Nice, thanks for keeping us updated on your progress! 73, Willie N1JBJ

Thanks for the reminder, wanted to order one for my golf cart: https://www.amazon.com/s?k=steering+wheel+knobs 73, Willie N1JBJ

Hi, I am, using the QRP Labs 50W C class amplifier with QDX transceiver.? It is doing a good job.? When I measured the S21 parameter I have noticed quite a difference in gain.? The slope is from 16

A photo of the early stage of breadboarding a RP2040-Zero (Waveshare) loaded with?Kholia's V2 version of Mike's SWR/Power Meter software: The OLED display is from a ATU-100 kit I have; the circuit

In the auto industry, they called them suicide knobs because: Knob would leave an "impression" on the driver's chest in an accident Knob would catch on something (clothes or such) and steer you into

Graham and Ted, See the discussion at /g/QRPLabs/message/85457 (near the end) for the various mods. Lou? ?W2ROW

Ken, I simply made a 5 pole filter as fitted in a Softrock. I omitted C11 as I had no idea how to calculate its value, or whether it would need a different value for L4. I've not checked harmonic

Yes, that's a cute tuner (or a good box of parts) for the money.? But what are the mods to that which are spoken of, and what advantage do the mods have over the original design? Tnx, Ted K3RTA

Alan, you said; After configuring all bands to use the 10m LPF ….. How did you get a 10m lpf on the qdx please? I looked at Hans lpf schematic and downloaded the ‘Elsie’ lpf calculator

Speed knob = a “finger dimple” is the small outer thing sticking off the knob in the photo so you can just put your finger tip in the outer thingy and spin the knob faster than just using a finger

Hi Ken YES! You can call the EEPROM file whatever you like, when uploading to the QDX. When reading (downloading) files from the QDX, the file names listed as the contents of the "USB Flash disk" are

Graham, I think this is the tuner they are talking about.

Can you please direct me to the recommended mods for the $15 tuner Thank you

I found a way to listen to what the QDX hears. Now CW can be decoded by the wetworks between my ears. Keying is something that I have not figured out. I have a Morserino, and I was thinking of porting

Hey there. Thank you. This is very useful. I was able to implement this with a QDX Transceiver.

I'll pretend my name is Al ?. ?I use the infamous $15 ebay tuner that I've made the recommended mods to. It's a perfectly good standard T-match. I tune for maximum hiss just like we used to do in

I just ordered the same 8GB kit.? I love the case.? Also ordered an additional 12V 3A filtered power supply.? Something QDX related might use it. Mark K9TR

Thanks Evan. I will give that a try. I'm on W10 Pro so I should be able to find the settings. Tnx de Arnie W8DU

Why wouldn't I understand ? I've been licensed for nearly 40 years. Did I miss something ?
