Several members of this forum rightfully objected to my post "doubting" VU2GSM's use of remote RX in QSOs since he had openly admitted to same in his correspondence. Since I view my e-mail in reverse chronological order, I had read Paul's post and responded before seeing the posts by VE6WZ with the links to his correspondence with VU2GSM. I apologize for my hasty response and resultant ambiguity.

Nevertheless, I have worked Kanti a couple of times on each of 30, 40 and 80M. The 30M QSOs took place generally around his SR and early evening here, and I have heard him many times in that time frame on that band. I use a two element quad and either 100 or 200W output on that band, and his reports of my signal, 559, are consistent with those conditions. When I worked him on 80M, I began a correspondence with him. His response to that initial e-mail was "Yes i got you clearly and you were overriding QSB." That sure sounds like he was copying me directly. Further, for some reason when I had QSLed him directly, I had omitted our 80M QSO and had to request a second QSL from him via e-mail. In that exchange there was not the slightest hint of his using remote RX. Subsequently, because he knew I had an Expert 2K amp here, we had several detailed e-mail exchanges to discuss the set-up of his newly acquired 1.3K amp. Again, there was absolutely no hint of using remote RX.

It appears that he does use remote RX at times, but a review of the times and signal reports for all our QSOs strongly support direct, long haul reception.

Again, I apologize for any ambiguity in my previous post.

Like Paul, I seriously doubt that Kanti is using a remote receiver. I have worked him on 30, 40 and 80M and have had occasional correspondence with him regarding his relatively recently acquired Expert 1.3K amp. The signal reports he has given me seem appropriate for the times and band conditions at the time of the QSOs. I'm confident that had he been using a remote RX, it would have come up in our correspondence.

No doubt some ops are using WebSDR on receive, but in this case, I am skeptical of the skepticism. Here's why:

I routinely work VU2GSM on 40m GL-LP in the early morning hours on a 210-degree bearing from FL to VU. He is consistently S9, peaking +10 dB on my Elecraft K3. The remote station I share with N4CC is in Hilliard, FL just east of the St. Mary's River. Our antenna is a full-size 4 el. M2 40m OWA at 140 ft AGL.

On the 210 deg. bearing, the land slopes almost immediately into the river valley. VU2GSM's solid signals aren't an isolated event; he is that strong most of the LP season. VU2GSM cannot be detected on my backyard dipole at my home QTH 30 miles to the south in Jacksonville. The dipole is up 35 ft. AGL. When I say he can't be detected, I mean there's no trace on the dipole whatsoever, not even a blip that rises above the SDR noise floor. That's to be expected on a low dipole if the arriving angle is skimming the horizon.

According to HFTA, the statistical mode from FL to VU is 1 degree above the horizon. The sloping terrain accounts for much of VU2GSM's solid signals into the station. Forget 4-square arrays over good soil, Forget stacked arrays up to 200 ft AGL. Apart from verticals on salt water, nothing else compares with high horizonal antennas into sloping terrain when the statistical mode is 1 degree above the horizon. When VU2GSM is +10/S9 here, I am certain he is hearing me on his dipole and he doesn't need WebSDR.

When I hear other NA stations calling VU2GSM on 40m, he cannot hear many, if not most of them. Of those he picks out, he struggles to copy unless they're from stations with excellent antenna systems - like those in the RHR group. So, if VU2GSM is routinely using WebSDR on 40m receive, his operating habits are not reflective of such claims.

Paul, W9AC

I have been "sitting" on this for a few weeks wondering if I should share this information, but after seeing some spots yesterday for VU2GSM on 160m, I decided that others may appreciate it.
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.)

https://drive.google.com/file/d/15n35-1wHPOdWi2Xib7QAQgxkg-hrOujs/view?usp=sharinghttps://drive.google.com/file/d/15n35-1wHPOdWi2Xib7QAQgxkg-hrOujs/view?usp=sharing <https://drive.google.com/file/d/15n35-1wHPOdWi2Xib7QAQgxkg-hrOujs/view?usp=sharinghttps://drive.google.com/file/d/15n35-1wHPOdWi2Xib7QAQgxkg-hrOujs/view?usp=sharing> https://drive.google.com/file/d/1MdZFLJrwcBs-vHh0PNZc2DSevu3lrwcg/view?usp=sharing <https://drive.google.com/file/d/1MdZFLJrwcBs-vHh0PNZc2DSevu3lrwcg/view?usp=sharing>

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 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.
I deleted the QSO from my log.
This then precipitated the e-mail correspondence which I share on the attached links.

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.
