Hi Phil,
You should have some idea of when you might want to use diversity reception.
If you do then the filters that would be in use on your main RX should be

Your second antenna does NOT need to be resonant to receive, either by itself
or with another in diversity mode. My receive antenna is seasonal so I have
employed antennas for other bands for receive when it is not up. While a non

Read the manual carefully - it says that the delay is the time for the

Now, having said that, there is nothing wrong with appealing to Wayne

The two batteries inside each holder are easy to take out. The two
