I have got a 2m rx front end working, it use Coilcraft coils for L201 and L202 for 2m they are 146-04J08SL.
I would like to build two more, one on 70Mhz(4m) and one on 50Mhz(6m), is there a formula to work out the new
capacitor and coil values marked as a * in the circuit below.
I do have some coils from Coilcraft;
146-06J08SL - 6.5t
146-07J08SL - 7.5t
146-08J08SL - 8.5t
146-10J08SL - 10.5t
