Guys, It is really nice for Hans and I to see the results of the hard work you put into getting the kits we produce on the air. It is so encouraging to see you all getting seen on grabbers and getting WSPR spots. And we both learn a good deal from helping you with problems and getting your kits on the air.?

And you and Hans need to know how much we appreciate the fun and challenge the kits have given us. I can't wait to get started on the new one which will be put on 14.0971 MHz.

Meanwhile, it was a good night on 30 meters; four spots of my half watt beacon from VK2DDI and 9 from W1XP. Very pleased indeed. Thanks again BZB --- In QRPLabs@..., Stephen Farthing <squirrox@...> wrote:

Hi Tony,
Thanks for the nice words. You will be pleased to know as soon as i have finished making up the new batch of kits I'll be testing the 20 meter one. But we only have crystals for 14.000,000 Mhz. So the traditional frequency for WSPR will not be attainable.?
Presumably you are getting a crystal custom made? 73s Steve |

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:

I got mine here - he has two pairs left as of now:

I was slightly wrong on the frequency but not by much. Philip ordered a one off from Quartzlab. Tony --- In QRPLabs@..., Stephen Farthing <squirrox@...> 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-----

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:

Steve I don't think you'll be able to pull the crystal that far. I do think Tony will be able to "Pen" it that far. FYI the page Tony refers to is

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:
