Bugs fixed:

When frequency is set again and rf is off, it was becoming on and display showed off. It is fixed as always looking for isrfonoff variable.
When interrups started, device become bricked. It is fixed by clearing every interrupt when functions started.
Temperature calculations were wrong (fahrenheit). Multiplier was integer. Now it is float and corrected. Bug #1 fixed.

Improvements:

Arduino's analogRead function is very slow for us and it is changed to free running mode and always on. Therefore this gives 2-3 times boost in calculations.
To be able to make faster and accurate modulations, delay calculations are now in nanoseconds. This gives internal modulation frequency precision.
Now external modulations are mocuh faster. They precalculated in 7 bits. So in infinite loop, it only get adc value and use lookup table to find pre calculated value. This made external modulation frequency limit 100 times higher.
RFSA (Step attenuater) was using 5 MHZ SPI clock. It is doubled.
Internal modulation calibrations are corrected.
Now every modulation can be sweeped. It was only availabe in Internal AM and FM.
