Just got my hands on a SP50 VHF 2 channel... I have seen the 10 channel versions. Anyway to make the 2 channel into 10 channels??

Expanding the number of channels in the SP50

Locate the actual model number of your radio in the .mdf file. Copy down the two bytes prior to your model's name.
Locate the model number of the radio that you want yours to become (i.e. g2__ instead of a2__ etc.). Copy down the three bytes before the name of this model.
SWAP these two sets of numbers. By doing this, you have not only made your model have all of the features of the other radio, but you have also preserved the all important MDF checksum!
Example for a P94YQT00A2 being converted to a P94YQT00G2:

Start with:


Note the highlighted bytes preceed the model you are trying to change.

Finish with:


This modified software will now read your 2 ch radio as a 10 ch or whatever other model swaps you have done. You will of course want to save this hacked software in a separate directory and use it only to read your 2/10 channel radio because if you now read a factory 10 channel radio the last 8 channels will magically disappear because it now thinks it is the 2 channel one!

All that is left to do is to stick on a 10 channel escutcheon and knob and you are ready to talk!

Also note the 0x04 at offset 0x57C, this is the bandsplit identifier for this model number and corresponds with the entry in the bandsplit table at the top of the .mdf file.

Keep in mind, that if this mod. radio is read by ANY other RSS software other then the one YOU have modified, ...POOF!! your radio will read to "them" as a 2 channel only.

Keep a back-up of your software in a safe place. At the very least, print off the page that details how to do the mod.
