I sent the email to g7jiq but last time I emailed, he said he didn't receive anything

His email address is on QRZ.com, so you could try emailing him directly

Hi G4EML

This is where I have got to so far.

I am using the latest software posted.
I also tried an external mic, (no change)
I tried leaving the programming cable connected, (no change)
All is quiet with the cabe left in, but it still only sends the first two dtmf with the ctcss , the rest are send with no ctcss.

I must have an oddball radio, trust me to buy one with none standard i/c's.

Thankyou for your help,
I will await the test file and see if that makes any differance.

I sent the test file yesterday, your email system must be blocking it
Check your junk mail and antivirus quarantine folders

Hi VK3KYY

I got your file ok, (many thanks)

When I flash the radio it just goes blank, and does nothing when restarted.
I have a cloned CPU, have you sent me a file for the none cloned CPU ?

Reflashing with the latest beta ver returns it back to usable.

The file was sent to me by Colin. Possibly his code did not have the fix for the new CPU.

I don't know what happened there. It worked for me originally but the file I sent no longer works here either. It must have been corrupted somehow.

I have just built it again and I will send it again.

Just to conclude this thread.

After some experimenting, with G7JIQs help, we have found the cause of the problem. It appears that the HRC6000 DMR chip was shifting the transmit frequency by + 10 KHz in between each digit. However this only happened if the Reference oscillator frequency correction in the calibration menu was less than 128. That's why it was not happening on all radios.

This has now been fixed and the fix will be included in future releases.
