3 questions:
1) OK, we know that in mid-94, Moto made changes to prevent channel expansion of 2-channel units. How does this affect 8-channel rigs?
2) Batwing added a comment to the Hoffis codeplug mod procedure about fixing the checksum. What happens if you don't fix it? I ask, because I applied all of the Hoffis changes to my GP300 RSS, then modified the model (P110 to GP300 16 channel) in the codeplug and loaded it in radio without correcting the checksum. The radio works fine. As a test, I subsequently read it with an unmodified copy of the RSS, and it didn't complain.
3) Can I change the squelch setting via RSS with the normal programming cable, or do I need the service cable?

GP300/P110 questions
Moderator: Queue Moderator
Question 1 I can answer. I have converted the 8 channel GP300's Post 1994 without any trouble. I believe the most recent one I did was a 1997. If my memory serves me I also converted a 8 channel P110, I don't have the radio in my posession, so I don't remember for certain what it was. The other 2 questions I can not answer though. Hope this helps.
That gives some hope. What method did you use to convert it? Hex editing the decrypted plug a la Hoffis? Or did you modify the mdf file?On 2002-03-21 16:25, streaker wrote:

Another issue I have to deal with is the '97 8-channel P110 is not supported by my version of the RSS. I'm wondering if I clone it from a supported 16-channel GP300 will it accept it, given that the firmware version in the radio is newer.
1) There should be no issues with 8-channel units, the change only affected the 2-channel units. The microprocessor will recognize all switch positions in an 8-channel unit.On 2002-03-21 13:26, TomSlick wrote:

2) It may vary depending on which RSS version you are using, some may do a checksum validation, some might not. I don't know which versions will/won't. From the sounds of it, you are using an older version RSS. The radio itself doesn't really care.
3) Yes, you can adjust the squelch with the normal programming cable.
4) You'll have to try cloning the older GP300 into the newer P110 to find out, I suspect it'll work, but can't say for sure. Good Luck,

Many thanks for the info. I'll give it a try and report the results.On 2002-03-22 11:17, wavetar wrote:

Crap. Tried a couple of different things on the 8-channel P110, and now I get the dreaded beep-boop on powerup. The basic problem is the versions of the RSS and Toolkit I have don't support this model. I tried to force a codeplug from an earlier P110 into it.
Anyone have suggestions? Is this a matter of the ROM version in the radio that's preventing an older codeplug from being loaded?
It was sort of "nothing ventured, nothing gained", as the radio was useless to me as it was (except to sell), since I had no way to program it.

Tried one more thing - I read a '97 vintage 2-channel P110 and tried to write that plug back into the 8-channel P110. No go.
Neither the RSS I have (V.7), nor Toolkit recognize the 8-channel P110 model. I thought at first if I just modified one of the existing models in the RSS MDF file to match this model number, things would work, but the RSS still gives "model not supported". I'm guessing it's because of the ROM version, which is 4. (The 2-channel is version 3, and is supported by the RSS).
I tried to force the codeplug into it with the RSS using the Hoffis F8 hack, and it seems to write, but the radio still gives the error tone on powerup, and still isn't readable. Clone won't work due to model mis-match.
Anyone have any suggestions as to how to get a good code plug into this radio? Is any attempt to force an older plug supported by my RSS doomed to failure because of the version 4 ROM? I hate to give up on this one.

Another thought: is there any sort of component swap I could do between the 2-channel rig, which I can program just fine, and the 8-channel "problem child"? Since the 8-channel doesn't have the 2-channel-only design, I was thinking maybe I could use parts from the 8-channel to make the 2-channel capable of expansion. (Or use parts from the 2-channel to make the 8-channel programmable - maybe a ROM downgrade?) Just pondering...
