Can you link the videos you are watching? It sounds like you are trying to program HAM repeaters. All GMRS repeater pairs are +5 MHz (462.675 becomes 467.675) For local help, reach out to these guys, they run on your local repeaters https://www.facebook.com/groups/3954761801245336/

If you are using a UV-5G, you dont need to use the offset. Step by step: Go to a channel that says REPTR and an number. Press "Menu", Press the Up arrow until you get to "T-DCS" or "T-CTCS" Press "Menu" Use the Up or Down arrow until you find the number that corresponds to the tone e.g. 141.3 or 156.7 etc Press "Menu" Now do the same thing for "R-DCS" or "R-CTCS" Press "ecs" and key up

When you get the cable make sure install the driver for it. https://www.radioddity.com/collections/accessories-programming-cable/products/baofeng-usb-programming-cable

If you want to program channels 31-128 to transmit on GMRS, you'll have to use chirp.

On the uv5g you just go to the channel of the repeater you want to hit. Then you go to the menu, T-dcs or t-CTCS enter the menu and select what ever tone is desired. or use chirp

Baofeng UV-5X Firmware Update Guide_20210308.pdf Read this first. This update was to correct a CTCS and narrow band issue the first few runs of UV5x or G radios shipped with. If your radio out of the box does not have CTCS tones on the channel and is not on narrow band, you already have this firmware.

Found the files Baofeng_UV-5X_Firmware_V1.9_CPS_V2.0_Update_20210309.zip

Trying to find the download file. I can remember if it is part of the new CPS or a standalone file. I’ll have to check my desktop this evening.

No, it won’t. I think you can find directions to the firmware update here https://www.miklor.com/COM/Review_UV5X.php

When you have the cable plugged in, you can go into the control panel, the. Device manager to see what COM port the cable is plugged into. In chirp, you select the COM port when you choose the make and model to read/write from. You want to choose Radioddity UV5G. There may also be a firmware update you need. Most new radios should already have it.

Make sure you have the cable driver installed. Try selecting different COM ports and make the Radioddity UV5G selection.

Keep in mind, things like industrial zones, heavy transmission lines, forests (especially after rain events) and built up areas can mess with UHF propagation. I cant talk with my wife between our house and an old employer due to the number of steel buildings at the old job site. I cant talk with family 8 miles away because their house is surrounded by transmission lines. I could however hit the local repeater and talk with them.

I'm in a fairly flat part of east Texas. With an antenna at 30' I can do about 10-11 miles through the 90' pines to another user who also has an antenna at about 30'. Ive done as much as 75 miles on a 5w and yagi. Its mostly about height. If you can get your family to get antennas ( ED Fong 5dB antennas will be cost effective) mounted at or above the ridge line of the their houses and get some decent cable (LMR or KMR 400) you'll be in business. You could also try some of the 17 ft long 7-9dB dual band antennas. In flat areas higher gain antennas will do better. Also use a RF line of sight tool to check between stations. If you want to get a little further in the weeds, you can use Radio Mobile Online to map you coverage.

I've hit repeaters about 45 miles out on my car mobile. I had the high ground and the repeater is on a tall commercial tower.

Nope, Both RX and TX. They are only RX if you program thru the keypad. My pair only have the updated firmware installed, but no "open mods". The popular method to open the UV5R does not work on the UV5G.

I can get 10 miles on my base station on simplex. Roll up jpole at 30ft to another antenna at 30 ft.

You have to use the radioditty uv-5x or G selection in chirp. In chirp you can program any of the channels 31-120 to gmrs frequencies, repeater or otherwise. I have a pair of UV5Gs

Also check you local ham groups. like these guys (http://ccdxarc.org/). They are local and will be easier to contact than random gmrs forum members.

What specific questions about setting it up do you have? Do you have an antenna for it? How are you powering the radio ( car install vs base install)?

Here is the model put together in EZNEC. I found a yagi template an put in my dimensions. Not sure how to put hair pin matches in. Here are the measurements from https://sites.google.com/view/kn9b/yagi: YAGI Antenna Solution Reflector Element; Length = 12.84 In, Position on Boom = 0.00 In DP/Driven Element; Length = 12.40 In, Position on Boom = 4.02 In Director Number 1; Length = 11.00 In, Position on Boom = 9.21 In Director Number 2; Length = 10.92 In, Position on Boom = 14.40 In Director Number 3; Length = 10.88 In, Position on Boom = 19.58 In Key Parameters Gain = 8.0 dB 3 dB Beamwidth = 72 ° One Wavelength = 25.94 In Freq = 465.000 MHz # Elements = 5 Length Units = In

Ok. I run the antenna on my van and haven't had any issues with it hitting my local repeaters. I feed the UT72G from a 5w Uv5G and battery eliminator. Any other data I could provide to improve you model? Im trying to learn EZENC.

I have one (UT-72G) I can sweep with my nanoVNA when I get home if y'all want.

Some one has a murs simplex repeater set up on that channel. It wont be listed anywhere.

I’ve done a 75 mile repeater hit with my 5r using a junkyard yagi while standing on my roof. Current is same as the old atm. UV5R and 5G

what do the graphs look like when you calibrate the device?
