Oh yes I'm well aware of what and how far a low power shortwave transmission can go.
There is a very good resource you can use online and it's SDR receivers that are controllable from your pc, they are dotted around the globe. One I was told about is Kiwi SDR, which I've used in the past. I can tell you that 100mw can be seen, not necessarily heard many hundreds or even thousands of miles away, a blip on the waterfall can be made out, so beware that you use only a very short antenna that is not cut to the fundamental wavelength or a division of it. In the right conditions I'm certain that the signal level would be strong enough to be heard.
I'm hoping to pass the foundation and intermediate next year as I'm interested in QRP operation, with home built gear.
