DTMF - GD-77S

Post by F6CYK » Wed Nov 18, 2020 12:42 am

Hello to all. I am using a GD-77, an RD-5R and two GD-77S equipped with the OpenGD77 firmware as well as the CPS Community editor version R2020.11.08.02. Thanks to VK3KYY and to the whole team for the fabulous job.
Just one question regarding the GD-77S: is it possible to transmit a DTMF tone (for use of an EchoLink relay or similar, for example,) and if so, what to do and how to program it on?
Thank you in advance for your help.

Hello David and thank you for your answer. The advantage of the GD-77S compared to the GD-77 is to be able to be used "blind" in mobile, by manipulating only two buttons: the audio volume and the channel selector.
I have no difficulty programming one channel per DTMF code for a single frequency used. On the contrary, I see a clear advantage over GD-77 in this type of use.
The problem is that I don't know how to program the procedure for sending the DTMF code per channel, from the CPS editor of the OpenGD77.
Thanks again

Hi,

As I replied to you on Twitter this morning Tony, the DTMF contact support will be available on the next development version of the firmware.
You cannot set a DTMF contact per channel, it works like a contact list, so you need to browse this list and select the desired contact, then trigger the transmission.


Cheers.
