A new record – G to ZL on 60m QRSS

Toward the end of March I ran WSPR and QRSS on the 60m band for a couple of weeks.  I did some experiments on 60m nearly three years ago which gave good results and I was keen to improve that.

I posted on the new Knights QRSS list to announce that I would be active on 60m in the hope that some of the grabbers around the world would switch to 5MHz to listen for my signal and I was very pleased that a number of people happily switched over for a while.  It’s an unusual band because there aren’t that many countries that have a 60m allocation and they don’t always match up around the world.  Of course, anyone is free to receive on the band so that helps.

I was very pleased to receive the following reports.

G6NHU to ON4CDJ on 60m - 208km

G6NHU to ON4CDJ on 60m – 208 km

G6NHU to G3VYZ on 60m - 400km

G6NHU to G3VYZ on 60m – 400 km

G6NHU to VE1VDM on 60m - 4,637km

G6NHU to VE1VDM on 60m – 4,637 km

G6NHU to W4HBK on 60m - 7,293km

G6NHU to W4HBK on 60m – 7,293 km

All very good but no improvement over the tests we did before.  There’s one more though.

G6NHU to ZL2IK on 60m - 18,130km

This is a stacked image and is still quite weak so let’s zoom in a bit.

Here’s a capture from Pete’s eight hour grabber showing my received signal repeating itself around twelve times between 06:00z and 08:00z on 23rd March 2017.

As far as I’m aware, this is the first time that QRSS signals have been successfully transmitted from G to ZL. I’m using my Hans Summers U3S transmitter with around 250mW output into a random length doublet, just 30ft AGL at the east end, sloping down to 20ft AGL at the west end.  Pete, ZL2IK is using an Icom IC-R75 communications receiver locked to a GPSDO frequency standard (no drift) and a combined 80/40m dipole fed through an ATU to match it to 60m.
