[RTTY] Simple filtering for SO2R ?

[Jeff Stai]

Stubs may be sufficient and they are easy and inexpensive to start with.
Buy this book:

And all your questions will be answered, including how to analyze your
situation. Best $15 you will spend.

Note that the relative positions of the antennas are important. If you
don't have to point antennas at other antennas in normal operation that
helps a lot.

Have fun! Jeff wk6i
