Hi Beekeper. I was just reading some posts here and saw this one. I have a CDM1250 42-50 Mhz split that I would like to put on 6 Meter ham. How did you program it up into the 50-54 range. Must be a "variant" version of CPS ? Interested in more info if you can share it on how this works. Di...

The EF Johnson 900 Mhz ascend series will do it
after using modofied programming software.

phrawg

And I thank you sir. I will look at that config and see if I cant then fabricate some
form of a "crossover" cable that will allow commection into earlier Radius, Maxtrac,
etc that use the 8 pin modular. Seems that should be do-able.

KInda figures. So much expensive disposable stuff now days. well let me ask another way then. Anyone know the "pin-in" for the 5000 console and that would sure give a clue. The board in the mic has 0nly a few surface mount caps and 3 small 3 pin devices on it. Thanks for the input so far. ...

Been a LOOOOONG time since I have been here but have a question. I need a schematic or at very least the pinout for a desk mic. It is the oval base with the slim flex gooseneck. Numbers on the bottom are model B1914A and the barcode strip says MBMN 1000e Anyone able to help ? I have several of these...

HEY OTAKU Pm me. I can fix you up I think. NEW and cheaper that those prices.or drop me a note at phrawgy@earthlink.net

There is a package which might stand a chance of working. It is called VMware (virtual machine ware) It truly allows you to use a xp based computer in (as I have my laptop set up) DOS, UNIX, and the root Windows XP. It actually shuts all other operations down and goes and runs the system you want. I...

Yes. Find an old computer. The 4 pin connector that plugs into old large
disk drives is the same. of course you need to move the wires around if you
are picky about colors, or just splice longer wires of the right color in and go.
the pins are standard Molex pieces. Hope this helps. Phrawg

I fifth, sixth, seventh (whatever) the vote. Looks good guys ! Like any new thing I will have to relearn some almost automatic mouse moves, but time will deal with that. Great job on getting it running that quickly. I didn't even have time to go into the Batboard withdrawal syndrome :lol: :D Thanks ...

phrawg

YEP, IT WONT WORK ! Either the program needs to be writen
for windows or dos. No crossovers when it comes to /\/\ software.

If a tag is what we were seeing instead of some links to
other spamish type stuff maybe we could help.
Check your link. Phrawg

phrawg

That is correct. BY the book ! loosen the retaining nuts on the bottom with the correct spanner driver and gently pull on the antenna to extract the chassis. All the while assuring that none of the side switch press pads are being depressed. Actually what I do is after loosening both screws I use th...

Just don't place them where they dont have enough air around them
for proper cooling.

So just what IS Nauganet ? Can anyone enlighten ? Maybe it is a special radio net set up for those creatures that used to be in tv commercials a looooooong time ago called "naugas". Maybe some will remember. They all "gave up their beautiful hides" so we could have "Naugahid...

I didn't know you could find them that way over in "stinkadena".
Doesnt the natural surrounding atmosphere mask what you are trying
to troubleshoot ? Phrawg in Houston, West suburb of Pasadena !

phrawg

Not so far as is known yet. Seems that the band split info is
in an area of the firmware that cant be gotten into. There are
folks working on this out there. Someone will find it one day. Phrawg

phrawg

First the radio will start to act "funky". Can be small quirks pop up all the way to total failure. Also look closely for darker green "stains" under the solder mask. It all should be an even green color. Probably the best all around way to remove them is to crush them from aroun...

phrawg

The keypad programming ability is for a "dealer master" radio. to achieve this a hardware change must be done in the radio. It is all in the discussions. If yours already does this then the dealer mod has been done. The idea was that a dealer could program one unit then clone it into the u...

phrawg

Yeah, just spread the case down the sides and pop it out.
The accessory plug slides up and the speaker in under a clip.
JUst use care. Phrawg

phrawg

NO, you cannot remove the cable during programming whether it is factory cable or aftermarket. It is just that the aftermarket cables tend to not attach as securely and are more prone to have intermitent connections much more often. The price you pay for an original can be considered as insurance th...

phrawg

A common problem when aftermarket cables are used. You can now be the proud possesor of a very pretty radio shaped "brick" which makes a great paperweight or doorstop, OR, send it through the proper Motorola channels where you are located to the factory for a firmware reconstruction. One w...

meggabad, Having a stupid ham ticket is not going to help you get Software, It all depends on where you live and how many radio shops you live near! Good luck! EXCUSE ME !!!!

phrawg

Check your TA settings and programming. It would not have transmitted on a split but there are separate settings for the pl or dpl for the TA transmit. Bet 'ya you were just not transmitting the correct or any at all pl or dpl and just not being heard. I always set my modes up so that " no TA &...

phrawg

PETNRDX please see pm's Thanks, Phrawg

phrawg

yeah. The cheap and dirty lock line is just that. A good way to instability. The vco really needs to be moded. There are several articles done on it. Not for faint of heart or ham sized fists, but it can be done. Also different vco's have different top out ranges. try several if you have access and ...

phrawg

You mean CDM ? So far no out of band for them as far as I know.

