What Is Possible?

This is the interesting question and perhaps the whole point of trying.

It is known that on 70mhz there are various and variable modes of propagation. Wspr requires a couple of minutes of a relatively stable path (one minute might produce a spot). This is a relatively long period of time and signals are subject to various forms of distortion (doppler, aircraft scatter etc.)

It would seem logical that spots could be made across the Atlantic.  This would require as a minimum the following:

1) Someone to spot.
2) Someone transmitting.
3) Conditions which were favourable - easy to write!

As more people try I expect distances will improve. My personal best is just over 1000 miles. Very poor by HF standards. Yet somehow much more satisfying.

My personal best - SO FAR!
