Hi Bill !
Although it is not intended for public release, I would gladly provide you related information and preprogrammed MCUs, since you are interested.
Your feedback is welcome. Just some patience to fix some bugs, and possibly develop a pcb.

Hi gang! After being much busy, the Corona Virus lock down gave me enough time to continue with the project. I focused on the "Cigarette pack" size and here is the engineering prototype for the GM360/380, 1-line & 3-line display.(Is there a CDM with 3-lines lcd?). I think that it also ...

Dealing with Mercedes-Benz taxicabs, there is no room for a radio, outside the glove box. So, I developed this minimal control head featuring basic functions. Operation: To turn on: press on the knob. Enters Channel Select mode. Displays channel # (0,1,2, ... , D,E,F.). Up to 16 channels. Channel se...

There is software hack, but I'm not sure wether it works or not.
The easyest way is to place a trimmer resistor in place of the big smd resistor near the antenna connector.
The higher the value, the lower the power. Program your radio for 5 Watts and experiment...

Paul

It is a common problem to determine what model is an MCMicro standing on the shelf for long. You have to try various RSS etc. So I developed this little application that lets the radio speak for itself. It should work with all MCMicros, MCCompact, M110, R100, you name it. Only COM1 for now, sorry. I...

A client's Maxtrac300 was brought for re-programming, working OK. After several attempts to program, I found that a transistor was blown in the SCI line. The transistor (Q109?) was replaced and the radio resumed and re-programmed. The radio was reprogrammed with the original codeplug, frequency modi...

If my memory is still intact, MCS2000 is using zebra rubber conductors than flex pcb. In this case you need better sitting (if the rubber is clean).
Check whether the metal tags that support the LCD assy on the PCB provide enough pressure, or if the PCB is not properly seated in the head.

I admit that Motorola was the first car radio in mass production, but according to Harman, until 1949 there were no car radios...

Paul

So, you think that the first car radio was made by Motorola in the pre-WW II era? Perhaps, Galvin was an illusionist, since Harman inc. states that: "Since introducing the world’s first car radio in 1949, Harman has pioneered a continuing series of..." Have a look @ http://www.harman.com/E...

No, It'll be very interesting to explore these chips but I have very little spare time to re-invent the Moto-wheel at this time!

Paul

Hi Bob, thank you very much for your detailed information. I tried several times to re-program my MSF, but in vain. And since the problem persists, I must think of the eeprom, so I'll try to replace the mcu. My TTRC board is much different from the one in the repeater builder photo-tour. It is singl...

I'm using an OLIVETTI 486 @ 60MHz for all DOS based RSS without any problems yet. (some times I have to lower the speed thru BIOS). After programming the MSF. I get this sequence: 1. All TTRC leds on, then "disable" led on. display "---" 2. "TTRC Encode" goes off, displ...

Paul

Also note that the same applies to cheapo chinese batteries. The cells last less than normal alkaline cells and the plastic is worse than you can imagine! I think that it whould be better if they were signed like "Warning - For display ONLY *** DO NOT DROP" In my GP300 case, the antenna ha...

While trying to develop "ham" firmware for the MCS2000, I stuck on programming the custom ICs.
Does anybody have any info on these?

Whewww... C'mon guys, say clearly "THIS IS AN OLD POSTING".
While reading from the start, I tripped over Monty's comment;
It was the "offline" status that kept me from an instant heart attack!

I use for long time these replicas, they operate just fine. Just 2 problems: 1.The hang-up disk will become loose after "strong" use. 2.The spiral cord is of the cheapest copper quality and will break at the strain relief's lower end. It is a very good value-for-money option for personal u...

Paul

Well, I don't think that it's a matter of FCC, since every RSS programmable radio should be illegal as SB9600 is used for the programming of the radio. IMO it's a matter of mom M what features a specific radio should have. As I mentioned above, JEDIs like MC2100 & GM1200 can be literally turned ...

Paul

I can tell for sure that MC2100 & GM1200 and their portable counterparts can be almost totaly controlled via SB9600. By sending an SB9600 command, radio shows "CSQ" (carrier squelch?) just like when programming. Beyond that point, radio is totally paralyzed, awaiting your (SB9600) will...

In order to avoid a possibly long question/answer dialog,
can you send me your codeplug to have a look?

Now we can tell who's from the spark radio era in this board!

I use this one: http://connect.in.com/cable-crimping-to ... 5b5da.html
Got it ,I think, about $15; does a pretty good job.

Get a flat tipped screwdriver, not less than 1/4'' wide, and try to pry it open gently, not to leave heavy markings on the rim. If I recall well, there are two clips on each side, about 1/4 way from the (rounded) corner. To avoid re-engaging of the opened clips and keep your nerves intact, place ano...

