Hi,
the contest just ended and I captured very little QRP activities. Fortunately the Marconi Contest was on as well and the QCX on a GP abt 10 m up did very well on 20 m.?
88 QSO's and 26 countries including W, Ja, PY and VK. Nothing to complain about that I believe. My CW ist still a bit rusty and the decoder was a great help for these super QRQ guys. Its funny, the decoder seems to read preferrably QRQ.?

I think you're best off charging cells independently.? You can try building something like this.
I built one, only to realize the boards I got are defective and don't actual have any output.? Thanks, China!??
I'm using a buck converter to take 12V from my bench power supply (or from the car) and bump than down to 5V.? The same could probably be done with a 12V solar panel.? I'd like to try a smaller 5V panel to skip the buck converter step.

Hi Folks,
?
I¡¯m nearly finished building a QCX
transceiver and would like to put it into a case with a clear
acrylic top.? I saw one case like that in the builder¡¯s
gallery, but no info on what it was or where to get it.?
Anyone know of a case with clear acrylic top that fits the
QCX?? I guess I could make one out of 1/8 acrylic, but that¡¯s
a lot of work cutting/smoothing/polishing/gluing, etc.

Re: Shipping time to the US
Oh Hans, no problem! They probably mistakenly put it on a crippled camel on the "silk road"! Now that USPS has it, it's probably coming from New York City to Dallas by Pony Express!? :-))

Hi Roy
Of the 41 people who have informed us of package arrival since the relocation, the average shipping time to US is 13 days. But as always, there is plenty of variation in the international post services.?
73 Hans G0UPL
Looks like you can expect about 3 weeks or more for delivery to the US. It took 2 weeks to get to US customs and so I'm expecting at least another week before I get it via USPS! I'll update when I finally get it.

Hi Greg...
Yes, QRP Labs ships from where I am. Which was Tokyo until June 2016. And indeed for nearly 2 more years after I left, since the part-time helpers I had there were doing a good job and were keen to continue. QCX changed all that since the girls just couldn't keep up with the increased order volume. Hence it became to reunite myself with the shipping operations to get things back under control and create a more sustainable and scalable operation.

A considerable achievement, Hans. Congratulations. On 6 Jul 2018, at 14:41, Hans Summers <hans.summers@...> wrote:

They actually DID understand about Morse code and telegraphy, I suppose Morse telegraphy is an important part of the post office history. It is. Before the introduction of telex, the Service used landline telegraphy. One member of a parallel branch of my family was a Landline Telegrapher In the 1920s. 73 John F5VLF and G3PAI

How cool is that! I just ordered a 20M QCX and look forward to building it. I'll order a 17M version when the stamps arrive :)

I just went to the post office this morning and received my qrp labs clock kit. Interesting that this was shipped from Mugla, Turkey.? Kind of curious about the qrp lab's distribution, I thought kits were coming merely out of Japan, as I believe my QCX kit originated there.

Re: most popular band ordered
Hello Hans,
Friday, July 6, 2018
The forum will need a philatelist section now ;)
I see Hans is visiting London, someone saw him looking for a little
berth to moor up yesterday <LOL>
Well done Hans, good to see QRP Labs doing so well after all the hard
work you put in!

Re: U3S & OLG1 new version drifting in Altitude
Hi every one and thank you for this information, as this is the first OLG1 GPS i have made and used i was not sure of the accuracy.
This is interesting? as i was not sure what to expect.
My GPS is hanging in mid about a foot of the work bench above the U3S i have a 3 meter shielded lead attached so i can move it if needed for better accuracy.
I would be most interested in the software you are using.
If you can please advise which would be best software this would be most helpful as i would like to understand more of what it is actually telling me.
Kind Regards

Re: U3S & OLG1 new version drifting in Altitude
Your fan was acting as a reflector and causing doppler shift of the received GPS signal.? ;) Pretty cool, eh?
On Thu, Jul 5, 2018 at 9:48 PM, Arv Evans <arvid.evans@...> wrote: Stuart Vk5ade
When you first turn on a GPS receiver it has to download a lot of information (called
ephemeris data) from the satellites.? Since this is sent in slow bursts between other
satellite information, it can take over an hour in some of the older GPS chipsets to
complete.? Newer GPS chips are faster, but there is some speed limitation due to
limited transmission rate of this secondary information from the satellites.?
Once the ephemeris data is complete and processed most of the GPS measurements
should stabilize.? I just pulled up the altitude, speed, and heading page on my local
GPS unit.? It took 12 seconds to give any display, and this is with ephemeris data already
loaded.? Speed is moving back and forth between "0" and 1 MPH, although the antenna is
lying here motionless on my desk.? Heading shows 13-degrees, but this is possibly an
artifact of atmospherics because the unit is not moving.? Altitude was changing between
2768 and 2714 feet but when I sat the antenna in the window this stabilized at between
2768 and 2765 feet.?
Hmmm...when I turned off the fan next to the window the speed immediately dropped to
zero and stayed there.? Heading is still 13 degrees, and altitude has stabilized to 2645 feet.
It is possible to use software to average GPS readings to something that may be more
accurate in the long term.? DGPS, or Differential GPS, does something similar by using a
known exact location reference and comparing that with that received from the GPS receiver.
With both received and known locations it is possible to calculate correction factor and
arrive at location measurements that are very accurate.? Surveyors and construction
architects usually use GPS and DGPS correction for height and position measurements.?

It is working ok but i have noticed that there is quiet a drift in Altitude within a 2 hour time period.
As my QTH is only a couple of hundred meters from the water, South Coast of South Australia.
I am noticing that it has quiet a large drift from -4.5m - 40m above sea level.
Just a bit concerned that this is normal for this amount of drift or is there a issue with the components.
