I neglected to mention it, but Motorola sells a special ceramic metric alignment screwdriver that's tiny for that adjustment. If you use one of your own, I'd suggest that it should be nonmetallic to avoid shorting anything. Since your management should know that narrowband will be required as of the...

If you remove the BPR40 battery, you will see 4 stickers covering holes in the chassis, 3 small stickers and one large one. If you remove the large sticker, you will see two pots, the left one(looking at the rear of the chassis) is the squelch pot(R215). You should at least have a service monitor to...

Scott, have you looked here for the step-by-step procedure?

The GM300s and Maxtracs were designed to automatically back the tx power down as the heat sink temperature goes up, so it sounds like there's definitely a problem with either temperature sensing at the heatsink or the power backoff circuitry is not functioning. When you start trying to use a mobile ...

Does your CP200 have the latest firmware? IIRC R03.07.01 is the current one. There is a possibility that the newest F/W will remember the status of the keypad across a power cycle. If you upgrade the firmware, you'll need to use CPS R05.15.00 or later to read/write the updated codeplug.

Al

AFAIK, there are no parts or service manuals available for the Min V if you're not an FM authorized service facility with the necessary IS test equipment.

Al

I don't know of any programming parameter in a codeplug that would cause what you describe. Are you using the same RSM on both units when you test them? If so, I'd suspect the RSM first. The option select 2 pin on the accesory connector tells the uP in the radio that an external accessory's attached...

Al

Please tell us what version of the commercial series cps that you're using.

Al

I've had complaints on the same noise with that MUC. M used longer life ball bearing fans in that model rather than the quieter sleeve bearing ones.

Al

The best fix is the one that's already been suggested...send 'em back and buy OEM batteries.

Al

Try cleaning the accessory connector contacts with a nonabrasive cleaner/contact enhancer. If you still have a problem with the same error message, replace the flex interconnect between the accessory connector and the PCB or swap the complete front housing(including flex) with one known to be good.

Al

In addition to the above posts recommending the proper opening tool, I'd recommend being very gentle with the latches on the flex connectors...the hinge retaining pins are pretty small and easily broken as are the latch assemblies. I use the chisel shaped end of an orange stick under one end of the ...

The saddest part of all is that Motorola is only concerned about *their* bottom line and shareholders' demands for constant improvement in same. M could farm repairs out to an independent U.S. company, but their profit would evaporate because they can only reasonably charge the customer so much for ...

If price is not a primary consideration and you want good quality with ruggedness, www.davidclark.com.

Al

Most likely you'll find that the factory-installed codeplug structure is too new for your version of the CPS and the CPS doesn't recognize/know how to handle it. The current version is R06.12.02.

Al

Arlo, I believe the 8 pin modular is an RJ45 and the 10 pin is an RJ50. I've never seen a beast such as you're looking for, only female to female 10 pin RJ50 couplers.

Al

It could if there's a film over the gold on the contacts.

Al

If you have some DeOxit Gold or other nonabrasive contact cleaner, clean the contacts on the radio's accessory connector, reattach your programming cable, and try again. I wouldn't recommend using anything abrasive(even a pencil eraser) because the gold's so thin on the contacts that you'll remove i...

Al

I'd recommend that you replace the heat sink compound, because someone after you may use the radio for transmit and experience PA failure(either audio or RF). The M1225 manual does not list any part number for the thermal compound, however every heat sink compound that I've ever seen is nothing more...

Al

The accessory fuse is a Littelfuse picofuse, probably 2 amp and either green or light brown in color soldered onto the logic board near the accessory connector. It's about the size of a 1/4 watt resistor with axial leads. It'll likely be marked with the manufacturer's logo and rating: Look for "...

After completing M's license requirements, people can then purchase subscriptions for any of the software that M offers that is covered by the license agreement. A subscription for any particular software part number is good for three years. At the three year point, you need to purchase a new subscr...

If you have access to the Global Tuner, try changing the baseband offset frequencies. Look here: http://batboard.batlabs.com/viewtopic.p ... and+offset

Al

It's not normal for an M1225 to be in transmit while programming. It's probably getting hot because the transmitter PA transistor is dissipating heat resulting from a long period of high current draw. You didn't state what you're using for programming equipment, but I'd guess that if you're using an...

Have you tried installing it in a Win XP box? See here: http://batboard.batlabs.com/viewtopic.php?f=1&t=97717

Poor receive sensitivity brings to mind the recent FSB describing defective antennas that the OEM supplied with the BPR40s. The antenna stud was too long causing a direct short to ground inside the portable when the antenna was installed. However, this may not apply since you may have checked sensit...

