Re: WSPR on 20 metres with Ultimate Beacon?

"TONY_VOLPE"
 

Thanks Stephen,

I'm not sure exactly what the crystal frequency should be for 20 metre WSPR. The dial frequency when using an SSb transceiver is 14.0956, but the receive frequency is between 14.0971 and 14.0973. I think that's right at least. I expect it should be 14.0971.

Thirty metres is fun, but most of the receiving stations are now up on twenty metres. As of now there are 35 stations world wide on thirty metres WSPR and 94 on twenty.

At the price these great little kits are, it would make sense to have one for each band.

Then I need to figure out how to be a good citizen and run a receiver alongside my little beacon. Otherwise my ops will be all 'take' and no 'give'.

Keep up the good work.

WSPR on 20 metres with Ultimate Beacon?

"TONY_VOLPE"
 

I wonder how much it would cost to do a group purchase of crystals suitable for 20 metre WSPR with the Ultimate QRSS beacon?

I think Hans and Stephen got the 30 metre crystals specially made, so maybe we could do the same thing?

I'm really enjoying the thirty metre beacon. I got seven WSPR hits from VK7AM yesterday and five this morning. Not bad for 200 milliwatts.

Aha!!
Well done dave, G4FEV! I have been tearing what little hair I have left, out regarding the fact I had no qrss or cw and was convinced it was operator error. This has to be shoddy quality control which I hope will get corrected. Jon GM4JTJ
Re: Message Error

Stephen Farthing
 

Hi Kevin,

If you look at section 6.3 of the manual under the WSPR heading it
says that your callsign must be 5 or 6 characters long to satisfy the
requirements of the WSPR encoding algorithm. When Hans wrote the
software he had to abide by the rules set down by the WSPR people.
However you could try putting a space at the end of your callsign
which is acceptable.

Let me know how it goes,

73s Steve

Re: QRSS beacon kit question carrier out only

I have the same problem with the constant carrier, apparently Steve and Hans are aware of the problem and are trying to sort it out and will be sending out new chips when the problem is solved.

Yes I had the same problem Nigel. Found the CW output on Pin 16 of the PIC instead of Pin 14.
I carefully cut the track going to pin 14 and used some very fine enameled wire to join the track with pin 16.
The CW modes appear to work now with the keying appearing on IC2 pin 8.
Looks like someone may have programmed the wrong pin on our PICs!
Hope that helps....... Dave G4FEV.

CW Modes Pin 14 swapped with Pin 16

"davyying"
 

Just completed my QRSS kit and discovered there is no output on the CW modes. The keying should appear on pin 14 of the PIC but nothing is there.
I discovered the CW output on pin 16 (an unused pin in this project).
Has anyone else discovered this?

Re: Grabber set-up 7mhz

"ferrymanr"
 

I now have WSPR running on the Raspberry Pi with the latest raspbian wheezy on my SD card. WSPR works but I have problems with using a CAT cable as the RPi USB doesn't seem to like the load of the sound dongle and CAT cable at once. I suspect this is a firmware/software driver problem that may be resolved. G3WKW had posted a page on his original installation using an early armhf image at and now updated to
I had a few headaches at first but it now runs stably on my RPi, both decoding and transmitting using VOX instead of PTT. This proves that not only WSPR but other similar applications should also be possible on this machine. I suggest you go to and search for WSPR.

Hi Hans, I have just brought one, not too bad for ?24.00. I have noticed that I will have to put a 3.3v regulator (L78L33) and a couple of caps in line to use the 5v GPS supply on your board. 73 Derek.

Hi Andy
I too would love to get my RaspberryPi setup as a grabber (low energy costs).
Since there is no audio in, then it would need a USB sound dongle I presume...

No idea about software but fingers crossed, some clever person will
do the honours at some point..

Post if you get anywhere with it

My intention is to set-up a grabber on 7Mhz I have several receivers in mind my trusty ft 817, but i don't want to be taking the grabber on and off when I want to use the 817.

So I have I been fiddling with a but am having problems wrangling it on to 7mhz dead. Or falling this I will build a DC receiver.

The main point of this post is to enquire if anyone has had a go with a Raspberry PI yet with QRSS (I Have One)? I was thinking I have a 7AH gel cell PV panel, the PI but I am missing the knowledge ref UNIX QRSS software Grabbers. So if anyone has any suggestions I would be grateful.

Hi Steve
?
Many thanks for the info and advice..? will wait till I hear later from you on results. Am anxiously awaiting delivery of the kit. I have had stuff from Maplins in 7 days, stuff my son sends me from Scotland has had a turn around of 4 days.? Good old British Mail. Ours is Camel mail at best lol.

Hi Alan,

Thanks for the message and raising the subject of GPSs.

Hans and I are doing quite a bit of work with GPS at the moment and
hope to recommend some that we know will work with the kit. We will
produce some written guidance however this note should help for the
time being.

The GPS requirement is :-

1. A one Pulse Per Second TTL/CMOS output to run the beacon clock and
also the frequency stabilization function.

2. Output of a NMEA datastream to provide data to the beacon to
construct output data such as the Maidenhead Locator. Some GPS modules
default to this mode, others require a string to be sent to the GPS.
The type to get is the one that defaults to NMEA, the other type will
not work. Other GPS do not use NMEA at all - e.g. some from Motorola.
You don't want one of these either.

Having said all that if the GPS has a 1PPS output there is nothing to
stop you using this and putting in the Maidenhead Locator yourself.

Sadly it is unlikely that a USB GPS will work for the time being. The
reasons for this are that :-

1. USB devices require a host computer to work - the interaction
between the two is controlled by a piece of software called a Driver.
We do not have a driver on the AVR chip.

2. They do not have a 1PPS output,

Some GPS Modules do not have a 1PPS output pin on the board - though
you may be able to find one by opening it up and connecting a wire to
a 1PPS output on the GPS chip. Finding out which pin does this is
difficult unless you have access to the documentation. The 1PPS pulse
is very narrow and most scopes will not see it. You might need a logic
probe with a pulse stretcher to find it. And/Or you can find the
likely pin by checking out the data sheet for the chip. I seem to
remember that EI9GQ hacked a GPS sold by MAPLIN (the UK equivalent of
Radio Shack) to do this but I cannot find the reference.

I have just ordered one of these :-



to carry out some additional work on the GPS functionality. PLEASE DO
NOT RUSH OUT AND GET ONE UNTIL I HAVE VERIFIED THAT IT WORKS.

Hope this helps.....

Steve
