We have a customer with a G5 pager in an amplified charger that is having a very strange issue. With the pager in my hand, it will lock on to the nearest site in the next county....they work mutual aid with them. The county is using 800 MHz P25 paging. . So the pager will be locked on the site's control channel, and then I can put it in the charger using the supplied whip antenna and it will remain locked on the CC, but will occasionally go out of range, which is a problem as they want to use it for station alerting. So we installed an antenna on top of the FD, using an automotive 800 antenna on an NMOKUD cable running into the building and to the pager with a short extension added as the 17' isn't quite long enough. Here is the problem. If I connect the outdoor antenna directly to the charger, give the pager a few seconds to scan for towers and it will go out of range and stay out of range. If I disconnect the antenna from the charger and plug it directly into the top of the pager using an SMA to BNC adapter, the pager comes in range and never leaves. Put it back in the charger and put the antenna on the back, Out of range. Put the pager's antenna back on and remove it from the charger, in range....though RSSI is higher. I've checked the cables, I've taken the pager and charger on the roof of the building with a new antenna, cable, etc. and it still goes out of range but only when it's in the charger. We've scanned for any interference and found nothing close. I'm working with Unication, getting logs, updating firmware, etc. and I wanted to see if anyone here could help me out with any suggestions. The site is only 8 miles away, and just for kicks, I put it in my truck and in the charger with a mag mount outside, it was picking up the CC from another site 22 miles away. The site I'm trying to hit, at last PM, produces more power out of the combiners than the one I tested at 22 miles. So I'm at a loss. I was thinking interference, but it only happens in the charger. Out of the charger, the pager stays in range. We've tried 3 pagers, 3 chargers, two antennas, two cables, replaced the connectors. Has anyone ever seen such a thing before?

To anyone looking to acquire commercial radio programming software:
Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.
If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.
To obtain Motorola software see the Sticky in the Motorola forum.
The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.
For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).
This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.
G5 Going out of range in amplified charger

How did you power it in your truck?
There are multiple posts about this happening. I've tried everything suggested in most the posts and still occasionally I'll have one go out of range on the charger but the same pager if slightly pulled up on its own antenna is fine and won't have that happen.
I've got 2 G5's and a G4 snd 3 amplified chargers and regardless when they take a mood to they just go out of range with no rhyme or reason to it.
Good luck getting it sorted out.

I have replaced the amp charger supplied antenna with an RS 800 antenna and have never experienced an OAR. My monitoring P25P2 systems transmitting antenna is 5 miles from my QTH.
My bet is that there is something going wrong between the antenna connection on the charger and the contacts for the Unication causing just enough RF loss.
If worst comes to worst, you could attach the antenna cable where the Unication antenna connection is. With this going to be a fixed set-up and there being no reason to remove the Unication from the charger, it should not be a problem.
The only issue you might have is people tinkering with the volume levels. We had that challenge when we had scanners at the fire stations.
