So - if I'm hearing you correctly; the system will not allow duplicate ID's? How does the system know the difference between my portable and my mobile if they are using the same ID?

I guess for every 10 things you think you know, there are 20 that you don't.

Well - my ID couldn't have been zapped, cuz my portable works fine.

The reason this is so perplexing is - the code plug seems to be correct; the radio TX's on simplex, and it receives and tracks just fine.

Could it be something to with the way I remotely mounted the radio? Maybe a cable issue ...

Yes - I am an authorized user on the system. I am using the same ID that my portable has been programmed with.

This may or may not have started back when I installed a TX inhibit switch. I had to move a few zero ohm resistors/jumpers around on the back of the control head (remotely mounted radio ...

For some reason my 800 trunked Spectra will TX on simplex, but will not TX on the trunked system - why?

Everything in the programming looks perfect, and for all intensive purposes it should work, but when I key the mic... the radio makes about 6 attempts to affiliate and them gives me the steady ...

I appreciate your input and concern, George, but the fact of the matter is we are losing one to two Spectra radios a week. I am merely attempting to get these radios back up and running until we can get XTL5000 replacements. It takes time to get these radios ordered, shipped, sent to county radio ...

I have a gang charger for the MTS2000 portables that is not working correctly. When you place a battery into any of the cups, the three LEDs light in sequence (yellow-red-green) and then the red begins to flash.

I have given the board a good looking-over, and can not see anything burnt or missing ...

Thanks, Bob!!! I really appreciate your non-opinionated help and advice.

What boards can you swap between different Spectra radios? For instance; can you take a command board or RF board from a UHF Spectra, and put it into an 800 trunked Spectra? I have a few Spectra's that have bad/unrepairable RF and command boards, and I was wondering if I can purchase unlike Spectra ...

Can someone tell me what would be some probable causes for the "FAIL001" in a Motorola Spectra radio? Is this a problem with the RF board, or the command board?

Also, can someone tell me where all of the programming information is stored? i.e.: Control channels; frequencies; PL's, etc. Is this ...

Where will I find the date code?

Ok, here's the skinny. I have inspected two of the radios so far, and... It’s the dreaded cap problem. They have managed to leak onto the PC board and ruin some resistors on BOTH sides of the board.

I believe the RF board on the first radio is not repairable, but the second one may be saved. I'll ...

Would it do any good to program in the control channels and see if I can hear them as simplex channels? Or am I just going to get an out of range display?

OK -- the trouble that we are having with 75% of the radios that we've lost seems to be a synth board problem. The symptoms are -- the radios display the "Out of Range" error, and when you attempt to TX on the radios, there is a high pitched wine (feedback) that is emitted from the radio.

Could ...

It would have been helpful to know before I asked for help, huh? I will get the details on each of the radios and get back to you.

Thanks!

In the past week we have lost 4 Spectra radios in our patrol cars. They just quit working. Could it be the dreaded capacitor time bombs? If not the caps, then what? Any one out there experience this type of problem? If so, what ended up being the cause? Please share!! We only have 30 more radios ...

Great.

Thanks for all your help. I apprecaite it.

I'll post the results here after the repairs.

No, I haven't. Where can I find more info on changing these out? Any ideas?

Thanks

BMW FREQ

Ok, here's the latest.

I was so disgusted with the radio that I didn't power it on for a few days :x

Well, I decided to get the old laptop out and start tinkering with it again, so I powered the radio on and it's as if there was never anything wrong with it :roll:

It RX's and TX's just like it ...

Well, thanks to Bob and the schematic that he sent me, I figured it out and it works beautifully.

I mererly located JU1 and JU2 on the PCB. I removed the zero-ohm resisitor from JU2, and shorted the solder pads of JU1 together, and voila! I now have a switch that lets me enable/disable TX any time ...

I double checked, and that WAS the number of the actual control head board.

Do you have any info regarding the jumpers for any A5/C5 control head boards? That would at least give somewhere to start.

I think I may just have to get out the DVM and start trying to determine on my own which resistor ...

Any luck yet on the X-Ray view, Bob?

KD6HXH

I have a remote mount Spectra C5 that I would like to utilize the internal PA and A/B speaker output on, but I can not find any info online that is explicite enough as to how to actually go about doing this.

I need to know what the actual wiring hookup is with respect to what the pinout would be ...

HLN6337D is the HLN number of the control head board that I have.

Thanks for all your efforts to help me out. I really appreciate it.

KD6HXH

Well, I took the control head out of the dash, and gave the back of the control head a good look-see, and for the life of me I was not able to find ANY jumpers.

Are the jumpers in fact located on the back of the control head? Or are the jumpers on the radio drawer?

Now, what is the possibilty that ...

A5/C5 control head.

Well, my radio is a remote mount, BUT, I have already tried connecting the orange wire to the ignition and the green directly to the battery. It didn't work. Unless both the green AND orange wires were both connected to a 12v positive source, the radio wouldn't even power on.

Now, as mentioned ...

I have a Spectra radio that I would like to utilize the ignition wire TX inhibit option on, but I have not been able to figure out what all needs to be enabled/disabled within the RSS to make this work. Just by simply enabling the ignition wire TX inhibit option under the radio wide screen in the ...

Thanks for all of your help, Bob. I really appreciate it.

OK. Good and bad news. Good news first. I checked ALL of the mini coax cables, and they were all plugged in and seated correctly.

Now the bad news. That means that wasn't the problem, and we (I) still have the problem.

One thing though, when TX on a simplex channel, initially the transmission is ...

When I first got the radio and programmed it, it would receive sporadically. Sometimes it would RX all day, sometimes for just a few minutes, but once I turned it off and then back on, it would start working again.

However, when it DID receive, just before it would quit RXing it would start ...

Well, I determined that the radio is TXing dead center on any given frequency. While it will TX on any given frequency, it will NOT receive anything , anywhere. The receive LED won't even light when I TX to it from only a few feet away. It's almost as if the receiver is dead. Could this be an ...

Alright. I programmed in the control channels as conventional/simplex channels and I heard absolutely nothing on them. I do not however get any error messages on the display (ie: FAIL001). I do still get the 'out of range' indicator though.

Where are these synths located, and does anyone have an ...

I have a C7 800MHz. trunked Spectra that I have programmed, and correctly I might add, but I keep getting the 'out of range' message on the display.

I have already checked all of the personalities and frequencies associated with them, and everything is fine. I also double checked that the antenna ...
