Quantar Backplane
Does anyone know if it is possible to get a replacement backplane for a Quantar. I have one that was damaged (small fire in the repeater) and would like to rebuild it if possible. No other damage besides the backplane. Thanks in advance!!!
Re: Quantar Backplane
Do Not know if the backplane is avaiable.
Small Fire, details please
Small Fire, details please
Cause Motorola said so that's why
Re: Quantar Backplane
I agree, more details please.
As for the backplane, I know we've had them replaced at the depot a couple of times due to random weirdness, but I do not know if it's an orderable part.
I do see empty chassis units with backplanes appear on eBay from time to time.

Re: Quantar Backplane
ditto details, and ditto looking for a good used Quantar rather than trying to buy a replacement backplane.
Re: Quantar Backplane
Found this info. Not sure what is meant by the metal bracket.
Quantar back plane part# 0184856T01
Quantro backplane is 0184856T03
The part number of the metal bracket is 0784735T03
The screws if needed are 0310943J15, Qty 12

$1,146.60 list on the backplane (Quantar). Might as well wait for an empty cage with backplane to show up on eBay for that price.
Re: Quantar Backplane
One rainy night during the winter I got a call from the station reporting the the radios were down. I tried to hit the repeater and it did not respond. So I responded to the tower site and when I opened the door the room was full of smoke and it was coming from the repeater cabinet. I opened the cabinet which contained two quantars, when I looked inside I had a nice little flame coming out of the top of the Quantar at the spot where the wireline card connects to the backplane. I killed the power and got the fire out and once I cleared the smoke I found that in the 15'x30' building containing our repeaters and a ton of cell tower equipment an ice dam had managed to cause a leak exactly above our repeaters which dripped onto the cabinet and through the unpunched holes on the top into the quantar causing a short which caused the fire. So I spent about $14,000 for a new quantar because the backplane was hard to get ahold of and now I have the other one sitting on the bench, so as a side project I was going to try to get it going again.

also I apoligize for the late responce with the details, it has been a busy Holiday weekend.

That sucks. Any possibility of an insurance recovery?MPDREO wrote:One rainy night during the winter I got a call from the station reporting the the radios were down.

Re: Quantar Backplane
Saw fire once from a Quantar but no water. was that damn crappy Onan supply puking. At least it was contained to the P/S unit.
Re: Quantar Backplane
Is it possible to replace a Quantar backplane with a Quantro backplane?
I'm not an expert in this, but they look very similar - what's the difference in functionality between the two?

Re: Quantar Backplane
There are others out there with more expertise but I believe that the answer is "no" if you want to use it as a Quantar rather than as a Quantro.
The Quantro is set up for an external (MSF5000 style)12 volt power supply. I don't believe that the Quantro backplane has the connections for the Quantar supply. I am not even sure that it has the opening for the AC power cord.
The Quantro also uses a (MSF5000 style) external PA. I don't believe that Quantro backplane can accept the Quantar PA.
The receiver, SCM, and exciter modules are the same between the two stations.

Re: Quantar Backplane
We tried insurance but because it was not specified on the municipal policy they would not cover it. There is now a special policy in place for the repeaters so if it should happen again we would be able to put in a claim.
