Re: WSPR version of new kit?

Hi Alan

Then it would need different components in the audio phase shift network, which only tries to shift frequencies around the 700Hz CW target frequency. 

It's worthy of further investigation for sure!

To the best of my knowledge this is not possible.
I have spent some time with the IQ versions of WSPR
It seems to me all the settings have to be made with the aim of using 1500Hz centre.
But it does not need a filter, the noise level is measured in a wider range, 500, even 2500Hz? Peaking distorts the reported SNR.

Hi Per

I have thought about enclosures but I have not reached a conclusion. Well... the conclusion I came to, was that I needed to take things step by step! Like the Ultimate series... the enclosure came later. It is better to divide things into manageable steps than to sit and dream about everything and never deliver. It is hard to explain how much effort and work this CW transceiver has taken over the last 3 months, and to a lower level extent, before that too. Unbelievable! So let's get this thing out... then I *may* have a think about an enclosure, in time!

Hi Jan

I knew it was only a matter of time before this question came up ;-)

No modifications to the firmware would be needed. 

The two possibities are:

1) Configure the WSPR decoding software to work at 700Hz instead of 1500Hz... not sure, which programs (if any) offer this? I seem to recall seeing a setting in the original WSPR software. Anyone want to check? And does it work?

2) Change the CW transceiver hardware, to centre the audio phase shift network (not "polyphase", this time!) on 1500Hz, and centre the audio filter on 1500Hz. Then set the "CW Offset" parameter to 1500Hz instead of 700Hz.

Hi Hans

Is it possible with a WSPR version of the new kit.
The audio low pass filter center should be moved to 1500 Hz (or is there a whisper receive program available with configurable center audio frequency).
Perhaps you also have to modify the polyphase network ?
The setup of the receive frequency could be made thru the split function.

Re: No GPS info on display

qrplabs@...
 

The reason for not seeing NMEA frames was the most unexpected: the USB-to-TTL converter was faulty. Using it another one I had lying around immediately gave me a flow of $GPGSV, $GPGSA and $GPRMC frames. I have yet to study if they look correct, in which case I will be satisfied that the GPS receiver works all right and the fault has to be found somewhere else.

Thank you to all who answered with various hints.

Hello Hazarda

Ok, I uploaded the DRAFT .pdf of the instructions, yes - see http://qrp-labs.com/qcx.html

As noted on the page: This document is NOT final! It is targeted initially only for the 17m YOTA buildathon constructors. The final document will include specification of components for other bands (where the component value is band-dependent in the kit). There are a few changes to the firmware that affect the operating instructions, including addition of CW keyer "weight" configuration. There will also be measurements of Rx and Tx current, and a chart of power output against supply voltage (by band).

Hi Ted

I was there ;-)    And now the RSGB now have it on video, see http://rsgb.org/main/about-us/yota-2017/watch-our-vlogs/ ... so I guess the secret's out and you should hear it from me ;-)

This kit will be ready and on sale in about 2 weeks, and costs $49 (approx 41 euros, 37 UK pounds). NO more pre-orders, please wait until it is in the shop.

The kit is a single band 5W CW transceiver kit with lots of features. It also contains a WSPR beacon mode. I'm attaching a photo of the prototype with and without the LCD module, because it doesn't show well in the video. List of features:

Easy to build, single-board design, 10 x 8cm, all are controls board-mounted
Professional quality double-sided, through-hole plated, silk-screen printed PCB
Choice of single band, 80, 40, 30, 20 or 17m
Approximately 3..5W CW output (depending on supply voltage)
12..15V supply voltage
Class E power amplifier, transistors run cool… even with no heatsinks
Good 7-element Low Pass Filter to ensure regulatory compliance
CW envelope shaping to remove key clicks
High performance receiver with at 50+ dB of unwanted sideband cancellation
200Hz CW filter without ringing
Si5351A Synthesized VFO with rotary encoder tuning
16 x 2 blue backlight LCD screen
Iambic keyer or straight key option included in the firmware
Simple Digital Signal Processing for a CW decoder, displayed real-time on-screen
On-screen S-meter
Full or semi QSK operation using fast solid-state transmit/receive switching
Frequency presets, VFO A/B Split operation, RIT, configurable CW Offset
Configurable sidetone frequency and volume
Connectors: Power, 3.5mm keyer jack, 3.5mm stereo earphone jack, BNC RF output 
Onboard microswitch can be used as a simple straight Morse key 
Built-in test signal generator and alignment tools to complete simple set-up adjustments
Built-in test equipment: voltmeter, RF power meter, frequency counter, signal generator
Beacon mode, supporting automatic CW or WSPR operation
GPS interface for reference frequency calibration and time-keeping (for WSPR beacon)

