Hi Lawrence,
I now have a much better idea of your thinking; thank you.
I suggest you make your detector tunable over a 1 MHz range. That way, the osc. injection can be in 1 MHz steps with front-end tuning to match. By using 500 kHz range, the osc. needs to change at 0.5 MHz intervals - and that makes the design of the oscillator injection rather awkward.
