QRP on 10 es 6 m works well because of an= tenna=20 dimentions and ERP  but is a different ball game on LF where= high=20 power is needed to generate a sensible ERP to get beyond the back= yard.=20
Activity this past two days on 10 and 6 m is&n= bsp;non stop=20 in QSO mode  with some vy strong sigals from around EU and beyond= on both=20 CW and SSB. Cannot say I heard much Data. There is the odd Country Bea= con in CW=20 mode but the band is not swamped with individual beacons and pse QSL= via Email=20 freaks.

It must have been fun when CW activity on= 136/500kHz=20 was high.  However, lack of CW activity does not mean lack of= activity=20 per se. Most nights (and some days) I see QRSS or WSPR activi= ty on=20 these bands.

I agree that spreadi= ng=20 activity too thinly can be an issue: if a few of us are on WSPR, oth= ers on=20 QRSS and others on CW, and all at odd times, then the chances of=20 contacts/reports are reduced.
