Experimenting with 15m today, I did have the start up problem (power and swr going full scale) but a couple of power on/off cycles cleared that up and I'm now getting some

Yes Hans Its a funny arrhythmic problem when it variable. I have done some more investigations I will contact direct. 73 Eddie G3ZJO

Is is a good idea to have a small indication on the LCD when in normal operatin gmode that indicates that the GPS has locked ? That would save having to check the DDS Ref Freq menu. Hans ? 73 de

As the other Andy says, more confusion. Although I remember you having your signal on 28MHz WSPR on your Grabber and the tone spacing was most strange, stretched at the bottom. Probably WSPR can

Oh no - more confusion ;-) 73 de Andy

My U2 kit was also very happy on 10m wspr. I moved it to 20m now and all is well there too. 73's Andy Gj7rwt :------------------------------

It's quite entertaining that ADAfruit call it the "Ultimate GPS module".... and here we are playing with what *I* called the "Ultimate" QRSS kit! 73 Hans G0UPL

All Amazingly, Aldo IW2DZX continues to operate 10m WSPR successfully with the Ultimate2 kit, see http://tinyurl.com/plqpk29 Aldo tells me that he is using 3x BS170 transistors in the PA, operated

Hi Colin Yes, I see. Yes, you can provide a battery voltage > 7V, through the Vin pin, on my QRSS Arduino shield. The QRSS shield provides access to all the usual Arduino connectors on the two 6-pin

The DDS oscillator will have its calibration figure altered by the GPS 1PPS, changing up or down from 125 000 000 and of course the signal output will be accurately on frequency. Providing you have

Might not be a silly question. How do I know when the U2 is frequency synchronized to the 1PPS. 73 Peter G8AEN

Tony, I've got an adafruit GPS unit (http://www.adafruit.com/products/746) which I've connected using four wires to the U2 kit: 1pps, +V, gnd and data. It has the ability to run with a battery

Hi Hans here is the link: http://arduino.cc/en/Main/ArduinoBoardUno it is about 1/4 of the page down. 73 Colin

Hi Colin All of the standard Arduino pins are fed through the shield in the standard way. So if the website recommends that the Arduino can be powered by Gnd and Vin through a shield, this would

Keith, Could you say more about the battery backup you added? What is the exact voltage on your system? How is it different to what you had before? I have not been able to get my EM-406A to operate

Hi Hans and Alan, Thank you both for the information and the links Alan. Have you any advice for me about question 1 of my last post: If I run the ARDUINO UNO on battery power can I connect it to

:-) . I don't know, I hoped you would. PPS < ???25 ns @ 50% was copied from the manufactures data. Its very short, I can't see it on my scope all I can get is a trigger from its leading edge so I
