RE: LF: 472 QRSS

Hi, Wolf, Tom, Dave,

 

good signals from all of you, with Tom being the strongest one (S9++). But 1200W RF explains a lot ;-)

Wolf was a stable S9 and Dave on average S7 (down to S3 and peaking S9).

I was running a mere 50W RF. As the 48V PSU is on the workbench I had to use a spare 20V PSU (@ 3A).

But based on the signals even 10 W would have done the job in CW and 1 W in QRSS3.

QRN levels were very low tonight, that helps a lot!

 

73, Rik  ON7YD - OR7T

Hi Tom and Dave,

Thanks also Tom, you were 599 here as usual ;-)
Now it will be interesting how Dave's signal in WSPR will compare against the nice audible copy.
Rick OR7T was also nicely readable here despite the strong italian beacon, half a dozen Hz away.

73 and have a nice weekend everyone,
   Wolf DL4YHF / DF0WD

p.s.
   antenna 60 meter wire
   9 to 10 meters above ground
   poor counterpoise (mostly the mains ground during TX)
   120 Watts RF from a switching-mode but linear PA (modulated supply voltage)
   Output transformer wound on ferrite core from old SMPSU using copper foil (!)
       to reduce the pesky leak inductance... works reasonably well.

Btw: Wolf, DL4YHF, you were 589 as usual here in the city.