I don't know what the region hack is, but the password bypass for R05.15 Commercial series is at 12B041h, 7509h --> 9090h.

Assuming that your CP200 has older firmware, you can simultaneously update the firmware, codeplug structure, and remove the codeplug password protection by doing a firmware upgrade...I think the newest version is R03.07.01. I recently had to blow new firmware into 4 CP200s that nobody could remember...

Al

What firmware is loaded on the portables in question?

Al

I'm using R06.12.02 under windows XP and I still have table view available.

Al

You could tune as you suggested for minimum reflected power. I'd use an antenna analyzer to get a swept return loss plot vs. frequency or a service monitor with tracking generator and return loss bridge to get the return loss somewhere in the ballpark without risking the transmitter PA health. The E...

Al

Ya, that's the matcher type that you want. EMR Corp makes one too. Insertion loss on either one is quite low at less than .2 dB. The EMR 6550/Z is rated for a little less power and 300-650 Mhz but it's $145 list:

Al

The first thing to check would be the degree of mismatch as Wow suggested. Assuming that it's poor enough to require correction, buy a coaxial pi net impedance matcher from Telewave that will allow you to tune out the reactance so your transmitter will see 50+j0 ohms(no reflected power). The pi net ...

The service manual that covers the AAEN1006 and AAEN1007 is still available per MOL, p/n 6881093C79, $26.25. Since it was designed in the EU the prints in the manual are a combination of English and German - mostly English even though it says Ft. Lauderdale on the back cover of my manual.

Al

Correct.

What David said. I use Norton Ghost(runs under DOS) to image the existing hard drive, sector by sector, to a spare identical HD. Then put it in an antistatic bag for a while. Ghost 2003 which I use has been replaced by Symantec with something newer. With the version I'm using, I can clone the HD or ...

Version 3 FW would be R03.XX.XX. You have R05.08.02, which is not very old. The current version is R05.17.01.

If a telescoping metal mast will do the job, Rohn makes the 20 ft. R-H20, and the 30 ft. R-H30. Tessco sells both of them. The 20 ft. weighs 17 lbs., and the 30 ft. is about 27 lbs. I don't recall seeing any made of fiberglass, but I know that you can have them custom made. http://www.rohnnet.com/ro...

Al

I'd look at pin 90 of the uP with a X10 scope probe to check the level and period(frequency) of the 7.3 Mhz clock.

Al

You have to use a hot air rework station to remove the shield from the uP or ASFIC before you can get at pin 90 on the uP(EXTAL) or the SYN output of the ASFIC which supplies the 7.3 Mhz clock to the uP.
There are no test points where you can check outside of the shields.

Al

Agreed, Bill. It's hard to imagine a situation where the RSS/codeplug selection wouldn't be optimum.

Al

According to the R1225 service manual, the receiver's front end has 3 pin diode switched bandpass filters following the first RF amp. All three have 1 dB bandwidths of 10 Mhz, centered on 151, 161, and 171 Mhz. So the first filter covers 146-156, second 156-165 and the third 165-174 Mhz. The hidden ...

Assuming that you're speaking of receive on the HT1250, I would expect that at 3.8 Khz of deviation, you'd be banging the hell out of the receive IF filters, and I'd expect it to "cut out". The nominal deviation for 12.5 Khz channel spacing in the U.S. is 2.5 Khz, so the occupied bandwidth...

According to my schematics, the option select 1 and 2 pins are pulled low by two transistors on the VA microprocessor card, and these transistors are driven by pins 2 & 3 on the uP IC6 on the main board.

Al

The longest cable that M offers for these kits is 7 meters. The cables are standard 10 conductor flat telephone-type cable. Has anyone tried using a longer cable, say 75 feet, with these kits? Did it work satisfactorily?

Al

Mother M has discontinued them, but if the OP has one with model number AAEN1006(VHF) or AAEN1007(UHF) I have a new one that was never installed, along with the service manual that covers both models. If the model is as I've described above, there is a selectable gain audio amp in the transmit mic p...

Al

If you're using R06.12.xx it works fine without removing the clock battery. The rechargeable LiIon coin cell only powers the clock when the normal battery is removed.

Al

You have to load a pager codeplug or read a pager before the engineering mode becomes available IIRC. Have you done this?

Al

Either 1/4 or 1/8 watt will work fine.

Al

Look carefully at the accessory connector on your HT1250, and inspect for dirt/corrosion. All contacts should show goldplate and be clean. If not, use a commercial contact cleaner/enhancer such as Caig D50. Using a pencil eraser will remove the goldplate and encourage corrosion.
