Bill, what operating system are you using? Joshua

Hey gang. Received my assembled QDX today...Thanks Mark ! OK, so the receiver is plenty hot...I'm playing on 40m first. When I attempt to transmit - either by the 'Tune' button or by actually calling

Phil, OK, now I have a clearer picture of what you are telling us.? You have a low current draw on transmit, so the power amplifier MOSFETs (BS170 Q8, 9, 10, and 11) are not drawing power.? That

Hi Charles. Mine is built for 12 volts like yours. I usually run it down at 9 or 10 volts input while doing something like WSPR (1-2 watts out) and it doesn't get very hot. I run it at 12.0 or maybe

OOps I forgot how to write a message. Is there a way to correct things?

Sorry, I misspoke, I was using a?Thruline Wattmeter, set up to measure forward power.? The QDX was connected to a dummy load through the wattmeter, and I was clicking on the 'tune' button in wsjtx

I bought one Chinese antenna tuner and soon found out that I could not install the variable capacitors and their knobs. But in my collection of an cient radio parts I found suitable ersatz.? So I

Greetings all, I've no wish to stir up the debate about which supply voltage QDXs should be built for, but in reading the manual, I saw where it says that the power slider in WSJT-X has no effect on

I am not sure I understand what you are reporting.? When you say the VSWR meter doesn't budge, do you mean when in setting the forward power mode? It also helps to know the firmware installed on the

That's not USB over Ethernet, it's USB over TIA-568 (CAT-{5,6,7}) _cable_ 73, Willie N1JBJ

I have the QDX from last December (rev 2 I think?).? Somehow I managed to show up on PSK reporter for the nearest monitoring stations on my first try, but nobody was responding to my CQ or

Tim, Your doing great. When I built my 50w amp I needed help with the troubleshooting before initial startup. Mistakes are expensive both in terms of time and replacement parts. I found a great

There have been two major component changes in the QDX over the course of its availability that may affect its power consumption. The first is the synthesizer chip. Version 1 used the Si5351A from

I believe the early version of QDX used a different chip. When it became unavailable because of world wide shortages, Hans had to change to a higher current substitute. The QDX today draws about 140ma

Looks like there are USB-over-ethernet devices that do this: https://www.amazon.com/AV-Access-Extender-Operating-Synchronously/dp/B01EV33R8S/ref=sr_1_4 You could add Wifi on both sides but that starts

The QDX requires a specific "driver(s)".? There just isn't any direct Bluetooth interface (that I know of) with this kind of driver option In order to avoid a driver, you would need to directly

Thanks Hans, not when VNCing to a headless Raspi. :(. Tried it via a direct connection to a laptop and it does as you say. Guess I will have to find how to do ‘sticky keys’ via VNC link :). 73 Ken

Don't confuse the DC input with the power dissipated in the finals. Power goes elsewhere, and (hopefully) a large fraction of that power goes out to the antenna (and does not come back). 73, Willie
