Easy to follow. Programmed my radio flawlessly. Thanks, man!

Outstanding video. Thank you for posting.

I am trying to just do Packet, and at 3:51 you are showing VARA and where I live we only have packet. I don't see anything in Winlink Express that looks like what you have. (that sound card)

How did you overcome the common ground issue? When both radio's have a common ground, through the charger when it is hooked up, the transmitter will allways transmit. PTT button, or in this case the charger, connects mic ground to speaker ground.

How did you waterproof the charger USB connections?

Great video.

Did you leave repeater radios in frequency mode, as opposed to channel mode, and does it even matter

My experience with those little solar panel battery banks is that the solar panel is undersized. It takes about a week in bright Florida sunlight for the power bank to go from 20% to full. A little 10 watt panel is a substantial improvement. A 25 watt panel is more of a beefy solution for this application. You will need a controller with the external solar panel. Sometimes that is included with the small panels. Sometimes it is not. Thanks for posting.

I totally understand and it’s definitely educational. I enjoyed your video. I was just wondering if I was missing something. I am actually in the process of putting one together myself.

I don’t understand shy you reverse polarity of the crossover cable? It’s functionally a crossover by connecting between speaker and mike.

Thank you for the great detailed video!

So my question is why two radios why not just purchase a small repeater like a sure com repeater this way it’s all plug-and-play and a lot less wires no need for crossover wire, and then you would only need one antenna or am I missing something but I will say I definitely enjoyed the video and it was very detailed which I appreciate thank you sir

Thank you for another great video.

Tip.......put washers under the back side of your rivits when fastening to plastic.

That solar power bank will NEVER power that repeater. Ask me how I know. I tried the same idea with a meshtastic setup. With a 10ma draw, in the blazing Florida summer sun, the battery bank was empty in three days. Those solar battery banks are a joke. I updated with a 12" 5v solar panel charging a 8000mah 1s RC car battery. This setup actually worked.

Hi, I tried to program various 888s radios but after writing, the radio remains with the channel open and the green LED on... I also tried using the boafeng application... it's always the same

I have some Baofeng 5RM’s 4 have the same version 14 and 2 have version 11. Can I transfer version 14 data to the two version 11’s? Also, is one version blocked? Which is better? Or should I go to Baofeng Website and upgrade the 11’s to version 14 or whichever version is the latest? HELP😮😮😮

Hi, thank you for a great build, I note the file link does not work. Thank you anyway.

@Sgtoscarcolon 4 hours ago Hi, excellent and very well explained. Very useful detailed video. Thanks!!! What were the HT settings? Squelch off/on?

I need some clarification. Help me understand. Why do you need to program any transmit settings in the Receive Radio, as it never transmits, and vice versa on the Transmit Radio?

Two walkie talkies is not a repeater or at least not a good one

please try to use power supply if working good thank you sir

You did a great job that was a so useful video

Thanks. I'm a couple of years behind you on this but appreciate your help catching up. W5XTT tom.

Way back in the late 80's and early 90's my Ham buddies built and operated half a dozen "Repeaters". We NEVER had to use cheap "toys" from Communist China. And a few of these "Genuine" Repeaters are still going strong! Even after a full third of a Century of hard, daily use.

Is that the clear pet lam roll

Hi - How do you set the channel spacing?

The plug to power the radio what is the #s and where can I find it? Hopefully I can find one with other end a USB to then plug into solar bank. Can you tell me where you found and what it's called for the sma and so239(?) Plug mounted to box? Tks

Great video. What did you program in the channel freq, is the 145.030 one that you use the most?

Thank you for sharing this video.

Good Job..... thanks for you ,,, this is A65PP UAE ,,,, 73 brother

Little 20w duplexer

I tried the 720 second and the image came out way too dark. Like it was burnt. Any suggestions

Thanks so much… I would have loved to have seen in the video the CAT control actually controlling the radio. It seems you showed both cables working but not the advantage of one cable over the other. But thank you for taking the time to verify settings. I have the exact setup and just got it working - of course the day BEFORE I watched this video. But this will allow me to go back in and double check my settings. Thnx!!! W5HIM

