Problem with MT2000 out of band change

Post by N2YP »

I have modified the mtsx.obd file as suggested. I want to program my MT2000 to receive 485 mhz. I have an MT2000 AN model (403-478)
Using the find command in Hex workshop, I have changed every "470" to 512. When I connect to the RSS, I still get the "Frequency out of range 403-478" error. I'm stuck, any suggestions out there?

MT2000 out-of-band

Hi,

The number you need to change is "478.000", which is the upper limit for a "R" radio. there are a couple "470" numbers in the .odb file, but I'm not sure what they do. If you look at the file, you will see that the band limits come in clusters of high and low limits, with RX and TX in separate places (no, I don't know which is which!) Therefore you will need to change the 478 to something higher in two locations.

If you look that the location address within the file shown in BatLabs, it should be very close to those numbers - other areas of the file will not be what you need.

That said, I've never actually used the "stretched" limits of MTSX except for 900 mHz stuff, so perhaps there are some peculiarities at UHF I don't know about (but I doubt it).

Thanks, I have used the find command in hex workshop and cannot find any more "478s" to change. I'm really stuck.

Hi,

That doesn't tell me much about the radio - what is the whole number?
