10m tropo

Weak signal modes never cease to amaze me. This evening I've been exchanging 5W WSPR reports with G4CUI 173km away near Sheffield on 10m by what I presume is tropo. Running WSPR for hours on end certainly shows unexpected paths popping up from time to time. Even 5W is enough with this mode, and I assume modes like JT65.

If properly exploited by using weak signal modes like JT65 and WSPR 10m could be a great inter-G band even with QRP and small antennas. I wonder who will be the first G station to Work All Britain on 10m JT65 with QRP?

Good point. I'll have to add building a 10m antenna to my list of things to do (currently, building a Theremin). I'm sure it's just that I just wasn't listening, but I don't think I've heard anyone talk about using these weak signal modes on that band before!

Just thought - could you let me know what frequency to listen on? Thanks

Hello Roger, I'm also a big fan of 10m WSPR, hoping to get a cb vert, or maybe a moxon on 10m soon...

Hadn't thought about trying out JT65....

It's really quiet on 10m here in IO71lu, but hopefully the digimodes will help sort out that problem..
