Radio FYI

[Gunfighter14e2]

Received another shipment of Baofeng radios two weeks ago & yesterday got around to programming them. Some had very odd freqs with Tx & Rx tones or DCS programmed in them but the kicker was a few had, Rx only DCS/tones programmed in. Called to spread the word to other locals & hrs later they were finding radios never powered up they had storied from years back, with the same thing.

Nefarious, no clue, but now everyone is double checking every unit.

I own a couple baofengs but Tx and Rx means nothing to me haha. Are you saying some frequencies don’t work or what should I look for?

Tx= Transmit
Rx= Receive
Any radio programed with a Rx freq only, and that freq requires a Rx DCS/Tone is beyond interesting. That type of programming is used so other people using that freq are never heard, unless they also TX the DCS or tone you have selected. It can also be used for other tasks.

We wiped all the radios clean, even the ones that appeared to be clean & made positively sure only those freqs we use, were what is programmed in them now. Of all the radios we have, over 75% were found with interesting programming. The same odd three freqs with DCS/Tones was in every radio that had programing in them, to include over 30 radios in factory sealed boxes/cases.

I think I understood about half that. Sounds like the pre-programming you found would allow others to use the same frequency (talk amongst themselves and hear me)? Is the solution as simple as removing all frequency presets or is it more involved than that?

Appreciate the info

I have my own "programming" for them.
So the factory settings go away just as soon as I plug into them anyway.
I don't think I've even paid any attention to what they came programmed like.
I'll take a look at a new F8HP I got a few weeks ago that is still "virgin" and see what it's got.

Mostly UV5R's new & old, including the new FCC approved versions as well, a few of the old BF-F9V2's had it as well.. After seeing this I'd not trust any Fengs until wiped clean. None of our Yeasu's had anything added beyond what we installed. We are now checking every digital we have, just to be sure,...

Difference between Chinese and Japanese manufacture, I'd imagine... The 'fengs are cheap, but... yeah....

Back doors can be a game changer, no matter the item cost,... All the Kenwoods and Icoms came up clean.

Is that the invaders frequency set up ready to use out of the box?

Could be, as most of their lower level boots just know how to be bullet magnets. The upper levels have some real interesting comms that are simple and almost jam proof for the most part.
