Hi, I am planning on putting in the voice downlink and uplink for the International Space Station into my Baofeng. The downlink is in the 7Cm band and the uplink is in the 2 M band. Typically in Chirp I enter a normal offset, plus or minus. How do I do this in Chirp to cover such a difference in frequency? . Downlink 437.800MHz FM; Doppler +-10KHz . Uplink 145.990MHz FM with 67.0 Hz PL

Thanks.

Glenn
