Hello and Happy New Year

I'm in the Canadian Arctic,  EP99,  Igloolik Island,  NA-174.  Foxe Basin.  I'll be here for a couple more weeks.

Have been trying to work PSK31 qrp with 2watts using a Small Wonders 20m rig into a folded dipole.  For a few hours at mid day I am seeing many tracings on DigiPan, a lot of them decode very well.  Most of the PSK31 tracings have a "saw tooth" edge to the pattern on the waterfall.  Is this auroral effect on the signal?  Sometimes I see transient bursts where there are hundreds of signals on the waterfall.

After several hours of calling CQ or responding to other's calls no one is answering me.  I wonder if aurora is wiping out my signal?  Igloolik Is is about 69deg north Lat, so likely beneath the auroral ring.

Will I need more power to punch out of this QTH with a signal that can be heard?

Thanks for reading, cheers
David

PSK31 is not very tolerant of distortion. It's pretty common for signal going over the poles to be strong with zero copy. The only fix I know of is to use a different mode. RTTY would probably work better.

I am considering an FT-857D for other modes while in the north.    Grin    Did contact TS2MSN today though, so a success.
