900 mhz jedi software mod
Hi All. A friend of mine got an mtx9000 that would not tx on repeat or direct. Being fairly motivated, he dug up the correct spot in lab 2 to fix the problem.
In the labware, in labtools 1, there will be an entry for fractional-n synthesizer , f5 I believe. What you are looking at is the hex values for some comparator voltages in the vco control software. the upper left item,TX cp bias, is a setting for the crossover point between the repeat and direct VCO's. If you shift the value down in steps of 500, i.e. if the radio has a value of 6B80 (like mine) try moving it down to say 6800, then down to 6400 then down to 6000. you will need to write the codeplug between each value change. if you reach a point at which the radio will now tx on your lowest freq. then you are set. go too low and the reciever will unlock. On the top right side of the page is the setting for the direct mode. Mine locked fine on repeat (25 meg offset here, thankfully) but not on direct. I shifted the top right value down to 6000 even and all is well now.

That's handy... I've got a few MTS2Ks that won't lock up where I want them. I hadn't had a chance to attack that particular problem, but now it'll be a bit easier...
Now, if only there were a simple front end filter adjustment (I know, ain't happening.) I think I've come accross one who's front end rolls off too high to use...
Thanks,

I've got a couple of MTX9000's I'd love to adjust the TX VCO crossover point on but, my Labtools (version 3 I believe) won't let me do it. I see the option but, it says something like "not needed on this model" or something like that.
Would Labtools 1 let me do something that 3 is not?
I'm stuck and would REALLY like to get my TalkAround working.
Thanks,
John

You are looking in the wrong place.
First read your radio [F3 - F2]
Then go to: "F4 - Change View"
Then pick: "F9 - Labtool Configuration Menu"
Next pick: "F2 - Labtool Configuration 1"
That is where you will find the F5 selection mentioned in the original post.
BE CAREFUL - you can FUBAR your radio real easy with Labtool.
