This is part of a larger project to try to bring FT8 and MSK144 to analog FM transceivers (paired with an RTL-SDR), much like how MMDVM brought M17/DMR/D-Star/YSF/NXDN to analog FM transceivers. If successful, it should drive down the cost to set up a station for the #hamsci Meteor Scatter QSO Party (because it's now legal to use MSK144 on 10m!) that's coming up in August and December.

I came across theblog of KM1NDY this morning (via Amateur Radio Weekly) and read this nice post about #hamsci I particularly love the journal article write-up!

Just completed another great #HamSci conference at my old stomping grounds; at #NJIT. (I did a summer "Intro to Engineering" program there during High School back in the 1970s.) My head is still buzzing with ideas. 1/n

Her #GRCon24 Keynote has started, so Kristina Collins KD8OXT presents about what it is about The Lion In The 𝙋𝙧𝙤𝙥𝙖𝙜𝙖𝙩𝙞𝙤𝙣 Path, how we can find wisdom in the ionosphere, asking how to build scientific / engineering community cooperation. She's discussing the nature, uses, abuses and fun to be had with space weather science.

Kristina Collins, scientist of very long, very flowing hair, with her hand raised, communicating science, standing at a speaker's desk. She seems (and is) very enthusiastic about what she's talking about.

@bud_t @wb2ifs @thenrao and of course the friends we've made along the way in @hamradiosci @arrl #HamSCI The #HamRadio #AmateurRadio community stepped up to make this release real!

I’m working on a grant for a #crossgenerational #colearning project involving #bipoc youth and I’m issuing the following challenge: Tell me about a time when you learned something new and exciting from a young, BIPOC, person or student. What was it? How did they teach you? #blacksinstem #stem #stemm #steam #blacksinscience #blackmasodon #physics #astrophysics #heliophysics #hamsci

@Geojoek @kr1st absolutely. #hamsci has presented and I gave an oral presentation. Here’s the video I submitted https://youtu.be/xSYOd17HnGU?feature=shared

I promised some data, and here it is!

I didn't record the actual sound unfortunately but you can see a massive discontinuity in the noise floor at just before 6 AM Pacific time (America/Los_Angeles) followed by highly unsettled noise floor conditions for the remainder of the day.

The next graph picks up again after midnight (and unfortunately stops just before 7 AM because the battery voltage got too low and my radio switched off). You can see the unsettled conditions start to simmer down again by about 5 AM.

This looks like it MAY have correlated with a solar flare that peaked at 7:55 AM Pacific (14:55 AM UTC). If so, it's a fascinating and unexpected result! I just wanted to chart the noise my local power company is making!

A graphical plot comparing the intensity of 120pps powerline noise and the noise floor on the 80 meter amateur radio band, with a sudden discontinuity in the noise floor followed by very unsettled and chaotic conditions for the remainder of the day.

A graphical plot comparing the intensity of 120pps powerline noise and the noise floor on the 80 meter amateur radio band, with chaotic conditions for the noise floor for most of the evening until around 5 AM when they started to settle back down again.

Still collecting data for the Gladstone Challenge for HamSci. It was neat to "win" in October, don't expect to for this ecplise since I was near the path of totality. We'll see. But it's all good data for science! #hamradio #hamsci

I've got everything set up and ready to go for the #HamSCI Solar #Eclipse QSO Party! I'll be participating between 1600Z and 1900Z mostly on CW. #AmateurRadio #HamRadio

Is anyone planning on doing any particular radio stuff during the eclipse?

I found this list of ideas:
https://hamsci.org/eclipse

I've driven down to Dayton, OH and plan to be somewhere in the path of totality with my FT-817 and MFJ-1899T tomorrow.

Might try doing some kind of radio experiment or data gathering, but very much vacation style. Main goal is to experience the eclipse with family.

Looking at setting up the following insruments once back in the US, Ham Sci Grape Space Weather Station, Muon Detector, PWS WX Station, a Raspberry shake (RS4D | Strong Motion Seismograph) & a VLF Receiver as a part of the Ham Station/Astro Observatory. So on the other "SLU" https://www.eas.slu.edu/eqc/eqc_netrt/eqcnetrt.html #hamradio #astronomy #skywarn #hamsci #muon #VLF

At #hamsci I was reminiscing with other #hamradio operators about getting #radiograms from “random” #hams who noticed that you upgraded or just got licensed. I want that for our learners! Who do I need to talk with to make this happen?

Great times at #HamSCI last week end. Thanks so much for welcoming our students. #HamRadio We really enjoyed #thinkbox and working 40m from #w8edu
