Re: [IRCA] "Frequent Flyer" FSL Project Clears the Turbulence

I think Iâve got around 10 of these in my projects cabinet - one can never have too many variable capacitors with vernier drives.

A sizable order has been placed for these critical components, ensuring that these airport-friendly miniature FSL's can continue to be constructed well into the future.

Craig Barnes, Pete Taylor and I are all eagerly awaiting our next "Frequent Flyer" trip, after having experienced thrilling TP and DU-DX in multiple trips to places like Hawaii and the Cook Islands. The option of having serious DXing gain in exotic places around the world (especially where large external antennas are forbidden) can be a game changer in hobby satisfaction.
