Doe s anyone happen to know how you get a Baofeng dual band analogue/digital radio to transmit on the VFO frequency?
With most radios this is kind of a basic feature but not here it seems.

I thought getting it to use English was the main problem as they didn't think through how hard that is when in Chinese mode.

But it just keeps saying "Tx fail   only rx" whatever the frequency set.

I didn't know Baofeng made a digital radio. What's the model number?

Does it refuse to transmit on both analogue and digital or digital only?

The clue is in the title 8-) and I think Baofeng makes a number of digital models (DMR).
Unlike some it does need setting up for digital transmission, but for analogue you can work it via the keypad, which is fine apart from not working.
I don't have the programming connector for it so not sure what to do about that (in the next five minutes).

Typical modern radio. I hate them. The newer they are the worse they get. I wonder if the manufacturers ever try using them?

Ah yes, I should have read the subject rather than the email body.

Not much out there on the web but you'll have tried that first.


My TYT radio expects transmit and receive frequencies for each channel. Maybe this is the same.  I suspect that if you're not programming it via software then you might be missing the tx frequency.

Hi George

Is this the same as the DM-1801? - that is what it tries to
point me to if I Google BF-1801.

The only thing that comes to mind is have you got it in
repeater mode ( + or - shift)? I have encountered radios
that have a very large default frequency offset (999MHz)
so when you transmit with a shift selected it goes out
of band.

The offset will be a menu item.

Also it may have Tx inhibit set - another menu item probably.

If it is the same as the DM-1801 then it can be flashed
with a version of the OpenGD77 firmware, which makes it
a much more amateur friendly radio.

To Min, it looks like CHIRP does not support it.
To Denis, I have no idea about the relationship to DM1801 and I see worrying notes on the OpenGD77 suggesting that Baofeng may have made massive internal changes to one of the 1801 models (which must violate EU CE marking). Indeed I do not see any indication that 1801 is supprted by GD77 but maybe I am not surprised as all the hacked open software systems (e.g. OpenWRT) seem to only support models of things that you either can't get or don't want and most certainly not something you already have.

This device was an impulse(cheap) rally purchase from a guy who I think had been imnporting them in bulk and programming them for PMR use, so was brand new but programmed by him so presents a bit like other PMR sets that have been hacked for amateur use. So I think it knows all the repeaters for example and probably works them. The problem is that half the documented menus have been supressed so I cannot tell why the VFO mode does not work but my guess is that it is deliberate. Obviously for DMR use it needs the DMR info so I need to find out how to program it and so far it is not looking good.
