    "content": "The #1 thing I've noticed is how much more important it is to tune for\nDoppler shift than when the ISS was using the Kenwood radio.\n\nI've done several tests decoding packets using my Kenwood TM-D700 which has\n5 kHz tuning steps common on most 2m FM radios and then compared results to\nmy Yaesu FT-857D which has much finer incremental tuning.\n\nIn the past, I could decode most of a pass simply staying on 145.825 MHz.\nNowadays, I start decoding around 145.828 and usually by LOS I'm decoding\nnear 145.822.\n\nWith the smaller tuning steps of the FT-857D I am able to decode about 30%\nmore packets than my TM-D700.\n\nSimply put, in the past a fixed station could stay on 145.825 MHz with\ngreat results. Today, not so much.\n\n73\nClayton\nW5PFG\nOn Jan 1, 2015 9:10 PM, \"Kelley\" <[email protected]> wrote:\n\n>\n> I put up a new antenna for ISS work today.
