Nice change from the last \ntwo responses to my post. Second of all, I apparently stand corrected \non one thing. It was my impression that Fox-2 was also intended to be \nanother FM sat. If I am wrong in that then I apologize for the previous \ncharacterization that all AMSAT seemed to want to do is put up \"flying \nrepeaters\". However, I will not back off my assertion that there should \nbe more to this hobby than portable ops using HT's and handheld \nyagis. The Funcube bunch showed us not only that linear cubesats are \nviable but also that fairly inexpensive SDR technology is a great way to \ngo as one option in receiving them. The Funcube and Funcube Pro \ndongles were also a great fundraising idea as near as I can tell. We \nshould be taking concepts like that one step or even several steps \nfurther and developing SDR based ground station solutions just as we \nare developing SDR based transponders. Why AMSAT is not developing \nstuff along those lines is a mystery to me. I know AMSAT is volunteers \nbut so is AMSAT UK and they got it done. I wish I had the technical \nexpertise to develop stuff like that but I don't. I can certainly \nbuild with the best of them but circuit development is not my strong \nsuite. It just seems all we ever do anymore is show folks how they can \noperate an \" easy sat\" with an HT. That's very frustrating to me. I \napologize for the \" idiot at a hamfest\" comment too but really all I \nwas trying to do was to express my frustration with that same old \napproach which has grown kind of tired and boring to me.\n73,\nMichael, W4HIJ\nOn 1/26/2014 12:41 PM, n0jy wrote:\n> Hi Michael,\n>\n> I have to defend AMSAT-NA a bit here, the perception that the \n> organization is \"bent and determined to keep building and flying FM \n> repeaters\" is not quite accurate.\n>\n> Fox-1 which is an \"FM repeater\" was underway over 3 years ago when \n> AO-51 was failing.
