Monday afternoon pass of the ISS with FM communications from the Amateur Radio repeater on the ISS.

Monday afternoon with an overhead pass of the ISS with FM communications from the Amateur Radio repeater (NA1SS) on the International Space Station (ISS). The ISS was at 46° elevation. Because of Doppler shift requiring receivers to adjust by +/- 7 to 10 kHz, I’m tuning the receiver frequency slightly to compensate. (Hams exchange their callsign followed by a 4-character Grid Square that identifies their location on the globe. For example, the Putnam County area is Grid Square EM69.) I’m using an ICOM IC-705 Transceiver and Comet GP-9 Dual-Band VHF/UHF Vertical Antenna at 25’ elevation using the SDR-Control iPhone app. — The International Space Station (ISS) operates a cross-band FM repeater (IORS) that allows licensed amateur radio operators to communicate via a 2-meter uplink and 70-cm downlink, generally using an uplink of 145.990 MHz (PL 67 Hz) and downlink of 437.800 MHz. — #iss #spacestation #amateurradio #hamradio #AMSAT #repeater #space #icom705 #sdrcontrol
