Regarding Salvo's complaint, I'm not really surprised. What he's seeing is a natural result of suddenly getting 100-200X as many RTTY spots as were being delivered by RCK Skimmer, 3 KHz at a time. The same techniques as used on CW Skimmer spots, such as CT1BOH's skimquality filters, need to be applied to clean up the spot stream. When in doubt, choose an ARCluster V6 or VE7CC cluster node. And,. of course, continue spreading the gospel about tweaking the radio's frequency a little before you call a clicked spot.

Please note, I'm not criticizing RCK Skimmer in any way. It is the RBN's only source for non-RTTY digital spots, which I'm sure many users appreciate.

For spots, please go to your favorite
ARC V6 or VE7CC DX cluster node.

Think I'm getting a good taste of RTTY Skimmer here. Every time I call CQ on 15 I get about 3 or 4 JA's all zero beat, about S-2 or 3 calling me at the same time. Send 'agn?' and they all call again. Takes 3 or 4 tries to finally get a call out of the mess.

Is there a way to tell it, 'Don't spot me, please?' Think I'll go watch basketball instead. 73

Hi all.
Mario I could agree with you partially. The DL4RCK RTTY was made and worked on field well before any other RTTY Skimmer. Almost two years ago there was a working network of DL4RCK RTTY Skimmer. All those working pretty well. Now I am looking, since almost January, as to make it easy, and the deployment of the VE3NEA Skimmers a lot of busted RTTY calls a lot of multiplier that are not multipliers and a whole plethora of bad call-signs spotted by the newest RTTY Skimmer. By myself my call was spotted as W1AYD several times in between IW1AYD. But also more easy calls that fall under simpler rules are busted since the new and not so bright RTTY Skimmer schema went on. Full stop.
