Re: UQRSS with WSPR (without/with GPS) and FSKCW3 (with GPS) on 30 M

Hello all, In my former message I mentioned using WSPR without and with GPS. I had first used WSPR without any connection to a GPS unit: (later on I only connected GPS in mode WSPR to see if the QTH locator and time were right, but did not test WSPR GPS further then.....) This use, without connection to a GPS unit worked well both for QRSS/FSKCW and WSPR, and the adjusting of the FSK shift (Fskadj) in Testmode was also good for running WSPR: First C-8 had to be tuned to the QRG which was set in the Menu of UQRSS. After that the FSKadjust had to be right using a shift FSK of 4 (or 5 Hz). Then choose Mode Test or FSKCW with a low speed, say 009, and Frame 00 and Start 00. After a lot of adjusting the FSKadj was found, let us say 00,800. For WSPR the Frame had to be set then on 10 and Start on 0,2,4,6,or 8. I choose Start 02. After setting the Time using a pretty precise Clock, all was running well in WSPR and also the other modes QRSS, FSKCW. BUT: After I connected with these adjustments above, the GPS unit ( EM-406A with 10 K pull-up resistors from the +5 Volt to both the Data and 1 PSS line), and after powering up the UQRSS and the connected GPS unit, some strange things happened: (BTW: Use the Start in the menu a few times after powering up the QRSS with the connected GPS !, so that the Time on the UQRSS display is in sync on the precise Second with a DCF77 Clock or precise Internet Time....) The QRG dropped now on WSPR TX not only about 25 Hz ( in my case from 10.140190 to 10.140.165) but also the Shift had gone up ! This was now for WSPR about 7.1 Hz. ( had to be around 5.9 Hz). In the Menu the QRG was still 10.140.190....and FSKadj still 00.800... Of course no detection of my to wide WSPR signals on the WSPRnet.org. So now I tried first to set QRG in the Menu to the new QRG 10.140.165 (no change of C8!) to see if the Shift was back again around 5.9 Hz. But on TX now the "real" TX QRG dropped even further down hi. This was not the way! So I put the QRG in the Menu back to 10.140.190 and tuned the C-8 up to 10.140.190. Now even more strange things happened. On TX the QRG shifted regulary about 100 Hz up and down like a warning signal hi and of course no good WSPR was being send. So I put with C8 the QRG back on 10140.165 ( in the Menu still 10.140.190) and adjusted the FSKadj to a smaller value (from 00.800 to 00.730). This adjusting took a lot of time but finally I got on WSPR the 5.9 Hz using Argo Speed 10. Why not use Test for shift adjustment with the connected GPS and Menu GPS ON? Aha: In Test mode with te connected and running GPS unit the Shift is a bit more then in mode WSPR … so best is to adjust FSKadj in mode WSPR. Use Argo Speed 10 and aim at the middle of each 2 most outside WSPR tones to see if it is around 5.9 Hz. Yes once you know the trick it is not difficult anymore. Hi. BTW: I tried another GPS unit ( Jupiter T) but the result was about the same. Changed both IC1 and IC2 the result was the same. Had ordered a few more...for other bands. Hope it helps others a bit. It was nice doing it and with very good results. 73 Paul, pa0ocd Nice result now with WSPR: VK4TMH at 15690 KM with 0.2 Watt on the Indoor Magnetic Loop ?2012-09-05 16:12? ?PA0OCD? ?10.140169? ?-25? ?-1? ?JO22li? ?+23? ?0.200? ?VK4TMH? ?QG56fj? ?15690? ?9749 |

My Ultimate order
Gary Kohtala
Steve,
?
I think I may have under payed for postage to my United States address. I do hope that my order went out by air, despite my oversight. I remember choosing UK First Class, not knowing what I? was doing. Your posting to the group made it clear that I made an error when selecting the shipping method. Please calculate the difference owed and generate a PayPal invoice. I will promptly pay the difference.?

Thank you very much.

G0UPL beacon kits - Order processing and shipping - please ignore if you are not a customer.
Stephen Farthing
Hi everyone,
Just a quick note to let you know what to expect when you place an order with us for a basic model beacon or an Ultimate one or anything from the shop. I pack orders once a week, generally on a Sunday morning, and ship them via the local post office on a Monday. This means that if you order something on a Monday it isn't going to get sent until the following Monday. We use airmail for shipping outside the UK and 1st class post for UK post. To keep costs low we don't use a tracking service. This means as soon as I give the parcel to the Post Office I have no way of knowing where it is until it arrives with you. The software we use for the shop sends you an email when I have packed your order saying it has been shipped. So you should know that it's on it's way. Please make sure that your address is correct and, if you are ordering a basic beacon kit, the data you want me to program into the keyer chip. Sometimes things take a while to arrive. It is not unusual for a parcel to take 3 weeks to the USA, parts of Australia and NZ. This is outside my control. It is, however, unusual for a parcel to be lost. I think we have lost 2 parcels in over 700. The record for lateness is held by a parcel sent to the USA, ironically it arrived in the same post as the replacement parcel. We don't insure the parcels, we rely on the UK Post Office to refund the money on lost packages. They only consider the package lost after three months. Practically speaking they never pay up, they can always find an excuse not to. Sometimes I make a mistake with an order. If you EMail me I'll rectify it ASAP at no cost to you. We ONLY take payment by PAYPAL in POUNDS , or, by special arrangement, in Euro or Pounds stirling NOTES only or Hungarian Forint. If you want to pay with a credit cars you can do this via PAYPAL Sometimes I sell at Hamfests, and I'll post advanced warning of this on the newsgroups. Mostly I go to Hamfests in the Netherlands and Pordenone in Italy. If you have any support issues please address them to QRPLabs@... not the Knightqrss reflector because it is tedious to clog the latter up with posts which the majority of subscribers do not want to read. Thanks from buying from us and we hope you enjoy the kits Steve G0XAR - the man that packs the kits and puts the in the post! |

