Just use the tip of a mini-flat bladed screwdriver. Carefully pry a bit of the brown glue up and the rest will pull away enough to unsolder the crystal.

Bat2way

What was your solution? Just curious.

Bat2way

As stated above, a simple fix, replacing the caps on the final input PA. Always turn the power down to 25-30 Watts or less and you have the option to use it as a driver for a TPL-type PA replacement if you need the extra Watts.

Bat2way

Is there some design reason why the PTT switch has been made so hard to press on these units?

Bat2way

Just stay doing what you're doing, and you'll be better off. The local radio shop is going the way of tube testers in drug stores.

Bat2way

We've also used "boat cable" which has a white covering with black and white wires.

Bat2way

It's easier to just take the mic apart and disconnect the black wire going to the rear weight contact and solder it to the pad that the spring connects to. This is presuming you have the black-style mic HMN3596A. Other mic styles would be along the same lines.

Bat2way

Sounds like you'll need the RSS to do a complete "replace PA" sort of tune-up of the power out parameters.

Received a call this morning from a customer that I had recently filed an FCC license application for. He stated "I received a letter from the FCC..." and you know the rest of the story. After explaining the scam to him he said he almost sent it through to be approved for payment but calle...

They are easily decoded by off-the-air monitors.

I understand the reasoning for the PW, but still sounds like a conflict of interest.

If one thinks that as of some future date all users will compliantly throw out their existing equipment and purchase new, they are seriously delusional. Of course the dealers and manufacturers are pushing this, sounds like an easy pile of money. Yeah, and mentioning the FCC fines for non-compliance ...

For what an MSS will charge you ($125.00+), you might as well sell/trade with problem noted to a tech buyer and get a replacement.

Bat2way

Does all this extra work/future reliability worries = the cost of an OEM battery? If I was giving this to a customer, for instance, it would have a new OEM battery and fuggetaboutit.

Bat2way

I've had just a few filter crystals, either Y51A or B go out = very poor sens. Check your junk pile and substitute. Very easy to check with a RF millivoltmeter and input signal.

I just thought "codeplug error" was an easy way for the Mexirola Depot to make some money.

EWA may have a quick response for you, as they deal with this stuff daily. They have been most helpful on my questions.

Gotta love the SP-50 for repeat business. The Visar is an oddity around here.

Not something I ever wanted to see on my bench either. Hate to see good money wasted on these units. We have junked plenty, replacing them with Kenwoods. ZERO problems now.

Bat2way

It was more on the line of an "Industrial Dispatcher" model. Lots of info on the search engines about it and motorcycle use.

Bat2way

These units were made by Instrument Associates Inc (IAI) in Memphis, Tennessee.

If the speaker up front is being turned off anyway because it's too loud, remove your hook-up to the radio speaker and use the options plug low level disc audio output (pin 11), or just put a local remote up there. This allows the remote speaker volume to be adjustable and independent of the radio v...

What brand of crimper is used ? I went to soldering due to previous post on here that stated crimping could ruin the female connector on the radio. The damage caused to the female connector was always attributed to an improperly crimped center pin (i.e. crimping tool not at a 90 degree angle to the...

For those of us who actually have to repair repair radios..........

I've used junked units for parts. Replaced a bad PA from one with no problem.
The PA's Mitsubichi part # is RAO7M4452MS

Remove the bottom dash trim and the side cover where the fuses use to be. Reach in and release the four retaining plastic clips to pop out the headlight switch module rearward. The two cables can be removed (one is in a dummy clip) allowing you to easily work on the module out of the vehicle. Bring ...

Sounds like the contacts going resistive with current flow. I've already heard about Chinese metal used in various parts (even truck engine parts) is not up to par. Hope that isn't the problem there.

Just get OEM and forget about it. It's not worth the hassle.

Just replace the two 56 pf caps at the input of the final PA transistor. Clean up the input/output with solder flux removing the excess old solder. You do not have to remove the Collector-side output caps (with the green stuff). Just clean up around them and the base and collector tabs making sure t...

Received a CM300 back but with someone else's engraved cover on it. Considered that "normal" these days.

Try checking with a CB shop. If you have one in your area that carries "Workman" accessories, they make a compatible plug with 10 gauge wire. Bypass the CB shops and double your purchasing power by checking sellers on FleaBay or if you want to buy on a wholesale level ($70.00 min, I belie...

Bat2way

Are you saying you're splitting the transmit out into two separate runs, or just using the tx power out as a reference check of each line's condition? If so then, are you simply running separate tx-rx antennas with no duplexer? If using the tx power test method, you need to measure the power at the ...

Bat2way

Just requires a bit of technique and finesse on your part. I heat a solder blob over the six leads at the same time causing the switch to drop out by its own weight, basically. There are exceptions where someone soldered the guide pins to the circuit board, and others where you can carefully cut awa...

Saw this recently on a web site selling far-east Asian antennas:

27MHz Two-way Radio Antenna, Ssuitable for Trunking System Model Number:CB-1105

Bat2way

One of the things overlooked is that if you have a frequency resonant feedline you'll never get a good match, so if all else fails cut the line by a foot or two and put on a new connector and that should clear things up. I've seen where the coax had been cut short in a previous install for some rea...

Every few years there is a new Motorola strategy, and a few years later found to be a dud. Motorola lost focus on everything but self-promotion of their corporate people and sold out all others below. Who enjoys supporting such a badly run company?

Bat2way

Exactly why MSS's carry multiple radio lines. Motorola works like the politicians inside the beltway...no touch with reality.

Bat2way

You can buy parts all day through MOL, but if your account isn't an "Authorized" service shop, you're granted limited viewing permissions.

MSS sales people sold the P1225 as a unit "mandated" by the FCC....etc...etc...

Forget about ANY mandates coming from the FCC about you throwing away your 12.5kc split radios. Still going strong here with the 25kc stuff.

Bat2way

You can chase these problems all day, just make room for the TLN5277B and call it quits.

Bat2way

Micor PA's are better off in the trash. You can spend the same money in a modern replacement (TPL) and be better off.

Bat2way

Actually, the squeak is called a "Motion Approachment Alert Device".

Bat2way

So motorola went to an "idiot-proof" design? Well, design still didn't help a customer here who constantly had antennas being switched between HT1000's and HT600's and could not understand why they didn't work. Then there's the user who insisted that their antenna had to be tightened with...

Just had a 10 year-old GR500 repeater in for no Tx power and the PA was burnt up beyond recognition. Fortunately, having two GM300's in the box meant I could just swap, reprogram them, and reduce the power out to 30 Watts.

Cause of failure: TX programmed with no TOT, and a stuck mobile mic.

Bat2way

It'll be another pitch from salesmen saying you "MUST" buy a new radio, just as when the P1225 came out. This is the last thing I would worry about in RadioWorld.

Bat2way

Made another trip to the UPS store shipping out another busted up CP200 to the Mexirola Depot. As usual, it had been dropped, landing on the antenna, causing no tx power out, breaking the internal connection of the circuit board to the antenna jack. No fixing that. Otherwise, it's the POS speaker-mi...

No effect here. Never had a desire to mess with Vertex and Motorola has just lost focus over the years.
