Since you stated even the power up beep is distorted than we know its NOT in the reciever stage and being introduced in the IF stages of the reciever stages . This can cause what you described but the power up beep eliminates this. Probably just a crappy speaker but they usually sound "tinny&qu...

It's probably at the repeater site. It's not Xmitting PL once it no longer receives from the subscriber unit. Once it no longer sees an input carrier it stops Xmitting the PL tone . Very common set up . Reverse burst only is useful in old reed type PL modulators to stop the reed from vibrating. New ...

If you moving it 1Mhz from what its tuned for now ,then w/o doubt it will need to be realigned . If it was Gov't surplus and your wanting to make it Ham then no doubt it will need to be realigned. If the VCO's and preselector (if equipped) are not realigned will make it a boat anchor for $50 . Not l...

You mentiom you have 20 and another guy has a bunch .............Quite a few lets say . ALL of them are low TX power with levels all over the place . The common denominator is the watt meter you are using - you tried another with the same sporadic results . You did not mention the RF cable your usin...

guy being a guy

Oh , yeah another way to troubleshoot that I forgot ........... Go to both ends of the line and REVERSE the copper pairs. Swap the pairs TX and RX. Now you have intermitant RX at the deskset and you can TX fine - BAD PAIR ! Just get them to give you a new circuit and spend your time doing something ...

27 years experience as a Motorola system tech ........... I can tell you now its the phone lines ! It happens (intermitants) during the summer months - heat , copper expanding and contracting over miles and miles of its length. The phone "people" have their own specs of acceptable loss whi...

I just had to change over myself.
I had an I576 and Sprint sold me a Iphone 4S as a "transition" phone for $50. I LOVE my new phone to say the least. I also was happy with the price and service Sprint gave me - no complaints.

" its working on a freq that its not tuned to be working at like it should be " - Kinda a no brainer as to why you have poor coverage.

Would have been nice if maybe that info was given in your opening paragraph.

guy being a guy

Only ideas to chew on ................ Are you guys on this water tower BOTH UHF ? At least in the 400mhz regardless of HAM band and 450 - 470 ? I also never read anywhere what the other guys band was - UHF or VHF, maybe 800 ? I state this as I would not compare a guys coverage at 150Mhz. is going t...

guy being a guy

Yeah , the power up stuff using this set up varies . I don't pay it much mind really. It can get power thru the 16 pin connector sometimes . One radio will have audio the other won't . One speaker is disconnected , the list is long .............. BUT ............... Make sure the large PA connector ...

guy being a guy

Yep, Fail 01/90 are the heads not talking to the radio. I know with Spectras mounted in say an ambulance with a front and rear control heads..............There was indeed a "master" and a "slave" control head. The radio knew which control cable end needed to see which head - mix ...

guy being a guy

Oh yeah ..........We have assumed that the TX and RX jumper cables to the duplexer is correct . 100% sure the RX cable goes to "High" or RX connector on dulexer and to the RX radio ? TX is connected to "Low" or TX side and also going to the TX radio ? These jumper cales are nice,...

guy being a guy

I guess you could even do it maybe a better way.........
Simply turn off the TX radio. This then tests the antenna, RX side of duplexer, and the RX radio !
Plenty of sensitivity and range on JUST the RX side ?

Xmitter is "desensing" the repeaters RX . Tune duplexer correctly and enjoy !

guy being a guy

Take the antenna and connect it directly into the back of the RX radio. Aim your webcam for the red LED on the RX radio and go for a drive. Audio off the cam would be awesome ! Good RX sens ? Antenna and RX radio are OK then . If not, suspect antenna and do a FULL visual inspection . Ohm out the coa...

guy being a guy

First thing that I thought of ....... " the radio will act like it is sending the emergency but nothing happens." I will take this to mean it is indeed keying up when P4 is pressed ? Keys, but no type of modulation ? Make sure you have some type of TX signalling enabled like MDC . Enable M...

guy being a guy

Oh yeah ........ If you suspect something on the RX side ( no antenna issues ) but RX side duplexer or radio ........Thats not very easy to shade tree troubleshoot the RX. Again easier and better with test equipment - sorry :( I did however forget the power supply - you never know. Could have surged...

guy being a guy

We have to find whats "bad" first . Use this repeater as a base station. Go grab a mic and send a portable out in the field . Have him start at the base of the repeater and drive away ....... Won't be long before we find the problem is TX or RX of the "base" station equipment . S...

guy being a guy

I actually think you have about 3 issues ....... Flashing red LED and some odd power up stuff - bad battery. Look at the batteries bar code sticker. There are 3 numbers to the upper left of it. First digit is the year it was made and the other two are the week of that year. I would suspect anything ...

Been a bench, field and drive up Motorola technician for 26 years..........99% of the time the problem in in the vehicle. Start with the antenna and a watt meter to make sure it's good with no reflected power. Usually a beat up mini UHF antenna connector or they found an old 800mhz antenna whip in a...

I myself think it's pretty easy. A pair of pliars. pulling straight up will work. You may distort the rubber on the outside if that bothers you. A small flathead srewdriver and just pop it off. They ( Motorola ) produced a special knob pulling tool and chassis opener. It does help and I use it. Part...

If you have voltage on both sides of the volume pot then the fuse is good.

I bet you have at least 2 hours messing with this remote and changing the radio. One more hour posting on this board. Thats 3 hours of your time and it still has issues............Maybe more.................. I could just have reprogrammed the original Spectra consolette down to 2.5 Khz TX deviation...

