    "content": "KC9DOA mentions that he still had the birdie\nproblem with a downconverter and that is understandable.\nThe TS2000 radiates the birdie and if your downconverter\nis not shielded or the UHF antenna is too close to the\nradio, you might still pick it up.  Simple experimentation\nwill find the right combination to virtually eliminate the\nbirdie.  So try a UHF handi or mobile unit and see if it\nhears the birdie on 436.798.  Then move things around to\nsee if you can minimize the effect.  I've been able to do\nthat in the sat truck and don't have the problem at the base\nstation.  Try a dummy load on the UHF antenna jack on the\nTS2000 as well.  Use quality coax with good shielding.\n\nDrew posted a link to High Sierra Microwave for a UHF down-\nconverter that is up-to-date in design and performance, all\nat a reasonable price.  The specs call for a 5v supply but\nBill N6GHZ advised that the converter will operate fine up\nto 16vdc input.  No special supply required.  He also mentioned\nthat the converter will perform well from 432 to 438 MHz.  So this\nis one possible source of a current production downconverter\nmanufactured by someone who knows satellites.  The output IF is\nlower but the TS2000 receiver is continuous so there should be\nno problem.  Instead of a 407MHz offset, use 425MHz and the receiver\nshifts down to 10MHz for a 435MHz input:\n\ndoppler.sqf entry:\nAO-27,436795,145850,FM,FM,NOR,425000,0\n\nI've not seen a whole lot mentioned about the Funcube performance\nwhen connected to a big antenna in a crowded RF environment.  I've\nhad mine on the KLM's and the performance is poor because of\noverload.  Cavity filters work wonders but not everyone has them.\nHigh Sierra also makes front end filters and filter/LNA combinations\nfor the Funcube as well as other products which make the Funcube more\nversatile.  It's worth checking out the webpage to see what is\navailable.\n\n73,\nJohn K8YSE  \n\n",
