Alternative oscillator for Corsair and Commando.

One disadvantage of the original oscillator circuit was the lack of available frequency shift.
The circuit below addresses that problem for the versions that run between 5 and 7 MHz.
Depending on crystal used you may find a tunable range of 7 KHz.
Just replace the first 2 stages from the normal circuit with those below.
To use on other bands the windings on L1/L2 would need changing.

Please, can you tell me the value of the 4T-FB inductance L3, thank you very much.
