Hi Mary & All, 

I have had some issues with preamp degrade on 432 from 1296 ( not burnout) and I have gotten around it by careful use of HP, LP and BP filters. On some higher bands the WIFI noise necessitates the BPF. On 10 G I have to switch the WG switch when ever the 24 G 100W TX comes on ( dual band WG feed). 

The simple way is to key all antenna relays when you TX on any band , unless of course you have enough proven isolation to not require doing anything 

Looking forward to hearing your big signals up here
