If the YouTube video is acting glitchy to anyone please let me know and I'll re-upload the video. For some reason it's not playing correctly on my computer.

Good catch, the video worked fine for me.  You wouldn't happen to be the same peter jennings that has a college radio show in Ohio, would you?  https://www.facebook.com/pages/The-Cream-of-Broccoli-Radio-Hour/265761019152?hc_location=timeline

Are you sure it was in USB mode?  HM01 is almost always in AM, but of course there are sometimes mistakes.

Going to go over some basics here, if you already know this just ignore what I type.

When receiving a station you should always try other modes to see if it is really in the mode you think it is.  It is possible to receive some modes in "other" than the mode they are transmitted in.

A station that is transmitted in AM can be received equally well in AM, USB, and LSB.

A station transmitted in USB will only be clearly heard in USB, and the same for a station in LSB, it will only be clear in LSB.

A station that is transmitted in SSB (either USB or LSB) plus carrier will be received in that SSB or in AM, but will not be received in the opposite sideband mode.

CW can be interesting, depending on your exact radio.  CW can be received equally well in CW, USB, or LSB modes, but will indicate incorrect frequencies in USB and LSB mode, or if you are not tuned to the exact pitch in CW mode.  The key here is that with CW signals your freq might be off by quite a bit, so if someone else reports it on another freq keep that in mind.  Or if you are looking at freq lists keep it in mind.  If you are receiving CW in SSB mode (either LSB or USB) consider that the actual freq might be +/- 2 kHz.

Hope that helps.

Yes I am! I used to have a weekly radio show, but now I do a monthly rotation slot.

I was so excited to hear the broadcast that I completely neglected to rotate through the modes. The next time I catch it I will definitely do that.  Thank you again for your help!

Holy shiznit, I love your show and catch it whenever I can.  Welcome to the underworld of broadcasting, LOL.  Do you also chase pirates?

I'm in Mentor and enjoy radio immensely - I've got lots of HM01 and other cool sw stuff on my youtube if you ever get bored.
