Re: v2.02k - Twice the fun, WSPR and QRSS together! (and new feature request)
Hans Summers
Hi Colin?
You are saying an automatic locator, which gets the latitude and longitude from a GPS module, converts them into all those digits, and appends it with an accuracy specified by you?

My v2.02k arrived this morning and is now up & running under test and seems to be working just fine. I was wondering if it would be possible to append an automatic QRA function to the QRSS Message in a future incarnation of the 'k' version? i.e. in my case a Message of 'M0XSD ' would become 'M0XSD QRA IO84GN00SB'. With the menu item being in the range 0 to 10 in even steps, 0 being off (no QRA displayed) up to the maximum of 10 (as shown in my example above). I would find this extremely useful to let people know my exact position (to the accuracy defined) when out portable. 73, Colin M0XSD. --- In QRPLabs@..., "m0xsd@..." <m0xsd@...> wrote:

WSPR Problem Using V2.02a
"John"
¿ªÔÆÌåÓýHi Group,
?
I've installed the new V2.02a chip, but having
problems when using WSPR. The transmission starts OK but at the end of the 2
minute period the RF does not shut down. Has anybody experienced
this?.
?
Hans, I'm using a Navman Jupiter 21 GPS module
(TU21-D450-021).? I rescued 3 from EPIRBs that were considered beyond
economical repair by our marine dept. and destined for the WEEE waste. It works
fine on both the old and new version of the chip, but does need an external
antenna, another one for the GPS compatability list.

I don't have to wait any longer, my v2.02k chip and a couple of LPF filters arrived this morning (26th Jun 3013). Fitted the chip, put in some setting & fired it up & have already heard & decoded myself on 40m WSPR :) Now to see if I can see myself on QRSS. 73, Colin M0XSD. --- In QRPLabs@..., "Colin XSD" <m0xsd@...> wrote:

Re: U2 on 20m kills 30m.
Tony Volpe
That's quite a typical response for a receiver when it has a strong local signal overwhelming its front end and producing intermodulation products. Even though the UQ is qrp or even qqrp, when it is right next to the receiver, t will put a hell of a big signal into the receiver even if it is adequately screened, it will get in through the coax braid and in other ways, even if it doesn't just get in via the receiver antenna. Just the other day, I received a notch filter for my Freeview TV from the 4G people ?to protect my reception from their new transmissions on 800 mhz. My Freeview channels are around 700 to 780 mhz. They must be going to fire up a 4g transmitter near to my location soon. The problem they are trying to counteract is the same one you have seen happening with your UQ beacon. Tony G0BZB |

U2 on 20m kills 30m.
Keith Maton
OK, here's a good one.
I'm running my QRSS grabber on 30m right now and sitting on top of the TS-590 is my U2 kit transmitting WSPR on 20m. When it's transmitting, I totally lose everything on 30m and I get a really strong broadcast station. If I switch the wireless to AM, it's showing +40dB on the LCDometer. Clearly there's some mixing going on there somewhere with a product ending up on my QRSS frequency but I'm not sure exactly what's doing it. It's a shame I've not heard an ident from the broadcast station, it would be nice to know where it's coming from. This is not a complaint, merely an observation. 73 Keith, G6NHU |

Good evening all
?
A quick note about the shipping. Orders are normally shipped the next
business day after they are received. The exceptions are:
?
1) When a huge volume of orders are received suddenly, it can take a while
to clear. An example is the sudden influx of orders from people who wanted
v2.02a or v2.02k chips. In that case the orders are worked through but it took a
week until every order was sent.
?
2) When the kit is out of stock, such as the Ultimate2 - in which case
you'll have been advised on the ordering page of that. The U2 kits are now
pending only on the PCB, which the manufacturer claimed would take a week to
make but in fact took very much longer. The latest date they gave me is tomorrow
(Tuesday 25'th), then they have to be shipped to me; hopefully we are getting
close now.
?
So please be patient in case 1) because as you know, this is a low cost
operation, there are not a whole army of people waiting on orders and ready to
go immediately an order comes in :-)

Hi Frank, I used a separate 3.3v reg to supply pins 4 and 5 directly. no resistors were used anywhere on the gps unit. Pin 6 is pps and pin 2 is txd. Pin 3 is earth.

