A new chat has been created: Hi, I am suffering with the QDX power on some of the bands. Perhaps you have an idea. Here is the pwr and low pass filters (LPF) per bands: 80m - 5W - OK-LPF1 60m - 5W -

I'm having a long weekend, so I'll see you next Tuesday ;-) - 73 de Andy -

Hey Guys, I am not a programmer but got it to work in the end. It really makes the QDX come alive. I hated not being able to hear what was going on with this radio. Now, you clever guys…how do I VNC

I'd translate that to "The courier had started drinking early". 8*) 73, Willie N1JBJ

doh, found i had missed the actual bit that says... 'You can find the program files for firmware revision 1.03 here ( https://www.rosenatthewheel.com/qdxsdr103.zip ) (the revision 1.04 version is in

Hello Milt I think there are some problems if the sweep goes beyond the specified band limits. However I have corrected this in a beta version that I am working on. 73 Hans G0UPL http://qrp-labs.com

Had the same problem with Parcel Force a few months ago, card was supposed to be? dropped through the door.In fact because there was no card i didn't even know who the courier was !Anyway finally got

I have made my QDX to be operated at 9V (6 x 1.5V AA battery compatible) and because my main DC in the shack is 13.8V with powerpoles I needed a little step down box. For that I used a? L78S09CV from

At one time it was advisable not to buy a car made on a Friday afternoon, now it’s don’t allow a delivery to be scheduled for a Friday afternoon! My lovely QCX+ arrived this week but it was

Don, Thanks for the heads up about the discount! While I have a Hakko 808 and their FX 888 digital soldering station I was looking for a new soldering pencil so I ordered the FX 601 along with some

I found this utube video about troubleshooting the QCX amplifier very helpful. https://www.youtube.com/watch?v=rUVLphjKaFQ -- KE4LJH Steve, Florida

Have a ver 3 QDX for sale.? Works great.? With case, wired for 12V.? Im just not too much about the digital modes. $80 Shipped contact at? ? n5mf at dfn . com Mark N5MF

Dear Hans, There are plenty of inexpensive 12VDC Regulated 2 Amp wall warts out there.?? I just use one of them and have been since QDX rev 1.??? I have had no problems at all and it makes it

Alan, Lower voltage in and lower power out both make lower heat. I see no problem in lowering risk to rig! I used 7809 bolted to case internally to keep voltage exactly right. It does run warm at 13.8

Hans, Are the frequency limits ignored during the filter sweeps? That is, can the start frequency be less than frequency min, or the maximum of the frequency sweep be greater than frequency max as set

knobs: if you have or make the right standoffs, you can use the supplied M2.5 screws and standard knobs. Conversely if you have longer screws you can make the supplied knobs work.

Dan, Hans has said he runs his at 13.8 volts as a test rig, no failures. But he recommends 12 volts to be safer. As Evan says excess voltage is dissipated as heat so that makes most feel more

The QDX manual states; If you wish to use a supply of 12 - 13 V the 3:2 winding style is more suitable and will produce 4 – 5 W output for 12 – 13 V supply. I started with the 9v build and it gave
