Just wondering if someone can confirm actual altitudes above 35k ft (~10 km) tracked with the TM and its standard 1/4 wave  wire antenna and a yagi on the rx side.
I saved this comment a while ago but cant remember where i saw it:
"Tests performed at Altus Metrum have shown that a 3-element yagi antenna yields good telemetry from rockets to 20 Km (65,600 feet) altitude, and that a 11-element yagi antenna can receive telemetry from the TeleMetrum to around 100 Km (62 miles)"
Has anyone flown above 35k ft yet with a TM and maintained good reception?
