TJ6A MOD  - Freq extend

In reacilty, the softare covering 2.5 - 4, 4 - 8, 9.05 - 15, 15 - 22 is in the MCU.
Simply short-circuit 2 pins and you get this interface. Just one touch will do.
If you want to return to the original interface, short-circuit the 2 pins with GND again.




This will make the freq as following:

Band 1 :  2.500000 - 3.999990
Band 2 :  4.000000 - 8.899990
Band 3:   9.050000 - 14.999990
Band 4:  15.000000 - 21.999990

In this new interface, you still have 8 memories.
The memories in the other interface are not affected.
When you return to the original interface, the stored frequencies are still there.
