Hi Joe According to the datasheet of the E108-GP01 module it supports: GPS (US), Galileo (Europe), Glonass (Russia), BDS (China), QZSS (Japan) and SBAS (Satellite Based Augmentation Systems).

Additional info: I am confident that the Low Pass filter coils and capacitors are all correcty soldered and that there is full continuity between parts as required. I have tuned the LPF for maximum

All: The ARRL has sent out a $10 coupon to all member that can be applied to any book over $14. Obviously, I have a great idea which one that should be, but many of you already have that book. (Thank

Talk: 8pm UTC, Tues 9th Feb - Long Island CW Club - learning and improving morse code for all Howard WB2UZE will be giving an entertaining and very informative talk on how to learn morse and to

Hi. I use my QCX40 for wspr and maybe a couple of daily cw qsos. The wspr obviously gives the PA a hard time with its 2 minute key down operation. It usually runs wspr overnight at least and sometimes

Great to see yet another excellent improvement from Hans and QRP Labs. I just ordered 3 of the QLG2 modules, to replace one in use, one for a yet to be built clock, and one for the QCX+ have yet to

Hi Bob USB-micro connectors are less robust and durable than USB-B. A lot of the phones I've used over the years which use USB-micro, end up have connection problems. Even my current phone with a

Hi All: I got it done! I ended up with a data set for 40m, for the 10:00 UTC hour. 52,300 observations. The frequency of each time slot is attached ... looks like (assuming a 10-minute frame) the

It would be very cool if the new GPS had the ability to do RTK.

Nice product. I'm wondering why you used a USB-B connector rather than either of the 5-pin mini or micro USB connectors? That might have made the footprint a bit smaller, unless you already had plenty

Hi Bob I agree... most people seem to think the washer is the heatsink but it is not. It is just the mechanical means to force the flats of the FETs against the PCB, which is the real heatsink.

Very nice "cooling" article. You probably should put some thermal compound between the FETs and the large solder pad on the circuit board, as that's the primary heat sink for those transistors. The

I know you have managed to get this going, but you need to enter a frequency for park mode, I believe this is used in the cal process, you need to allow a min of 60 seconds for calibration, if you

Hi, I've created a blog post on how to replace the QCX Mini AMS1117 regulator (I've used a regular 7805 but the same procedure also applies to the 78M05 in SOT223 or So-252). QCX Mini - Replacing the

Hello Chris The supplied external antenna is the only supplied option. You could, I suppose, connect your own onboard patch antenna with some modifications, but the PCB has not been designed with

Hans, Yes, various programs some here https://sites.google.com/site/g4zfqradio/incircuitprogramatmel168#h.xgcklhbd8exw Some use NMEA, good enough for WSPR, some use PPS as well although a real COM

Is there an patch antenna on the board that you could also use, or is the external antenna the only option?

Hello Steve Yes! There is a jumper on the PCB so you can choose to power QLG2 either from the 4-pin header that you would connect to an Ultimate3S (for example), or from the USB connector. The

Will it be possible to power the QLG2 from a computer via the USB connector? Will the QLG2 be suitable (without additional hardware) for synchronizing a computer clock for portable WSJT-x
