Hi Ed,
I just put my QRSS kit from Hans Summers on the air a couple of days ago and would appreciate hearing of any "sightings" of my signal.Great job on finishing the kit and getting it on air. Don't forget Steve G0XAR! He and I produced this kit collaboratively and equally! At Dayton I was just the smiley face of QRSS Labs kit sales :-D What are the "various online grabbers" referenced in the QRSS Beacon Kit? Are these people, websites, software...?Websites. People who set up their computer and an Argo screen, and hook it up to a website so that what their receiver/Argo sees is updated to a web page every few minutes. There is a QRSS Grabber compendium site at . I don't know if this has links to ALL the grabbers around, but I think it is fairly comprehensive. It allows you to instantly shrunken versions fo the screens, and if you want to see any in detail, follow the link to the grabber website. Not all the grabbers are online all the time. Nice! I see you! Very clear, right now as of 12:00 GMT (13:00 BST here in London, 08:00 EST) I see your signal on the grabber of W1BW at . Your signal looks to be on 10,140,029 / 135 as you predicted. Your FSK is about 6Hz which is marginally on the wide side, you might want to trim that "gimmick" capacitor slightly to get it down to 4 or 5Hz. But no big deal. Just in case the path to W1BW isn't still there when you read this, I took a copy of the current image and stored it on the group photos, see: . It seemed to get shrunk a bit in the Yahoo-isation process. But if you want, I can send it to you direct via email. Bruce W1BW is in Concord, MA (FN42HL). According to my calculations, that's 849 miles from your location. Congratulations! Conditions seem not too great on 30m at the moment. QRSS is all about patience too ;-) But certainly this little beacon kit is well capable of worldwide results. Check out my pages: (Caribbean holiday) (Turkey holiday) and look at the map of receiving stations etc. All of that was with this exact same circuit, which later became the kit (without modifications from my original). I used a basic wire dipole antenna, with balun at the centre and 5m of RG58 coax direct to the beacon output. No attempts at tuning the antenna e.g. trimming bits of wire off it until it resonated perfectly. None of that. Just my whole low-tech approach to radio! 0.000073 de Hans G0UPL |

Still seeing you on the W1BW grabber. I put a few more shots in for you. I see AA6DY above you at 10,140,061 / 65 too. If I'm not mistaken, he's another of the kits. I see you on the W4HBK grabber too, though I don't much like his colour scheme right now . W4HBK is in Florida, distance 790 miles to you. So your sigs are getting out! 0.000073 de Hans G0UPL |

Thanks for the email, and for answering my question about the "grabbers". I attached an inside, and outside photo of my beacon. Thanks again (to you and Steve) for making the kits available. 73, ed - k9ew On Fri, Jun 4, 2010 at 7:24 AM, hanssummers2000 <hans.summers@...> wrote:

Interesting, I got the pictures when Ed posted his reply. Blue case, LED, what is that little board off to the right inside with the wires to the beacon board?

That extra board is the 5V regulator, held in place with hot-melt glue. Thanks for the note. 73, ed - k9ew On Sat, Jun 5, 2010 at 7:53 AM, WE0H.Mike <we0h.mike@...> wrote:

Sorry, I forgot about Yahoo. I just posted the pictures in the file you created with my callsign. Thanks - ed, k9ew On Sat, Jun 5, 2010 at 3:50 AM, hanssummers2000 <hans.summers@...> wrote:

Looks very nice Ed. Wonder why I got the pictures as an attachment and Hans didn't? Yahoo had to pass the attachment thru for me to get it.

Hi Mike
Looks very nice Ed. Wonder why I got the pictures as an attachment andProbably you chose the individual emails delivery option. I have no emails, and I read the group on the web interface, . I think anyone who reads on the web, or who chose the daily digest delivery option, doesn't get phpto attachments. 73 Hans G0UPL Http://www.hanssummers.com |

Ah, that is the reason. I subscribe to a lot of Yahoo Groups but read all of them in my email client rather than online.

BTW, going to wind the toroids for my 30m kit tonight and it'll be done then. The rest of the board is soldered and clean now. Also have to build a low power wattmeter so I can have a reasonable measurement of the power output. Mike WE0H Hans wrote: Hi Mike |

Hi Mike
BTW, going to wind the toroids for my 30m kit tonight and it'll be doneGood luck. Don't forget: the wire thickness is a bit too thick and so winding 35 turns on the inductor that is in series with the crystal is a bit difficult. In my build of the kit, I wound only 27 turns and it still worked perfectly so don't worry too much about it, that inductor is non-critical. If you have a 50-ohm dummy load (two 1/4-watt 100-ohm resistors in parallel would do fine) and can view the waveform across it on an oscilloscope, you will find you can measure these low output powers very accurately. 6.3V peak-to-peak corresponds to 99mW. 0.000073 de Hans G0UPL Http://www.hanssummers.com/qrsskit |

Speaking of winding the toroids... I found that the finished toroid matched the holes in the pc board best when I wound the toroids like this: -? Hold the toroid so that the two sides (the "flat" sides of the toroid) are parallel to the floor. -? Start winding the wire by inserting it Down into the hole from the top of the toroid, leaving an inch or so of wire sticking up.? (This is your first turn.) -? Continue adding turns by winding in a counter-clockwise direction to get the desired number of turns. So the winding rule for these toroids is Down / Counter-clockwise. There is probably an industry standard for designating this, but I have never seen it. Have fun! 73, ed - k9ew This will give you the best fit of the finished toroid on the pc board.
