Questions if you don't mind:

1.  What is your wattage at the wall for 231.25M (please include other relevant data such as ambient room temp and PSU efficiency).
2.  What are the rest of the parameters (i.e. 'freq_value' and 'timeout') for 231.25M?
3.  How does one come up with the appropriate 'freq_value' and 'timeout' for a particular frequency?  Is there a certain formula/equation involved or is it pretty much a trial and error method?

Pardon my ignorance in this matter.
