[hpsdr] multiple Alex sets

[Joe Martin K5SO]

Bruce,

I ordered a complete Tx/Rx set for each Mercury, as I wanted both a  
high pass filter and a low pass filter to combine to make a band pass  
filter for each Mercury.  Also, it's handy, as you note, to use a  
complete Tx/Rx set when using multiple Mercury boards because the Tx  
filter board has an integral T/R switch on it and thus eliminates the  
need to handle T/R switching separately.

Further, having multiple Tx boards keeps the option open to utilize  
multiple, phased transmitter boards some day, if I wish.
