What is the clarifier mod for the Ranger 696F? Any other good mods
to do? I assume the extra channels are the same as other MB8719 PLL
radios.

Good luck.

There is someone that know where I can find a schematics for the
boar EPT360010A? (Lafayette Typhoon, Galaxy Saturn)

Thanks to all

The mod you want it's quite easy! ;)
Locate the trimmer marked as VR13 this is the AM Power control, it
is a 5K trimmer, if you want you can use the commad of SWR Cal (it
would be a 5k variable resistor)
Anyway you can find all details at:
http://www.geocities.com/dre_cb/alan/ept360014b.htm
by the way, your rtx have only 2 final transistor (2 x 1969 or
similar) and 1 driver

I hope to listen you asap on the air

     Part value changeover mods are usually
     regurgitations of what specific techs like
     to do for their own reasons.  When analyzed
     you find that most are misguided and therefore
     inferior to simply removing the active device
     in the limiter circuit and setting the mic gain
     properly.

Hi all, I've a little problem: my radio is broken off and now in SSB
only pushing the tx button the output is 21W (the max output for the

Sorry if this question has been asked but my search came up empty. I
just picked up a used (like new, unmodified) Cobra 148 GTL ST (not
the NW). I have owned the 148 XLR, 148 GTL, and Uniden Grant.
1. Is there any real difference with the ST model? If so, what are
they?
2. Is the frequency mod, RF tune-up, & modulation boost process the
same?
Thanks!

Yhanks, but the unit must be powered on right?? When I reset the bios
on any of my clients computers because they @$&! forgot their bios
password they must be powered on so I guess the same goes here. I was
afraid of shorting out the whole damn unit :)

Thanks

     That part should be essentially the same.

     The 3-pin regulators are cheaper.  Cheaper
     is the reason for 99.9% of all changes to an
     exising design.

> Anyway,that is the
> section i am looking for info on.

     I don't see too many of the newer 148s.
     I still have a source for Grant LTs

     The 3-pin regulator is a 9 volt regulator.
     The leftmost pin is the supply pin, the
     center is ground, and the rightmost is
     the output.  Then the output is run through
     a rectifier diode to lower the voltage by
     roughly 600 mV.  They must have gotten
     a special deal on a large quantity of 9 volt
     regulators because 8 volt regulators are
     much more common and should be cheaper.

     In any case the 9 volt regulator is a constant
     (TX and RX) voltage source.  If the 9 volts is
     there all the time, it's okay.  The only problem
     is that I don't think they included an adequate
     amount of RF decoupling.  The reason I mention
     that is because I've found that whenever I've done
     an aggressive tuneup to one of those units I end
     up with sideband distortion.  The solution is to
     add .01 uF decoupling caps to both the input
     and output of the regulator and the PLL chip supply
     pin.

     As for the TX/RX switching, I don't have any specific
     magic words for you.  In my experience, most TX/RX
     switching problems can be found fairly fast by simply
     starting at the mic jack and working your way in until
     you run into the unexpected.

> Also the little module that runs
> the lights on the front face.

     At best all I have is a very bad 11 X 17 drawing that
     I wouldn't call a schematic.  If you want to dig for it,
     scan it in and send it to you, let me know.  And even
     at that, don't get your hopes up because I can't say
     for sure that I have it.  My suggestion is to keep at
     it using logical reasoning and you own notes as you
     progress.  Your own notes will be of a helluva lot more
     help than what I have if I have it.

Hello group. It is nice to see a group on here that deals with cb's.
I go by Wizard on the radio. I run a cb shop in odessa,tx,Driver's
Haul Of Fame By Dad Carter. I am curious. Is there anyone on here
that shares schematics or might have one for a 148 gtl nw st? I have
several companies that I deal with and none of them have one
available for sale. And still others say that it is the same as the

I am having problems trouble shooting the tx/rx switching. The fact

They should have left the mb3756 there instead. Anyway,that is the

     If it doesn't suit you as is, buy an AB class 8-pill
     like a Texas Star 1600 and use your current amp
     as a driver.

     CB DX happens most in the bands that are just
     above or below the normal 40.  Try the band just
     below the normal 40 for AM, and the one just above
     the normal 40 for sideband.

To a degree it's the same as an old 148.
     It depends on what section you're working
     on.  I've got a binder of new Cobra service
     info.  The schematics are really bad, but if
     your problem is with an accessory circuit
     that the old service literature (Sams) doesn't
     cover, let me know and I'll see if I have anything
     that might help.

Hmmmm.....Not exactly sure I've located where to jumper to reset the
unit...I don't see C506 printed on the board or chip...I do see a
VERY small vertical chip..is that it? If so, I assume the unit must
be powered on before shorting both sides of this chip...it's brownish
with two ends that look like solder or tinned ends....
