VX-920 and others out of band

Post by silverbk » Fri Jan 27, 2006 12:41 pm

I know this topic has been discussed in other threads, but I think we need a central place for the info.

I have several vertex radios and they are great, however I would like to get my 920 to work in the HAM band, eliminating the need for me to carry three radios.

I have a vx-500 and a 520 and they seem to take the HAM freqs (UHF 70cm) without any problem. They do however program with DOS based software.

The 920 software is Windows based and semms to automatically revert to a default frequency every time I enter an out of band freq.

I am wondering how to best attack this, one member here suggested I wait until they ship software with the correct split. I would also like to explore possibly editing the split in the software or editing the actual freq with a hex editor in the personality file and the writing it to the radio.

any thoughts?

Still looking for any info on getting the UHF down to 440 mhz.

Ironically my VHF will do 2 meters right out of the box. My vx-427 will do half of the ham band stopping at 146 mhz.

all the Band Splits are in two Files
Use Hex workshop to load the files and search for the Band Splits in intel unsigned long format then change to what ever you want the High or low band split you want
For VHF the Files are
defaultv.c59
defaultv.c59h

And for UHF there are Two sets of Band Splits
UHF A
defaultua.c59
defaultua.c59h

UHF D
defaultud.c59
defaultud.C59h

Karl,

Do you know the exact string to search for?
I am having trouble finding 450 mhz in intel long unsigned.

your not looking for 450 you need to look for 450000000

OK. it took me a little bit to get this to work.


hex string is 40A5 AE02 needs changed to 0063 9F02

thats to go to 440

Have you tried this on vx-4000 software. Would die to get the 148 limit down to 146 or even 144 mhz.

Thanks Frank, that worked like a charm.

I guess I am going to sell a few ham rigs now.

Hey I got a Vertex 929 in the 400-470. How would I make it go out of band to 470+?

ok I am getting too many e-mails asking me to tell them how to hack the software and when I tell them they Either don't know how to use a Hex Editor, or can not find it because they don't know hexadecimal and don't know what to look for, then they send me the software for me to hack for them. And its not just the VXR-9000 its all kinds of other radios mobile and portables.

So here goes, everyone looking to hack radio software should look at the page ( http://batlabs.com/wincps.html ) on BatLabs web site. And read about hacking radio software Also learn everything you can about using your Hex Editor and all the sub parts of the program.

In some software the band splits are in the the main program ( The .EXE file ) and others are in a sub file. the VXR-9000 band splits are in the file
CE60uhfd.C60
in some software you search for your the offsets in Intel unsigned long format
But in this software and some others you search in Motorola format
so you first use the Base Converter to convert 450000000 to hex 1AD27480 and you look for that in the CE60uhfd.C60 file and you will find 8 offsets where the band split you want to change are located. then use the Base Converter to figure out what you want to change it to and over write the 8 places with the new hex and save the file. if you did everything right you should be able to input Freq's to want you lowered the band split too.

Good luck every one

Some radios i found to make out of band is to edit the default file (if doing new)

Or read the radio and save the data file. Seach for the band limits it should be toward the end.. and modify and viola...

I really hate to bring an old thread to life, but I didn't want to get in trouble for starting a new thread talking about some thing.

I have tried following some of the steps here for the VX-427 software but with no luck. I did the hex editing on both the exe and the default file for the UHF version but how ever if I try to enter a freq below 450.000 it will just reset the freq to 450.000. Has any one had any luck with bring these things out of band?
