Review Summary For : KD2C SDR Products HPF-1 High Pass filter
Reviews: 1MSRP: $40
Description:
The HPF-1 is a high pass filter designed to reduce the RF signal levels below 3 MHz. The HPF-1 is effective in reducing or eliminating interference caused from nearby AM broadcast transmitters. The HPF-1 will strongly attenuate signals below the 80 meter amateur band. The HPF-1 comes with a bypass switch which allows you to bypass the filter at any time. The SMA connectors are conveniently located on the rear of the unit, this allows you to save space and avoid clutter on your desktop.

HPF-1 blocked a 25,000 KW AM Radio Station just blocks away! Time Owned: more than 12 months.
My ICOM was DEAD without Dave’s filter. The noise level was over S9! After taking down and then relocating my Windom several times, the same issue persisted. Later that day and completely frustrated, I began to rotate the dial on several bands and faintly heard what seemed like Mexican music. Then franticly searched the internet and realized it was from a local AM radio station's antennas just 10 blocks away from my house pushing out 25 Kilo Watts. I called my Elmer brother, KC2LSD, and he suggested that I speak with Dave Calo from https://kd2c.com/filters. Dave recommended that I buy an HPF-1 High Pass filter for only 40 dollars each. Since I have two radio shacks, one in the US and the other one in Colombia, I bought 2 of them and never looked back. Dave’s High Pass filters are made with good old-fashioned American quality, pride and of course outstanding service. I stand by his product 100 % and I guarantee that you will NEVER be disappointed.
