Should every packet heard and seen in the waterfall decode to a \r\nmessage? I get a bunch that don't decode even when the RX signal is \r\nstrong. Are some packets telemetry packets? I'm trying to determine if \r\nI have a RX issue or if this is normal.\r\n\r\n2. I'm getting RX signal fading akin to tumble fading. I pretty much \r\nquit having this type of fading on all other birds when I upgraded to a \r\ncircularly polarized antenna. GreenCube will fad out and back in about \r\n6-10 times per pass (2ish minute cycle). Is this to be expected? Are \r\nothers hearing this?\r\n\r\n3. What transmit power is appropriate? On the horizon it seems fairly \r\nclear that running the IC9700 at full power isn't excessive but what \r\nabout when the bird is closer to overhead. Is GreenCube like other \r\nbirds and best to run at the minimum. It has been difficult for me to \r\ntell what I need to dial back to when overhead, if indeed I need to.\r\n\r\n4. Why is the bird sometimes in 300bd mode and other times 1200bd? Who \r\ncontrols this? I find I prefer the 1200bd as the packets are shorter \r\nand present less time to be corrupted by something - like a doppler update.\r\n\r\n5. I'm finding I TX better than I RX. I'm thinking I want a LNA at my \r\nantenna. Is anyone successfully doing this? Which LNA and can it be \r\npowered by the IC9700?\r\n\r\nThanks all\r\nCal - N7AY\n\n\n", "attachments": [ { "email": "https://mailman.amsat.org/hyperkitty/api/list/[email protected]/email/OLL2FV7WUEFOTNUI4ZDAYPFRUE23LJPL/", "counter": 2, "name": "attachment.html", "content_type": "text/html", "encoding": "utf-8", "size": 2254, "download": "https://mailman.amsat.org/hyperkitty/list/[email protected]/message/OLL2FV7WUEFOTNUI4ZDAYPFRUE23LJPL/attachment/2/attachment.html" } ] }
