You can check out SSB here Gary:
http://hackgreensdr.org:8901/
That link covers the Ham bands, not sure what antenna they are using or if it's directional, below 10 Mhz should be on LSB, above 10 Mhz should be on USB, 40 metres is good for most times of the day, 160 meters "Top Band" and 80 meters are normally best at night time, 160 metres is low power for UK operators and often has a lot of interference, 20 metres before 9.30 am might bring in some Australian/NZ transmissions but at night time USA Hams can normally be heard, if you get bored there's always CW to keep the brain alert...
Here's the link for Websdr home page:
http://websdr.org/
Some of the receiving stations listed in that link might not be operative, the controls on these sites are easy to use and mainly self explanatory, you can fine tune the signal down to a very good resolution, some of those sites might cover other frequencies other than the Ham bands if you are interested in military or oceanic HF (commercial airline communications) The USB/LSB convention can vary with with non Ham transmission so the below 10 Mhz for LSB and above 10 Mhz for USB won't always follow.
Shanwick is the easiest oceanic hf to receive, one of it's counter parts, Gander can be received at night time. The easiest Shanwick transmissions to receive are normally the ones in the 5 Mhz band just above Shannon Volmet, Shannon Volmet was around 5.505 Mhz last time I heard it, if you see a line on the waterfall display just upstream of Shannon Volmet it might be Shanwick, be aware that some Shanwick transmissions are very very short so be quick on the dial as it were..
