QRPLabs This morning I got round to sorting my arrangement for using my external LPF's with the U2. I now have the possibility of output on any band except for the moment 136KHz. The 200mW of RF out

Hi Keith Can you give me a photo of how it looks with the digit missing off the right? Or, write out exactly the display, character by character? Then I can try to get it corrected/moved. 73 Hans

Ok Andy, Colin! Ok! I will add an indication that GPS lock has occurred! One more for the wish-list! 73 Hans G0UPL http://www.hanssummers.com

Hi Eddie That's an interesting request, and I can certainly see the use of it! I added it to the wish-list! 73 Hans G0UPL

Hi Hans, I've been doing some testing and changing the SPEED parameter so that my callsign fits nicely in ten minute frames - If I set speed to 10 then my callsign fits with 20 seconds to spare so

Mmmm, tried "all"? settings. freq stays at 125.000.000. Time does not get updated It seems to sulk with GPS on and do nothing. tried inverting and all pulse width up to 50%. GPS is GARMIN GPS16 LV

Also I forgot to add something regarding my original spectrogram tests. Whilst watching the signal when receiving only the two bit streams, the same could be heard on the receiver. It was just like

Well I know for a fact that I did have my own 28Mhz WSPR decoding at one point on whatever 10m random freq I chose for the test. Then I moved to another, and it all went skew whiff. I have no doubt

When entering Message Data it would be nice to have the right button (Scroll Mode) scroll through the alphabet A to Z then stop waiting for a press before scrolling again through the symbols to the <l

That sounds like a good idea to me, how about some 'square brackets' around the Locator i.e. in my case IO84 becomes [IO84]? 73, Colin M0XSD.

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
