[RTTY] Getting spotted by RTTY skimmers

[Michael Adams]

There are notes in the second section of http://wz7i.com/cw-skimmer/rtty-skimmer.html

The primary trick is to leave trailing whitespace at the end of the over.   I used "TEST N1EN N1EN CQ " («note the space) and "TU N1EN CQ " («again, the space) and had almost no problems getting picked up.

I did get spotted multiple times while S&Ping, but I think that was a function of being fast on the draw, so that the skimmers could likely have seen " CQ KA0XTT KA0XTT CQ N1EN N1EN N1EN "   A few times, the S&P spots even came through tagged as "skimqsy" or "skimvalid" in the CT1BOH logic.

I apparently need to learn patience.  :)

I do think that the smaller number of RTTY skimmers online, and the challenges of decoding RTTY vs. CW probably contribute to the reduced likelihood of getting spotted by a RTTY skimmer versus a CW skimmer, especially on 80.

This may seem like a silly question, but I will ask it anyway: how does one get spotted by the RTTY skimmers? Is there a "trick" to it?
I am asking because upon reviewing skimmer data for CQ WW RTTY on 80m I realized I was spotted only twice. No, I don't have a farm of antennas, but have a decently performing inv-V with an apex at 90'. Running 1500W.
Just for kicks, I switched to CW and the call sign I used got spotted by a dozen or so CW skimmers with SNR between 20 and 40 db. So my signal is loud enough.  Then I started digging even further and noticed that the stations that were calling me got spotted, but I did not.
I tried different permutations during the contest: CQ call call CQ, TEST call call CQ, etc. None of them made any difference.
Any thoughts?
