TidRadio H3 Firmware update UNLOCKS 18MHz-49MHz 

Using the USB-C does indeed work fine for firmware updates. Also, check menu items 48 (and 52, 53, and 54, for even more spicyness) and it on the radio. The AM receive band is turned off by default (menu 48), and 52-54 allow you to transmit out of band on 220, 300, and 500 MHz if you want.

Thanks for putting this video together. I just upgraded my two TD-H3's that I received a few days ago. I decided to try using a Baofeng Kenwood cable, part number PL2303, and it worked fine on both units and didn't require any additional driver install on Windows 10 Pro. Just had to go to Device Manager to find out which Com Port it was on.

thanks, worked perfectly for my H3, with the included USBA to USBC cable. now have the latest greatest firmware 8)

Good tips. I used the USB-C cable, I held down the middle PTT button. The firmware update 240530 fixed a number of issues, including SCAN on broadcast FM band. 🙂

FYI the newest FW upgrade fixes squelch 100% if you didn't try it yet. Its version 20240530. They add a screen dimmer 5 positions at menu 33 also.

I have found that the squelch tail issue is not resolved. It has “fixed” something with the tail when you transmit from your radio to a repeater, probably something to do with the tones used for closing squelch? However, when monitoring someone else’s traffic on repeaters, you’ll notice that we still get the loud squelch when it closes. Menu option 40 should probably be the option we are messing with to find if it’s fixed or not. I believe menu option 30 would be for simplex.

to be able to use the CB would make that Radio very useful because the fcc allowed FM now in 2021. That will save 11 meters citizens band

Wow. My buddy just dropped me his parts list on his old emergency base station. Drake R-4B/T-4X set up. Full system. Until this video, I wasn't really thinking about adding it to my shack. Unsure why I just thought all these newer HT radios wouldnt be able to recieve that low.

0:05:46 Interesting that it will receive AM for airband but not for the lower bands. I would hope that might be a simple fix for them.

Getting AM to work good is a lot of work. IJV was able to do it with the K5 radios.

brick the radio....? (i ran for the hills )

18Mhz was already available on v240401. Also, I don't know when this bug was introduced to the radio, but try it... Go to any of the Memories, can be Memory 01, check the frequency, go to squelch and set it to one, now the frequency on Memory 01 has changed, either by the amount of your step or by 2.5Khz. Also tail is still not fixed, and the actual menu 40 does nothing.

Really nice. No headaches as I had hehe. By the way... did you managed to receive anything yet on CB ? And yes is true... I wish we could have AM RX too. 73, YO6DXE

It completely got rid of the squelch tail on mine sucks cus now i cant tell if im hitting my portable repeater it hits it but no feed back or curchunk some call it.

My 220 channels disappeared moving to Ver 240530 when I did an upload (read radio) on latest CHIRP Next 20240531. Had to reenter, but all ok now. The TID CPS also fails to show 220 channels even though they exist in the radio.

I need to update mine

Mine says AM on the screen when CB frequencies are keyed in on vfo mode. I am yet to hear any cb traffic but i didnt spend much time on it.

This radio sounds like a UV-K5. I wonder if the memory chip offers larger storage (more memory channels) than the UV-K5.

It really kinda bites my ass that no one is using the FM in the 11 meter band here in the states , especially with all the anytone quad 5 and 6's and president Lincolns everyone is running now . I know , nobody likes Cbers using HAM rigs , but y'all got some damn fine radios out there , you can have your HAM bands but get used to sharing the equipment . If you ever wanted to test the receive on 11m I turn my radio on at 9am est M-F 27.555 , Kilo27 Western Pa .

I really wanted this radio, I really wanted to like this radio but, I ordered one with a second battery that promptly shorted out, once I charged it. dead... day number two, ( after a few good QSO's) I noticed no power output - zero... after charging it on its cradle .... I'm wondering if the stun/kill feature somehow engaged ? really weird behavior . my good old UV5R is about 12 years old, and it has never had any issues- ever , and it's so worn out that the keys are worn out- it has been everywhere with me. so this whole thing left a bad taste in my mouth. I don't know if this is a CHIRP issue or a stun/kill (somehow) or charging issue? I'm going to try flashing the firmware - hoping that it solves the TX issues? friends say - so what it's a $30 radio, but so is my old timer.

About the only advantage of the frequency extension is FM receive on 10m. I would not attempt transmitting in the extended range as the radio probably has a real nasty performance outside its original designed bands without the required filters in the PA stage, just like other radios that are modified to work outside their normal VHF and UHF bands. Some even have poor performance before modification. By the way, don't hold your breath on an AM update, without hardware AM detection its complicated and not a lot of use. AM Broadcast, Airbands, and CB receive is about it. 73.

I have read the manual and can't find the way to turn on the meter at the top of the screen. Any idea?

Can can you upgrade the firmware on the the TD-H3 with Chirp or do you need to use the maker's software?

can you please visit the webite again and tell me where I can get the firmware?

Always remember not to turn the radio on until after pressing start on the software.

Here is a question for some one. Can aTD H3 HAVE THE FIRMWARE UPDATED FROM AN Android phone? Also exactly how do you get the firmware update from TID? I have went to the URL thats listed on the card that is included with the radio. And I have been told by Verizon that the number on the card is not active now either so any helpwill be appreciated. I despise windows and hate anything to do with Apple they rip off their own customers!

Question: Does it really receive the Aircraft band in AM? I have the older firmware and it won't do the Aircraft band at all. Comment: It would be nice if Tidradio would allow the firmware hackers access to the firmware so it can be modified to do all kinds of cool things like the UV-K5. Update: I read further down that the new firmware does indeed allow receiving AM Aircraft band, and that AM can be turned on and off in the menu. Now someone needs to add SSB. 😂 I'm going to attempt the firmware update shortly.

i this Firmware update only Possible on Windows? What about MacOS or Linux users???

Would this work on the H8 RADIO

How is the ssb tx audio on 2 meters ?

Not working for me….I don’t see the new firmware from the zip file

My TD H3 is GMRS, chose that download it is a .rar file. Open it, it is a .exe, okay install it. My screen does not appear as yours does. Click Open, walk the path to the folder nothing in there as yours shows. My folder does not contain any of those other files nor folders. Thus, I am now stopped. Uninstalled the downloaded app.

non funziona col mac

10 m is lowest frequency ham band on which FM is permitted. DO NOT Transmit FM below 29 MHz!

@W6IWN , your demo if the squelch tail problem was solved is terrible ... it should be like this: 1) 1st you show us your squelch tail before the update ... 2) Then you show us the squelch tail after the firmware update ... best if you record both so you can show the difference one after the other ... they way you showed in this video is useless ... and we still dont know if it was solved/improved or not ...comon man you can do better ./..then your demo of the 10/11 etc band is useless also ...why not simply add a 3 meters of wire to the antenna and do some tuning over the bands instead of using transmitter 10 cm's away ... i'm sorry this video is a TOTAL FAIL ...comon man you can do better then that.
