[Elecraft] Bad crystal filter ?

[Joe Subich, W4TV]

Jamie,

What is the offset (FL# FRQ)?

What is the PITCH in the K3S vs. MARK in your RTTY software?

73,

Through the FL3 (1.8 kHz) filter, an RTTY signal would be nice and strong with good S-meter indications. Going to 400 Hz the signal would nearly be lost and I could not decode it. Going to FL5 (250 Hz), the S-meter would pick up again with strong signals.
