      Hi guys here is the scoop:
      I believe I have fixed the image problem with the K2DB skimmer, I replaced the computer with a newer higher speed processor and 8 GB of ram added a 192K new sound card and it has been running for a short time without spotting any images.
      I had a phone conversation with Pete N4ZR yesterday and he informed me that there is a technical group which is trying to find the source of the problem with Softrock receivers, Pete asked me if I could go back to the old sound card set up and record the I/Q settings for about 15 minutes.
      I agreed to do that sometime over the weekend. I am really busy this weekend so I cannot say exactly when I will do it. So here is the plan for the K2DB skimmer:
      I will leave the skimmer on as it is right now skimming from 7.000 to 7.150 on the new computer and new sound card. Sometime over the weekend I will shut down the skimmer and retrofit it back to when it was spotting images. (Even if I have to use the old original computer). I will record the I/Q settings as requested by Pete for approximately 15 minutes. At the end of the 15 minute recording I will revert back to the new setup.
      If at any time during the weekend, you notice that K2DB is spotting images, please do not hesitate to send me a text message at: 585-314-8665 or if it is more convenient call me at that number. I always have a laptop computer and Internet access available wherever I am. I can log in to the skimmer computer remotely and shut it down if need be. If it is spotting images during the 15 minute testing period, I will continue to let it run and shut it down after the recording.
      I hope this is acceptable to you guys, and I ask you to please forward this note to any others who may be contesting this week-end.
      Have a great week-end and hopefully we have it all fixed up.
      Now if you guys were not so loud, this would not be a problem ? ☺
      The W2RDX and K2NNY skimmers both seem to be OK, but if they also spot any images, LET ME KNOW !! I can shut them down remotely also.

      Hi Paul - I have a somewhat strange favor to ask. Have you fixed your Skimmer RX yet? If not, would you be willing to make a recording this weekend of about 15 minutes of heavy activity. There are several contests on, including CQMM and the YU DX test, so the bands should be busy. What we need is a recording or two with lots of images, in which the images are producing spots along with spots of the real frequency. Can do?
