Hello Nico, after some back and forth with ATU 10 and converted ATU 100, I decided on a 4S tuner from the four States QRP Group. This small, fine manual tuner works perfectly and is fun to set up. The

Those voltages all look fine for a v1 QMX. The CPU has to be running in the bootloader to have set the PWR_HOLD signal, so it's at least partially OK. And it won't try to start up the two smps

Thanks! Sounds good. [email protected]> wrote:

Nico, I don't sell tuners HI If your tuner does not have a "tune" position, just use the "Tune SWR" tool in your QMX, that works at reduced TX power, and will put less strain on the finals. Perhaps

So the MFJ 949D would only show an swr of around 3 to the radio? [email protected]> wrote:

Nico, manual tuners normally have a "tune" position, which engages some sort of SWR bridge. When the SWR bridge in engaged, the rig sees a maximum SWR that does not exceed? between 2:1 and 3:1

I am getting myself a manual tuner soon. I was watching some videos on YouTube because I had no idea how to use them. I saw people just holding PTT even with 3+ swr. How would I do it? Just quickly

I agree with Chuck here: the more you use the rig on the air, the easier the whole zero-beating process will be for you. It's an instructive game. Alas, you don't need to literally "zero"-beat on a

I have been using Spectroid on my Android phone.? It works pretty well. An "Auto Tune" option would be nice in the QMX but in the whole scheme of new function priorities, it would be down farther on

You might consider using an audio spectrum analyzer app on your iPhone. ?I sometimes use a free app called Sonic Tools SVM to listen to my RX audio and then tune my receiver to whatever tone I

The manual and this group agree, that the QMX+ does like to see 12 V or less to have a long and prosperous live. Available here is 13.8V - as well in my shack, from battery or in the car. The small PA

Is it possible that you are over thinking things a bit? You should be able to get close enough by tuning for maximum signal loudness, with a 700 Hz'ish sounding tone. If the other guy keeps drifting

Jupiter GPS receivers are popular still for GPS locked oscillators as they have a 10kHz output They normally sell quickly on eBay if you don't intend to use it yourself for this. Andy

Any of the switched-element tuners will generate very high VSWRs as they search for a tuning solution; a manual tuner much less so. The worst is toggling the high/low Z switch, it presents an open

I let it bulge a little, it allows some slack if you need to spread turns. 73, Don N2VGU

Given the SMA connector I'd say it is simply an antenna, so passive. A receiver from 1998 is unlikely to be considered a good one given what is available nowadays. It will be slow and GPS only so not

To be clear the reason I'm thinking of getting "The Magic Eye" is that it eliminates zero beating via the sound of the tones. I have been playing a sound file of 700 Hz from my iPhone and adjusting
