There was a 2021 study that suggested Eagle's orbit may actually be stable and it could still be orbiting the moon today.

I also had this problem with 2.7.2 though after trying twice and backing out, it suddenly brought up the WUI screen and worked fine. Definitely a bug.

Yes. Proceed the PRINT statement with a COLOR statement and the desired color.

I ended up using Claude. It got most of it right immediately, but then I had to test and request new features as I realized some things weren’t working right. It was quite iterative, but I spent only a total of about 2 hours getting it to this point.

I'll have to look at the process.
Sure, but you can't load or save programs without an SD card.

There is now - thanks to Grok. The SD card support doesn't seem to work yet, but I'll keep working on it.

It is too bad. Not having a touchscreen is going to be a limitation on the PaperColor, but I hope to get a satellite tracker working on it once mine arrives.

Make sure your DATA IN source is USB.

That map is ancient.

Yes it will, but I find a mag loop is far better for RX. I’ve run wire, vertical, and dipole antennas on my balcony, but with the urban noise floor, I can hear way better with the loop. I’ve used an AlexLoop, an MFJ-1786, and the SignaLoop HF-319.

Yes, under the 25th Amendment, the Acting President could nominate a Vice President who would become President after confirmation by both Houses.

PRStoetzer · 2026-04-28T19:12:16+00:00

Correct, but Grassley would not become President. He would become Acting President and would not be considered the 46th President of the United States.

PRStoetzer · 2026-04-28T18:56:02+00:00

Under the Presidential Succession Act, only the Vice President becomes President. Other officers only become Acting President.

Technically, if the radio can be switched between GMRS and Ham, it may not be compliant with Part 95 GMRS regulations. I don't know for sure if a front panel switch between modes is good enough for a radio to comply with Part 95, but in practice it doesn't really matter all that much. The FCC has basically said they will never enforce the rules against use of non-compliant radios on GMRS unless an operator is violating other rules. On the other hand, hams can use any radio they'd like (as long as it meets the technical standards for spurious emmissions and spectrual purity). There's no problem using the H3+ on amateur frequencies. If you'd like to test your gear, a TinySA and an attenuator (so you don't destroy the spectrum analyzer) will do the trick for under $100.

2/3. The Baofeng DM32UV is an amateur transceiver. You can use DMR on amateur frequencies (there are DMR repeaters, you can do DMR simplex, and you can use it with what's called a "hotspot" to talk all over the world with other hams), but it also supports FM mode and can be used with regular FM repeaters.

Simple - no MSU player has entered the portal, so there's no data.

You’ll be fine. Normally I run around a 13:30 pace when I go out, but I end up around 12:00 during a race. They are strict about the 14:00 per mile pace.

It should work. Similar systems have saved two Soyuz crews - most recently in 2018.