UQRSS with WSPR (without/with GPS) and FSKCW3 (with GPS) on 30 M
"paulwijnand"
Hello all,
Build the UQRSS for 30 M a few days back and started without the use of GPS. Nice kit to build! Thanks QRP-kit team! Changed the capacitors C4 for 22 pF N750 and C5 for 15 pF N750. Looks it stays better on QRG using N750 then N0. Have to experiment with C3 with a N750, see what it brings in Temperature compensation. But that is a long process, will take a few weeks... Anway I started with WSPR, in the menu put in the Time (hours and minutes) and hit the button there when at a DFCC clock the seconds jumped from 59 seconds to 00. It seems that in this way the DT is nor far off in WSPR, about 1 second. Results were fabulous running 0.2 Watt on my Indoor magnetic loop of 1.5 by 1.5 meter. 2012-08-28 06:52 PA0OCD 10.140179 -23 -1 JO22li +23 0.200 KC9NBV EM69oe 6775 4210 . So a 6775 km is not bad hi. The time without use of GPS stayed very precise! during a day or so. But have seen in the messages here, that it will stay longer precise. I monitored WSPR on a second notebook and a precise homebuild transceiver locked on a double oven OCXO 10 Mhz standard. After that I used GPS to see what that brings. I have a old GPS Jupiter T Firmware V1.80 and used 10 K pull up resistors from the +5 volt from the Data and 1 PPS line. This one uses an extern antenna and has for both the module and antenna + 5 volt powersupply via the UQRSS. Without the use of these pull-up resistors the UQRSS goes wild in adjusting the QRG hi The other GPS is an EM-406A also using 10 K pullpup resistors and has a internal antenna. Nice little module and with a very high sensitivity. Also +5 volt power supply. Used them both. For WSPR it is with firmware UQRSS 1.04 nice to see the right QTH locator and precise timing. After that I put on FSKCW3 with Frame 10 and Start 1 at 10.140.080 with a shift of about 6 Hz. In the menu GPS ON. Let it run for a few days and could see my signal on the grabber of Bill W4HBK (Tks Bill!), also a nice distance of about 7522 km...No stacking of the pictures needed yet. The GPS adjustment was nice to see and was soon withing 1 Hz. The timing was also good. The first Character was send after a 3-5 seconds (about) after the startminute (Start 1). BUT: A: After a few hours, the display showed a not changing time of 12.28.36 or 05.28.36 or 08.28.36..... The character being send were not showed any more... This was the case with both GPS modules. The GPS adjustment an timing were still ok! and the characters were still being send. (hi) After starting the FSKCW3 mode 2 times , not one time!, all was running well and the time showed ok in the pause when the message had been send (PA0OCD JO22) and the start of the minute 1. (Frame 10 Start 1). This time it stopped at 11.18.36 (put it on at 10.24 utc)... B: Then I removed the powersupply and put it on after a while. The FSKCW 3 started automatically BUT not at the right time and the display was also not showing the right time. After starting (with the powersupply on) the FSKCW3 2 times all was well again. Perhaps I had to wait a bit longer then 10 minutes to see if the Time was right again by itself... I still have to test the other modes. That was my experience up to now. Will build the other UQRSS modules, but perhaps with 1 display, not sure if I can switch the display between the other modules while they are running... 73 Paul, PA0OCD |

Re: UQRSS 30m
Tony Volpe
Yes David - propagation has been dying off around 2300hrs ?but did you notice how the skip went long in the middle of the night? All the 'local's at 500km 800km vanished and then for me, the Americans came in at 5000km 6000km around 0300hrs - well before the greyline propagation would hit my qth. As that occurred, at about 0700 gmt on about three mornings of late, I have been spotted 16000 km away in vk, mostly by vk2ddi. Then at around 0800, the locals pop back up again.
Another thing to note is that the Solar Flux has been steadily rising. Last week it was around 92 (pretty quiet band about 1 or 2 spots per tx cycle) and this morning it is at 132. This kind of rise leads always to many more spots per transmission cycle. The last 24 hours I'm on 729 spots. Bear in mind I am generating 530 milliwatts, though I have no idea how much of that is getting through the atu into my non resonant antenna.
Xray flux is also on the rise and that probably increases absorbtion on 30. And you are right - the kit is great fun, and I am eagerly awaiting the new one which I will put on 20meters. I have already penned down a crystal to the right locality. Hopefully it will be stable enough to operate wspr. We shall see

