Hi all

I have built a separate Relay Switch Box for two Mercuries with two 
relays, so as to switch for diversity mode and to separate the RX input 
from the alex when in TX-mode.
The switch box has 50dB isolation up to 30 MHz and about 45 dB at 60 MHz, 
measured with the MiniVNA. At 180 MHz, the isolation is about 28 dB.

Now, I don't get ADC overflow when TXing anymore.
