Needs Assessment
Top goals
Have 2 Geminis (4 LR221s) on the board for Xrossband. Make it compatible with the RX board.
...
I probably don’t need the ESP 01F because Xcrossband has dual band anyway. But there is a chance I will keep it.
...
Need to have high output power, eg 1W. Need to determine appropriate power arch and if the current LR221s are good enough.
consider dual passband filter of somekind

If this can somehow be implemented, it would be a lot more cheap than a tunable filter (which I would never add because they’re so niche and expensive)
