DIY: Build a 70cm Band Yagi for Amateur Satellite Tracking

Its been a long time since Ive chased any amateur satellites. Its been a long time since Ive had the time to chase them, and sadly, things have changed. In the seven years or so, satellites I once knew as friends were no longer operating as they used to some had partial failures and unpredictable schedules due to battery failures, others were completely failed and never to be heard from again. Even though they were designed using commodity hardware on shoestring budgets, and most of them well outlived their design lives, those damn inanimate objects certainly worm their way into your heart if youve ever spent some time chasing them and heard some QSOs, or even just the reassuring telemetry beacon.”
