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

Hi Mustafa ... if you promise a child an icecream and the child has to wait 😬😬😬😊 Do you have a date, the lightAPRS will be in the shop ? Also when will the code be online ? best regards and vy 73 de D

Merhaba Mustafa, congrats for this project ! I work on different APRS trackers with my friend for about a year and i think we all are on the same way :-) A few questions: Will it be available as a Kit

Hi Mikael, heard it yesterday in germany - All the best wishes for your mission. 73 de DC1MAK micha

Hi Alan, you are absolutely right - i forgot to specify that i do wspr only on shortwave... But on these bands i normaly observe no drift. I also think, the first thing, Frank should do is to replace

hallo OM Frank, because of drift i use the Fox TCXO with all my U3S. You may send me a pm - maybe i can help 😊 vy 73 de DC1MAK micha

Hi Alan, I also use the Fox TCXO in all my QRP-Labs and own projects... What equipment did you use for this measurements ? This evening i will have a look on the output of my synths... Several times i

merci beaucoup Gilles, many thanks Alan, i knew, ther was something written somewhere.... in the next weeks i'll try different clocks with my Arduino-based transmitters.... I'll report my experiences.

Hi Hans, hi all, somwhere i read about, that the reference clock of the Silab synth in a U3S MUST be at 27 MHz. Of course this depends on the firmware of the U3S. But i think, i heard that there is an

Hallo OM Stefan, ...Du hast Post 😊

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 recognized a kind of jitter when using a TMP36 Sensor. The displayed value changes up to 1,5 degrees ! I tried blocking C's in the power supply and directly soldered C's from the output pin of the T

Hi Mike, it does ! The Kit uses the standard NMEA sentences, Hans described in the firmware manual. Without the PPS you just won't get a blinking heartbeat symbol. But if you use an other GPS source,

Hi Hans , thank you very much - so there will be a lot of clocks being updated this evening 😊 73 de DC1MAK micha

Hi Hans, Hi all ! By playing around with the GPS Clock Kit, i wondered, if nobody else than me has the wish to to be able to display the latitude and longitude in different formats. The clock shows de

If this project would become real, i think Hans needs to prepare a minimum of 8000 Kits ! I see, there are organisations like "QRP-Labs-Leaks" and "QRP-Labs-Rumours"... So it is clear that QRP-Labs cu

with a MAX232 between QLG1 and a prolific USB-to-RS232 converter it works perfectly !
