Ultimate2 statistics
Hans Summers
Hi all I finally got round to typing all my order details into a big spreadsheet and doing some statistics. From time to time I'll update the charts.
1) The number of LPF kits that have been ordered so far, total 637. Remember, not all of these have been sent out - there are 48 Ultimate2 orders currently pending since the first set of 200 sold out and I am getting the new set together. So the numbers in the chart includes the sent and the unsent orders.
2) The shipping information. Thank you to everybody who wrote to told me when their kit arrived, I have compiled all this information and arranged it into a table, by country - so that you can see the minimum, average, and maximum shipping times to your country.
See? 73 Hans G0UPL |

Re: U2 spotted
Andy Cutland
Thanks for posting the image Eddie, My signal looks ok, I've never really studied what a wspr signal should look like but mine seems to be able to be decoded on any band. Current status with my U2 is I'm working on trying to get the gps working. I think I may have blown it though. I will post a separate heading. Cheers 73's Andy GJ7RWT From: g3zjo To: QRPLabs@...

?
Hi Group
I will start a folder of captures of the U2. To start it off here is GJ7RWT U2 on WSPR this morning. There could even be other U2's there, mine is shown but is merely on soak test into a dummy load, its trace is distinctive being smeary due to the band width issues and will not be on air until sorted. 73 Eddie G3ZJO |

More O/P equals more efficiently running O/P stage & less heat. 73 Eddie G3ZJO |

U2 and all LPF kits finished
"dd5cf_colin"
Hi to all members.
I have just finished building the LPF's and I get about 500mW on 160m up to 17m which is about 300mW and then for some reason 15m = 70mW only and 12 and 10m must below 10mW (my digital PWR meter readout does not show 1's) the BS 170's get quite hot on these 3 bands I have checked the 15 12 and 10m LPF's for mistakes but cant find any. I run the kit on 4 x 1.2v rechargeable AA cells and just the two BS170's that came with the kit, ideas or comments would be greatly appreciated 73 Colin DD5CF / G1ZOS |

Re: Something else for the wish list ? (plus other thoughts)
Hans Summers
Hi Andy I'm very glad that you are enjoying yourself with the kits! Thank you for the patience while I sort out the issues. We have a lot less issues this time than with the original "Ultimate" kit (a.k.a. U1). More enhancement requests, less bugs :-) ? But the bugs are there, and they'll be all solved soon.
Gradual progress too, on the accumulation of the components for the next set of 200 U2 kits, and the components for the LF bands (475kHz LPF, 135kHz LPF). Yesterday I ordered 400 ATmega168 processors - 200 for the next round of kits, and 200 spares.?
Some delay has been caused because my supplier of the DDS modules has changed the 125MHz crystal oscillator component! The new oscillator is a surface mount kind, rather than the current large through-hole canned oscillator. For some days a stalemate existed where I have paid, but I don't accept the change (which I was notified of only after I had paid). As a compromise they are sending me one module to test to see if I like it. If it's Ok, then I'll accept the rest.?

Well I suppose if it's possible then that would be a nice addition, but I'm sure you have better priorities in life ;-) At this point I'd like to thank you for all the work you have put in to these little kits. I've been so busy playing with the U1 and U2 the last 6 month that I've probably not mentioned my gratitude, or spoken very much to the XYL - because of all the time I've devoted to building these little gems ! I am surprised that there is not much written in any major publications about QRSS and these odd modes. Perhaps we really are a minority with our experiments. I've been quite taken by both WSPR and QRSS of late and learnt a lot. I think QRSS is often seen as poor relation to WSPR, but where else can you see what looks like a chart recorder of yours and other signals to compare them by. WSPR doesn't make it easy to compare the performance of other stations without a lot of to'ing and throwing about on the WSPR d/base. QRSS grabbers fit the bill nicely and show up all sorts of other effects that WSPR could never do. Multipath distortion, ionospheric oddities, auroras etc. And then there is on the grabber traces what I call "ionospheric bend". Not bending the ionosphere but the bend in the grabber trace which you see on a stable TX when the ionosphere is changing height and shifts the incoming signal frequency by about 1Hz. I see this often on the W4HBK grabber on my signals on 10Mhz. Fascinating stuff, and I think there is more to come. 73 de Andy G0FTD --- In QRPLabs@..., Hans Summers <hans.summers@...> wrote:

Ok well I think I have space for it.? I removed a feature which I have never heard of anyone using which is the "Inv FSK" feature. Removing that created a little more memory.?

I often hear newbie beacon watchers saying that they've heard weird beacons using funny Morse, and I have to explain to them that they are listening to the wrong side of an FSK CW signal :-) Kind regards, Andy |

Hi Andy Ok I think I get it. So you're saying you want a fast, wide FSK mode for use on 10m, with speed entered in WPM and supporting FSK up to 999Hz. Wow. Do people actually *use* this!?

Thanks for the quick reply, I thought that was what I had to do I will have to use the trial and error method here. 73 Colin --- In QRPLabs@..., Hans Summers <hans.summers@...> wrote:

We know you have not got enough to do :-))) When you say "speed setting in WPM" - doesn't the kit already doUnless I'm mistaken - not quite. As I understand it, the speed setting is the WPM for the ON/OFF keyed CW, and the dot length on QRSS/FSKCW. What I had in mind was speed in WPM for the WIDE FSK CW mode. . FYI I have been working this weekend on the "wish list".Excellent, we all knew you'd do it ! 73 de Andy G0FTD (U2 on 7Mhs WSPR going like a rocket at the moment) |

Re: UQRSS 2 kit finished and first spots on 40m
Hans Summers
Hi Colin?
Section 9 of the manual, on page 28, deals with calibration. You need to determine the frequency of the 125MHz reference oscillator and enter this into the "Ref. Frq." configuration setting.?
It that's your only mistake, you're not in bad shape at all! Easily fixed :-) 73 Hans G0UPL |

Re: Something else for the wish list ?
Hans Summers
Hi Andy Ok ok ok. I'll add it to the list! When you say "speed setting in WPM" - doesn't the kit already do this? There is a CW mode, where the speed setting means WPM.?
FYI I have been working this weekend on the "wish list". I solved the DDS resolution issue and I'm now working on the GPS issues. I did several of the enhancement requests too, including support for WSPR-15.?

UQRSS 2 kit finished and first spots on 40m
"dd5cf_colin"
Hi to all members of the group,
I have just finished building the UQRSS 2 kit and have been spotted on 40m, I entered a frequency of 7.040.150 but am being Rxed on 7.040.070, do I need to change the DDS frequency or am I missing something else? I made one mistake, after building many of Hans's kits I read the instructions through three times and refer to them while building but I still put the switches on the top of the PBC :o) I had some others so I soldered them to the bottom and will remove the when boxed with switches on the front panel. 73 and thanks for a great kit Hans.