But then what do i know

Phrawg

BTW see model specific info section for them elsewhere on the board.
may have some updates.

phrawg

also ckeck that on the ham programmed channels
you are not set for narrow band. Phrawg

phrawg

There is a series of universal knobs made that use a collet type of attachment that are showing up in electronics parts stores. you pop a small colored cap out of it and there is a screw slot use to tighten it and it grips the shaft like a dremmel tool chuck. you can get them on all sorts of color f...

phrawg

Actually the coax is the thing you should look at first. That
one thing has stopped more repeater systems from working
than almost any other single factor. Phrawg

phrawg

Yeah, I think mine does it too. Normal. I will have to
look at it when I get home. I usually just listen to it
and dont watch the display.

phrawg

one of 2 things. If you have an amp behind that unit the 12 amp is
probably not supplying enough current and causing problems
or, the rf is getting into the 12 amp unit and causing it to mis
regulate and cause problems and the 40 amp is more immune
to the rf. Phrawg

phrawg

using saber RSS. Just go in and tell it what the model and other specs are and build it. then load it into the radio. Then go to the service menu and do a complete alignment on it. (this requires a service monitor and full alignment type programming cable). In other words the factory programming cab...

phrawg

In otherwords DONT TRANSMIT with it in the SVA without the SVA
antenna port feeding a real antenna or you are very likely to end
up with a saber that now has a fried pa module. Phrawg

phrawg

Well...... Help we are trying to do. but ..... :-? Yes, the antenna cut for 800 mhz could very well have blown the pa on the mobile radio. Now you have little or no power out. The one inch from metal truck cab is also a no-no. A vhf antenna needs a clear 18 inches around it or it is just like the 80...

phrawg

I would be interested also.

phrawg

Suggested to NOT use diodes or anything internal to the radio that is hardware. If you do then merely attaching an outside accessory will put the radio into continuous transmit. Do the hex edit to "federal mode" or use an outside key. If someone has hacked the hardware I would be a bit sha...

phrawg

do you know you just answered a 5 year old post

Phrawg

phrawg

Don't think a protective diode but there is a fuse down near
the battery mounting area. A little green thing that stands up
like a resistor right near the contact block assembly. of course
I have slept since I saw one so this is totally a memory job.
Hope It helps. Phrawg

phrawg

Really the huge armpit tickling wide band dipole mounted on
a PS speaker mic has to be the ultimate hamsexy !

Phrawg

phrawg

HMMMMMM ........... VERY Interesting !!!!!

not as much fun as cracking it in a vice

BUT, Much less distructive

How did you discover that disassembly method ? Phrawg

phrawg

I think also after the lock ring you also have a tab to push like a modular phone or cat5 cable connector has then it will pop out. OOPS Wrong. I just looked at one. No tab, just turn the ring about a quarter turn. may have to get a knife blade or something between it and mic body then pull it out o...

Pretty well a disposable item. Although, I have ben known to use
a bench vise in a similar manner to a nutcracker ! squeeze on the
seam and see what happens !!! The cord can be replaced.

The answers all lie in thermodynamics studies and laminar flow
of air over a surface with minimal eddy currents disturbing the
thermal transfer to the airflow.

phrawg

More to be concerned with here. not only the voltage but the polarity. Is the sleve or tip, pos or neg. Size is just that. SIZE! has nothing to do with voltage or polarity. All 3 things must be correct. Then when you have that right, does the power supply have adequate current capacity. We need some...

phrawg

I wrote up a quite lengthly study on this subject a year or 2 ago. Bottom line is FORGET BLOWING air unless it is a last resort. Best cooling is ALWAYS acomplished by DRAWING air across a heat disapating surface so that maximum heat transfer to the air can happen. Properly designed cabinet cooling s...

phrawg

ahhhhh... Audio ! :lol: no seriously, audio to modulate the oscillator. One such function would be to apply audio of the correct frequency to create a test signal that would be used to set precise deviation characteristics using bessel null functions. Or to provide a direct true fm signal for setup ...

simplicity ! band pass cavity= narrow pass of a single freq band reject cavity= notches out a single freq duplexer= allows tx and receive on same antenna of 2 freqs (1tx / 1rx) in the same band diplexer= allows 2 whole bands or ranges to be combined or split from each other to a single feed line or ...

phrawg

I think a lot of it is as I stated in another thread, the "we are god of radio and if it is not made by us and sold to you at an exorbant price it is no good! " and even to the point of ther sales end saying no moto brand, well, yours wont work with it or we will convolute the process of m...

phrawg

Yes it is the same. Phrawg

phrawg

put the battery on the back of the programming interface block.
YES, The radio does need to be powered. You may be
powering the block but it is not passing to the radio.
Use a voltmeter test the block for power out.
I believe there is an internal fuse in those things.
