We’re trying something new this time: floating a tethered balloon with an ESP32-CAM that will transmit SSTV images on 20m, frequency 14.236MHz USB Mode Martin-1. This is a project that Kazu AG6NS has been working on recently, with some help from Martin W6MRR.
To see this in person, go to the northern area of the Berkeley Marina as indicated around the position identified on the map link below:
After a series of failures to send after launching, there seems to be an intermittent problem with the same tracker. It is alternating on 20 and 40 m, with most of the 40 m transmission lost. We test on the ground prior to launch and never have problems. It may be temperature related problem due to counterfeit parts.
We’re launching a pico balloon this Sunday morning, January 30th at 9:00 AM pacific time. If you’re in the area and would like to see the launch, please join us at the Berkeley Marina on the north side on Marina Blvd. See the map link below for the location.
There were a few final position reports on 2021-12-23. The balloon had not crossed the Intentional Date Line but has gotten further than previous attempts. The last signals were received by CA stations so at least my signals circumnavigated.
We’re launching a pico balloon this Saturday morning, December 11th at 9:00AM pacific time. If you’re in the area and would like to see the launch, please join us at the south-west area of the Berkeley Marina. See map below for location.
