WSPR2.0 at 277.2KHz

Good Whisper reception on my K3S at 474.2KHz.   The NB and NR helps a lot.  My QTH is EN-61

NR is not typically used on digital modes.  I don't think you can even turn
it on in DATA mode.

Noise reduction is also available in CW mode.  The LMS algorithm converges on a sinisoidal wave and forms a filter around the signal.  CW or WSPR is pure sinisoidal and the NR works the best with these two modes.  Last night, I was getting QRN and the NR/NB made it more plesent to the ear.   In spite of that, when I turned off NR/NB, WSPR dB levels were about the same.

I forgot to mention that I was using USB mode and the audio was being fed to my PC via the USB port.  The WSPR software was connected to the K3S CODEC.

Has anyone noticed that 277.2 KHz is not in a ham band?

For the 630M experimental band  set your dial to 474.2 USB , Mostxmit on WSPR , However there are some CW and JT9 two-way qso's.I am txing now.

Probably explains calls with an "X" after the digit.  I'd guess they're
experimental licenses, not ham licenses.

Yes, it's not but I was explaining software that can copy data outside the ham Bands.

Re: WSPR2.0 at 474.2KHz

Henceforth , the threads should read "WSPR2.0 at 474.2KHz"  That was my mistake.

Here's a test with NR on and NR off

0328 -29 -1.5   0.475617  0 WI2XSV EN61 23 (NR On)
0334 -27 -1.5   0.475617  0 WI2XSV EN61 23 (NR Off)
0338 -29 -1.6   0.475617  0 WI2XSV EN61 23 (NR Off)
0342 -29 -1.5   0.475617  0 WI2XSV EN61 23 (NR Off)
0346 -31 -1.7   0.475617  0 WI2XSV EN61 23 (NR On)
0350 -31 -1.4   0.475617  0 WI2XSV EN61 23 (NR On)

Not much change.
