That said; the best recent-manufacture full-duplex dual band HT is\nthe Kenwood DH72. I personally prefer 2 separate HTs (it eliminates any\nchallenges with hitting the wrong buttons). I've used 2 Yaesu HTs I've had\non-hand, a VX5 and a VX8. The biggest challenge has been rigging a wiring\nharness to allow me to use a headset with 2 separate radios (many\nHT-oriented headsets mold the RX audio into the same connector; the Heil\nBM17 series is much better in that regards) and put an audio recorder\nin-line or in parallel with RX audio (while it would be nice to hear my TX\naudio at a proper volume, if I make it through the satellite, the d/l us\ngood enough for logging the QSO afterwards). To make it easier to manage\nthem, I modified a small clipboard to hold the 2 radios and an old Android\nphone running tracking software from a camera strap; this makes it a lot\neasier to manage the antenna, radios, etc without running out of hands!\n\nI'd say any recent manufacture Icom, Kenwood, or Yaesu HT will work well.\nThe Baofengs, etc. seem to be mostly prone to RX desense, especially on\nmode VU Birds (SO50, AO27, LilacSat2 (when operating)). Less of an issue\non AO91, 92, PO101.\n\nAnother option: Older smaller dual-band mobile rigs that are full duplex.\nKenwood TM700 and older 710s (before GPS was integrated into the radio).\nAbility to go to 5 or 25w handy on rough passes. With radios like the 700\nand 710 that have detachable front panels, you could stuff a battery and\nthe main unit in a shoulder bag or backpack and mount the control head on a\nchest harness or strap. Or run the whole thing from a table mount, up to\nyou. You do give up portability vs HTs.\n\nIf you already have an HT, use it and get another for the 2nd band.\nClint's had good success with older Yaesus, per his work-sat web pages.\n\nIf you use a single full-duplex radio, you will need a diplexer to split\nthe VHF and UHF sides for antennas like an Arrow (unless you buy the\nversion with a built in diplexer and keep power under 10W!). Or use a\nsingle-input dual band antenna like the Elk. If home brewing, simplest is\na pair of 2M and 70cm yagis, Arrow style. The WA5VJB \"Cheap Yagi's\" are\nvery easy to make, trick is making them light enough if you want to hand\nhold them. If you use a tripod, ability to quickly adjust polarization to\nmatch the satellite is essential - I can null out a downlink by twisting my\nArrow the \"wrong\" way.\n\nHope this helps, there are several experienced operators responding to your\nemail.\n\n73 Steve KS1G\n\nOn Sat, Jan 2, 2021 at 11:44 AM Gerald Payton <[email protected]> wrote:\n\n> Such a simple question but I am a loss finding an answer.
