Do you have a HT600E? Well, it sounds like that may be the European model of the MT1000, and, chances are pretty good that you will need the MT1000 RSS in order to program the radio.
All of these radios are built on the same platform, that is why they are covered here.
The HT600, MT1000, MTX800, MTX Classic, MTX900 and P210 all have the same accessory connector pinout, if you look at the programming cable you will see the pinout listed.
Here are some useful part numbers which can be used to make a programming cable, along with some pieces from a speaker mic cable, for any of these series of radio:
If you have an MT1000 and wear it on your belt, you can "flip" the display orientation so that it reads correctly when you are looking down at it on your belt. All you have to do is press and hold the two channel buttons for a couple of seconds. Do the same again and it will flip back.
Out of Band Programming
Programming frequencies outside of the normal bandsplit in these radio's is quite easy. All you need is a saved file and a Hex editor like Hex Workshop.
Enter a frequency you will recognize in RSS into the location you want to change. Save the file and load the saved file from your radio into the hex editor. Locate the frequency you want to change (its in plain ASCII) and replace it with the frequency you want (make sure you edit the ASCII portion) and save the file. Load the file in RSS and program it into the radio.
NOTE: Do not view the channel you hacked while in RSS. This will cause the program to automatically correct the out of band frequency to something inside the band limits. If you do view the hacked channel(s), all the other changes you made will have to be done over again, because you will have to reload the file from disk or re-read the radio if you want your frequencies to be there when you program the radio. So don't look at the channel(s) you changes, you won't see anything useful.
If you do want to confirm the out of band channels in the radio, there is a way. Read the codeplug into the RSS and then go back to the Main Menu. Then, hit F5 for Print/Display, and F3 to view the Abbrev list. You will be presented with a list of frequencies among other settings.
If your radio emits a continuous tone when you go to your new out of band channel, your radio is telling you that you've gone too far. The tone indicates that the VCO has become unlocked and will not operate at that frequency.
If you need the pinout of the programming cable, you can either look at the schematic for the service cable or just the simple connections.
2 to 6 Channel Conversion
In order to convert the HT600 from 2 to 6 channels, you will need to find a program commonly called 2to6.exe. Using this program with your RIB and programming cable, it will do the software modification in the radio to make it 6 channels.
Alternatively, you can use TK (ToolKit) version 1.6 to do the same thing.
With the software conversion done, you just need to clip the channel selector stop under the knob and you are in business. Alternatively, instead of clipping the limiter, lift up the escutcheon and you will find the channel limiter can be moved to various places. Simply unstick it from the escutcheon and place it in the 6 channel place.
NOTE: We don't have a source for TK or 2to6, so don't bother asking.
MT1000 MVA Pinouts
The MVA 25 pin is as follows:
Pin Use 1 N/C 2 Ground 3 Ground 4 DATA 5 PA Squelch 6 N/C 7 External Spkr 8 External Spkr ground 9 Pac RT out switched 10 N/C 11 A+ 12 N/C 13 N/C 14 Mic 15 PTT 16 16.5v 17 Busy 18 N/C 19 N/C 20 PA Audio common 21 PA Audio 22 N/C 23 Ign Switch 24 A+ 25 N/C POWER | Pin 1---Ground | Pin 2---N/C | Pin 3---Ign | Pin 4---12+ (Battery)
There are 2 switches on the back of the unit. One is to toggle between the radio speaker and an external 12W speaker (UP-Radio Speaker, DOWN-12w External Speaker). The other switch is to automatically flip the display (on a 99 channel radio) when the radio is inserted, so you can read the channel right side up (only works if MVA FLIP is enabled in RSS).
FYI, you can manually flip the display on a 99 channel radio by holding the channel up and down buttons for about 2 seconds (if manual display flip is enabled in RSS).
Scanlist Programming for the MT1000
This is a procedure for manual SCAN list programming at MT1000. As you know, a 16ch model of MT1000 can scan 8 ch. These 8ch can be programmed with RSS software.
In MT1000 RSS you must set: USER SCAN PROGRAM to ENABLED.
There is two buttons at the left side of MT1000. Upper opens squelch. We will use lower for manual scan list programming.
1. Turn on the radio 2. Press lower button and turn switch at a top of radio in to scan mode (continous BEEP tone) 3. Release lower button (BEEP tone will stop), 4. Set channel knob to a channel you want to add to scan list 5. Press a PTT button (single short BEEP) 6. Set another channel to add to scan list with channel knob 7. Press a PTT button (single short BEEP), You can set maximum 8Ch for scaning. 8. When you finish with adding channels just turn switch at a top of radio to middle position (single long BEEP).
Next time when you turn the switch at a top of radio into SCAN position radio will scan new programmed channels.
NOTE: The previous scan list is erased every time program mode is entered. An entire list is needed each time.
The procedure for a 99 channel radio is similar in that you enter prog mode the same way, but when you get there you start pushing the lower button again and it will step through 8 entry slots.
If there is nothing in the slot it will show 00, if there is a channel, the number will be displayed. This will cycle around every 8 button pushes.
If you want to enter a channel, you find a blank, (00), and then use the channel buttons by the display to select the channel you want to add.
Then you push the PTT to enter the channel in the list. If you push PTT again, it will erase and go back to 00.
When you have put the channel in, use the lower side button to find another 00 to add a channel to, or a channel to delete back to 00.
Returning the toggle out of the "Z" (scan position) will, like the rotary version, take you out of prog mode.
NOTE: The 99 channel does not erase its scan list when program mode is entered. The mode switch is used review the scan list. The green LED is used to show if that channel is in the scan list.
Converting an MT1000 from 8 to 16 Channels
In order to convert the radio from 8 to 16 channels,
do the following:
P.S. Remember to clip the stop on the channel knob
to allow access to the rest of the channels.
