It's interesting to see the and understand the linguistic diferences in different parts of the world. To be "pissed" (US) = feeling angry. But in the UK or Aus it means being unduly influenced by

Hi Colin Firstly, are you correctly referring to image rejection (the superhet image 24kHz away from the wanted signal) and if so, how are you measuring that? Or are you referring to unwanted sideband

Hi, Peter Since the first 2 words mean "get angry" on this side of the pond, rather than "leave", over here the second and third words are "On Everything". 73 Jim W4JED

Hi Ken, Unless you are in the directory where those files (/qdx_ui_103.py/ and /qdx_sdr.py/) reside you'll have to use a full path name, such as sudo chmod +x /home/pi/qdxsdr/qdx_ui_103.py.

Bob It is push-pull so 2 would probably be better. But the LPF switching would have to be changed or removed, 1N4007s are unlikely to be loss- free at 60MHz. 73 Alan G4ZFQ

American hams/former CBers will understand this. When 4 watts isn't enough, GET AN AMPLIFIER. FWIW there are still loads of CB amps floating around, and some of them still work. Even if you get one

Hans, A little off topic here but what power out can you expect with 3x BS170 on 50MHz? I know QDX is not a 6M rig ( yet ). Would 1X BS170 be better than 3 (at 50Mhz) to lower gate capacitance? TNX!

I bought one of the Chinese tuners and sat on it for a while.? Eventually I decided I would rather have a Z-match tuner instead.? (see attached picture).? Most of the parts worked in the new

Sorry I meant 500mA current. Typo. Power dissipation rating 833mW "More powerful transistors" go hand in hand with higher device capacitance. Efficiency goes down, driver power goes up, heat

I was just digging into this. I am only 20 db down on 20M and 80M and 10 db down on 30M and 40M. Is there a way in hardware to adjust the phase of the IQ signal? Thank you, -- Colin Kaminski - K6JTH

I'm using WSJT-X 2.5.4 on Linux (Raspbian). For audio input and output, I use: plughw:CARD=Transceiver,DEV=0 ...in mono. And it works. Sometimes. I already made a couple of QSOs with these settings.

Hi Gary Not necessarily an oversight, but certainly a compromise. Adding current protection and VSWR protection can be considerable extra cost and complexity and many QRP radios do not include these

Caution!!! Voltage is not the problem with the QDX, and winding T1 with 2 or 3 turns has little relevance, other than to say that 3 turns enhances the exposure. There are two built in design
