W6MRR-20 was approaching Iceland and stopped sending at sundown. It’s altitude was reporting between 1 W (9,000 m – 9,900 m) and 2 W (9900 m – 11,100 m). It must have developed a leak.
Today we had an interesting launch. Windy.com’s predictions were promising but we waited and waited for a lull. We were shooting for a six g net lift. We thought we were okay with about a 60 degree angle. On release the wind took the balloon sideways and the lower dipole dipped in the water. ItContinue reading “KF6ZEO-12 Launch”
W6MRR-20 was launched at 9 am PST October 9 from Berkeley Marina. It was transported overnight from NW Los Angeles to the Great Lakes. I am using new software to send Type 3 WSPR messages for better location but there’s a bug in the The AMSAT Argentina LU7AA website is really interesting – check itContinue reading “W6MRR-20 Visits Great Lakes/Canada”
We will be sending balloons from the Berkeley Marina There is a bug in the software so it is sending on 20/30 m on alternate transmissions. I am testing with just a short wire and am receiving it fine so it will be interesting how it does with a 20 dipole. Tune in for K6RGGContinue reading “Launch on Thursday @ 11:30 AM and Saturday @ 9 AM”
Robert K6RGG and I launched a pico balloon from the Berkeley Marina at noon, Monday September 20. It didn’t start sending so I gave up. I was alerted to beacons received on September 22 over the Pacific in grid square CL20. It was received by the amazing KFS receiver. It was and continues to reportContinue reading “Where is W6MRR-19?”
Miniware MHP Mini Hot Plate – I bought a cheap reflow oven but it was broken when received and never replaced. I mostly hand solder or use a hot air rework tool. This seems like a great tool for hand assembling and rework. There are three preset temps that are preprogrammed but can be changedContinue reading “New Toy!”
Last transmission at 2021-09-19 05:22 UTC. It seems to be sitting on the ground in Turkmenistan and a packet was received in Finland.
wspr.rocks Reception Report – Where are all the hams to the east? 10 Day Hysplit Prediction
The WSPR power field is used to convey altitude. (I’m using a 10 mW output into a dipole). The latest data can be found in the WSPRnet database. The WSPR data is transferred to APRS.fi with this format: RX_UTC_day RX_UTC_time Callsign Frequency_MHz RX_SNR_dB RX_drift TX_gridsquare TX_power_dBm RX_callsign RX_gridsquare RX_miles
