Normally, I run 5 or 10 watts TX output on 160 meters depending on the specifics of the particular run. On 30 meters it's kinda dumb to run more than 5 watts out unless your antenna is a light bulb in the basement. I have on occasion run 100 watts on 160 but if you need to do that because of conditions, you are not going to get any meaningful data anyway. WSPR handles QRN well at least until the RX AGC shuts everything down.

Remember we are using this on 630 meters and have been all summer. You have no idea what QRN is until you play on the real "topband". (which is soon to loose out to 2200 meters!)

Best way to receive WSPR is the same as with all of K1JT's software, turn off ALL DSP functions. Open up the RX bandwidth as far as it will go, 6 kHz is not too much. Use the normal noise blanker with care and discretion. Be very careful about audio levels.

How well does WSPR work when the band is full of static crashes? If so, is
100 watts too much with 20 over 9 QRN? Just trying to learn.

I have it working both RX and TX (5W) on 30 meters right now. :-)
