Hi all, I realise my question does not relate to FM900's but I have recently been given a Philips PRP1650 and cannot find any info on this radio. Is there...
Hi Rick, brief answers (as I too know very little about these as well) Trunking - MPT1327 protocol From Phillips label : T band 403-420 Mhz (fm900 T band) ...

I finally got my butt into gear and remembered an old sales brochure I had for the MRS91 - an FM91 (or dual 91) mobile repeater. I have heard a bit about...
Hello all, I aquired an FM91 U band set recently with the plan to get it on to 70cm. This is the first time for me to have an FM91 and have the pleasure of...
Terry, Yep you can. They are set per chanel If I remember correctly the 91 will allow you to change the setting from the remote head as well… VK4TAA - Peter...
Thanks Peter, I just can't see in FPP where the tone is programmed in, I suspect it is the "SA order Characters" from the frequency programming table? I can't...
I think I figured it out..... I was getting tone 162.2Hz programmed on all enabled channels. I was programming 'Y' {for yes} in the ctcss location, SA order...
yes you can change the ctcss tone from the remote head but you have to have a tone on that channel and it will allways default back to the set tone for that...
Yep got it sorted (in my head anyway). I will do another eprom burn when I get to work. (burn number 5 I think). Thanks Peter and Daniel. Terry ... From:...
Looking for a kind soul on the Gold Coast or Northern Rivers who would game to help me get an A band FM92 aligned so that it'll get down to 2m? Cheers, Steve...
G'day all, just picked up a couple of remote A banders that have had the 12.5 mod done to them. Tried putting a 25kc chip in but the thing would not lock up ....
... If you're using a ROM programmed for 25Khz channel spacing it will not work, as the synthesiser is programmed differently for 12.5Khz. There are two...
Trying to reprogram an FM92 for uk 2m band. Have FPP running in dos ok but have no Eprom burner. Borrowed a Stag M101A programmer but this only interfaces to...
Hi Group Is it OK to swap the synth board from one radio to another? I have 2 FM92's one is E band local head ex commercial (no mods yet) the other is A band...
Hi Rob, You only need to make a bin file with fpp and then take that bin file from fpp and run it with your burner software to write to the eprom. You use...
Rob, Just to elaborate, FPP will create a binary file in a subdirectory of the C:/FPP/FM900/JOBS with the name of your project (like MY2MROM.BIN). It does...
Hi Steve, You can swap FM92 control/synth boards but there are some subtle differences in a few components in the synthesiser prescaler and VCO control...
Thanks Mark Ok then, if I just move the CTCSS module and the NSC810 chip is that enough? The small chip & components next to the NSC810 are already there ...
Thanks Mark and Mat for the info, I'll bash on along those lines but will probably be back with more questions :) Have no h/book for the programmer and I am...
Hi Rob, Having a compatible parallel port programmer would certainly be nice, but I don't know if the schematic has ever been published. I'm fairly sure the...
Hi Steve, There is a link or two on the PCB that needs to be changed when fitting the NSC810 "I/O Expander Kit", and another that may need changing for the...
Hi Mark, I have used a number of programmers over the years , none of which was compatible with the FPP software but all had no problems with programming the...
... due to one or more or most likely all of the following reasons old age poor sight not looking close enough, poor light and a massive infection getting me...
Hi Alan, Looking at the circuit, it would appear that offsetting the connector would have applied 13.8 Volts to the internal +10V Tx supply, which powers the...
HI ALL JUST WONDERING WITH THE PHILLIPS FM900 I JUST BROUGHT I THOUGHT IT WOULD BE A NORMAL 40 CH CB BUT I WAS WRONG CH ARE ALL OVER THE PLACE AND THEY ARE...
Hi Graham first you have to get the fpp program and write a bin file for what you want in the radio the you have to have a eprom burner and put the bin file...
Also with the programming you need to know if the radio is fitted with options EG: sellcall board Type 1 or 2 , ctcss encode or endode decode board and the...
Daniel, I think Graham is looking for someone else to reprogram it. I'm sure there are standard EPROM binaries around on the WEB - all he needs is someone...
