Thanks for sharing the photo Dan. I do like the way that the itty-bitty QDX is dwarfed by everything else and I can only admire your excellent-looking matching network. I feel like a roller inductor

I also have the FLIR One Pro, and like Donald I am satisfied with the performance.? It has (I think) two ranges, the shot I posted is using the lower-temp range and it is extremely sensitive.? I

I use the single-cycle RMS measurement feature in my Siglent scope to calculate the power =? Vrms^2 / 50. If your scope doesn't measure Vrms, but does measure Vpp, then your formula of Vpp^2 / 400 is

Hello all, I've been using my QDX on FT-8 very regularly for a number of months, and somehow managed to rack up 90 DXCC entities in my log. But as expected, those enticing CQs from new DXCC entities

Is the formula Peak to Peak voltage squared divided by 400 an accurate indicator of RF watts output? I have an accurate digital scope and want to calibrate an Elecraft W1 watt meter I just finished

Are there RF Filter Sweep screen shots for 80-20m posted some place? I just completed building my QDX and it seems to be working, mainly. But I'm puzzled by results I'm getting for the RF Filter

Paul, Very interested in your FLIR camera that plugs into your Android phone. Can you tell us more? Model, where you got it etc. Thanks very much. Alan, W3AL

Should I be able to hear sounds from PC applications while WSJT-X is configured for the QDX?? My PC is mute while the QDX is running.? If I change the PC sound card settings from "Digital Audio

Hi Evan, Thanks for your help. We are making progress. Should have thought to use the dummy load, plot shapes are now sensible. Reflowed all the filter toroids and confirmed voltages on selection

MItch, I just now tried that, going from 54 to 40 on 80 meters in QDX. After rebooting there's really not much change. I do notice some change in the waterfall background level. It goes to black and

I went through the opposite yesterday and noticed that it is wise to restart the QDX after changing the audio levels. Perhaps ensure that you have done that? -- Mitch, AB4MW Sent from Proton Mail

After seeing comments about JTDX on this forum today I thought I'd give it another go. I've used WSJT-X for a long time. I worked out getting JTDX and JTAlert (for JTDX) to communicate. I'm getting
