Trying to run the hardware in wspr mode, but keep getting error : message. Any ideas as it happens with no message or with one. CW mode brings up the clock >00 WHICH IS COUNTING DOWN i PRESUME TO TX

Yesterday, I lost a whole day due to me reacting to an arthiritis drug, which I took the night before. Things are settling down now and scratching around, I found an old Navibe GPS unit ( looks like a

Been a bit quiet lately but looks like I'm back in business. I had 3 problems manifest themselves on about the same time which made me untold puzzlement and frustration. 1) PSU problem. U2 worked

The GPS is not needed to make WSPR work. All of my U2 WSPR work has been without a GPS. A few iterations of setting the 20 MHz oscillator frequency are required, but mine has run for more than a

Hi Tom I re-studied the code. The processor doesn't wait for any feedback from the DDS. It just talks to it and hopes it listens. However, it does expect communication back from the LCD! So this

Nobody claimed it yet! 73 Hans

Dear fellows, since I received the V2.02a firmware chip, I have one obsolete V2.01 processor in the shelf. I thought about using it as a standalone CW beacon keyer. So I set up a dummy board which

Any updates on the competition so far ? Did anyone already claim the U2 ? The 50 MHz short skip season is not yet over... Regards from sunny Bavaria, Tom, DL2WB

Paul, From what you said, a variable PS just for the final or finals might be interesting. Use a LM-317 and pot for regulator. Bad news yesterday. Was going th use my old FV-M8 for the GPS. Data out

Got some 2.03 chips in the post this morning and now my trusty old Trimble GPS module is working again... Now I can run both U2 rigs under GPS control... Happy days Thanks Hans.. Philip

Question now is, shall I rewind them all to make them look neater? Nah! no chance :) Philip G4JVF

Ahh, that's an easy one to answer. It looks like you wound the coils the opposite way to me and so had to twist them awkwardly to make them fit on the boards. 73 Keith.

Why are yours neater than mine Keith? :) Philip G4JVF

I've been doing the same... http://www.feek.co.uk/images/lowpassfilters-20130727-112046.jpg Just waiting for the others to appear in the shop. 73 Keith, G6NHU

Tom, I think that on the LPF boards, the "overkill" silk screening showing the inductors, could be used to show an image of the US resistor sysmbol, but marked as L1, L2 etc, indicating exactly which

Don, your numbers sound about right, though all of my testing has been at 80 meters. In the files and photo section you can see some screen shots of what I found there. On 80 meters I can get as

Hi John The display isn't backlit. I am considering this for future versions. 73 Hans G0UPL

Barry , I plan to use one of mine on 472 kHz. also . Would you mind sharing your amplifier drawing ? Best Regards. 73 , Charlie , W5COV
