I would bet the radio is telling you that it has no encryption key loaded. Doesn't matter if the channel is simplex or duplex/repeater. That's the way encryption works on almost every other product. Either load a valid key or remove encryption from all channels formerly programmed to use it.

Karl NVW

You ought to be able to cross-tie between a CCGW on the M side and the equivalent MACOM or Harris console interface on their side. It's a simple 4-wire audio plus E&M pipe for each pair of talk groups. No crossover of unit ID, other signalling, or voice encryption. We deployed it for Oakland Cou...

Maybe if you told us what radio or front panel assembly, someone here can help you find the VC pot you need.

Karl NVW

Yes, they are color-coded. Unfortunately I don't have the table handy.

Karl NVW

Confirming, the GM1200 mobile transmitter is designed to a 20% duty cycle, maximum 60 seconds transmit followed by 4 minutes receive. The heat sink will not even provide sufficient cooling during 50% DMR or analog transmit duty cycle.

Karl NVW

That one did not ever exist for NAmer.

Karl NVW

The P25 vocoder feeding audio to the telephone interconnect should have its software version upgraded to match the APX8500, to ensure there is no frequency translation of the DTMF tones.

Karl NVW

The A version HMN1090 microphone did not have an orderable option to allow 'Hot Mic' operation. This would have required a different circuit board which would automatically have been up-suffixed to a B version model. The B version and later HMN1090 microphones do include the jumper which allows a ra...

Be more specific - "Still having issues" doesn't tell us what you are or are not hearing, nor your expectations.

Karl NVW

You should need only the QCII A/B function set for the tone pair 143/142. Sounds like Napa County CA first wakes up the entire stationhouse with QC2, followed by a 4-digit DTMF for each piece of responding apparatus.

Karl NVW

Yes, that certainly would do it. Glad you found it and know the effect of pre-time delay. In general it's not wise to mix conventional analog and DMR in the same scan group.

Karl NVW

This is not a definitive answer, but I would suspect the radio is first expecting to receive an active talk unit or group ID from the outbound channel of the DMR infrastructure, and the software times out after 3 seconds of 'DMR network not found.' You say that your radio is programmed on simplex on...

Karl NVW

I remember that Channel Announcement did require a specific system version or later, but I don't recall the first capable version number. It should be noted in the material your search will bring up.

Karl NVW

" I assume Maxtrac, MCS2000, LCS, GTX, GM and CDM radios are all interchangeable...both the white and black type. "

We are telling you that the assumption on your part is not correct, and may cause serious damage to the radios or microphones.

Karl NVW

Not sure what you want to accomplish with that single piece of information. The radio will remember its last active site before logging out and powering down (so that it can do a rapid restart) but that's almost never the site where it last affiliated to the system. Subscribers can roam between site...

Karl NVW

I can confirm that Radius 1225 Ver. 4.0 Radio Service Software (aka RSS) is absolutely NOT the same as CPS R04.00.00

Karl NVW

Or lift them out of the pocket briefly every three months. NiMHs and LiOns don't need to be reconditioned after 30 days of trickle charge. When in doubt read the battery and charger data sheets.

Karl NVW

With the right station programming options, COR changes polarity to become Rpt PTT which also includes a hang-timer value. And if you are building an interface, 4N35 optoisolators are ideal for polarity shifting.

Karl NVW

And to answer the 2nd part, NO, your radio does not need the orange lead unless you will be transmitting. Green lead fed from +13.8 battery, orange from Ign Switch 13.8 VDC. Ground is returned back to the radio drawer within the control cable - helps keep ignition noise out of the optional accessory...

Karl NVW

I had a hunch you had already looked through the new groups that emerged when Yahoo folded their tent. If any members of the old MW800 Yahoo group do stop by, particularly the old group owner, they can get in touch with you by email. We've bumped this topic a few times already.

Karl NVW

For the second half of your query, it should be relatively easy to find out by searching on Groups.io for the text string MW800 in the group name index (also try on Google Groups). I wouldn't want to deprive you of the valuable experience of using an internet search tool. You may find some other top...

Karl NVW

Any reason you can't record your signal from the wireline remote output? Audio at that point will be squelched when the carrier goes away and will have the PL/DPL signalling removed. It's also run through a de-emphasis filter to provide a true reproduction of what went into the transmitter at the ot...

Karl NVW

The wireline card is for standard 2-wire or 4-wire tone remote control using the station's built-in controller. The Tx Aux Input on the station alignment screen is greyed-out because it is not adjustable as currently set in the code plug. I suggest you use the RSS built-in help files to determiine w...

