I have a project to resurrect some low band Syntor X9000 radios. I may want to build up an ASTRO Spectra A9/W9 at some point. I have three radios. One for my main vehicle, second for a consolette base I am assembling and the third as spare . Along the way, I have been gifted a lot more radios and pa...

"Per MIKE B The C25 tantalum capacitor is a known weakness. C25 can short out which takes out coil L1 and kills the display high voltage supply. However, the backlight is run from the switched battery voltage and is not part of the high voltage supply." Here I am 2 decades later and quite ...

That looks like a VHF range 3 Securenet Saber radio. The top of the radio has funny shaped a secure/clear knob to activate the encryption module in transmit mode. It has two positions and an emergency button in the middle. Rotate that to the "O" position to see if the tone goes away. Turn ...

I have been refurbishing UHF Systems SABER radios for a long time and find that most of them are within 200 Hz of spec. This is pretty good, but they are 2 ppm TCXO's. The regular SABER radios have a 5 ppm TCXO and from the ones I see, they are very good as well. These are surplus radios, probably b...

I just picked up a nice Feb 1988 vintage MX360-S . A UHF Secret Service model with scan and 36 modes.

It has a NLE9010DSP01 DES module installed. Is this a DES-XL module? Date Code is 3-88 so apparently fitted to the radio shortly after shipping.

Did you ever get this working?

Maybe the modulation compensation is maladjusted?

I know this is an old thread, but I have a question. I have an 8 channel DIGITAC sitting loose on my bench, no receivers connected, thus it passes the self test fine but does show the normal fail lights. Is this enough to presume the AGC chips each passed in self test or do I need to have a status t...

What Bill_G said. spot on. Your repeater has desense and it is hearing its own transmitter. Either faulty antenna system or duplexer. Do the tests into a 50 ohm dummy load to rule out the duplexer. The antenna could be too close to other electronics resulting in a mix of signals or noise. The echoin...

I know this is a very old thread, but I have never seen one of these and would like to find one. Is there really such a thing as a Saber X transportable? Pictures and part numbers please? I should clarify, we have all seen the silver Zero Haliburton cases with a vehicular adaptor and power amp. I am...

Have you checked the deviation balance? AKA modulation compensation.

Uniden BC906W wireless microphone $50. Amazon. Of course, Motorola and Pyramid have pricier solutions. You will have to work out the pinouts to wire it up. 300 ft is the claimed range.

OK; I am working on my "fleet" and I have this one UHF SYSTEMS SABER III that is exhibiting tinny transmit audio. At first I was testing in secure mode (DES) and thought it was the NTN5835A DES-XL module that I am running with the XL disabled, but then I compared in analog FM mode and sure...

Is there a concise document that compares the different CON firmware versions of the Systems Saber product? My RSS gives a choice to upgrade the CON and I would like to see how certain features would be affected. Thanks

31003 is the Tenergy part number. I used a medium sized NIMH Intrinsically safe battery case. The weight is now several ounces lighter . Obviuosly no longer IS Rated, but works fine. The particular charger Chip is available on a development PC board and starts charging when the battery is down below...

I used a two cell protected pack from Tenergy about 2200 mAh 18650 cells. No need to step down the voltage as it is a good match. Because Motorola uses a diode to isolate the charging pin and I could not afford the voltage drop from the Microchip 2 cell charger, I used a reed switch and put a strong...

I have done it, it works great! I had to find a proper Li-ion charger chip and modified a pocket charger to work with my new 8.4V 2 cell Li-ion batteries.

I think I also recall seeing a connection mistake in the line drawings for one of the SINAD procedures. There is a Yahoo bulletin board for the HP8924 and HP8920. If you sign up there, you can download a live video I posted there which shows hthe 8920 being used for actual testing. It is a bit grain...

What frequencies are each hospital operating on? Is it possible that now that the repeaters are linked, you are noticing adjacent, or near adjacent channel interference that was not occurring before?

