This is utmost useful content! Used this mod to calm down my newly bought Baofeng PMR (sold as MP25, sticker in battery bay says EP25). 22k resistor did the job. Some technical details: the chip we care about in BF-T1 is LN4890 (1W Differential Audio Power Amplifier). EP25 uses different one labeled BL6281 (1.7 Watt Audio Power Amplifier) but the pinout is the same (pins 4 (-IN) and 5 (VO1) need to be connected with the resistor). I'm so, so happy mod worked. Thank you VERY much!

Hello friends! You don't need to make any hardware modification to fix the problem. Just program radio using CHIRP software. Settings > Basic Settings > Volume Level. Max is 7 i've set it to 5 and now is ok. 73 de Luke SQ9IVD

With a 33k resistor the highest volume is about the same as the lowest volume on a stock BF-T1. I started with 22k, it was a little bit too quiet for me, then I tested 4.7k, even quieter, so lower resistance->quieter

Easier to just put the resistor on the speaker. A resistor kit is pretty cheap and then you have all values to hand.👍😎

Could the same results be achieved if a resistor was placed in series at the speaker? I have done this mod...but have noticed that the battery drains over time while being switched off...i am not sure if the mod causes this...?

@techtinkerin Жыл бұрын
A resistor reduces current flow so would not drain power more, and yes putting it on the speaker does the same, probably easier and less likely to damage the circuit.😎👍

If you've just bought it then I'd suggest sending it back. To be honest, they are so cheap to pick up on their own it's not really worth the time repairing them as they are more or less disposable at the price that you can pick them up for.

Alternatively, what about using a resistor on the speaker wire? That would seem much easier to solder and less chance of goofing up the board and components.

Hi Daniel, The only way to program this radio is via software. You'll need a Baofeng USB lead & the software, ebay is your best bet. But the best software you can get is called Chirp (search 'chirp danplanet' on Google). Its free and easy to work with this Baofeng. Hope that helps. Cheers.

I used Chirp. The last two builds of Chirp were updated to include the Baofeng BF-T1. Just select Boafeng and from the second drop down, select BF-T1. Thats it, no need for extra software.

Also, if you're using the software on a windows machine, you'll need to make sure the driver is installed for the cable. And the correct com port is selected or it won't download at all.

hi, why should i press monitor to hear?
@OntheMicwithMike
@OntheMicwithMike 5 жыл бұрын
Monitor is used to 'open' the squelch control momentarily. This could be for one of two reasons - 1) to set your desired volume and 2) if you're at a bit of a long range away from the person you're trying to hear, you could press 'monitor' to see if you can hear them before messing around with setting the squelch control to open. Hope that helps.

unfortunately not. Frequency range is 400-470mhz but it can also be programmed to work the 144-146mhz as well, as I have some 2M repeaters programmed into it. So no, it won't really work on the aviation band(s). It's also worth a mention, it's FM only.
