tells me have a nice clear signal although when using the built-in microphone I have been told that it is better if I speak up although not shout, have also found that the Baufung speaker mic solve this issue again I have been complemented on the clarity. Also impressed that it came with the USB cable for programming and a mini CD of their programming software although understanding from CHiRP they now support the RT 23 .A Great Radio!
Tim Ricke on Oct 17,2018was very pleased with this radio. I found it to be very easy to program, with the cable and free software or manually using the key pad. The menu is very easy to navigate. I have big hands and some handhelds have such small keys they are hard to operate. The keys on the RT 23 are large enough for me to operate without accidentally pushing the wrong key. I have had great results using the radio on local repeaters, have received good signal and audio reports from other stations. The RT 23 with 5 watts of power has a range every bit as good as my much more expensive handheld. A big surprise that I had with this radio is its ability to work as a repeater. I have played with this a little and found that it does work very nicely and could be very useful for emergency and event communication uses. Overall, I was very pleased with the ease of use and functionality of the RT 23. In my opinion the RT 23 would be the top of the line for the price and would highly recommend it for new or older hams who are looking for a great handheld.Nice Radio.
GHJ on Oct 16,2018It seems very well made, looks good and feels good in your hand. Solid. The sound quality from it's speaker is excellent. The FM radio works well and sounds good. I especially like the rotary channel knob versus push buttons to select channels and menu functions. Transmission reports have been good. You can program pretty much anything you want to from the key pad. The included programing software make programming much easier but it is pretty basic. If CHIRP gets around to supporting this radio it will be a big improvement.RT23
Loge Kuma on Nov 16,2015RT23 is one of the affordable and very durable repeater best for hiking , 4x4 convoy + out door activity , and Nina gives the best customer service + support, Cheers K
