ATU Tuner button

Hi Irad, Would it be possible to add a optional PTT delay after a frequency change ? As although CI-V works great with inbuilt radio tuner. I have different issue. I use a Ciro Mazzoni Baby loop the Loop tuner receives frequency data via CI-V from the radio and it then initiates a tuning cycle if the frequency has changed beyond the very tight bandwidth of the magnetic loop. This process invariably takes 3-4 seconds. if transmit is initiated during this cycle it can cause damage to the very expensive Loop tuner and potentially the radio. Since the great idea of slots this has become a issue unless I manually operate noting the slot number qsy and then tx once tuning has completed.

Here is how it is done in IC-7300. change marked in RED

The VarAC CAT file is wide open for changes and enhancements.

If you know your ATU command (not all rigs have it) you can add it to your SetFreqVfoA_Cmd command in the cat command file. there are explenations about how to concat command together under the SetFreqVfoA_Cmd command (like settings filters, nothces etc). From that moment - every time you will switch frequenct, VarAC will auto-tune.
