AO-92 L-band demo by N8HM at Hamvention John Brier, KG4AKV, has produced a video showing Paul Stoetzer, N8HM, working AMSAT-OSCAR 92 (Fox-1D) in L/v mode (1267.359 MHz uplink, 145.880 MHz downlink) using AMSAT's club callsign, W3ZM/8, at the 2018 Dayton Hamvention:
There are cameos in the background of the video by fellow AMSATers Marty, N9EAT, Ruth, KM4LAO, and others!
Equipment used was an Alinco DJ-G7T 144/430/1200 MHz handheld trans- ceiver for the uplink and a Kenwood TH-D74 handheld transceiver to receive the downlink. The antenna is a Comet CYA-1216E yagi with holes drilled in the boom to accommodate the three 2 meter Arrow Antenna elements.
The antenna rotator system behind Paul/in front of the tent is a commercial system by Portable Rotation:

He was not using it for this demo but it was tracking AO-92 during that time.
Aside from this L-band demo, Paul used that for all the other AMSAT satellite demos during Hamvention 2018. He had two Yaesu FT-817 radios on the table and a computer controlling the rotators/antenna.
The antenna attached to it is the Alaskan Arrow II.