Greg AI5HV here. I was able to make both the AnyTone 578 audio only cable and the AnyTone 578 CAT and audio cable work. Tests were performed with the following equipment: AnyTone 578UVIIIPro Digirig Rev 1.9 AnyTone 578 audio only cable AnyTone 578 CAT and audio cable Windows 11 laptop With the audio only cable the user MUST do the following: Radio setting changes · Set the squelch to 0: Menu / Settings / 1. Radio Set / Other Func / 6. Ana Sq Level / 1. Ana SQ OFF was set to 1. It will work if there is a lot of background noise that you set the Ana SQ Level to 1. · Change the audio to mic: Menu / Settings / 1. Radio Set / Voice Func / 7. Speaker Mode / 1. Mic Spk was set to 3. Both · Change the mic type from serial to voltage detection for PTT to work: Menu / Settings / 1. Radio Set / 4. Other Func / 28. Hand Type / 2. Volt-Det. (Note: Don’t forget to change it back to 1. Uart-Det for normal hand mic operations.) In WSJTX, PTT works fine with the audio only cable for testing. In VARA FM the PTT setting MUST be as follows (the COM port will vary from one computer to the next depending on what COM port is assigned in Device Manager) PTT Via COM Port is COM3 and PTT Pin RTS With the CAT and audio only cable the user can leave the settings as follows: Radio setting changes · Set the squelch to 0: Menu / Settings / 1. Radio Set / Other Func / 6. Ana Sq Level / 1. Ana SQ OFF was set to 1. It will work if there is a lot of background noise that you set the Ana SQ Level to 1. · Change the audio to mic: Menu / Settings / 1. Radio Set / Voice Func / 7. Speaker Mode / 1. Mic Spk was set to 3. Both (This setting can be left set to Both but the user will hear the data transmit tones on the radio speaker). · Change the mic type from serial to voltage detection for PTT to work: Menu / Settings / 1. Radio Set / 4. Other Func / 28. Hand Type / 1. Uart-Det. DOES NOT NEED TO BE CHANGED. In VARA FM the PTT setting MUST be as follows (the COM port will vary from one computer to the next depending on what COM port is assigned in Device Manager) PTT Via CAT Brand: Anytone Port: COM3 Model: AT-D578UV Bauds: 115200 RTS I even tested unplugging the CAT cable from the Digirig in this configuration and confirmed that PTT DOES NOT WORK without the CAT cable plugged in. In WSJTX, PTT works fine with the audio only cable for testing, but it does not appear to work using the CAT and audio cable. There is no entry to select a radio type of AnyTone 578 within this software. Using the CAT and audio cable appeals to me because I can leave the radio settings alone and not have to change anything.

Why not use the digital caliber?

I like your video. My experience with doing this very sameproject was a jolt to my brain. 3 or 4 trys and i found my sweet spot. Now i did mine for gmrs . I used a much bigger box. I put a 10 ap hour lipo battery in and a bigger solar charger. Now most of the rest isthesame . I did find the charge cables to be a problem . Did away with them that have the chip and lights. Plain jane usb cable and no more issues. Also i used very different antennas . AND THE ANTENNAS wanted to be about 6 to 8 feet part. I will be doing a whole new set in a couple months. I hope that works for how you plan to use it. Oh oh i found that i am getting approximately 10 to 15 miles coveage in a circle around where i set it up depending on weather its an ht or mobile rig . Mobile rgs clearly get better rsults.

you dont need 2 antennas

Thanks Uncle.

My CHIRP program says that there is "No response from radio" after clicking "OK" to "communicate" with it. Do you mind telling me how can I fix that?

Anyone in Washington state that can help me with this

Another great video.

You worked real hard to make that look professional, but you forgot to take off the label that came on the box when you bought it ... nice setup though. I like it.

Only if your cross banding will this be maybe worth while.. for a same band repeater such as gmrs with only 5mhz offset these radios will desense and trip all over each other without a duplexer. Personal experience.. you need at least -80db seperation between that 5mhz spread to be able to use more than a few watts and its input radio be able to hear anything beyond the transmit radio.

power supply? not sure how long 3600mAH batteries will last for on standby, but pre going the whole 9 yards with solar, would battery eliminators connected to a small motorcycle battery be worth doing for a mid term repeater solution?? ""BL-5 Battery Eliminator Replacement for Baofeng UV-5* - pretty sure these have a built in regulator (they're designed to be plugged into car lighter socket) 2 for $20 on Amazon

I had one of those cos-play antennas I bought for UHF CB (477mHZ), "Bingfu Foldable CS Tactical SMA Female Ham Radio Antenna 2-Pack Dual Band VHF UHF 136-520MHz 42.5 inch Antenna" - 2 for $23, what could go wrong? up to 520mhz printed on the base yet it had a SWR of 8 with the whip, base by itself was about 1.2 haha... Be interested to hear what the Arbbree SWR's are?

This is a great video and exactly to the point, however I'm still unclear why I would be doing this. Is it to make sure that all my BF888s radios share the same frequencies for each channel? And you replaced the settings with an existing file; where did you get that file?

Please attach the name of item using,

Nice build watching from Philippines

I like this design! Having the fuse block on the lid right next to the switches and accessories is smart
