Can the Motorola CM140 MDM50RNC9AA2_N be programmed out of range frequencies
#89141 (In Topic #76618)
I've been browsing the web in search of finding out if the Motorola CM140 MDM50RNC9AA2_N can be programmed to accept out of range frequencies. Basically to cover the 70cm ham band. Obviously with only eight channels it would only need to cover a handful of repeaters but as the output for these repeaters is in the 430mhz range, i'd need to be able to program the radio to receive.
I've found very little which probably suggests that it can't be.. So, can anyone give me any advice as to whether or not it can be. I know other Motorolas can and have been but there seems very little info regarding the CM140.
I've five of these radios in excellent condition, sat around doing very little and wouldn't mind putting them to good use.
Kind regards, James.
I've been reading about hex editing. Do you have a guide as to how to do this.
I've read about it being done for other radios but I can't find any info with regards to the CM140..
Thanks for the reply and kind regards, James.
No problem and thanks for the reply.
I've been searching again today and just gone over pretty much the same things I've found previously.
Thank you anyway.
Right, all done. I managed to find out after a lot more searching just how to do this. Hex editing was the key and rather simple to do after I found the right information to follow.
So I now have five (you can never have enough radios) to mess around with.
The next project is to make a repeater from these radios.
Looking into that now.
All the best, James.
Do you have the procedure?
After editing the file with "Hex Workshop", I can not read it with the CPS program anymore.
Sorry for the late reply.
I believe that I uploaded the original codeplug back to the radio. If you look up on the web using the radios serial number you can find the original for the radio. I'm almost certain that I found that from Hamfiles itself..
I'm far from an expert and more or less stumbled into how to do it as there was very little help on the web.
That was the only way after altering the hexfile that I could get the radio to talk to the program. I did this a few times with success.
Obviously all your reprogrammed information that you hex edited will be overwritten so you'll have to do the hex edit again but that was the only way that I could edit the TX and RX values.
Hope this helps.
