Radioddity RADIODDITY DB40_D

[VK2CRB]

HI, not sure if anyone has got this radio.

I have programmed the radio and appears that there are problems in audio and huge backgournd noise, modulation is broken when receiving, only in FM analogue.
I have tried many settings. In DMR appears ok.
I programmed the radio in 145.450 FM simplex and got a friend 32 KM apart to call me. The radio sounded like the signal was very weak and braking up and impossible to discern human voice.
I then swap same antenna and connector, and cable to a Yaesu FT 991A and he was coming in S 9 + 35 dB !!!!!!!!

I have the feeling I will have to return this radio to them.

Anyone has had similar drama/s ?

There were a lot of questions posted to Radioddity's website asking questions about the DB-40 and very few were answered. That's a Red Flag !

I had a radioditty DB25G. That thing had a lot of the same problems. It went back to Amazon. Much happier with my wouxun XS20G. I have a friend that has the 40W that you have. He claims he has had no issues with it other than the meter says it’s pushing 48watts. Not really an issue. He uses his as a base station unit.

Thanks, well the technical support from Radioddity is very good. Replies very fast. They asked me for the code plug and sent it.
Then they send me a new firmware and I put it in.
Now I need to do more tests.
There is an odd situation. If my son calls me simplex in the same FX as it is described in my initial comments (well above all of the rest) it works ok. I tried to use repeater in 170000 - 600 KHZ and had no dramas.
Unless my friend's radio has a tiny deviation and the Yaesu copes but not this one, is very hard without a good spectrum analyzer to discern.
It is still a mystery.
Also, as the radio by default has 2 screens (meaning dual receive) it might do this. What I mean, the TYT MD2400 and Retevis RT 82 handles (same thing, both made by TYT and I have them) also by default the have dual RX but you can shut down the one you are not using.
If there was just the case they might have missed that in the first place and confuses the radio, but then, my son TX with the TYT handy and repeater enters ok.
As William Shakespeare said in Hamlet:" Something smells rotten in the Estate of Denmark.
The real manufacturer is KYDERA. They are the ones. Radioddity like Retevis are sales and marketing. The OEM is someone else.

NEW UPDATE ON THIS RADIO.

The RF output has blown up. YES !, this past Saturday I smelled burning thing.................put the power meter and the output on high is now only 1.54 Watts !!!!!. Disconnect antenna, put the antenna to the output of the Yaesu FT-991A and had 57 watts, so I know that the common denominatot is...........................????????
I have the feeling this radio has not been totally designed well or I got a bad batch.
The technical support that was answering quick..........................appears to have gone Lost in Space.
I paid with Pay Pal, no news till this coming Friday and I will have initiate a claim over Pay Pal.
I would say that no one should buy this product till they get it right.
RF Patriot, just above, yes, the red flags that I have missed.
I am at the moment quite P OFF.
