Wow! The high altitude weather balloon 🎈 launched by my friends in San Diego has an incredible number of ground stations receiving it!

The Villanova University ARC W3YP ground station is receiving telemetry 📡 from the KB3ZOX reflashed RS-41 radiosonde high altitude balloon 🎈 as it flies up the east coast.

A little email frequency coordination was needed to make sure everyone on 431.05 MHz!

I enjoyed doing this interview with Eric Guth, 4Z1UG/WA6IGR for his QSO Today podcast.

He got me talking about how I got started in amateur radio, how it influenced my career choices, my satellite work, my educational outreach using the AMSAT CubeSatSim, and high altitude balloon launches. He even asked about my standards work in the past with Session Initiation Protocol SIP!

This is one of the GPS trackers on the balloon. 🎈It transmits on the standard frequency of 144.39 MHz into a twin lead J-pole antenna. The Raspberry Pi Pico reads the BME280 (temperature, pressure, humidity, altitude) and MPU6050 (gyro and accelerometer) sensors. The transmitter is an SR_FRS_0V5 FM module that transmits 500 mW. The PCB is a Beta V2 board. The GPS is a LC76G with a dipole antenna.

Predictions for Wednesday’s high altitude balloon launch by Villanova students looks great! This is from predict.sondehub.org

I’ll post about the amateur radio and tracker payloads tomorrow.

@ku2y I expect that which ever ham balloonist lost their kit to NORAD said the same thing ... :-)

I'm not into the whole balloon scene (as fun as it seems!) but every launch I've seen promoted has always mentioned the FAA notifications. I'd be surprised if the one(s) shot down *didn't* file. But I'm sure the owner is still in an Undisclosed Location - I would be!

University students will be launching two high altitude balloons Wednesday May 3 around midday. We will have & GPS trackers, live images, & a !

I will post links to the trackers here so anyone can follow along. If you are a ham or have an SDR or scanner in the Philadelphia/New Jersey area, I’ll post the frequencies so you can listen.

Wish us luck! 🎈📡👍🏻😁
