I've listened on there quite a few times, generally via remote online SDR receivers (due to local noise levels).
My magnetic loop antenna covers the band easily, but many of my radios are either single band QRP rigs, or else they are (the older, more traditional) Amateur Bands only ones. Some of them simply will not transmit outside of the original frequency ranges they were intended for, or else the ones that do have fairly narrow passband filters on the output stages so any 60m signals become greatly attenuated.
I've seen a number of transceivers where the LPFs have been burnt up due to their owners transmitting out of band (very often folks trying to use the 10m range down on 11m for CB Radio).
Is 60m rigidly channelised in the States as it is here in Europe? That's one of the things I've always been worried about, accidentality transmitting out band (or 'out of channel') on 60m.

Reading around it seems that in the US you have five 'channels', but the UK has seven or more? :-*
USA = http://www.arrl.org/60m-channel-allocation
UK = https://rsgb.org/main/operating/band-plans/hf/5mhz/
There is no way I would remember those 'in anger'. I would definitely need a printout of the requirements in front of me while operating on 60m. bd

Like Mark, I have to look up the 5MHz frequencies before I use them.
Had a few inter-G CW contacts.
My local Raynet group ran a very local 5Mhz USB net for a while - living in the highlands VHF/UHF, even with a temporary repeater, is challenging so we thought 5MHz with NVIS low horizontal antennas might be a backup for local working. It does work with such an antenna, but my home antenna is a vertical and I really struggled.
I vaguely recall there was a non-amateur 'Alaskan Emergency Frequency' around 5MHz for folks out in the bush.

I remember googling the Alaska Emergency Frequency when I got my '817. I didn't find much, but now all is explained (hat tip to W5TXR for the info below):
FCC Part 97.401
Alaska Emergency Frequency
? 97.401 Operation during a disaster. A station in, or within 92.6 km (50 nautical miles) of, Alaska may transmit emissions J3E and R3E on the channel at 5.1675 MHz (assigned frequency 5.1689 MHz) for emergency communications. The channel must be shared with stations licensed in the Alaska-Private Fixed Service. The transmitter power must not exceed 150 W PEP. A station in, or within 92.6 km of, Alaska may transmit communications for tests and training drills necessary to ensure the establishment, operation, and maintenance of emergency communication systems.
A few have asked me if I knew anything about the "Alaska Emergency Channel/Frequency"5.167.5 Mhz USB Most (perhaps all) HF radios on the market that include the 60 meter band include the option of enabling the "Alaska Emergency Frequency" I know that my Yaesu FT-950 and FT-897D both have it enabled. I've actually heard people using the frequency in Alaska. I know that Alaska State Troopers monitor that frequency because I have heard them. They along with the Coast Guard and other civil and municipal organizations monitor too.
A amateur radio license is NOT required to use this frequency. But hams can use it along with any other Alaskan within the legal boundaries of the FCC rules. I have learned that many other people also monitor like people that are isolated and usually someone in a isolated village will monitor too. I think it's a great idea, too bad some of the larger states does not have a designated frequency i.e. Texas, Montana, Wyoming, North/South Dakota...
