[hpsdr] Quick question on Alex and Antenna Tuners

[Kjell Karlsen]

Hi Jeff.

This is a very interesting question and I think many of us would like to  
have the ATU connected all the time and change antennas via software  
control.

If 2 extra BNC connectors are installed on the LP filters (or external to  
the filters),one connected to T1,( the directional coupler) and the other  
to the 3 relays then the ATU can be connected to the 2 BNC´s. If not used,  
just install a coax jumper instead,

Just an idea.

73, Kjell
