Hi Bojan, have you set a transmit delay time? This stops the ‘tune’ feature from working. Try setting the delay to 0. 73 Ken g4apb

Larry, Dow Corning 737 Natural Cure Sealant Clear is great for securing toroids to a PCB. It is natural cure sealant which means it doesn’t give off acetic acid when it cures, and it won’t

Larry Securing toroids is important for a vfo circuit to keep frequency stable. For a low pass or bandpass filter, not so much it won't matter electrically if it moves a bit. I doubt you have a

Hi Ron, Thanks.... !!! Instead of trying TX using my dummy load.... a lot too close from the QCX..... I tried with my dipole and listened myself using a websdr in Florida as you suggested. I was able

Jeff, a scope on FFT mode will show lots of harmonics if the input settings aren’t right. Try adjusting the vertical gain for a peak to peak voltage swing of two vertical divisions max and see if it

I use a drop or two of clear nail polish. I keep clear, red, and a few other colors on-hand in the shop to secure things like that as well as putting a tiny drop on multiturn pots, etc. when I fix

Hi Ron, I also tested with my FT818 at 1W into a dummy load..... it is clearly cleaner than my QCX, without any doubt..... My QCX+ seems indeed to have something weird... the tone is lousy and even on

Thank you for your thoughts Larry NA0F

Jeff, you are too close to your IC-7300. That's what's causing the distortion. I get the same results with my QCXs. Try listening for your signal on a WebSDR or have a friend listen and maybe record

Hi, I have strange problem. RX alignment steps have been done within expected results... BPF around 8 + half scale... IQ and phase at minimal around 7. TX output measured with my scope and a dummy

Speaking POTA: On SOTA, it's very easy to self-spot by sending an APRS message addressed to SOTA. Is there a similar way to post a POTA spot? Thanks, Bruce Prior N7RR/VA7TO

Thanks, Jakob. I'll keep trying. 73, Bruce Prior

The 30m is not a bad band for CW and is somehow open most of the day. Call QRP on 10.106 MHz or SKCC on 10.120 MHz and you may get a response quite quickly. (Join SKCC if you can use a straight key,

Great question. I have a 40M, because I like the CW opportunities there regardless of time of day.

Sorry. Mine is actually the QCX-mini model. 73, Bruce Prior N7RR

I bought a 30 m QCX version quite recently, and I'm concerned that I may have made a mistake. In several days of listening, I haven't heard any CW signals, only some of those exotic extremely-slow

Sorry Mont, and all - I got confused by the similar numbering, and went off in the wrong direction. (Not that the info isn't useful, it's just not where the reported issue was!) I'm sure I'll be

I realize that it's confusing and that I didn't clarify well. Chill out. -- Julian, N4JO.

Mont, I'm referring to his comment about measuring the voltages around the circuit, not to the aspect you're addressing - that of the connections to the display. Specifically, this information OP

Good, hopefully the LCD will work once you resolve this. All Julian's comments are very valid for general troubleshooting. If you have further issues, I'd print out his last post for a reference for
