Description
160 Meters currently available. If you’d like a custom cutoff frequency please contact me.
K9DP QRP Low-Pass Filters are designed to pass signals below the cutoff frequency while effectively blocking signals above it (see chart below). They help reduce interference and suppress harmonic emissions. Compact, lightweight, and built for portable operation, these filters are well suited for POTA, SOTA, Field Day, contesting, and other field use. They have been tested at power levels up to 20 watts with SSB, CW, and digital modes.