An alternative method that is supposed to work is:
Program the 16 channels into RSS and dump them into the radio. Clip the knob and you should be done.
Yet another method that is supposed to work is:
Change the nineth digit of your radio's model number (ie. from an 8 to a 0) and program the codeplug in. When you read it back out you should have a 16 channel radio.
Changing the MT1000 Serial Number
With unmodified RSS, ths only normal access to the S/N field is if it's empty. If you load a codeplug file from another radio, chances are it'll write in that radio's serial number! That's not so bad if you could easily change it. With these steps, you hopefully can.
Use P200LB software; use this LOW BAND version of Radius RSS, even if you have another band of MT1000.
Read-in your MT1000 codeplug.
Enter the "Modify ID" (F9) selection, you will be prompted to "correct the invalid serial number".
Enter 126aaa####, or any valid P200 S/N prefix, and (F8) from the current menu, program it in.
It should indicate that it programmed it in OK.
Exit the software.
(Haven't tried to enter or modify any thing else while in this P200LB RSS.)
Now follow the previous steps with the MT1000 software.
It should indicate "Correct invalid serial number" in it's "Modify ID" (F9) field.
Change the 126aaa#### to your respective bandsplit S/N prefix. (546(L), 751(H) or 749(U) if I remember correctly.)
It should successfully program the S/N change with (F8).
Determining a MT1000's Bandsplit
Unfortunately, there are only two ways to determine the bandsplit of your MT1000. You either have to read the radio with RSS and look at it, or you have to open the radio up and read the bandsplit from the RF board (it is printed close to the lower controller connector).
The part number for the UHF RF boards are: NUE6911 for 403-433 and NUE6912 for 438-470.
Again, there are only two ways to determine the bandsplit in the radio. You can read the radio with the RSS, or open the radio and look at the split printed on the VCO board.
The available bandsplits for these radios is as follows:
If you are programming these radios out of band, be advised that you will be lucky to get +/-2or3MHz outside the rated split. Outside of that performance first rolls off (these are not wide band radios after all) and then the VCO will unlock (killing the radio or emitting a loud error tone until you reset the codeplug).
Take a look at the Cloning cable pinout.
(The content of radio A is to be duplicated into radio B)
1. Turn off radio A and turn on radio B.
2. Connect the cloning cable (NKN6376A) to the Universal Connector of both radio A and radio B.
3. Place the PL switch on radio A to the carrier squelch position for full cloning, or the PL position for partial cloning. Full cloning will duplicate the content of radio A to radio B, except for the deviation and squelch settings. Partial cloning is recommended due to deviation variations from radio to radio. (Later version MT1000's (B model for 6, 16, and 99 channel portables; A model for 8 channel) have partial cloning.)
4. Simultaneously depress the PTT and Monitor button on radio A and hold.
5. Turn on radio A. The green LED turns off. Release the PTT and the Monitor button on radio A (HT600's and older MT1000's (A model for 16 and 99 channel portables) beep when cloning is complete). Turn radios "off and on" to reset.
6. Cloning is complete once the green LED turns off. Release both the PTT and Monitor button on radio A. Turn radio A off and on to reset.
For MDC front covers (NTN5456, NTN5457, NTN5458, NTN5459, and NTN6009B), make sure that radio B is turned on before it is connected to the cloning cable.
All VHF wideband radios (146-174MHz) are "C" model radios. A "C" model radio can be cloned only to/from another "C" model radio. An attempt to clone a "C" model radio to an "A" or "B" model radio will result in an unsuccessful cloning attempt.
Any unsuccessful cloning attempt (depending on operating condition of the radio) will result in one of the following alerts:
1. in receive (rotary radio) - 1600Hz continuous alert tone
2. in receive (display radios) - 88 displayed on LCD
3. in transmit - 1600Hz beeping alert tone
Clearing a MT1000 (or HT600) with an Invalid Codeplug
Here is something to try if you somehow get the wrong bandsplit programmed into the radio.
When the codeplug has invalid data, it may send out a continuous tone, from the VCO module being out of lock. To defeat this, you can try a couple of things:
- First, open the radio.
- As you look into the front of the radio with the cover removed, there are 2 white plugs near the bottom of the radio. You may have to remove the RF shield to see it, depending on which model you have.
- Now, you can try the quick and simple method of just unplugging both plugs going to the VCO module.
- The other thing you can do is to just ground the LOCK DETECT line.
- The left plug is the one you want. The pin closest to the right plug is the LOCK DETECT line. If you ground it with a jumper, the radio will lock and you should be able to program it. Be careful not to ground any other pins, it can be fatal to the radio.
Once you do this, attach the programming cable, power it up and program as normal.
Power unit down, re-connect cables and it should be back to normal.
Something else to try if you have a bad codeplug in your MT1000:
Make sure you are using a slow computer! This RSS was not meant to run on a fast machine
Try programming the radio a few times and monitor the percentage complete on the top of the screen
If the percentage is increasing, keep retrying until you hit 100%.
If the percentage doesn't change, give up for now, or try the method below.
Clearing a MT1000 with an Invalid Codeplug, Method 2
For a VHF model, change the band split to a UHF, program radio. It will take the codeplug but will not work.
Change the bandsplit back to VHF and reprogram. This will return the radio to all default values.
For a UHF, it is the same, just vice-a-versa.
Clearing a MT1000 (or HT600) with an Invalid Codeplug, Method 3
So, you have a radio that appears DEAD, no lights, no sound, nothing... would not write, sometimes read...
Well, then here is something to try. Open the radio, unplug the controller, and the other plug, playing with whichever would let the radio read/write by a plug/try, unplug/try method. We have heard of several radios being successfully revived in this manner.
