I made a couple last time home which surprised me.
Radio: IC-718. I found a couple of garbles I couldn't tune in so I swapped functions from LSB to AM and Presto! QSO. There are more out there than I thought that are still running AM rigs. WHile not a whole lot, you might try switching modes if you can't seem to tune someone in. The one I remember most is this yayhoot in VT that seemed to be a combination of being a victim of 11 generations of inbreeding coupled with an MIT triple PhD egghead. He wanted to yak about theoretical quantum physics while I wanted to take a wicked real world shit. I had to break the chat off fast. Another reason to not be able to tune the garble in on 40 and 80 meters is that the guy may be using a military rig on USB. I can't go with USB on 160, 80 or 40 on the IC-718. Next time I'll keep the USB 320 nearby. Something to think about. |

AM is a blast. Lots of guys on there if you look for it, running everything from vintage rigs to new a new Flex. Some with super broadcast quality equipment. I like to have an AM QSO now and then.
Back to furiously looking for pics of a ham operator sitting on a toilet in his shack to post in this thread... ETA: Lift the seat, Pic. http://www.waffleshopbillboard.org/?p=101 |

had on on 40m one day. spinning around and heard garbled CQ. answered, nice QSO to AZ. he couldn't believe I was 100w on Random Wire :) posted about it here. was struck buy the "sound". I loved it and snoop around hoping to find another!

Something to think about. really?? what if you wanted to do 80m digital? the radio won't allow it? that just knocked it down on my list a bit if true...... and I've thought of having an "off sideband" net once or twice....

You were probably hearing his upper sideband (an AM signal is an upper sideband, a carrier, and a lower sideband). I can't go with USB on 160, 80 or 40 on the IC-718. Next time I'll keep the USB 320 nearby.
According to the manual, you should be able to: "Push [MODE] for 1 sec. to toggle between USB and LSB". |

an AM signal is an upper sideband, a carrier, and a lower sideband
Elaborating further, if you look at the power distribution of an AM signal, the carrier is 50%, the upper sideband is 25%, and the lower sideband is 25%. If you suppress the carrier, the upper sideband is 50% and the lower sideband is 50%. If you suppress one of the sidebands, the remaining sideband is 100%. So SSB is 4 times (6 dB) more efficient than AM, and uses half the bandwidth. |
