If you only adjust your transmit frequency, such\nthat your receive frequency appears to stay the same -- then you're\nautomatically correcting for your own downlink doppler, but not for\nanyone elses. Other hams in the footprint will still have to chase\nyou. The only way to stick with the \"one true rule\" is to adjust\n*both* uplink and downlink during the pass.\n\nThat being said, adjusting the higher (UHF) transmit frequency on\nVO-52 and AO-07 only (ie. manual control) will get you pretty close,\nand you won't drift a whole lot. I hear plenty of hams doing this, as\nlong as there are just one or a two QSO's going on, they don't drift\ninto each other very often.\n\n73 de Dave KB5WIA / CM88\nSatPC32 with 2xFT817ND\n\nOn Thu, Jun 9, 2011 at 7:35 AM, <[email protected]> wrote:\n> OK my brain may be playing tricks, but if you vary only your transmit\n> frequency such that you always hear yourself on the same downlink\n> frequency, isn't it true that the other station may not necessarily be\n> hearing you on the same downlink frequency and is chasing you anyway?\n> Your doppler is +5kHz (for example) on the receive, the bird is just about\n> to pass overhead of me though so my receive ferquency goes rapidly from\n> +2kHz to -5kHz, your transmit tuning has no relation at all to what\n> frequency I am listening on.
