RADTEL RT470tx FIRMWARE UPGRADE - 2024 V 2.13a

[@geoffreyrandall3459]

Just had a 470x from Amazon, the frequency range was locked 144 to 146 etc and would not let me access the airband. Fixed the frequency range by updating the firmware but not the access to the airband. Found by holding down the ptt button and button 8, then switching on the screen shows the message expand. The airband is now accessible.

@HamTechRadioScannerDrones , QUESTION-1 ... Can i also do this for the 470X ? (which seems to be the latest type and currently sold most) ...2) QUESTION-2: What does this upgrade change or improve ? ... ADDITIONAL REMARKS: There's a few bugs/problems in the 470X (and probably other variations) ... A: In urban areas there's RF overload from out of band reception, mainly from FM-broadcast causing deafening/degrading on VHF & VHF ... and B: Squelch does not operate well on weak but strong enough and very intelligeable signals that should open the squelch but dont ... The lowest value of 1 is not low enough ... so we miss signals both when we remain on 1 channel or in (any) scanning mode ... we can check this by forcing the squelch to open and hear that there is a signal indeed but the squrelch didn't open .... this is a a problem with the Squelch ATTACK TIME being to long before it reacts ... C: The squelch-tail is bad ...we have a long "kercccchenk" this is a problem with the squelch DECAY-TIME being to long ... It is bad design of the squelch-circuit which is probably based on noise instead of a real carrier-detection (COR) ... Best to solve this would be to have 2 separate settings where SQ-attack and SQ-delay can be set in the menu (in milliSeconds) ...or do it in hardware by changing values of some resistors or capacitors.

Hi all good questions I loaded formware 213a

[@Vlrych4Tube]

yes, it does work for 470x

[@reloader7sixtwo]

I see they have some new firmware out for the 470 series of radios, 40-6) V2.13C Adds AM/FM modulation switch from 18m - 1000Mhz. I might give it a try in the morning to see what it does.

[@manshster]

Does the update actually expand the frequency range ? And the expansion rx or rx/tx ?

[@user-sq8xt9gk7u]

I just got the latest version hardware and firmware from factory. It came with Tx 136-640 Mhz and also between 800-999Mhz. And new 8.33kHz spacing for receiving airband.

[@manshster]

​@@user-sq8xt9gk7u i done the update aswell , now the problem i have is the squlesh tail end how to remove it or minimise it on rx from other radios

[@chrissewell1608]

​@@manshsterMy original version ".12" already has that. It may just be a setting in the radio, like squelch tail elimination "STE"???

[@manshster]

Unfortunately it doesn't have that option​@@chrissewell1608

[@Bistiboj]

As far as I can tell, the only thing that this firmware changes is the display font.

[@HamTechRadioScannerDrones]

Agree

[@tiredofeverythingnew]

How to do it if I'm on a Mac Computer?

[@HamTechRadioScannerDrones]

U can't unless you use Parallels

[@jonscharbrough3438]

Where do you find the bootloader program? I have thge 40-6 ) V2.13C Firmware compatible with 470X/470/470L( Add AM/FM modulation switch from 18m-1000mhz (data 20240425) file downloaded, but I can't find the bootloader.exe program to install it.

[@PhDude]

The bootloader is part of the firmware download. Extract the entire RAR and it will be there.

[@JordansElevatedExperiances]

Yeah I was going to ask same question but when I unzip the folder it just gives me the setup.exe and nothing else ?

[@guidelineuk4876]

It's not letting me open the bootloader .. dam computers lol

[@HamTechRadioScannerDrones]

Connect the radio
