Glad you got it going. I have two Nuc transmitters with the newer exciters. These will program right in the 927 part of the band. Modulation mods have not been done but is very easy. I have one complete and ready to go on the air. I installed a 800 meg Maxtrac as the receiver and a nhrc controller. ...

walt10

I also want to thank you for a great write-up. I have one behind me that I just installed the 5pin 800 meg for the modulator. Pluged in the mic and it transmitts. I also installed a receiver to make an all in one repeter. The tx audio is great. This unit came with an internal receiver which I remove...

I have heard that later version firmware would allow over 16 channel scan??? Anyone heard this?
Walt

Hi.
I have several CDM-1250s and would like to get them to scan more than 16 channels. Seems that each scan list will only hold 16, even though I can program more than 16 in a zone. Will it scan more than 16 at a time?
Thanks Walt

walt10

I wish it would. I have not found a way except using an aftermarket encoder.
Walt

walt10

You are not going to get the GTX to work on anything but the 25 mhz split. Tx on 902 and receive on 927. I have programed several and they work there just fine. They do not receive very well below 927.
Walt

Never tried that far out. I had no reason to. Only interested in low 450 and 440 to 449.

I have a CDM1250 UHF on my work bench that I use for company Plus several Ham repeaters. The software did not seem to care about out of band.

Are you refering to a CDM1250?

Hi:
Anyone here ever used a Motorola R2002A? I found one and the price seems ok but it has a bug or two. For the most part it is working ok. It does not come with a manual. That will make it a little harder to get going.
Am I waisting my time fixing this thing?
Walt

walt10

I am using MDC1200 with two Maxtracs. My wife does not like to listen to the chatter on the repeaters, so she turns down the radio. Might as well turn it off. SO I set her radio up to only unsquelch when It receives the MDC signal from my radio. When she picks up the mike it puts the radio in Monito...

I have been using the 900 MHz Preamp from Down East Microwave. It is a kit and comes with everything, Even the case and N connectors for $50..
It has been working just fine .

Well Nate... I brought it into the shop. I tacked 12v to the power swithch and went at it with the freeze spray. I found C6 on the HLN 4907 (cpu) Board would open when it was cold. I replaced it and now I can not make it fail again. When I get home I will look up what C6 does in the circuit. Thanks ...

Hello x9000 operators.
I have one that does not like to wake up when it is cold (40 deg F or lower) After the truck warms up a bit it will say system check but still wont wake up. A bit warmer and it wakes up and works fine. Seems to be something with the cpu????
Thanks Walt

Hi Rapidcharger.. I added a schematic of how I wired my IRLP with two Maxtracs. You can use one if you set the jumper on the IRLP borad. Check it out on my web page below.

walt10

Hi: I am using A pair of Maxtracs (for Duplex) to link my IRLP node to the Downtown 900 MHz repeater. Just need to cut the power back some and run a fan on the Transmitter radio. The 16 pin connector will give all the signals you need for the IRLP board. Good luck Walt, WB4LDS Tucson's 900 Repeaters...

walt10

It is very near 100 mW. Just out of the Can on the RF Board of the Maxtrac. That is what I am using to drive a GE 75 Watt amp. And it calls for 100mW.
Walt

walt10

I have done two so far. Blanked the board to get all the acc. Replaced the filters. I removed the PA and mounted a BNC connector on the back of the frame. I checked and got 12db at .15 Microvolts. 20 db at .24 microvolts. They are 5 kc recievers but seem to receive the NB signals just fine.

Walt

walt10

I ran into this a while back. I found a point that I could get 9v tx. I used this and a 50 K pot to feed the op amp. I cut the trace from the two 56k chip resistors. This alows you to set the power and I will not drop back.. BUT!!! Do not set to full output and try to ragchew with it. You will until...

Hi.
Is there a unit that can be used with a repeater controller to limit access by MDC?
Thanks Walt

walt10

Silly question, But you do know that you use the arrow keys to change the conventional channels?
Walt

walt10

Hi Group.. Does anyone know if the 900 Visar can do conventional or is it just a trunking radio.
Thanks Walt

walt10

As for MDC over repeaters I don't really see the point since no ham gear supports it (and not many hams have commercial gear), but as far as I am concerned, ham *IS* all about experimenting and enjoying the hobby so if some folks wanna play with it, have fun! I have two 900 MHz repeaters on the air ...

All it covered was the ash tray and cig lighter,but I don't smoke. I am adding a dual cig lighter on the side of the console so I can charge my cell phone. The cup holder is higher on the dash. (scarry) I don't like to use it.
Walt

The model number is ONE..
I made this myself. It started off just a square frame of rack rail. I then cut the side pieces and bolted it together. It does not wiggle. I have a RIG-RUNNER that I have all the gear plugged into. Keeps things neat.
Walt

walt10

Not sure why????? Both work for me.

Then it seems that the vco will not lock up. I know that I have never seen one not lock up in the 902 and 927 part of the band. I have never tried them at 909. A good reason to change to 25MHz split!!!!!
Walt

walt10

I take it that the radio will take the tx freq. but just not tx there???
Walt

walt10

HI:
I looks like the VCO is not locking up at 909. Did the radio work when you got it?

If your MLM board is later that V5.xxx you should be able to stuff a 128 channel code plug into it. I have done this on a few.

I see how it works now. I think that I can make a relay device that will do the switching for me. I am not looking for ear shattering level just to be able to hear the radio outside. I should have this working by the weekend thanks to you.

HI:
I have a D37 spectra that will do A/B external speaker. I have a horn that I would like to put under the hood. Where do I hook up the second speaker. Is it on the 15 pin connector?

Thanks Walt

My first Motorola radio was a HT-200 crystaled on the 146.82 repeater. Worked great but was hard to bend over if I put it in my back pocket!!
Walt

walt10

Hi:
It seems that It would be easier to change the repeater to 927. Then just about any of the comercial gear will work!
Walt

walt10

Encode only would be just fine. My wife does not like to listen to the chatter on the repeater. So I use MDC to call her.

thanks Walt

walt10

I just got a B5 9000. This one programmed fine except for MDC. Has anyone figured how to make the MDC work?

Hi Monty.. I would sure like to have a copy of the procedure..
Thanks Walt

Hi.. I have a DK and it only had one ch of conventional. I found that its MLM version was 1.6 Very old. It could not be upgraded. If yours is under a 5.1 there is not much of a chance to get it to upgrade. 5.1 is the oldest that I have upgraded.

I will be there. I plan to go Friday evening and bring the RV to camp there. I hate that 3AM drive from Tucson.

Hi:
I have one GTX mobile radio with mic and mout left. I can program it to repeaters in your area. This is a 25 MHz split radio only. It will not receive very well below 927. If you have Spectra and do not want to convert it lets trade.

I got one off ebay that had that problem. After a lot of checking I found that there was a little corrosion on the mic jack connectors. After a lot of cleaning I got the radio to read.
