Hi Marco, do you have one of these?

If you follow the process of get a serial dump of the upload/download I can review it (post it here), this has a big chance of being just another QYT KT-8900 clone..

Hi Pavel, yes i do have one and you are right, i should have posted it before. Anyways here it comes:

When you first open the program (UV4BAND_E_CPS) the radio reboot itself (the log is 'Reboot Log')
You can edit the memories (mem read / mem write logs)

And you can edit the options (option read / option write logs)

The program is the same for the 8900D and the 7900D.
Hope this can help you and let me know if you need something else!!

73's !!

Try this as a proof of concept. Try to download from the radio. If successful, save and attach the image to this issue. Then try and upload. Do nothing else.

To try this, enable 'Enable Developer Functions' in the Help menu and then use Load Module in the File menu.

So,
i first had to edit the file (nothing serious. On line 500 was missing the 'D')

It reads correctly:

It writes correctly:

But you can't insert any frequency due to 'out of supported range':

Besides that, works flawlessly. Good job !!

p.s dunno if you need it but i'm attaching the img file.

Updated by Jim Unroeabout 4 years ago

This was proof of concept to validate downloading and uploading. I don't have access to a KT-7900D or KT-8900D. I don't have a manual for either radio and currently know nothing about them radio (band limits, power levels, etc). So did absolutely nothing to support the settings of these radios. That is why I said to test downloading and uploading and 'do nothing else'.

Yes. The img file from a successful download will be very useful.

Marco,

Was this image from a KT-7900D quad band? Which radio do you have (or do you have both)?
