Topband: Anyone using WSPR or WSPR-X?

[Larry]

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.
