Well at the risk of looking foolish I need to ask about this bino. I've wound a few of these in other projects but never been certain I was doing it right. I've wound T507 opposite handed. That is

There's also the DIY option: https://vk3il.net/pressure-paddle-v2/ They seem fine to me, but my CW is pretty marginal. Other more serious CW operators also seem to like them.

"After assembling my QMX+, applying power, and pressing the encoder switch, I saw 170 mA current draw but no LCD backlight and no USB port recognition." This is normal. You then need to load the

My QMX+ kit hasn't shipped yet, but I agree a thinner case would be a nice option. It seems you could make your own shorter end plates and then try to mod the front panel connections to orient it

4SQRP has a kit and I am happy with the result. Not a Kent but fine for QRP/portable use. Larry KB3CUF [email protected]> wrote:

Safe options: 1. Tune with 705, then connect QMX 2. Resistive bridge in front of any tuner - switch to straight thru after tuning up. A lot of manual QRP tuners integrate this into the tuner 3. Use

Can you clarify the procedure for using a manual tuner and the Tenna Dipper II? Note, I also have a Z-match tuner (which I have not tired out) and RigExpert Stick 500 which I have used to tune an

Good for you. In my case, im try in two phones, and dont work. I hope hans fix this bug soon. ??

This is with PCB#2 not connected to anything?? If it is plugged in then there's a lot on the main board that will take power. Looking at the circuit Q111 might conduct through its diode but there

*UPDATE:* My QMX sat on the bench for nearly a week - untouched and powered off. Applied power to start troubleshooting and a very loud screeching sound erupted from the headphones - *receive audio

That's what you said last yea, Hans! LOL -- 73, Dan? NM3A

I need help troubleshooting an issue with my QMX+ 3.3v power supply board (PCB #2). After assembling my QMX+, applying power, and pressing the encoder switch, I saw 170 mA current draw but no LCD

Where would I find a description of the pinouts on the QMX board, i.e. the row of contacts on the upper right hand edge of the board? I want to measure the ADC 5V, PMW 5V etc. Trying to measure on the

A bit off topic, but I have been out of the amateur radio game for a bit and have some time this summer to dip back into it with some CW.? I've decided to take the Adam Savage approach of getting the

I always use what I got. The old NatSemi databook gave instructions on how to repurpose nearly any LM regulator chip to any voltage. I think it required a 3V drop, but don't quote me. I'll try to

Easy.... Using a TI or any other auto-tuner the same set of risks are a fact. Same for manual one! You have a IC705, use that to match the antenna if needed while employing the T1 autotuner.? Then

7809s are suitable for 9-built? QRP-Labs radios. 73, Don N2VGU

I suggest placing a resistive VSWR bridge (I have a QRP-O-Meter) between the radio and tuner.? Set to TUNE position, its 6dB loss will limit the VSWR the radio sees to under 2:1during tuning.? When
