I think the fact that now the driver returns an integer as signal strength
instead of a boolean as it used to, would be helpful in your case. So, you
can take the midpoints of the range where a signal is detected as a starting 
point,  and then you can do a local search around each midpoint for the 
frequency that maximizes

/sys/class/pvrusb2/sn-*/ctl_signal_present/cur_val

This will probably work for the fine tuning.

Just my 2c,
