CHIRP

What have you observed, and what would you consider proper behavior?

Remember that the D700 cannot store split band channels (only split channels within the same band).

The system appears to reject the channel, where I think discarding the non-compliant split and storing the rest makes the most sense.

What do you mean by "the rest"? Does it stop uploading channels after encountering the split band channel? It should continue copying the remaining list of channels even if one channel is incompatible.

It skips over the entries with splits. I'm proposing that it should enter them into the radio as best it can, i.e. discard the split TX frequency and store the rest of the entry.

Ok, how about this algorithm:

try:
  set_frequency(rx, tx) # split channel
except SplitBandFrequencyError:
  set_frequency(rx) # simplex channel
  raise SplitBandFrequencyError("Could not write tx freq outside rx band")
# continue with other channels

This attempts to write the split you give it, and upon failure will write the receive frequency before reporting an error. It still reports an error just as before, but will program all channel parameters except the tx frequency instead of leaving the channel blank.

That sounds ideal. Thank you!
