I managed to get that PuTTY to start. Audio

We had 10 folks attend the Michigan QRP Club Zoom meeting last week where the topic was keys. Pete WK8S Ed AB8DF Ernie W3ETE Stuart M0SGV Dave N8SBE Muhsin TA1MHS Rick K8MBA Jeremy KD8ZZJ TBD TA1HMG

Thanks Zhenxing. I did the installation exactly as you described, but unfortunately no activity was seen on the screen. I can try again by changing the cable and adapter, but I need to be sure of

Thank you Gary. I used it at home for a long time with a pi 3 and then a pi 4, as you described. I wanted to try my luck because it was portable and I didn't have to deal with too many devices.

I'd be more worried about my food and water supply than playing Radio Rambo. EMP precautions ended up being simplified in the end to simply disconnecting the antenna that gathers and feeds the pulse

I second that! Roy WA0YMH [email protected]> wrote:

I think that you hugely underestimate how many tubes and crystals it would take to replicate the QMX's basic radio functions, even neglecting any of the computer-control interfaces, IQ outputs, etc..

Likely the worst transient is when the relays switch over between high-Z and low-Z configuration; when this happens it is a dead open, limited only by the loss from the input connector to the

Oh, and the QMX protection is purely to cut off transmission if SWR is high, it doesn't just 'reduce' power out. It may be too late by then. Lots of other radios scale back power proportionately iin

As Zhenzing said, if you ALWAYS use the SWR Tune function when you use the auto tuner, then it's probably okay. However, make sure that the tuner won't retune randomly (the T1 won't). Also, make sure

Yes the jumper is there Martin DK3UW

Hi Everyone.? Having just successfully built a QDX, with a QMX "on the way", I have a question for Hans and the Group.? The QRP-Labs radios are all fantastic, and Hans is a certified genius.?

More likely, the SWR reading changed when you choked off the common-mode currents. > > > 73, Don N2VGU

To use an ATU on the QMX/QMX+, go into the settings on the radio, Hardware Tests, then Tune SWR. Select the band you want to use, then press TUNE button on the ATU, and then start the SWR Tune on the

I lost count of how many times its been said... QCX, QDX, QMX are incompatible with auto tuners. ALL of the auto tuners go through states of really bad match while seeking an acceptable one.? Bad

Ah! ?That would explain it. ?I definitely ordered the QLG3 option. I figured I might as well have the option just in case. :) Thank you for the response! ?I’m very excited to get started on this

There is an SWR tune function in the menu. When tuning from there, by default the output power is reduced to 25% (50% of the output voltage). The percentage is also configurable in the protection

Chuck, I've two Atlas 210Xs. The Atlas only uses two crystals (USB and LSB carrier osc)? other than 100khz calibrator. The band switch also selects the VFO frequency. Unlikek most radios the VFO

Correct me if I'm wrong but I don't believe there is any way to adjust power output on the QMX+

Hello David, Within a business day. But 7-10 days of you include the QLG3 option because we ran out and I'm waiting for 1,000 more boards that are enroute with FedEx. 73 Hans G0UPL http://qrp-labs.com
