[Elecraft] Fwd: Establishing A New Station

[Walter Underwood]

Actually, tune for resonance, not 1:1 SWR. Loops tend to be 50 Ω, but that isn’t the right measurement. Luckily, tuning for maximum noise is the same as tuning for resonance.

This means, bypass any ATU and tune the loop [only] for 1:1 SWR. Using the "get it close and let the ATU match it" scheme will lead to a round, fairly pricey dummy load.