MDC is "data" ................it is the information or data burst that tells the console what unit is transmitting. You know those darn irritating " BWWEEEKKKSSS" you hear .........Thats the MDC "data" signal which is essencially the unit ID. The console will take that ...

Don't mean to be "mean"........ How do you expect to repair a receiver without the proper equipment and knowledge ? We are here to provide the knowledge and advice, but it sounds like maybe you need to pay the "radio man" . Not being mean , but when a person asks for advice here ...

guy being a guy

For me the key words I picked up on were..........."appears to be a repeater controller" AND "spectra tac chassis". What this "repeater controller" actually is , is a voter and somewhere should be a compairator (?)........ Spectra Tac and this Micor repeater are OLD ! I...

I believe you may be having this RX audio problem due to line loss of the wire your using . I would not run it down telco or multi strand cable more than 200ft. or so. When we run tone remotes across a city using the old Ma Bell copper telco lines the phone company puts cards on them to "condit...

guy being a guy

By "deaf" I'm thinking you mean no RX ? If the TX side is fine ( ESPECIALLY being on frequency within say 500hz) AND you have no RX .............The 14.4 crystal is NOT the problem ! IF you are WAY off frequency on the TX side here is what you can do.................. First double check yo...

guy being a guy

I always use "flat Rx Audio" so I think your good there. I'm only guessing on this jumper............Maybe it increases the voltage to the audio amp section which in turn increases the overall gain and hence louder audio. If the manual states this configuration is OK then I don't think you...

You did not include the model # so here are the basics but the key is the EXACT model # . HT1250 8 zones 128 channels NO TRUNKING ! HT1250LS only 16 channels conventional , LTR trunking only,no mdc HT1250LS+ 5an model 18 channels conventional ,LTR & PASSPORT trunking ,no mdc 6an model same as ab...

Just an FYI to check on your monitor......
BOTH the generator out AND the RF ANTENNA ports ( BNC connectors ) are fused.
Simply unscrew the BNC and check the little green pico fuses.
They are like 1/16 amp or something very small.

I used to work at Bearcom as a technician............. No BC130 can NOT program a BC120. The BC120 was specifically made for Bearcom and has it's own software for only that radio. It's a darn good radio truth be told. Just an FYI - if narrowbanding it ..........If all is well at 25kc and you change ...

guy being a guy

" Do I seriously need to spell this out so you can even understand? " Obviously Yes. On your original post you called them "tags", so I DID assume and kinda asked in my very first sentence what exactly your reference to "tags" was . I also took it a step forward in my r...

I agree 100% with Astro Spectras answer. What you are attempting is not for the average guy - programming that is. Firmware, software, cables , KVNs , USB ports , comports , Apple or windows, just a TON of variables here ! You mentioned an exsisting system - go to the shop that maintains that system...

guy being a guy

I am assuming you are referring to maybe the manufactors name or model number stickers on the face of the radio. Serial # sticker on the rear chassis ? Why do you immediatly get suspicious - makes no sense . Research the seller is what I do . I have been repairing radios for over 25 years, I don't A...

guy being a guy

The 800 band is NOT required to be "narrowbanded" which is what the term 12.5khz refers to. Rebanding and narrowbanding are different. Read other radios and look...........If dispatch is always telling you to "speak up" then your at 12.5 and everybody else is at 25kHz. I've also ...

guy being a guy

Just throwing it out there.... Are you SURE its actually an MTS series ? Could it possibly ACTUALLY be an HT1000 and a previous technician just threw on a MTS front cover or rear chassis ? Open it and then look at the RF board sticker - google that # and that is ACTUALLY what you have and what the s...

guy being a guy

I bet messing around , pluging in and out of that rear 16 pin connector ,you BENT a pin or two. Straighten them out with a pair hemostats and be careful as I do it all the time.
When you do that it causes the runner to open

guy being a guy

Look at the small white 5 pin connector on the logic board. The red wire is the 12 volt comming in from the main connector on the PA. Should be 12volt. If not,remove PA - I have seen the reverse polarity diode get hot and unsolder itself. Got 12 volts on that red wire ? Make sure then you have it on...

guy being a guy

No .......It will give you a "fail 01/90".
Much like other models the radio "talks" to the control head, when it see's the wrong model than what the harware is programmed for then it does not know how to "talk" to it.

guy being a guy

I honestly think $30 is a pretty good price. Maybe see if the seller will give a better price if you buy in bulk ? Motorola likes to keep a "lock" on the quality of their product so you really won't find ANY aftermarket China or USA made stuff and I personally would not trust it. As far as...

I currently reside in Ft Lauderdale. REALLY love this town and want to stay here, but I am unemployed right now and am looking for ANY kind of work someone may have. I am a single guy and can travel at a moments notice as well. Contract work, overwhelmed by narrowbanding ? got a project where you ju...

I agree with MSSDave. MOST EVERY "license" i have seen and assume we are discussing is an FCC license. If It is I have oly seen "effective radiated power". That being said it can be measured pretty simply. Go to the antenna , disconnect coax and measure the power out. If you need...

guy being a guy

I'm thinking the accesory connector is not programmed correctly. I think it has a "repeater" option or something that will jump right at you when you look in the programming menu. Also make BOTH radios the same in the prgramming of the accesory connector. If TX radio is programmed "re...

guy being a guy

Yes, your correct it will and can store it's incoming audio. The tones and voice.Basicall anything the receiver hears. It would need to be carrier squelch to record the tones though. BUT ........There is no way I know of to automatically activate the transmitter once it has recorded something. It ba...