UQRSS 30m
"David Barber"
Powered up and on air now for six days continuously.
One change made after 76hrs of operation to the transmission cycle and the "Power" data was updated to show actual output power. Has been functioning impeccably with no appreciable drift. Still just lashed up on the operating desk. It has been interesting to note the virtual cut-off of propagation between approximately 23.00UTC and 05.00UTC every day, also recorded by spots of Tony's (BZB), G4JVF and G4SFS signals. Great kit, great fun. Thanks. David G8OQW *** |

Ultimate QRSS kit, pads for coils
"newarroja"
Good morning,
I'm almost done assembling an Ultimate QRSS kit for 40m and noticed that the assigned holes to insert the coils do not have solder pads. Is this normal or should I proceed and do a little scrapping before inserting and soldering the coils? Thank you, Paulo, CT2IWW |

Re: QRSS3 beacon on 10139.957
"TONY_VOLPE"
Rather than build a special oscillator circuit, I am planning to build the new UQRSS kit with a crystal socket and use that to do the penning adjustments. Since in TEST mode the kit works as a frequency counter showing the free running oscillation if you connect a GPS, I will use it to monitor progress..... That's the plan, anyway. We'll see how it goes when I get down to it. Should be fun, and a learning experience. I might also leave out c5 unless I need it. Since it is in parallel with the trimmer, which I think may now be of a higher value from something Steve said, I will hold off on soldering in the cap.

Philip's photo of his pluggable development kit has also given me some ideas. Breadboard could be another way forward. I'll think about it and see what I can do best. Bzb --- In QRPLabs@..., Hans Summers <hans.summers@...> wrote:

Ultimate QRSS kits back in stock, and 160m version
Hans Summers
Hi all,?
Steve and I have components for another run of the "Ultimate QRSS" kit, please see?
Also we have a 160m version now available too (1.832MHz crystal).? Steve is testing a 20m version in the next few days.? Note that henceforth Steve will always ship kits and components on Mondays, so he has a routine and time to pack everything on the weekends.

Re: QRSS3 beacon on 10139.957
"TONY_VOLPE"
Forty hours without intervention is pretty good David. I find mine is prone to go awry when the ambient temperature changes a lot. I think this is day three of more or less perfect operation for mine without any intervention. This is because the temperature in the walk in cupboard where it 'lives' has been a steady 19 - 20 degrees. If the sun shines on it through the window, the frequency moves too far for the micro-controller to keep order and the modulation flips. It flips either into a very narrow fsk deviation, or a ludicrously wide one. I have seen wspr tones flip in a sort of two tone, ultra slow rtty with the tones 20htz apart. Whether it goes wide or narrow in these situations depends on whether the oscillator's free running frequency is high or low of the set frequency. Hans has explained it all and I quoted the message elsewhere. It is not a fault; the software and hardware are behaving exactly as you would expect in the situation where the oscillator is out of line with the data entered by the operator.

I might write something about my antenna with some drawings. I have experimented with multiband wire antennas here for thirty years and this one is the very best I ever had. What is more it is almost invisible being made out of wire just less than 0.5mm thick. It works like magic and hasn't broken in a whole year, although the darned 300 ohm ribbon did break off the feed point in a gale, but the loop was undamaged. People think a full wave forty meter loop must be massive, but it isn't if you take it over your house as well as garden. If it was square, you'd only need 4, 35 foot lengths. Mine is longer on two sides and about as wide as the semi I live in, give or take a couple of feet. Thin wire like this really is invisible and I have to actively search it out to see it against the sky. --- In QRPLabs@..., "David Barber" <david.barber@...> wrote:

problems. Should really update the power setting to show the real output power but don't want to take it off line. Tony - Excellent result with the VK and W spots, still hoping here but I doubt the antenna is up to that compared with yours. I would certainly endorse your appreciative comments on the kit and would hope to obtain another one for further experiments. David G8OQW *** -----Original Message-----

Well - I bought two crystals for 14.132 for about ?1.80 delivered and I am going to have a go at penning one of them down. It may be a long shot, but in his article on the subject, Hans managed to get a 10 megs crystal down by 150khz. I only need about 40khz, so for a couple of quid, it is worth a try. I know someone with a lot of dremel stuff - fine wheels and such, so I will borrow that and cut the can off as neatly as possible, and have a go with overhead projector pens.

If it doesn't work, I will have learned something, and I can order a custom made one from Quartzlab for ?22. Philip G4JVF has one on order from them. They need a month's lead time to make a one off. It would still be worth it to get on 20 meters. There is a lot of WSPR going on there just now. If you are not releasing a 20 meter version this week, I can adapt whatever you do release by changing the LPF values. Maybe I would need to alter the windings on the PA drain inductance? Do you think so? Perhaps a couple of winds less on there? I don't know, but can fiddle about and see. Tony --- In QRPLabs@..., Stephen Farthing <squirrox@...> wrote:
