Busy Channel Lockout?

Bigred

I don't think it was a community repeater, else why would the F!/PL, F2 control and guard tone modules be in it? Sounds like it was some sort of base station originally and converted to a repeater (RCB vs. RTB). Yes, but it also has the multi PL encode and decode cards. I will agree that is an odd ...

Bigred

On a Micor station asserting PTT usually does not activate the PL encoder. Since you have a community repeater style station, this is especially true as the one of four PL decoders needs to respond to select the correct corresponding PL encode reed. If you only need one PL then you'll have strap a s...

Is it me or are the elements wayyyy too short for VHF?

Bigred

OK OK, I know I'm digging up a ripe thread but this is for those in need and have stumbled here on a search. I have just gone through the circus of trying to connect a console to a remote radio site (not a MIP 5000) and passing multicast packets. We have had our wireless broadband provider and a hir...

Bigred

I'm interested in your usage scenario too. It sounds like you might be better off using a portable interop gateway and three mobile radios. Cleanest way to go. Could do 2 XTL's and the SVR if it compatible with the gateway. Down and dirty you could probably combine the RX audio (with caps in-line f...

To get this to work, dispatch will have to have a remote also. Consider one that fits the day to day operation like maybe a gooseneck mic and a footswitch instead of a handset you have to pick up. Dispatch will be heard through the repeater. I was going to give a "?", but after re-reading...

Bigred

Or if you want cheaper, go with a RICK or one of the many cables that serve the same purpose. When audio delay is needed I use the RAD board from Arcom. Easy to work with and splice inline.

Bigred

You need to separate the HT from the GM300 to test through the repeater. Better yet test with a buddy that is away from your location.
Look up "receiver desense" for an explanation.

For CPS programming all the adapter does is add a jumper between pins 1 and 3 that is not there in the mobile cable. You can make something that is a lot less $$$ than what the adapter sells for.

Bigred

Not sure what you found but the adapter is RJ-45, fits on the end of the mobile cable and then plugs into the mic jack.

Bigred

CM series also needed the FKN8096 programming adapter added to the cable. Modding the cable was also possible.

Bigred

Correct. Connect Plus CPS has six GP inputs. Tried all six as Ext PTT and pin 17 would not key radio. Unless inputs map to different pins???

Bigred

I tried to do a local remote on a XPR5550 with connect plus. Could not get the EXT PTT to work off of the accessory connector. If the radio was switched to a conventional zone it worked. Seems like the option board doesn't recognize EXT PTT. I gave up. I would investigate this on the 4550 before any...

Don't feel bad, happened to me last month. Updating a XPR8300. Downloaded the intermediate FW just fine but when I tried to get the latest it always 404'ed. That was on site using my Mifi. Later that evening I tried on the home cable and it downloaded first try. Just shrugged it off and returned the...

Bigred

Yea, you're right. The Sentri-voice.

Bigred

MSR's do get wonky over time with all the mechanical connections. Probably time to do the whole enchilada. Card edges, channel elements, pots, etc. Scrub everything down with contact cleaner and then secure it with deoxit or stabilant 22. May save a mountain top trip or two.

Bigred

For a simple task like that I guess you can get the Midian to work the way you want. I've never tried the VAE-1, prefer to use a Zetron model 18 instead.

Bigred

Had a Maxtrac once eating diodes. Was on a short bus with a wheelchair lift. The radio was wired too close to the lift solenoid. Re-routing power to battery fixed that.

Anything funny going on with your vehicles electrical?

Bigred

Had the pleasure of talking last week to Michael Marzouk of Raven Electronics. They are OEM suppliers to many manufactuers including Motorola. They produce a black box that can be custom configured for just about anything you can think of by their engineers, including inter-op to the PTT app ESChat ...

Bigred

For set ups using a model 18, always used a mid power mobile and never tried with say a portable or a smaller OEM type transceiver. Sitting idle it would consume around 5 watts of power and jump to 30-40 watts for that rare transmit (low power TX). Not too bad for a solar set up. Bill G's suggestion...

Bigred

I've always used Zetron's model 18. Add the RF engine of your choice. Hardest part is sizing the solar to run it. I have installed them as tank fill, remote gate controls, intrusion alarms etc. Works fine.

Bigred

You're assumptions are correct. I have one XPR8400 using a Henry amp and it plays just fine.

Bigred

No RX audio could also be the radio was set for handset and there was no mic or mic wasn't on hook. This would route audio to mic connector pin 8 only. When you were pressing buttons did you happen to get into the user menu and change things?

Bigred

Power supply with a huge transformer. Real nut buster for sure. The power supply itself is a ferro-resonant type which means it is self regulating and no way to adjust it. 15 plus volts , the main current draw to the PA, is normal and provides overhead to run 13.8 volt regulator that is used in the ...

Bigred

Well what is happening or not happening for you. The pins listed are correct and should get you going. Double check your cable wiring. Make sure logic direction is set correctly in the RC96 for COS. /\/\ radios provide the proper logic levels (5V - 0V) by themselves so make sure there are no pull up...

Bigred

Tnx RFguy, that be it.

Bigred

Local extention mic, more than likely home brew. Used to make them all the time. Very easy with the panel mount Motrac/Mocom mic jack.

Bigred

Thanks and I understand all that. This is an existing system that will be upgraded. Only three new dorms being built will need the speakers that go to full on alert. I found that Atlas Sound makes the volume controls with a bypass relay installed. Will still need 4 wire cable to the speakers but tha...

Bigred

Does anyone know how those step attenuators work on a PA system between a 70 volt amp and the transformer at the speaker? What I want to do is allow the user to set the volume to a speaker (70V) to what they want, even off. But in case of a station page, have the volume control bypassed and apply fu...

Bigred

Do you have a preselector? Maybe that needs attention.

Bigred

The OP mentioned turning down the power to 25 watts. The only narrow UHF GM300s I've ever had my hands on were M04's set at 2 watts for LPI service. High power units are much rarer. If they are indeed factory narrow radios, then I capitulate.

Bigred

And somebody better tell him to chuck the repeater and acquire one that's legal.

Bigred

Pretty simple speaker panel. Stereo amp and two speakers, four mixed inputs per side. All the needed info is silk-screened on the back. If you need cross mute you'll have to play with the inputs to figure it out but easy enough.

Bigred

Plus one on a small console. Simple headset to radios can be found here:

http://www.radiomate.com/

but you'll have to roll your own switching for multiple radios. I've done it with a rotary switch.

Bigred

In my work van seems like the two or three I always need are riding on the dash. The next dozen that are common hang on a cable rack with my test cables and secured with small bungees. All my seldom used/historic cables are in marked zip locks and separated by manufacturer as mentioned. This fills a...

Installed a VHF EMR bda and used their antennas which are nothing more than a half wave dipole, however a lot more low profile than the above suggestions. Model I believe is B2H3/Q5BM. Funny though, couldn't find specs on it from EMR's website but the UHF b/w is listed as 20 mhz so maybe about half ...

Bigred

OK, so what I'm reading here is you're looking at the spec a hooked to the receive of the duplexer, filters etc. and not really seeing anything popping up on your input which is good. Now my old IFR 1500 won't see much past -100 or so it's missing quite a lot. Success there is how low your spec a ca...

Bigred

The 4010 has a back-up battery to hold the configuration data. If it goes you loose it all and the console either displays an error message or just plain wigs out. Easy to find and check, should be 3.0V or better. Battery should be replaced every 4 to 5 years.

Bigred

Motorola never made or supplied a relay box. Some were homebrew and some were produced by third party companies. We used one made by Wired Rite that came with a control cable and DB-25 that was plug and play to the aux switch card. Although they still make relay boxes, nothing specific anymore to S9...

Bigred

Monitor button would also defeat sel call if for some strange reason you have that enabled.

Bigred

Maybe the transmit power was cranked down in RSS? Did you check?

Bigred

The B+ power for the PA comes straight from rear connector and is soldered right to the PA pcb. Methinks this is an added power wire take-off for something else. Where does it go? My experience with a GM300 is if you lose B+ to the PA it will barely tickle the wattmeter. Do you have B+ on the final ...

Bigred

We've been trying Wave from Twisted Pair. OK, better than what Sprint is squeezing out now or miles above Zello. Got to say though, for however aggravating Nextel was, their backhaul worked. Waiting for hands-on for TRBO-Vui.

Bigred

Common. Don't know how many guys replaced the switch, but I found it just as quick to clean them. Never seen any just plain wore out. You can hose the switch down with contact cleaner whilst exercising it and that will cure your ills. I however like to disassemble it and give it a good cleaning for ...

Bigred

Model 38 sounds "bout right. You would have to go in and enable every PL/DPL "user" to log them all. Kinda painful with a klunky terminal program. I'd go with the CSI flex myself.

Bigred

There is a small "U" shaped rod that fits into a groove of the switch plunger. Remove the rod and voila, momentary.

Bigred

Not sure what exactly you're trying to do here. If the Ritron Quick talk will not work for you (freq limit), Midians makes a squawk box complete with DVR canned voice, you'll just have to add your own radio to it to make it all work. http://www.midians.com/html/specspage.php?pline=Alarm%20Encoders&a...

I have experienced almost the same thing with SM-50s (although not a FF display as they have none). Using my trusty original 486 laptop that is close to 20 years old. Cloning a SM-50 will brick it (can't remember exact symptoms), but it won't work right and I can't read or write to it anymore. I've ...
