* Select the properly tx harmonic filters

|

* This is valid for the ubitx v4 board; different boards have different TX filter

* configurations and thus will need a different filter mapping routine here!
|

*
|

* The four harmonic filters use only three relays

* the four LPFs cover 30-21 Mhz, 18 - 14 Mhz, 7-10 MHz and 3.5 to 5 Mhz

* Briefly, it works like this,
