G5 internal antenna help

[ngawx]

From reading all of this, I ordered my Amplified charger this weekend from East Coast Pagers. I am hoping to see a improvement for the 1 VHF P25 signal that I monitor inside my home (dont ever have a problem with 700/800).

Well thats different.
I have 1 at home and 3 on my desk and none have an antenna connector. Im guessing home brew.

I bought used from a ham on QRZ so I don't know history. I submitted serial number to Unication, said something was irregular, where did you buy it they asked. I answered, but they wouldn't reply.

I really haven't examined it, just figured it is what it is. I'll take a closer look.

Its an interesting concept. I like it actually. Great find you have there.

 

[Synchro39]

yes great find Unication should make one for sure

Are you able to open the unit without damaging it? It would be most interesting to see how it is wired inside. Apparently you have a unique piece of hardware there.

Engineering sample or non-NA market device I'm guessing.

Could you please post a picture of the back of charger

That's exactly right, it has Engineer Sample sticker on the bottom. Never noticed it before. Not home brewed at all, even has antenna symbol silk screened below the BNC.

Think of how valuable this will become if Unication decides not to manufacture it! You may have the only one.

Also, another difference.. There appears to be a second green LED lit. Only one normally lights.

I'm accepting sealed bids and trade offers.

I noticed that also, wonder what it means

 

[Hit_Factor]

Left LED is pager present. Center LED is power present. Right LED is probably alert received, I have alerts disabled and have never seen the LED on. Little bit of a guess on the right LED function.

MY gut tells me the basic charger has the pins in the base to the antenna port on the pager but probably not hooked to anything. Back in the MIII/MIV days I found if I added 2 pins to the standard basic charger base and soldered a BNC connector on it It did the same as the amp charger. We were on lowband at the time and everyone wanted an external antenna. Used to sell them the same day at the radio shop. THink it cost us $5.00 and 15 minutes in parts to add the BNC to the back.

Has anyone looked at a basic drop in charger to see if the pins are in the base ? I'd order one to try but 90 vs 130 is close enough not to worry.
