Ok, thanks!

I have a couple XPR 2500 radios that turn on, can be read and reprogramed, but I am unable to change frequencies and they will not TX on the channel they are "stuck" on. If I take a control head off of a known good working XPR 2500 and swap it with the problem radio, I can change channels,...

Seth, thank you so much for your help. I have talked to my volunteer contact and he is going to talk with the NOAA person who hopefully has what we need to remove the ASK from the radios so then I hopefully can help them out.

cbroseinak

I do have a contact person with NOAAA that I believe has a key. Is there anyway to just do one and then OTA program the rest? I did look into the way the one radio they provided me was setup in advance system keys and that feature is enabled. Does it take long to unlock each unit if he has to them p...

Local search and rescue volunteer group received a bunch of XTS000 radios donated from NOAA fisheries. I can read them, but cannot program anything into them. I get a pop up window saying: "Cannot write radio with out advanced keys" So what do these radios need to allow them to be programe...

Had a problem Flashing the bios on a CDM1250 and its dead now. Was thinking that I could swap it out with one from a donor board that is not corrupted. Was wondering which IC performs the bios duty on a LDMOS 25watt mainboard.

cbroseinak

Ok, thanks! Maybe I'll give one a shot and see how it fares. I think I have a decent cadaver here I can practice on.

cbroseinak

Honestly unless you're a whiz with a soldering iron and have all the equipment needed to retune you are probably best off going the flat rate route. I'd bet you're looking at about $200 in parts and labor per radio at the local shop, for about $50 more you could send it in for a flat rate and Motor...

cbroseinak

Jack thank you. I read the radio with tuning software and went into the K&M tuning section, selected one of the High pwr boxes and saw only about 1.5watts when it should be 23watts or so according to the box selected. The low pwr box on that particular freq was like .4watts or so. So it is one o...

cbroseinak

Have a couple of CDM1250's with TX power out put in the 1.5watt to 4watt range. Is there a usual suspect that needs replacing when this happens, or is it time to ship it to the depo for a $285 bill? I do have CPS for these and tuner software, but i'm not sure how to set/check PA , battery voltage,ec...

cbroseinak

You are correct Jack the HT1250 wont decode, encode only, and escomm I did find out about the Ht 1550XLS too, so you too are right on with your info. I ended up using an XPR4450 and XPR3500 for testing and it was an easy deal getting it all going, now I'm just working thru the little check box detai...

cbroseinak

Trying to get a CDM1250 to encode MDC to a HT1250 which will receive the MDC signal which will cause HT1250 portable to go into an Alert/Alarm mode. I am assuming this is possible by looking at the programing, but damned if I can get it to work. The need is for a Emergency Medical tech at a mine to ...

cbroseinak

Working with an MTR2000 base stn and was wondering if it is capable of scan? It has about 5 Cpi TR16F tone remotes tied to it. I did not see scan enable in program software anywhere, but maybe I do not have the correct software or add in card to get it to scan.

cbroseinak

Ok, thanks. Performed work as recomended and its doing its thing. Actually doing a bit better with the solder connects than with the rubber carbon pad, getting 13+watts now instead of 10+watts. Calling it "good" till it bites it totally.

cbroseinak

Programed with-in its operating range. The rubber piece with the carbon contacts is now bad...I tried to clean it. But before the cleaning attempt, with the cover off and heavy pressure on it I was only getting a couple of watts, well below the 10watts I was getting. After cleaning I only got about ...

cbroseinak

Have a CDM1250 VHF Hi power that produces about 10watts. When I use service tuning software and check the radio power level settings it produces the correct power levels, but when I back out of the tuning software saving everything, its back to 10watts. Bench supply and cables are fine as any other ...

cbroseinak

Anyone know what has happened to CDM's? did they break a die for some silicon or have to throw-out some poorly made China made peices? I'm being told "sometime in April" for availability.

cbroseinak

I just checked another (4) brand new CDM1250's and on three of them screw#1 was loose by 3turns easily and all other screws were 1/2 to 1turn to get them tight. The fourth one all six screws needed 1/2 to 1 turn to tighten them and I am not cranking these down tight, I really need a small torque wre...

cbroseinak

Ok, so for grins I just checked a new radio and screw #1 was so loose it probably would havce fallen out if I had inverted the radio, the only reason it hadnt gone further was it was hitting the top wrap-around cover.

Cheesh Motorola...

cbroseinak

I plan on using (2)Gr1225 repeaters in bi-directional mode. Do I program them both for Bi-directional mode or just one?

cbroseinak

Wow! This simple fix repaired the problem with this radio and another one another customer brought in and complained about noisey TX. The screws on both these radios were not as loose as some I have seen in the past. in fact I would not realy have considered them "loose" but they obviously...

cbroseinak

First off, I should have clarified that the noise problem is Transmit noise from the radio. Yes, like bad alternator noise sounds being transmited. Receive is fine. Just seems weird that a new radio or having the radio repaired by Motorola fixes it. And the radios are shipped to Motorola with compla...

cbroseinak

I have run into problems with the CDM1250 and CDM750 mobile radios loosing filtering capabilities of vehicle power supply line noise after time. A customer just came in with a CDM750 in vehicle and with engine running sounded horrible, I swapped radio out with a new CDM750 and noise was totally gone...

cbroseinak

What is the proper charger kit number for charging the NTN7372 battery. Will the NTN1667 work?

