OpenGD77 "tx contact" in channels not reading.

[ua0lnj]

The inscriptions are not entirely clear. Original OpenGD77 CPS have "RX GROUP LIST" and "CONTACT" (not "tx contact").
In orignal OpenGD77 CPS, if I set "contact" to any, "rx group list" set to "none". And if I set "rx group list" to any, "tx contact" set to "none".
In Qdmr:
OpenGD77 "tx contact" in channels not reading, always reading "NONE".
RX GROUP LIST reading fine.
If "tx contact" in Qdmr equal "contact" in OpenGD77 CPS, then it not reading. And I can set "rx group list" and "tx contact" in Qdmr simultaneously, is it right?

The OpenGD77 somewhat breaks the common notion, what a group list and transmit contact is.

• Standard (you need both):
  • Group list: the group calls you want to receive on a channel.
  • Transmit contact: the default contact (private, group or all) you want to call by default, when pressing PTT. Calling another contact from the group list is possible, by answering a previous call.
• OpenGD77 (you can only have one):
  • Group list (if set): the group calls you want to receive on a channel and also the list of group and private calls, you can choose the default transmit contact from. You cannot specify the default contact.
  • Transmit contact: replaces the group list (for some reason). The one contact to receive and call.
  • Actually, I do not know, what the OpenGD77 does, if both are defined. If I recall it correctly, it ignores the transmit contact setting.

As qdmr is a tool to program many different radios from different manufacturers, I will stick to the standard.

I currently don't have a radio for testing here. Can you write a channel with a TX contact and without a group list to the radio? If you read it back, is the TX contact there?

I wanted to check that, but: when reading from my RD-5R with current master, the offsets in repeater channels are gone again. That was working in between (since fixed with #516) but seems not to work right now? (Values are correct in the device and setting is "Force DMO: no")

tx contact not saving in radio, always read as NONE.
In all channels with rx group list NONE writing first group from group list:

1. read codeplug, rx group list is a NONE.
2. do nothing, write codeplug.
3. read codeplug again, in all channels where there was NONE, the first group from the list of groups became.

[hmatuschek]

Oh, boy. Why must the OpenGD77 codeplug be so convoluted. Actually, the codeplugs are quiet simple (see https://dmr-tools.github.io/codeplugs/), but there is are a tone of unnecessary side effects. I may need some time to figure that one out.

[hmatuschek]

Some updates: I actually forgot to implement the en-/decoding of the TX contact. It is now implemented in this branch. However, I cannot test it right now, as I am still traveling.

As OpenGD77 does not allow for a group list and TX contact at the same time, I prioritize the group list. That is, if both are configured in qdmr, only the group list will be written.

BTW, this is likely the last issue, that needs to be resolved, before the 0.12.1 release.

Works fine!
Nothing else for now :)
