Hello DC1MAK, Thursday, July 4, 2019 Thanks again Michael, good to know a ublox is a direct pin for pin fit on Hans' board! Best regards, Chris 2E0ILY mailto:chris@chriswilson.tv D> Hi Chris, D> for t

Does somebody know if functionality of Clock and QLG systm can be affected by planned "reset of week number" in GPS data (as of April 19)? Message with warning: https://rntfnd.org/2019/02/13/the-gps-w

Chris I usually throw away all of my "geriatric battery cells" as they are too slow and lose their minds! 😂😇🙂

Hallo OM Stefan, ...Du hast Post 😊

I think I've done as much troubleshooting as possible so I've ordered another kit. When I arrives, I'll compare the two and find out exactly where the trouble lies. Thanks everyone for your help. 73,

Hi Hans, many thanks for the answer! Yes - I have programmer here and can try to load new firmware. It's a pity that my latest order (U3s-160m) is probably on the road to me already as it was possible

Thanks to all for your replies. The battery voltage is holding steady at 3.09V, when the QLG1 is not powered. Other comments suggest that the times-to-first-fix I measured were normal, because the QLG

Just for full picture - having Clock kit, FW ver 1.01, delivered week ago... Maybe I will try to go to some other "border" of LOC to see if calculation will be wrong also or I will try to find positio

Bill, Take a look at page 93 in the QCX manual. You set the wspr power in menu 6.8. If you set the value to something other than the values listed in the manual, you will get that error. Mike M Ku4qo

Phil, it should measure 120Kohms; 120ohms. 73, Jim W7EED

The path from Pin 8 of IC3 to L1 should be 120K as it goes through R43. If ita a short that would explain your deaf Rx. Peter G3JRH Sent from Mail for Windows 10

What I meant to say is that after my failed attempt to read the NMEA with my laptop. I used the Raspberry PI which I used to reflash the firmware, because I knew for sure this serial connection was wo

Built a QLG1 GPS receiver and clock kit to use as my shack clock. Works perfect. Just got another QLG1 GPS receiver for experimenting and perhaps WISPR. Built the QLG1 and powered it up. All seems ok

This section of the troubleshooter page gives some idea http://qrp-labs.com/qcx/qcxtrouble.html#pa . (High voltage on collector when TX if not is Q4 working?) 73 Alan G4ZFQ

I wanted to free up my IC7000 for "real" work so I purchased a few kits / modules from QRP Labs hoping to build a dedicated NDB / Navtex (and/or DGPS) receiver. The result is a GPS disciplined VFO dri

Yellow LED is on all the time. No blinking. I'll attempt to attach a 5V source directly to the board and see what happens.

Thanks, Roger. That was it...FB! Kent KC9LIF

Good evening Harri, Glad you found the info useful. :-) Alan

Hi Jim you can use a 7486, exclusive or to check the frequency. Put a LED and a resistor 220 ohm on the output and connect your rubidium, 10 MHz, to one input and the GPS disiplined VFO, 10 MHz to the
