HF? Apollo didn't use HF, so I wouldn't expect Artemis to do so.

If you are interested, look up Curious Marc on YouTube. He has a whole series about restoring Apollo communications equipment. The technology they used in the 1960s is fascinating.

As a young boy in the 60's, I was fascinated by the Gemini and Apollo missions and the use of Quindar tones.

Regarding radio comms, I came across this article regarding the Artemis 2 mission and the use of Optical Communications Systems. I was not aware of this technology and find it fascinating:
One of the new additions for Artemis II’s Orion spacecraft is the Optical Communications System O2O hardware, a DTO (detailed test objective) flying on Artemis II. The Optical Communications System2 is an infra-red laser based communications system that has been in development since 2013 by NASA in partnership with the Massachusetts Institute of Technology’s Lincoln Laboratory.

Another fascinating presentation (pdf):
Optical Communications for Artemis II Crewed Mission

Some technical info and frequency information here for hams volunteering to track Artemis 2:

Can't find specific info for voice communications, but a bit more here on communications technology and specific frequency allocations in the 2nd link.

Wideband Polylingual Terminals - use of SDRs:
wideband polylingual terminals use
software defined radios to enable
similar roaming capabilities in space,
empowering spacecraft to move
between both government and
commercial frequencies.
Terminal Details
• SWAP: 24 x 24 x 17 inches, ~23kg weight,
peak power 200 watts
• Operational Frequency Coverage: 17.7 GHz-
23.55 (Forward) and 27 GHz-31 GHz (Return)
• EIRP: 46.21 dBW (Minimum)
• G/T: ~6dB/K
• Waveforms: DVB-S2, CCSDS TDRSS
• Data Rates: up to 90 Mbps (Forward)
and up to 375 Mbps (Return)
• Future Data Rates: up to 490 Mbps
(Forward) and 1 Gbps (Return)

I have no need for a history lesson. Im asking about flight's from 2022-2026 missions. My best guess 12.222 USB. HOMEPLATE FLA. has had recent HF radio comms. Will be monitoring each day. Worth it.

From my research, three of the four astronauts are licensed hams - Artemis 2 astronauts flying to the moon could phone home with ham radio:
  • Reid Wiseman (KF5LKT) - Technician
  • Jeremy Hansen (KF5LKU) - Technician
  • Victor Glover (KI5BKC) - Technician
...so they would be limited to Technician's privileges.

According to the article: ..."astronaut Christina Koch, was studying for a 2019 amateur license exam when her record-setting one-year flight was abruptly rescheduled six months earlier than expected, according to the National Association for Amateur Radio. Koch delayed the certification in favor of completing the mission training for her 328-day sojourn that ended on Feb. 10, 2020."

She may have completed it in the interim but I cannot find a reference.

Anyone in the area need to listen for activity on 259.7 and 296.8. These are the old standby freqs used by Apollo all the way to the last shuttle mission. I would guess they will use the standard UHF on launch just like the shuttle until they hand off to TDRS in orbit.
