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

* Briefly, it works like this,

* - When KT1 is OFF, the 'off' position routes the PA output through the 30 MHz LPF
|
||||
* - When KT1 is ON, it routes the PA output to KT2. Which is why you will see that
|

* the KT1 is on for the three other cases.
|

* - When the KT1 is ON and KT2 is off, the off position of KT2 routes the PA output
|
||||
* to 18 MHz LPF (That also works for 14 Mhz)
|
||||
* - When KT1 is On, KT2 is On, it routes the PA output to KT3
|
||||
* - KT3, when switched on selects the 7-10 Mhz filter
|
||||
* - KT3 when switched off selects the 3.5-5 Mhz filter