Motorola single-user repeater stations equipped with PL and DPL send PL/DPL through the drop-off hang-time interval since the MOTRAC stations of the 1960s, and Quantar repeaters stations work the same. The only exception is with multi-user "community repeater" stations. I'm not aware of an...

Karl NVW

Just confirming, both the RIB and the cable are third-party non-Moto hardware, and your CPS is the very last version. Very few people here can vouch for their suitability. As I recall, some old versions of ASTRO CPS won't do a one-hop upgrade straight to the last version. You might need to first upg...

Check to see whether the VIP pin is supplying A+ or switched ground to the relay. A simple relay wiring schematic should be in the XTL manual.

Escomm has correctly restated my response to your original first question. Those portable and mobile units can decode and display the incoming emergency IDs, but they do not include hardware or software to send an acknowledgement message back to the unit which declared an emergency to stop alarm tra...

Karl NVW

The Emergency Button was not designed to function as a peer-to-peer portable or mobile alerting system. If you are sending the alarms to an MDC "H-box" alert console or to a full dispatch console, that console will sound its internal alarm and transmit an acknowledgement burst back to the ...

Karl NVW

Did you try using orian ginal factory-legit software package installed on the correct vintage PC and connected to the radio via the proper RIB and programming cable? Dosbox and knock-off RIBs, homemade RIBs, or ribless were not factory supported.

Karl NVW

If your spanner tool is known to be newer than HT200 / HT220 portables (early 1970s), it could also be for MT500 or HT90/440 a decade later.

Karl NVW

Run the DBO per the FullVision manuals. That one step should noticeably improve your query response times.

Back (a couple of decades ago) when Quantar stations were still in production and orderable, the WildCard interface was an extra cost option, including some additional interfacing hardware and software. Does the physical documentation for your specific station indicate that the WildCard option was o...

Karl NVW

Any chance the target radio was fleet-programmed by a previous owner using a security ID button?

Karl NVW

As a recent ex-Mo, I can't answer your questions or discuss details of specific security methods that might be usable. I will only say that your general security analysis is reasonably accurate.

Karl NVW

An internally programmed unique ID field might also be shared, in order to provide positive verification that the sending radio is indeed authorized on the system and carries the other detected unit ID. Different network security management products may do that in different ways.

Karl NVW

Two different ways to express the same amount of impedance mismatch. Some folks like to measure reflected power in absolute watts, others like you prefer the easier add and subtract when looking at the more complex system view. To-may-to, to-mah-to, it's all sauce.

Karl NVW

Most users elect to field-add the encryption capability into their existing radios acquired in the last several years, which would use those existing IDs and should not require extra system ID licenses. That would allow your fire chief vehicles to talk encrypted on fire or law enforcement TGs as you...

Karl NVW

You'll also need either a duplexer or two antennas at each end. Without those the far link end cannot interrupt the local link end while it is transmitting.

Karl NVW

What is the manufacturer name shown on the front panel or serial number tag?? That model number does not appear to be valid for Motorola Communications test equipment products.

Karl NVW

Should be obvious that the op name OP04 cannot be duplicated at the same site. It's similar to assigning the same IP address to both CPUs. That's why they are almost always numbered sequentially as OP01, OP02, OP03, etc.

Karl NVW

It doesn't always require a set of manuals to fix an ASC issue. You could simply describe the problem and ask your questions.

Karl NVW

My fault, I didn't spot that earlier.

Karl NVW

I guess someone should point out to Ernie that the HLD8029 board is for a VHF radio, while the HLE8300B board is for UHF, so MOST of the component values will be different. Radio service manuals for the GM300 family do include schematics as well as images of the PC board foils.

Nigel, your description of the damage sounds like your power mains suffered a severe voltage surge. It's good that none of your radio equipment was connected when you powered up the supply. Google is your friend, but I haven't found a manual, just the assembly: https://www.radioworld.co.uk/mydel_mp-...

I'm not taking pot shots at anyone, just pointing out some incorrect information in your comment. These are discussion groups and I don't mind discussing this topic.

Fineshot1's comment is itself incorrect. For background, I spent 43 years at Motorola Comm/C&E/Solutions, along with other fine RF engineers who contributed to the well-known R56 site standards and practices.

Motorola's field organization doesn't recommend use of ANY cabling in the duplex RF path with a braided shield. That goes double when folks are using a notch-only duplexer instead of a properly selected true Bp-Br or bandpass-only model, especially on a multi-user RF site. I'm not saying that you ha...

The APX radios internally include matching circuits for the antenna mounted on the radio frame. Motorola's portable radios have been designed that way since back in the days of the HT100 and HT200 Handie-Talkie portables.
