Greetings,
Has anyone come across this “new” variant of the 888s radio? I’ve been looking over the guide(s) on modifying them for use with AllStar and cannot for the life of me figure out where several of the signals can be picked up… Here’s an image of the back of the main board in the radio:
I’ve removed the 5 screws on this board but also cannot figure out how to liberate it from the heatsink/RF shield on the bottom of it. Anyone with some ideas or experience with this variant of the 888? I’m a bit lost. The Crompton guide (http://crompton.com/hamradio/baofeng888/) stops with the 2015 ver7 iteration of this radio. The little header/through holes used in the guides are not present, or I cannot find them. Thanks all!
The only thing about these radios which is good is the price. In RF, audio,
and interface performance they are truly terrible.
I've attempted to get discriminator audio out of them, and it's impossible as
the entire radio from RF input to audio output is on a single chip. This
means you're limited to using a simpleusb to drive them.
That said, yes, they change the boards all the time, and there are about a
dozen different variants of the 888 radio I've seen from different sellers.
But at under 10 USD per radio, even Macklemore can buy two. If during probing
around, you blow it up, toss it and start over with the other one
I've not seen this latest version you describe, but it looks like you may have
to use some wirewrap wire and come off the IC on the component side of the
board directly now. This isn't hard, but will require some skills to solder
to the pins of the SMD parts directly.
Happy probing,

Thanks Ted but I’m not the one who asked the original question. I built my node a long time ago with a cm108 interface. URI works great too I have a few friends who used that and it was very simple to set up thats a great product.
