Topband: VU2GSM webSDR use

Hi Steve,

I believe it is important to make clear when we are using a distant 
WebSDR receiver so we do not mislead others to wrong conclusions about 
propagation conditions nor the performance of their station equipment. I 
do agree there is nothing inherently evil about using WebSDR. One 
primary goal of ham radio is to communicate. You can't work them if you 
can't hear them. But we also draw conclusions about propagation and 
station performance. In the case of "contests" or activities like DXCC 
paper chasing use of far remote receivers could undermine the core of 
the activity. I am not a paper chaser so others must decide that issue.

I have been playing with WebSDR reception and I expect to eventually 
submit some logs that relies on use of those. The log will always 
include the information about what receiver was used and it's location. 
I think that is important information. Others may have different 
motives. I am not a radio legislator and I am not in enforcement.

Do your best to fit your own activities into the 'big picture' and 
practice good citizenship.

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.)

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 exceptional.
> 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 SDR.

> 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.
