Guys, I have a theory but I need to test it. Steve

I am running 2 UQRSS, ver 1.04 & 1.05, both have the same parameters and are configured for 30m WSPR. ver 1.05 has now been running for 4 days with no problem, both with GPS. After reading these posts

Perhaps an obvious question but did you check the signal at the CLK pin of the processor? (Pin 9 I believe) *** ________________________________________ From: QRPLabs@...

I've ben comparing our spots Philip on the two bands. It seems that 20 shuts down much more at night than 30 does. I had USA stations all night long more or less, but none from South America. I wonder

Hi Tony, Ok - looking at the one eighth speed your kit is running at, for my suggestion to be right the oscillator would have to be on 1.2675mhz , which it obviously isn't. That would leave a

Tony, Tried that! Using a 'scope & counter the xtal oscillator is definitely running at 10MHz! Tony G4CQS

That's a very strange thing to happen. I just built a new one (I had one already) and it is the same issue of the kit as yours, but it behaves perfectly. The settings look normal. I replicated

Steve, Same here! Received my kit last week. The clock as displayed on the LCD runs ~8 times slow. Using QRSS with speed 5 it takes 40 seconds to send a dot. In addition the FSK pin of the uP ((p15)

Hi Guys, I'll wait for Hans to comment on this as he designed the hardware and wrote the software. I think he might be taking a short break so please be a little patient. If anyone else has a problem

Just got mine last week- fired it up today and got the same situation- way too slow. Every thing physically looks good but is beaving exactly the same as yours. ? 73,

20 meter WSPR screen grab in my photo album (G4JVF) on here...wsp20.jpg

Had a one off crystal made by QuartSlab...Bit expensive but worth it I reckon.. The crystal frequency is 14.097100 HC49U 30pF parallel.. With C5 removed, I can tune below/through and above the WSPR

Hello all, first many thanks to Hans G0UPL for the quick delivery of the kits. The first one I have built up yesterday, but struggling with a problem: The MCU seems to run much too slow. This is

Got a 7.04 Mhz crystal from the GQRP club online shop for ?2:00 Anyhoo, with C5 removed it tunes nicely through the WSPR section of 40 meters.. Getting a nice selection of spots this

Hi Jon The kit requires only the $GPRMC sentence. It will listen to the input data stream and watch for $GPRMC. Anything else, it will ignore. So you can leave in the other sentences or not, it makes

Folks, my Trimble Lassen SKii provides as factory default the following $GPVTG,000.0,T,004.6,M,000.00,N,000.00,K*4C $GPGGA,190341.0,4250.928,N,00240.901,W,1,06,1.78,00593,M,051,M,,*4D I guess I will

Maybe a set of jumpers to support using a common antenna, or using an off-board relay to switch antennas? This way the user would have options for antenna selection. This avoids having to include a

Hans, & others... Might it be possible in some future version of the U-QRSS unit to have the uP use it's FSK ability to switch operating frequency between QRSS and WSPR segments of the band? If that

Hello Hans, Forgot to mention that a WSPR/QRSS tx kit for 500 Khz would be very nice. Did some work on that band (also 136 KHz) and with 1 Watt could reach a 500-600 Km. Did that with a simple 6

Fb Tony, Nice picture and can see very good now what you have made. This way it is very easy to change Capacitors and do experiments. Yes the Magnetic Loop: It is with the size of 150 by 150 cm