Best DX on 80 meters

Re: U2 and GPS report (good)

Just received my version 2.02a 20 minutes before heading off to work. Can confirm the unit fired up first time with gps working and calibrating the output. No fuss and no hassle. My gps is the UP501 unit. Well done Hans, you are onto a winner here. I will fire up most probably on 20m wspr tonight when I get back home and monitor the frequency accuracy on my grabber at www.qsl.net/gj7rwt/gj7rwthomepage.html 73's de andy From: "andyfoad@..." .

Hi David,
It's nothing special at all - honest. It's a pure 8ft square loop which is fed at the bottom centre via a suitable matching unit in order to transfer as much power into it as possible ;-) Experience with this stealth antenna for about the last 10 years has shown that just plonking a CLC type T match is the best way to feed it. Capacitor (series), Inductance to deck, the another Capacitor(series). I think the first time I made a QSO on it was on 17m SSB to 3B4CF with just 15 watts. It was nothing more than a wire loop drawing pinned to the bedroom wall :-) I wrote a brief article about it here: Really, it's just a piece of wire... Hope that helps. 73 de Andy --- In QRPLabs@..., "David Atkins" wrote: > > Hi Andy, > > Can you share a bit more info about your loop and its tuning?

Re: U2 and GPS report (good)
Tony Volpe
On randomness and antenna length, I generally try to ensure with loops that they are at least a full wavelength long on the lowest operating frequency. If that is achieved you can tune them on that all higher bands, even though they are non-resonant. Take my current free space forty meter loop, it will work on all the higher bands I've tried it on and is pretty good on 20, but works on 30 to an acceptable level. |

Nice clean signal on 28Mhz.
"andyfoad@..."
Must have been a few oddities in previous tests with the U2 on 28Mhz.
Now that I've moved mine up into the attic, and walked a mile away to do some listening tests using the FT817 the signal is as clean as a whistle ! Gives some hope of the possibility of 50Mhz operation being useable, assuming of course that there's a suitable PA attached to it. I don't think those BS170's are gonna be macho enough ;-) I wonder if the Mitsubishi RD06HHF could do the job ? Rated at 50mw for 6 watts out aT 30Mhz with 12v dc. I see that SDR Kits sells them in the UK. Food for thought for anyone wanting to push the boundaries a bit. 73 de Andy G0FTD |

Re: U2 and GPS report (good)
"andyfoad@..."
Try it and see how it works Tony.
As if often seen, random bits of wire work better on some bands rather than other, depending upon the distances in the doglegs etc etc. Sometimes results are surprisingly good, and others can be disappointing. Suck it and see ;-) 73 de Andy |

Re: U2 and GPS report (good)
Tony Volpe
On the matter off loops, I am thinking of running wspr on two frequencies simultaneously and am planning to make an invisible horizontal loop of fine wire using the mountings for my plastic gutters to provide the structure for one of the frequencies in use. I already have a forty meter horizontal loop which is hanging in free space and is currently running on 30 meters via ?matching unit. For me and for many people, 'stealth' operation is needed and is part of the fun really. The new loop will only be at about twenty feet, and there is house wiring inside the loop - the upstairs lighting ring main for example which will be surrounded at the same level by the loop, but it will only cost pennies to do the experiment and a little ladder time to thread the antenna through the gutter brackets. Worth a try? I think so. We'll see when I get around to doing it. |

At present, I have a wire loop that goes all round the loft, following the pitches of the rafters. I'm always looking for ways to improve things, and you have given me a few ideas.
