Improve Hamlib behavior during TX. (#893)

* Reenable timeouts once connected to the radio.

* 100ms might be a bit better.

* Request current frequency/mode every second (instead of every 5 seconds).

* Remove pre-PTT interrogation of frequency/mode.

* Increase Hamlib timeout to 500ms per user testing.

* Add PR #893 to changelog.

* Update comment.
