Batboard

hi all im new here but i see there is a lot of people who know their stuff....

i have a motorola m1225 vhf that does not receive at all

nothing happens on the screen when trying to communicate with other radios it tx very well loud and clear but nothing comes in

does anybody know where i could start to check i have all the equipment to read/write to the radio

also is there anyway to bring that radio back to default settings it was loaded with phone frequencies and i think there was an external speaker on it as well

i would like to fix my receive problem and/or put it back to its factory default settings


thank you in advance for your help and time

Step One: Press and Hold the Mon button and you should hear noise in the speaker.

Step two check for a Handset setting in the RSS, that would mute the speaker. It should be set to OFF.

Yeah, if memory serves me, when people connected an external speaker to the M1225 the "internal" speaker was still connected also.
So, some people opened the case and either cut the wires or unplugged the internal speaker.
The "Step One" test above should tell you. If there is ANY noise coming out of the radio, then you at least have a speaker.
If not, then either open the radio and see if the speaker is disconnected or go to the Batlabs site and look under radio specific info to
get the pinout for an external speaker.
If you get noise in the speaker, but no RX of a proper on freq signal, then the radio might have other problems.

yes the speaker is working fine, when on monitor i opened it its connected inside also i will check again with the rss for the mute speaker option but i don't see the little lightning icon(RX) when i TX with my 2nd radio....

frequency are the same and no RX

thanks for your quick replies i really appreciate


still no luck will try every solution i get, is there an option in rss that would block the radio from receiving?

"Frequencies are the same and no RX" can mean that you have either PL or DPL set for receive in one or both radios, so dig into the software and be certain that both radios are set for CSQ in both receive and transmit. If that doesn't work then go through the software thoroughly for one channel and check ALL of settings in the program.

OK he has a speaker connected and working.

Seems the RX is not receiving as there is no BUSY indicator.

Next is to check if the second oscillator is working, the one that is used for the second mixer in the RX.
Then check the actual RX injection frequency from the RX VCO.
