Hi Chris, for the picture in my initial post i used a simple active patch antenna ( amazon cheap chinese) For my experiments normaly i use QFH antennas that i "extracted" out of old Vaisala Radiosonde

Hi all, i played a bit around with some GNSS stuff and found out, that the u-blox NEO modules ( series 6,7 and 8) are pin compatible to the YIC module built into the QLG1. As you can see, i tested the

QLG1 unit and change in GPS data?

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

Hallo Micha! Nach dem Aufbau der GPS Uhr mit einem 4-Zeilen Display würde ich gerne ein zweites Display hinzufügen. Wie hast Du das umgesetzt? Hast Du mehrere Clock Module an einem GPS RX angeschlosse

Hi all, I'm just before finishing my QRP-Labs "clock tower" and made some tests. Now i have two mysterious things: If i use a ublox M8Q GPS engine instead of the QLG1, two things happen: 1. Lat. & Lon

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,

Willy, Curt: Thanks for your suggestions. As I mentioned above, I've unhooked R1, so the RF module is no longer connected to the 74ACT08. The soldering is good on all pins, it just looks weird in the

I would carefully touch up all of the solder pads on the IC. It looks like you didn’t let the solder flow well enough. As someone pointed out, Pin 7 looks like it’s coming though the board but doesn’t

David , I can be wrong , but it seemed to me the padnumber of 74ACT08 wich has bad solder is pin7 and not 8 . Wich means no ground connection on this chip. Do you have a scope to measure , or someone

Hello Martin. No, it's the patch antenna, and no, there's no NMEA data coming from the chip. Reading the chip's data sheet, I think there should be NMEA at all times because one of the data values is

Hi, - are you using an external antenna ? If yes do you feed the 3.3v to power it to the center pin ? - do you see any NMEA sequence? 73’s M

Thanks everyone for your suggestions. I didn't realize that my answers wouldn't display below your responses, so I'll summarize and add my latest findings here. I removed all but the power connections

They are all the same way round. There's no signals from the RF module.
