Moflag / BitBang failed on Spectra VHF A5 radio
Posted: Tue May 07, 2019 11:51 pm
Dear All,
I'd like to ask for some help from you. I wanted to revive one of my older analog-only Motorola Spectra radios. Originally it was a VHF model with an A5 control head (D43KXA4JA5BK).
Its command board was damaged due to a power surge and the traces were blown on it. I have replaced the command board and the MLM board as well. Now there is a v6.15 MLM in the radio. I didn't like the A5 head so I have switched to A4. Theoritically the MLM board supports zones (v6+) but I am having issues with enabling this option in the RSS.
I was using the following source of information to do the modifications needed:
http://www.batlabs.com/moflag.html
and
http://www.repeater-builder.com/motorol ... nging.html
I have reutilized the command board, aligned the proper bits to match the model number and the control head type, so it seems that almost everything is working fine. The radio now acts as an A4 VHF model. I can read it with the RSS, I can write it with the RSS, I can transmit and receive with it. The RSS version is R06.xx.xx.
I have also used the bitbanger in that special RSS to modify the MLM board values and the command board values to match the new features of the radio.
My problem is: the modified MLM values are stored properly in the MLM, the changes I have made are saved and they can be read out after powering off and on the radio...
...BUT...
...the command board always loses the modified data and reverts back whenever I turn on and off the radio. Don't forget that the radio resets itself when you exit from that special RSS' service section.
What am I doing wrong?
Please help me
Thank you in advance.
