Hi Paul…
Read the e-mail correspondence from Kanti that I attached to the topband thread.
There is no scepticism or uncertainty about weather he is using webSDR. He
openly admits it. He admits to using it during my 80m QSO. Don VE6JY can see
who the users are on his webSDR and Kanti is very frequently logged in. I
appreciate Kanti's honesty. He does not log into the webSDRs “incognito” to
hide the fact.
Perhaps your QSOs have been direct. Of coarse that is possible. I have worked
him 8 times on 40m over the years, and many of those “early” qso’s were direct
with no SDR. However lately it has become very obvious that he is SDR assisted
when he comes back to callers almost instantly with no difficulty on copy. I
have been to Bangalore. Kanti lives in the heart of the city. You can be sure
RX is pretty tough on the low-bands.