Oh, Mike! Once again you prove yourself as the "Ultimate Master of the Syntors"! Don't forget to send me your photo, to place a statue of yours in the middle of the park in front of my workshop, in recognition of your help, all that time... WB6NVH thanks for your reply, it would be more se...

I've got a Syntor X from ebay with missing memory module. Since I don't have a complete radio in my workshop right now, since the schematic is missing from the service manual, and since an extensive web search was in vain, I kindly request you, you good people, if anyone has any info on this top-sec...

Welcome to the club; Get another radio... I stopped selling Waris radios due to "strange" behavior in too many of them; mostly resetting with no reason. And if you have to service it on component level, you'll need a well trained louse to perform the job. After spending numerous man-hours ...

Paul

Thanks for your ideas guys, but I have some good and some bad news.. (By the way, it is a low band II model) I removed the board to have a visual check on the underside and discovered all four 10ohm resistors supplying the driver transistor to be broken and partialy desoldered. This happened due to ...

While reflashing a cdm750, the tuning data were blanked and resulted with a radio that has no tx power.
I tried to retune it with the global tuner, but in vain. No matter what the values of "K & M Tuning" and "PA bias" are.
Any ideas?

My newly acquired CXB MSF10000 when triggered, performs a system reset.
I have a very basic knowledge of it; am I missing something?

Try GM300 ,or, (much better) GM950plus from Australia.

I have used two el-cheapo 400w PC psu in parallel powering a 100W UHF Syntor-X in a taxi co. dispatch, while in an emergency (the smoke escaped from the old psu, Saturday night) I can say that it worked flawlessly for over a month, without any effects on the receiver, and I kept it as a fail-safe ba...

1. remove the head. 2. locate the 13-pin connector that goes to mic connector/on-off-vol pcb. 3. look for the white & purple cables. If the missing pin on the connector is #3, white is #1 and purple is #2. 4. cut them in a place that allows you to reconnect them easily in the future ,if needed, ...

I got a 95% new VHF GP68. My findings: 1. The radio had no external signs of use/wear. 2. The charger by mistake is labeled "MOTOROLA" although I think the real brand name is "MOTOLORA" There are also some very helpful labels in chinese underneath (Sorry, I can't tell if it is tr...

Some years ago, I had built a repeater with a couple of MC2100's, and discovered that this radio was not designed to be a part of a repeater, since no matter what rss I tried, I didn't find an acc connector configuration menu, not even the programmable pin used on GM900. If I recall well, the csq si...

About programming: 1. Keep your hair on (if any left). 2. Take away that sledgehammer. 3a. The academic approach: When you try programming a radio, the following dialog takes place between your radio and the RSS: RSS : Who are you? Radio : I am MCS2000, model... yadayadayada... RSS : OK, take that.....

Paul

Although I have no experience of this rib (I have built my own),
I troubleshoot most of these problems using this simple tester:

Hi all, I need a hi-power lo-UHF radio, Select-5 capable. I know that MCS2000 can be turned into an MC2100 but I don't know if this is possible to the "big one" too. I was also thinking about Syntors & Spectras but lo-spit UHF radios are very rare and the radio must be retrofitted with...

Paul

I will keep my eyes open... I thought that the 9000E was only a 800 MHz model. I check ebay regularly but I could locate only 45W spectras in range 1. Oh, about the shipping cost, I am well prepared to take the punch! The problem is that most sellers don't ship out of ConUS, so I have to ask some US...

At first, don't forget BC-1000/SCR-300; http://www.vk2bv.org/museum/bc1000.htm the FIRST production FM radio ever! I still have a couple of them working, in D-Day condition. At second, you can have a look at the past to tell the future: Back in the 20's and 30's RCA was almost the king of radio whil...

Since it is nearly impossible to find a (Hi pwr) Lo-split UHF Syntor-X (or Syntor or X9000 or Maratrac or Spectra or ...) while Hi split radios are common and lo-priced, I wander if it is feasible to turn a Hi split radio into a Lo split (407-417 region). I'm sure i can fix the VCO, but what about t...

Paul

By adding 2 smd capacitors you can lock in the entire radio band (tested on VHF models) - not a hard job.
If interested, let me know.

Since it is sure that the mcu fails = bad news! :cry: There is no economical way of reading the pre-programmed (actually mask-programmed) mcu. It is also bad that you cannot use an mcu from a 2-chan radio since they have different firmware. If you had the hi chann capacity version, then things could...

I'm not surprized; Among other things, the national distributor ,when I asked for RSS, tried to persuade me that this version does not exist!
Nice idea about the storno forum.
Although I am already registered ther, i didn't think that it could be a site of value.
