Thanks, Colin, I guess you really do get what you pay for. I tried calibrating the offset on the Amazon ones, but then realized I needed (at least) gain and offset for each sensor, so I just threw in

sorry Hans Abi I retried again 630m doesn't work with??QDX v1_08b When I do a transmit test, QDX becomes unresponsive I think we would also have to consider the possibility of *other than* operator

Hi, I finally replaced the red LED supplied by Hans by an orange bought from our local shop. My cheap Chinese tester shows Uf 1.87V for the red and 1.91V for the orange. So, the difference is smaller

Hi Willie, So far, the Adafruit one from Digi-Key has been the best for me.?1528-1592-ND All the Amazon ones have been 5 to 7 degrees off. -- Colin - K6JTH http://tangokeys.com

Edit : the 40mini is v1.09a, the 20+ is v1.07a

Hello, I have 2 qcx, one is a 40mini the other is a 20+. Both show the same behavior: When controlled via CAT, the battery icon sporadically shows a dead battery... The expected voltage is around

Over the last few weeks I have been 'watching' a gps conditioned progrock on 42Mhz with a statistical frequency counter whose timebase is locked to GPS via a second GPS receiver. The progrock

Is it possible that this device was not calibrated (or is a cheap Chinese rip off) and doesn’t have a calibration constant programmed into it? This kind of thing is not uncommon with DS18B20

Hi All: I'm trying to use a pressure sensor, the MEAS MS5607-02BA with a U4B board - presently in the middle of troubleshooting - right now I'm not seeing any of the contents for the internal ROM

Given the semiconductor shortages it is nearly miraculous we can get anything at all! Patience will be rewarded.... -- de AI7AN

I forgot to mention band when I said my hi-band 9 Volt QDX needed 12 V to reach 4 Watts - it's even for the 20 m band. What can be the reason - a single open BS170? 73 Sverre -- Sverre LA3ZA

"just try calling CQ" - there are a lot of us working FT4 on 10m - just make sure you are seeing stations on FT8 first!

Hi Cliff, Peter Thanks for the suggestions - so simple! Terminal mode now all working OK. Peter the "Saved Configuration" is a great remedy for my short-term memory shortcomings. 73 Mike

I find it useful to save a configuration as "QDX Terminal" or somesuch. That way you get a reminder to select it before clicking "Open": Peter Lee *G3SPL*

Thanks for the reply. I did find the software that you mention. I will try it out. Enjoy Life, Greg Live Well, Laugh Often, Love Much

Neil thanks for your reply: directly using the --device= option? Does the QDX input not appear in the list of ALSA devices? (I don't have a QDX with which to test.) Neil, I thought the same thing. I

Neil - You might have a look the Python-based solution for using the QDX as "general coverage receiver" that I concocted several months ago.? I think if you do a search for my call letters, you'll
