Internal photo?

 

Hello,

Does anyone have, or would be willing to take photos of the internals? I have a PMR-171 (group is new, not active yet), and I'm installing DMR, GPS and Compass modules. I've asked Guohedz for documentation, but they have yet to come through for me.

As these radios are extremely similar, I was hoping maybe someone already had pictures of the internals with the modules in place.?

Thanks!

I have 2 Q900's and a PMR-171.?
The PMR -171 is a Q900V4 inside with only minor changes to the faceplate and of course the chassis and power.?
The GPS (w/GSM) and compass modules are very simple to insert on the internal headers coming off the board.
The DMR module, however, takes some careful soldering of about 30 scallop contacts right on top of the board just 2 centimeters away from the main processor.
I've attached photos for your edification.?
?The middle photo is an angled photo of the GPS module (seen in the left-middle of the photo). Once you open it up it's very?easy?to install.

Hi Damon,

You have the PRM-171 probably closed by now, but I would like to know if the pins from the mic socket on the mainboard go one to one to the mic socket on front. And also wich two pins are not used. The socket on the mainboard and the cable have 8 pins/wires, the mic socket has only 6 pins.
I'm wonderung if the PMR mic (MH-48 clone) could work on the Q900 since it has the same socket on the mainboard. In firmware 3.4.1 I can even find a clear text entry with all variants including PMR-171.

But then it could also be, that the port is disabled when the Q900 is recognized by the firmware. Would be intersting to try though.

Could you post photos of the DMR board up close with details of the components?
 

Would you have more detailed photos of the DMR?

and GPS it can also be easy to put another module in place

More internal photos at the FCC: https://fcc.report/FCC-ID/2BEJV-PMR-171/7101755.pdf

Interesting that the power specs have changed, as I understood it the Q900 ran off a 2 cell lithium batt.

If you ever have this apart again, I would be very interested in the actual weight (as GH have several quite different weights in various places), and weights of parts mic,batt, outer case sleeve, pcbs.

i was about to buy a Q900 with an eye to making a light weight carbon case to replace the aluminium outer sleeve, to make it close to my '817s weight (750g incl batts)
