A nice mention of my education project on Science Friday:

"Besides his engineering classroom where all the theoretical work is taking place, Grace Brethren also has a Space Lab where students work on building things. Every year they try to create a CubeSim."

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!

That was an amazing high altitude weather balloon flights yesterday by the University Club!

Here is the dashboard summary of the flight from Sondehub.org:

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.

@ku2y Thanks for that information! I just used the Lite to set up the MMSSTV software using the IC-9100. Got the calendar blocked off for lunch tomorrow and the satellite antennas are pointed South, ready to see if I can catch some SSTV images up here in NE PA. Good luck to the Villanova University Club!

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.

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! 🎈📡👍🏻😁
