P110 Channel selector

Post by N0SIH »

Hello Guru's. Got a quick question for you guys that have been there-done that. I have a 6 channel UHF P110 with a broken shaft on the channel selector. I also have a broken 8 channel VHF P110. Will the channel switch from the vhf radio work in the uhf radio? Out of the housing they both have 16 detents stop to stop. Thoughts? Thanks and 73 de Jeff/N0sih

Would you like two brand new 16ch pots - no charge?
The same 16ch pot is used in both 8ch models and 16ch models (GP300)

The P110 is simply an early GP300. The boards fit straight into a GP300 housing if you want to make it slightly smaller and more modern looking! GP300 batteries are cheaper than P110 batteries too...

Hello :
No thoughts on this one.
Yes all GP300 and P110 2ch/4ch/6ch/8ch/8ch plus/16ch use the exact ch switch.
The only thing limiting additional ch selection as to positions is the knob itself.
Also if it was manufactured before 1994 then it would convert to 16ch and i do have 16ch eschuteon labels for both the P110 and GP300.
The two use diferent labels but many were not aware that the P110 was even produced in the 16ch version but i can assure you that it truly was.

Hey thanks for the generous offer Mdealer. I will try this used one I have and if I have a problem with it I will PM you.
I have never even seen a GP300 so I will have to take your guys word on that. This radio was only used for 2 channels when I got it but it will only accept 6 total thru RSS add mode. So it must be the oddball. I did not look up the model # on batlabs. I took it out of the case and used my X-acto hacksaw and made a slot in the shaft to use a small screwdriver to change channels. Kind of a pain but works. Also below the monitor button on the side is another button but no blister on the side of the case to access it. What is it's function? Thanks for the info satelite. 73 de Jeff/N0sih

Hello :
If you can only get 6ch put into the radio then id really have to believe it is a 6ch P110 model in a 2ch case.
The p110 only gave you access to one of the side buttons and it was programable in the rss for monitor or Vol setting as i recall.
The Gp300 gave you access to both buttons which allowed programming for both options ect.
Since the P110 guts was primarily a GP300 without the fancy frills of a GP300 they both as far as the electronics are concerned were pretty much the same radio.
A P110 6ch normally can be converted to a GP300 16ch with scan /DTMF phone if you add the front to it without much trouble assuming you know how and familiar with the process.
Basicly you over ride the P110 code plug and force or edit in the GP300 16ch code plug.
Since the code plug chip is the same the radio would now believe it was a GP300 and you gained the extra GP300 features because it is a GP300 per code plug info.
As already stated above and absolutely corect = You can remove a P110 radio from its case and put it in a GP300 housing.
I prefer to do this as as stated better battery features and you now have a battery deluxe spring loaded belt clip carry option that the P110 doesnt have.

Okay on that satelite. Let me back up and say only 2 channels were programmed into the radio but it is in fact a 6 channel radio with 1 thru 6 around the selector. Model # is P44qlc20b2aa. Are 16 channels available.? If you force the new codeplug in can you still access it with P110-RSS ?Thanks and 73 de Jeff/N0sih

Hello :
According to the model number you provided and assuming no one swapped the back chassis with the M/N ect.
And im qeussing that since the 6ch front matches the chassis M/N that it is as follows.
Your P110 is a 438 to 470 mhz 6ch UHF 4watt 25khz wide band version.
Yes you can turn it into a 16ch and use the P110 rss if you hex edited or forced in the P110 16ch code plug.
But id actualy recomend turning it into the GP300 16ch version even if you decide to leave it in the P110 housing as it is now.
But if you go the GP300 route youd need to use the GP300 rss instead of the P110 rss.
The GP300 and P110 use the exact same programmer setup with the exception of the rss for each is diferent.
Your 6ch P110 may in fact only have two ch programmed into it but you can add the other 4 ch modes to get 6ch in it per the P110 rss.
Or convert it to 16ch then add the remaining ch modes up to 16ch operation.
As i recall the 6 ch did allow scan operation as well.
You simply dedicated say for example ch 6 as scan.
Any ch could be the scan ch if you wanted say ch 2 to be the scan then you per the P110 rss made it the scan ch rather than conventional.
This is also true for the GP300 but if you went GP300 you could make two seperate scan ch banks for example ch 8 could be scan 1 with say ch 16 being the second scan bank.
This was popular here in my area when an individual only wanted to scan 7 ch in one area but wanted another scan bank without the freqs in the other scan bank for another area of operation so he didnt have the unwanted extra freqs in scan also.
But be aware that when you make ch 16 a scan ch that you loose that ch for tx as its now only a rx scan ch and if you make a second scan bank that ch also looses tx rights and becomes a rx scan only which would leave you with 14 ch to use as tx/rx since two channels are programmed per the GP300 rss as scan only.
I see more qestions coming . 8) Im still around here now and then on the bd.