Thanks!

cbroseinak

I would like to post a WTB. Need to find out if anyone has some old but working Telemobile equipment.

cbroseinak

Will, thank you for the responce. However, i'm going to set it up as a Bi-Directional repeater and set hang time to 0sec. It still works poorly in that config, but I lack certain skills and dont wish to try to correct something that I think M dropped the ball on.

cbroseinak

Have a CDR700 repeater with a pair of CDM750 UHF mobiles, set up as a Uni-directional repeater and It will not TX from a handmic/desk mic while responding to field units while the repeater is in hangtime. Works fine portable to portable, but portable to repeater being used as a base radio is funky. ...

cbroseinak

So I DID NOT have channels 1,2,3,4 and 5 set in the little drop down box's asociated with their respective frequencies in the page where you woulld actually enter the frequencies, tones/no tones,ect area of the CPS. So the special function I wanted slaved, i.e. Low Power and scan on a particuilar ch...

Yes sir, 5 channels in the zone assignment and then one added to personality

cbroseinak

PM1500 VHF conventional using 5 channels only. 4 channels set to high power and the 5th channel with "Low Power" selected for that channel. Low Power is set to 25watts and High Power @105watts in "Radio Wide" section of the programming. I am able to program a control head button ...

cbroseinak

Thanks for the confirmation Jim, actually a new unit out of the box. I will check it with the service monitor to make sure, I was just amazed as to how sensitive it was.

cbroseinak

After programming some PM1500's, the mic gain seems way too hot with std settings. I can hold one hand about 3ft from the mic, snap my finger and clearly hear it over the sevice monitor. These are programed conventenal VHF narrowband freq. In the "Conventional personality" "Advance&qu...

I did have the box checked to strip PL. But the fleet has the monitor button enabled and also off hook monitor which all might have to change.

I am confused as to the CWID "TX interval" and "Mixed mode timer" operation of the MTR3000 conventional programing. I had both enabled on a station. The "TX interval" was set @15min and the "Mixed mode timer" @20min, the customer complained that they were hear...

Ok, I called Motorola tech because I need a tone controller for a project. I'm looking at the L3276 tone remote adaptor. When I mentioned I needed more than 8channels he informed me that I would need the CDM1550-LS+ for channel steering. Is that correct or is he only reading his teleprompter and rea...

Thanks for your input, i'll check the Midian and Zetron out. Any other input about the CPI or Motorola would be helpful as well

cbroseinak

Recommendation for a tone termination panel to control a CDM1250 for 8 frequency selection. System has a C200 and (2) T5600 controllers. Either the CPI TTP216 or Motorola L3276 tone panels. The only out of ordinary issue is that the tone line-up is not standard after F1 and F2, it jumps around abit ...

[quote="Jim202 Some place I believe that there is a service note on this. Bottom line is the red wire from the control head must have a hot +12 volts on it all the time. You can switch the yellow wire to be able to turn the radio on or off. If the red wire is switched with the yellow wire, you ...

Thanks, but my ign sence (yellow wire) is actually un-hooked at this time, and I mistakenly put "XTL1500" its a XTL5000 100watt unit. With control head, ign sence wire and receive only wires un-hooked, and only the big cable going to the batterty, I still get 0.78amp. I called Motorola and...

I got a complaint from Customs about an install I did on one of their vehicles. They complain about battery drain, and when I do "parasite draw" test with the radio hooked-up and NOT powered on, I get 0.78amp current drain. With the radio un-hooked at radio or just by pulling the fuse unde...

So do you plug the MTR3000 AC pwr cord into the SEC2450BRM? or run the MTR3000 with DC as the primary power source using the SEC2450BRM? looked at the website and dont see much info on this.

cbroseinak

Was wondering if there is a better alternative for a revert charger that will work with the MTR3000 than the overpriced Argus L1884 unit. Will be used on a 100watt VHF unit

cbroseinak

The duplexer is a Sinclair Q2220E and 154.250 is the RX freq.

cbroseinak

If you have a duplexer that is tuned for lets say 159.465tx and run freq 159.450tx thru it, how bad will the performane be?
Will duplexers generally tolerrate a +/- freq deviation from their tuned condition?

Because the old revC uses a 100ms pick off an eprom, I've decided to get one of the new revB panels with the jumper for momentary or latch setting option. No doubt someone with a little more smarts could figure out a way to get the thing to work via a mod to the radio, but i'm not going there with t...
