G5 pin out

I'm trying to figure out the pin outs on the bottom of the G5. Long story short I want to use my amplified charger base as a charger only, and have the audio still come out of the pager. The amplified charger makes a "popping" sound every time the carrier drops off and drives my wife and I insane at night.

Thanks

I know right? the amp is activated by carrier only which is a bad design.
Have you looked into the base manual? I can't right now but maybe there is some interesting info there

So no, the manual does not give information on the pager socket pin-out. I sent Unication support an email asking for perhaps the schematics.
I also need that info. I'm attempting to force the audio amplifier to stay on independently from the carrier. That should theoretically stop the popping. Might be a simple hack... or not.

If you plug in an external speaker, the popping gets really loud. Not pleasant to hear.

I have verified ground, vbat and the charger detect pins. I built my own small drop in charger using those pins. I have not verified the others, but was told by someone at Unication (not Dave) that the pinout is the same.

Good to know. I haven't had a chance to open the base charger/amp from Unication. I want to mod it to stop the audio popping between transmissions.

Just picked up a G5 so I'm very new to these but wondered too how you made a drop in charger. Could you share a few pictures please? VHF signal around here sucks so it would be nice to make something to drop it into and get it on a better VHF antenna without using the amp charger

You could use a VHF antenna made for a Motorola XTS series, in place of the one that came with the pager.

I need to improve the VHF coverage on the pager so if I understand what I have read the antenna connection is only good for the 7/800 band. Looks like if I could connect to the contacts on the bottom it would be for the VHF side. Would be nice to have sitting here on the table because the county VHF system is not good here

You cannot. The antenna on the pager itself is only for the 700/800mhz band, not VHF.
