Hi group, I have a problem trying to expand the bands on one 920 rig which had its mainboard replaced but I can't do it. First of all, the mainboard doesn't have the green cable that should be cut between q2510 and r2544 I've marked the space with a blue line inside the red circle. There's only one green cable further down marked with a red arrow, I've tried with this one without success cutting it and entering the code as indicated by the mods that are floating around the web, but the radio only emits one beep instead of two which indicates that the passcode was not confirmed. Is there another method or passcode number of unlocking it?

The radio set to OUTSIDE too in F33 Service menu.

?

Thanks in advance,

?

HI8-NPM

Hi Jim and thanks for your fast answer, i have the original main board damaged by another problem but it receives well and has the mars mod, I know of an executable file under the old DOS operating system that seems to update the band table in the eprom but I have my doubts about using it. Do you know if the 920 stores this data in one of the 2 external eproms or in the cpu itself (MB90P263), perhaps I could copy its data and rewrite it in this one. Thanks again Jim.
