 Thanks for posting this Steve - much that has been puzzling me is now clear. 
Remote SDRs, bizarre DXCC "entities", lists, skeds, FT8 etc are why I stopped 
pursuing awards a long long time ago. But to each his merry own...73

 I have been "sitting" on this for a few weeks wondering if I should share this

I know I would. 

If you have worked Kanti, VU2GSM recently on the low bands...40, 80 or 160 you 
should be aware that he was most likely RX using a NA webSDR. The links below 
are PDF copies of email correspondence with Kanti confirming that this is 
routine for him.The emails are between both VE5UA, myself and VU2GSM. (Please 
read the email threads from the "bottom up" to be chronological.)

To be clear, I do not judge Kanti for his desire to augment his rx, and do not 
think it is wrong. If he chooses to use Ham radio this way that is his choice. 
However, I myself do not wish to include a "half" QSO toward my own (personal) 
DXCC count, and perhaps others will feel the same hence this email. I also 
don't judge others that are good with such webSDR QSOs since each has his own 
goals and objectives.

Here is some background. I have been working VU2GSM frequently and with ease on 
40m in the morning and evening. He would respond almost immediately to my calls 
which seemed odd. More typical is Rakash VU2RAK who has a great signal but 
usually can't copy me, though we have QSOd a few times when conditions are 
While at a local ham lunch, I mentioned this, and Don VE6JY said that Kanti is 
often logged into his webSDR. The following week I copied VU2GSM on 80m in the 
evening with very light copy with my 2el Yagi and 1000' beverage (diversity rx 
with K3). He answered immediately and we had a QSO. I was suspicious. I emailed 
Don VE6JY and he confirmed that at that time Kanti was indeed logged into his 
I deleted the QSO from my log.
This then precipitated the e-mail correspondence which I share on the attached 

There is little doubt this is going on all the time, and we will never know. We 
can't undo the technology that makes webSDR possible.
There are those who who feel that this destroys the “integrity” of the DXCC. 
However, not everyone cares about DXCC.
Kanti is not a villan. He is doing nothing wrong. He is not “cheating”. In his 
email correspondence he is very open and transparent and makes it clear he 
doesn't chase DXCC, and could care less about it. Why should he?
From Kanti's perspective, using a webSDR enhances his enjoyment of the hobby 
living in RFI polluted Bangalore. For others, a "half-VU" QSO is better than 
none and they are happy. 

Like others, I spend a great deal of effort optimizing both rx and tx and 
someday when I do make the QSO with VU on 80 and hopefully 160, it will be a 
true two-way contact. The “buzz” for me is not getting the country counter in 
the log, its about knowing that my station made the contact via radio….both 
ways…all the way.

The purpose of this email is simply to inform those who have worked Kanti 
recently that it is possible/likely that your TX signal was not actually heard 
in VU.
