[hpsdr] Automatic Tuner Unit

[Kjell Karlsen]

Hi Aivars.

It is not possible to use any larger parts on the PCB for Apollo. The ATU  
should work up to 30W but not higher.

I have tested Z100 and it works very well with Munin at > 120W. I have it  
built into the same enclosure as the rest of the HPSDR transceiver and the  
control push buttons are on the front. It may be possible to find space  
inside Pandora for this ATU. It is a pity that there is no output pin on  
Penny to activate an ATU when TUNE is pushed. Hermes has this possibility  
when used with Apollo.

73, Kjell
