[hpsdr] Apollo schematics

[roland etienne]

Hello,

 

Looking at the nice job you're doing with Hermes and Apollo, fine pictures
on the wiki, I do not understand the T/R switch part of Apollo.

 

What is the use of T41, T42 and T43?

 

I am sure Hermes will be a winner in 2010!

 

I have made my third hpsdr-hpsdr qso with G8ALS last week!

 

Season's greetings to all of you!

 

73,

Roland f8chk.
