Motorola P1225 speaker mic issue

[zackman1801]

I recently acquired a Radius p1225, and am having some trouble with my speaker microphone working with it. When i plug the speaker mic into the radio it makes a series of beeping noises. After the mic is plugged in each time you key the mic it makes the same series of beeping noises, im unsure if its transmitting anything but im wondering why it keeps making the the beeps? There is a possibility that the ports are damaged and thats why these radios were decom'ed, or is it something else that might be effecting the radio? I am using a standard 3.5mm audio jack, and on the Motorola website it lists the Radius p1225 along with the CP200 that im currently using the speaker mic on now, so i know for a fact the mic works.

On a side note does anyone know if the radius P1225 is a paging radio? As i have stated in other threads, i am a firefighter and would like to know if the radio has paging capabilities when tones are picked up.

thanks for any info
Zack

Plug in the speaker mic, THEN turn on the radio.

Im achieving the same results. The radio makes one loud beep followed by 3 lower pitched beeps.
The radio now seems to be doing this without the mic attached. It could be a problem with the radio i guess as stated before, and thats why it was decomed.

Sounds like the low battery alert, do you have another known good battery to try?

 

[zackman1801]

Yes i realized thats what i must have been shortly after posting that last time. I have a few different batteries to try now, although the charger takes a LONG time to charge them. and i believe that the batteries are all pretty worn out. I am more than likely going to have to buy a new battery for the radio if i want to have any chance of it lasting for any amount of time.

Aside from that my other question still stands Does anyone know if the p1225 is capable of paging, or has any alert features that would set it off.

Sorry for the double post. I just made this video which explains pretty well what is going on with the radio. The battery seems to have good power as its been off the charger for 3-4 hours now and it hasnt died or made any indications of doing so. But the problem still persists. I am thinking that these radios have been made receive only for some reason. Seems strange for a FD radio, but who knows.

Thats the low battery alert, your battery is shot. My old battery got to the point where it would do this so i ordered a new one and it worked fine.

Ebay sells them for around $20.

It takes a LOT more power to Xmit than recieve.

EDIT:

As for the tone alerts, I do not think it has this capability.

 

[zackman1801]

Yeah, i ordered a new battery yesterday, should be in the mail soon. Its strange because if i leave the radio on the channel labeled "Scan" i can atleast make my other radio pick up a slight signal. My radio will click like it is receiving something, but i can not talk through the 1225. All of the other channels are a no go though, although this might be a programming issue as im unsure if our radio frequencies have changed at all since this radio was in service.

Yeah, battery is clammed. Freshly charged battery should be over 8 volts. If you check yours, it will probably be less than 7.5 volts indicating a bad cell. Thats the only reason it would die straight off the charger.

On the up side, the P1225 will decode two tone QCII. Go to the signalling menu and add a system for QCII. Put in tones and such. Then go to the channel of your choice, and under receive use menu to select QCII as signalling system.

Hollar if you need more help....

i thought the P1225 had to have an option board to decode 2 tone?

as far as the battery goes, a bad battery can make a portable do strange things. low voltage drives the ICs nuts. i have had radios that would not swap channels when you turned the selector switch due to low battery voltage, they just randomly chose a channel and that is what they use.

also, if this radio has been OOS for a long time it should be checked by a technician. even though it is synthesized, it uses a crystal reference oscillator. over time the crystal continues to grow and will make the radio go off frequency. Moto actually recommends any radio stored over 1 year be realigned before going back into service. usually they are ok for a couple years, but over 3 years of storage and i see at least 80% that require alignment or replacement of the reference osc. radios that are in use regularly do not drift as quickly, as the osc does not grow as quick. but they still should be checked out periodically. back in the days of crystal radios everyone knew they needed a check 1x a year, folks think synthesized don't require that but it is best practice!

To be sure I fired up the klunker, loaded the first archive I had and checked signalling. Sure 'nuff, it has QCII as a signalling option...

 

[davidgcet]

ok, maybe it was to encode QCII or one of the other codes. like i said i have had limited experience with the P1225, in my area few folks bought them. we had a bunch at one of our other shops, but the location i work had maybe 1-2 out there.
