    "content": "Hi Scott,\n\nI can't speak for John K8YSE either, although he does very good at\ngetting into the birds.  One thing that does help is that he has\ntwo stations, K8YSE in EN91 and K8YSE/7 in DM43, which he operates\nremotely.  I actually listened to him work BY70-1 and SO-50 from\nboth stations on a single pass.  Can't speak to the TX power or\nantenna configuration he has.\n\nI have been pretty successful with getting into BY70-1 with the\n7W TX power on my satellite 'battle station'.  There are a couple\nof things to keep in mind regarding working BY70-1:\n\n1) The TLEs of BY70-1 are changing rapidly, so it is advised to use\nthe TLEs provided through Celestrak New Launches.\n\n2) The low perigee of its orbits makes for wickedly fast passes.  I\njust worked one that was 8 minutes long.  I worked one a few days\nago that passed almost directly overhead and was a little over 6\nminutes.  Antenna pointing agility/accuracy are important.\n\n3) It has been stated that BY70-1 has a narrow RX bandwidth.\nTherefore, it is necessary to adjust your TX frequency often to get\nin.  On 12/29/2016, I posted a suggested frequency list for use with\nchannelized radios that I have found to work well from my own\nexperience.\n\nHope this helps.\n\nMac Cody / AE5PH\n\nP.S. We had a QSO back on 12/22, so I recognized your call sign.\n\n\nOn 01/02/2017 10:13 PM, Scott wrote:\n> Happy New Year to everyone.\n>\n> So for the second evening in a row, as I monitored BY70-1 for telemetry packets, I noticed performance on the FM voice transponder that prompts me to ask a question.\n>\n> Specifically, I hear K8YSE getting into the satellite with a crystal clearness that you would expect from a simplex QSO with someone in your front yard.

Maybe it’s just a lot of football on TV!\n>\n> I know that any answer might be speculation, but when I hear something happen on the air repeatedly it makes me want to see if I can learn the cause (or possible causes).\n>\n> Thanks!\n>\n> -Scott,  K4KDR\n> Montpelier, VA\n> twitter:  @scott23192\n> _______________________________________________\n> Sent via [email protected].
