Was using my desktop \"mic-in\" jack. Soundcard is a built in on my Dell Optiplex 755. Very limited functionality with driver provided, i.e., poor mic input level control and (my) concerns that sub-audible frequencies lost.\n\nSo, switched to a cheap USB soundcard (Begringer UCA202) which happened to be on-hand. Claimed OK down to 10 Hz. Not fancy, but can input control level.\n\nTADA! Works!\n\n73 es tks agn,\n\nBob\n\n---------------\n\nFrom: KO6TZ Bob<[email protected]>\nTo:[email protected]\nSubject: Re: [amsat-bb] Decoding AO-85 from IC-910H 9600 data socket -\n\tany success anyone?\nMessage-ID:<[email protected]>\nContent-Type: text/plain; charset=utf-8; format=flowed\n\nBob,\n\n\nSo far I have uploaded 276 frames of telemetry using the 9600 port of\nthe sub-band on my IC910h. This is wired directly to the \"Line-In\" of\nmy desk top computer.\n\n I would not recommend using the \"Mic-In\" jack, or a laptop computer.\nThe 9600 port is used because it offers less filtering of the 0-200 Hz\nof the audio band pass. This is the portion that is filtered heavily to\nmake PL tones sub audible in the radio , as well as remove 60 Hz and its\n3rd at 180 Hz from the microphone input.\n\n\nBOB KO6TZ\n\n\n\nOn 10/10/2015 10:30, Bob Mattaliano wrote:\n> Hi,\n>\n> Congrats to the AO-85 team!\n>\n> Trying to decode telemetry using the 9600 output of the sub data \n> (while radio is in Sat mode) from my IC-910H.