Hi Halden

From the moment you press a paddle, the everything happens at a regular interval determined by the speed setting. If you set 12wpm for example, the interval is 0.1 seconds. All the dits come out 0.1 seconds long, the dahs 0.3 seconds long, and the gap between them 0.1 seconds. Is this what you mean?

If not, then please describe it to me so i can understand it. If a feature isn't there and is useful... then I can add it to a future firmware version. The kit has 2 x 3-pin header for AVR programming supplied. So easy firmware updates. 

The keyer also has a "weighting" feature for people who like to deviate from standard Morse timing to make theirs sound "harder" etc.

A fine kit indeed. I dreamed that it would have been a SSB transceiver kit geared towards digital modes with USB. 

It's going to take some effort to learn CW. 

Re: Program fimware V3.12 with Arduino

Doubtful that eXtreme Burner will work using an Arduino Uno as the programmer, sorry that I did not catch that in your initial posting.  It is used here on a computer with Win8 and a $2 USBASP interface.

If you must use an Arduino Uno to program, your avrdude command line appears to be the problem.  At least the wrong part (try m328p, not m168), possibly the wrong .hex file? (but I asume you renamed v3.12.hex as Ultimate2.hex?), and probably the wrong hfuse and efuse settings ... and, as Manoj and I mentioned, v3.12 only needs to be programmed with the hex file (.eep file not needed, it is generated by the U3S v3.12 firmware if needed).

Re: WSPR crashing

I also have received fatal run errors from the WSPR software. Here are the
known data in my first fatal crash:

WSPR Version 2.12_r3617
Run date: Sat Sep 03 06:32:12 2016 UTC
OS WIN 10

STOP Too many FFTW plans requested.
Fatal Python error: PyEval_RestoreThread: NULL tstate

Perhaps there is a memory leak where FFT resources are not being released
after resource requests are granted.

After a fatal crash there is a thread left running which can only be killed
via task manager, otherwise you will not be able to re-launch WSPR.

I complained about the bug in the WSPRnet forum, and was told that for the
price I paid for the software, expect a bug-or-two. I was also told to run
WSJT-X as a solution to the crashes. You might consider switching to that
program too.

After many years of WSPR running 24/7 it has started misbehaving and I have
no idea why. Help / advice appreciated.

OS is XP 32bit
WSPR is presently vsn. 2.12_r3617

WSPR has always given a runtime error after a few days operation, which
didn't appear to effect he operational functionality. I have never been able
to read the error report as the runtime window flashes up and disappears
before it can be read.

Now, the runtime window appears, sits there with no error report or any
other message for a few seconds, then closes without opening the wspr
graphic window.

I have shutdown and rebooted the system, it didn't recover operation of wspr
I have uninstalled WSPR, and deleted remaining crud left on the machine.
then re-installed WSPR 2.12_r3617 with exactly the same behavior as before.

How, if I get a runtime error window, do I keep it on-screen for long
enough to read it?.

all help appreciated. thanks, Mike

Mike,
Sp3, all "latest" updates?

WSPR is presently vsn. 2.12_r361 > WSPR has always given a runtime error after a few days operation,
On my system I have run many versions of WSPR for weeks on end, usually 2 or 3 instances at once.
But recently one version v3.00 r2309 has been stopping after a few days with a runtime error, not bothered to note it but will next time.
I can not think why, I was wondering if an apparently different update (something like Java or Firefox etc.) or software installation had affected something.
I probably have installed programs, certainly WSJT-X v1.7.0
Have you changed/added anything in your system?

I guess you need an IQ version? There are alternatives but somewhat more complicated.

On my W10 machine early versions of WSPR ran, then all failed to load. But I just accepted that, I think it was a runtime error but I can't test, I removed them.
