need help converting a VHF Astro Spectra from W4 to W7

[gary123]

I am trying to convert a w4 astro spectra from a w4 head to a w7 head. Has anyone done this before? I have all the hardware and everything looks good. What i need to do is edit the codeplug or replace it with a W7 version.

Here is some info about the radio, the flash is 5D9508-14DE00-4 model D04KKH9PW7AN. The radio is VHF 136-162 ( i can work arround the band limits so any split is ok).

I need to match the above flash as close as possible. I have all the software needed. If someone has a srecord, codeplug or the steps needed to change the head info i would apreciate the assistance.

IIRC, you have to change the S record.

I suspected as much all I need to do is get a srecord I can use. I have one for a W7 now but cant seem to save it as a .cpg archive (so I can see the features etc before loading it to the radio).

I was looking at bitbanging the W4 codeplug I have, if I can locate the byte for the control head.

the other option is to simply force a W7 codeplug into the radio and take my chances. Anyone got a W7 vhf codeplug they are willing to share?

No, there is no editing

Don't try to edit it or do anything. Think of it as a Norton Ghost image of a computer hard drive. Yes, there is a way to edit them but it requires manual manipulation and checksum correction of blocks and lines but that is not done in any RSS and is done in a hex editor. Just load the file into MTSX lab using the S record menu and write using read write with pack no unpack option.

The codeplug thing is confusing you. Forget about that. It's a different format. It's the file read from the radio and formatted by CPS to a human usable format. The S record is the raw machine line code that the radio needs to interface with the firmware. It's everything...tuning and all. It's the entire memory contents.

Forget the whole batlabs old school codeplug forced thing. That only worked in ancient RSS with ancient files. An S record is a memory "snapshot" a forensic read if you will...of the memory structure. You can S record image any legacy Astro and force it into any other legacy Astro but it has to be done as a single record using the pack/no unpack menu. Don't try to look at it.
