I have gone back to #ARRL jail with my most ridiculous #QEX article to date. Probably low probability of publication, but you gotta try, right?

An article about our Opulent Voice project has been published by #ARRL #QEX

Let us know what you think of the article.

This Month in QEX

The American Radio Relay League (ARRL) is the national association for amateur radio, connecting hams around the U.S. with news, information and resources.

Today in the lab at @OpenResearchIns we are working on the uplink receiver design for an #opensource #amateur #satellite.

The residual doppler is +/- 12 kHz, the signal itself is <40 kHz (some overhead is still to be integrated in the uplink protocol) and the uplink channel width is 100 kHz.

The uplink band is 10 MHz, and the baseline frequency plan is 5 GHz up and 10 GHz down. We have another RF plan for 10 GHz up and 24 GHz down, and 47 GHz up/down.

Article about uplink FEC in #QEX soon.

My latest #QEX article was published today in the January/February 2023 issue. Out now in the #ARRL digital magazine app.

A co-authored article with one of my students. It's his first article.

It happened again.
Back to #ARRL jail.
Got another #QEX article accepted.
This time, it's not a solo article! I co-wrote it with a student of mine. So that's nice. It's his first publication.