Satelite, sounds like you know your way around a p110 or two. I,ll try your suggestion on the scan tip. Nice to know that.
So basically a codeplug is the instructions for the radio to behave with then. I have never fooled around in that aspect of programmable radios except for some old RCA TACTEC rigs. Sounds interesting though. I did see a gp300 in FSWT so I know what to look for now. Yea the belt clip for the P110 is crap. One other question though,do I need a different charger for the 300?Thanks and 73 de Jeff/N0SIH

I'm 99% sure that the chargers are the same.
If you want some GP300 housings and second-hand batteries free of charge let me know.
I must throw about 50 second hand GP300 batteries away per month simply because the customer would like brand new ones, regardless of charge capacity and battery condition!

Just so you guys get the story straight, the GP300 RSS was made in at
least two versions. The first one worked on the GP300 and the P110,
and the next one worked ONLY on the GP300 and the GP350. There is a
specific READ ME note in the second version that gives this information.
My information is based on working with US versions of these radios.

The chargers for the 300 and 110 are the same.

Hello :
And also to add there was a specific P110 only rss .
True there is a p110/gp300 rss and a gp300/gp350 rss.
Motorola did try combing these together awhile back and it would appear she didnt settle on any specific combination of rss on any of the three mentioned.
Also it seems the P110 6ch versions many many times would not respond to the GP300/P110 combo rss and you got the radio not supported error code 21.
But the 6ch P110 in this case would respond to the P110 only rss.
Not sure if it was a backwards compatibility with the GP300/P110 rss combo.
And you are corect = The code plug is the programming info and the specific files as to what makes the radio what it is.
Since you admitted that this a new area to you please read the below.
READ AND SAVE THE CODE PLUG READING TO A FILE OR DISKETTE BEFORE YOU ATTEMPT ANY PROGRAMMING CHANGES !!!
I capped that because if you get messed up or corupt the code plug accidently you will be able to return the radio back to operating condition.
Read radio / select save code plug/ then enter the info youd like to remember the radio as / and save it to the hard drive C or B for a floppy or diskette.
This saved info will be more than the ace up the sleeve should you mess the radio up.
All you need to do is get the saved reading and program it back into the radio and it will return everything you did back to what it was before you changed things and be a working radio again.
Additional qestions or help available if you need it.

Good info all. Mdealeruk I will PM you if that is OK. Yeah Satelite I was having a brain fart there. I knew that the codeplug held all of the specific radio info but for some reason I was thinking you had to change some other area of the radio to fool it into thinking it had a new identity-not personality. I hear you on the saving the codeplugs. I always save the original file with persons name and serial of radio.to a seperate archive for the very reason you mention. RSS I have for the 110 is r08.00.00. 73 de Jeff/N0SIH

Re: P110 Channel selector

Again, going from memory the GP300 version software was for GP300 & P110 upto version R07.xx.xx (R07.02.00 i think)
and from then on; upto the the final release of version R08.02.00 it was for GP300 & GP350.

I also remember someone saying do not read a radio using any version below R07.02.00 if it has been programmed with version R08.02.00 because version R08.02.00 adds some new options and settings; like battery threshhold etc and the early version will not recognise the figures/values. I've just programmed a radio using version R08.02.00 then read it into R01.00.00 (the very first release of RSS) just to see what happened and the radio read fine, so it can't be that important but i know i read on a post somewhere online that you really shouldn't...

I know that a lot of the UK dealers only use version R07.xx.xx and don't use version R08.02.00 due to certain changes made.
