Most times I have no issues with QRP, but we all know that in many built-up areas noise can be an increasing problem. Over the years we have more gadgets in our homes which can produce RFI. Over time this is likely to get worse.
Weak signals can sometimes be masked by this noise, meaning QRP signals would be harder to spot. It will be interesting to see if QRP operation gets more difficult in the years ahead.
With narrow modes like FT8 (50Hz wide only) and WSPR (6Hz wide needed) this can be less of a problem as we can avoid noise on certain frequencies. Often man-made noise can drift.
Often people are surprised how low the noise floor can be when out /P.