RFI-EMI-GUY

Are you testing the radio through the option connector and proper programming and servicing cable or "off the air" using the antenna? If via the antenna, there is a possibility that the antenna connection to the mother board is poor. It is via a spring clip. It can get noisy or intermitten...

I need to build a cable to load my Systems Saber from my KVL. I have the NTN5664D Hirose adaptor and a Hirose 6P mating plug. Now I need to modify one of my existing but obsolete KVL cables to match the pins on the Hirose adaptor. Yes I have been to the bat labs site (below) and I don't see a TKN853...

Holy cow does that bring back memories. :D Somewhere, probably buried under a ton of things, I have one of those nylon telescoping plungers with the spring inside, In fact I recall it is inside a small plastic container with some of those tiny fuses for the HT220 or maybe HT100 (I had one of those!)...

Can anyone tell me if there is any different firmware in the SVR214U (14 channel version) than the SVR200? I have never seen a 214 model out in the wild, only on the Pyramid website (long gone now). The circuit board appears to accept a BCD panel switch. The service manual only lists one CPU model t...

Well I went with my gut and opened to look at the contact assembly. The design is funky. If the spring leaves are not bent enough, when assembled they catch on the bottom of the plastic channel they operate within. If you pull the PC board up so they don't catch, then the battery contacts don't make...

1) I just bought what appears to be a new old stock 1989 vintage NTN4734B charger to give my NTN4734A a break. I noticed a few things different off the bat. 1) The STANDBY LED in the upper right corner is more orange/green than the Yellow of the "A" version? Weird. 2) The contacts seem to ...

Hi All: I have just posted this evocative topic to encourage experimentation on Motorola Systems Saber radios. Those familiar with the Systems Saber radio are aware that a fraction of the interior cubic space is occupied by either a SECURENET module or a bypass module consisting of a wire. Now due t...

Has anyone experimented to see if SYSTEMS SABER complies with the SB9600? I have some ideas for the SECURENET module space. The data bus, busy and a slew of other signals are available for the SECURENET as well as pins to the accessory port.

Thanks; Yes the W&W was a disappointment right off the bat. A bit to large in width leaving a gap at the latch. And the battery has an early death. The Primecell repacks, are dying but have a better last gasp than the W&W. If I buy some IMPRES batteries, will they work at all in my old charg...

I am shopping for a couple new SABER batteries before the hurricane season. I have had bad luck with W&W. The battery barely lasted a year under extremely light duty and the housing fit was cheesy.

Hi Slim Bob; Are you saying the 200K Ohms for a DES-XL and 29K for DVP modules are normal? Did Motorola intentionally make the DVP draw down faster? I always wondered if you could defeat the zeroize function by installing a large capacitor on the B+ line. Now maybe it seems a bleeder resistor inside...

I guess I will have to open these up and check the PA modules and the secure modules. Now I have to pull batteries of not in the charger.

RFI-EMI-GUY

True; the capture ratio is degraded as well. Yes digital starts looking attractive when you are forced to narrowband. You will have improved range, though arguably the voice quality is not the same. Motorola would call this result of "Fait Accompli", or "a done deal - money in the ban...

My first thought, but the service manual implies that type of failure is measure above approx 105 ma in standby. This is powered off, and much smaller drain 0.5ma. I will peek at the schematic to see what parts hang directly on the battery + line. Hoping to interest some others to measure their radi...

When you perform 12 dB SINAD testing, the signal generator is adjusted to 60% system deviation (Per TIA/EIA 603D), So for a 25 KHz system running +/- 5 KHz deviation, you set the 1000 Hz tone at +/- 3.0 KHz. For a 12.5 KHz system, the deviation is +/- 2.5 KHz, so the tone is set at +/- 1.5 KHz. This...

Apparently Motorola made a VHF "DVP" HT-220 at one time. I found a service manual for just such a radio. Where the PL board would go, a small PC board with gold flat pack IC's was installed. There was a CVSD chip, some discrete logic and three or four BCD rotary switches under a door. It w...
