That would be the really hard way to go.? Little things like the TR switching is not adequate for 100W without modification. When amps are combined that is done at the core amp module level? then

Hi G.eorge I believe the U4B requires 5v from the usb cable to get the terminal program to start automatically. I would carefully check the pcb on the U4B to make sure you see 5v upstream of the

Hi, Wondering if anyone has tinkered with idea of combining 2 of the 50watt qcx amps using RF combiners Thx AA6ST

QMX +, new build, all bands except 6 meters, receive and transmit, but not 6 meters.? Transmit on 6 puts out about 25 MW, about a 1/4 of a watt, but draws same DC amps as on other bands, about 1.2

Hi George If you have the right cable we got QDXs, QMXs work with no problem. I don't see why it shouldn't work 73 DE muhsin TA1MHS ps. Spy stuff eh?

Primarily for fun it seems an AM mode would be simple to incorporate and a stepping stone to SSB.? I know this would be limited to 2W.

Greeting QRP-LABS fans! i Am trying something i have not see of or heard elsewhere... i Am trying to connect the U4B balloon tracker to an Andeoid device using an OTG connection and running the

A new chat has been created: During the COVID lock downs we had down under, I built two QCX which both fired up first go without any issues other than tweaking the toroids to see if I could get a

Eric, Beautiful build job. Especially the print on the face plate and the antenna ports on the top. i have purchased two built ZM2 AMUs and didn’t like the way they were constructed so rebuilt them

I should have mentioned that i have also used an ATU-100 with that same EFRW + 9:1. It's nice to just push a button to tune, but I get lower VSWRs with the manual tuners.

Mike, Tony, I have had very similar experience with my QLG1 (x2) and QLG2 (x2). The QLG1's patch antenna definitely seems better. However, I have not tried it with the QLG2's antenna on a

John, You were able to leave...I'm jealous. When you "transmit" with the rig, is it actually making any meaningful output power, or is it just spewing low-level noise? If it's still making power, I'd

Hi Tom, welcome to the magic smoke & BS170 replacement club ;-). Have fun with your QMX vy 73 from the black forest Matt DL5MAY --

I’m using a mag loop with my QMX, so tuning by noise and finishing with the analyser. So far so good !

Hi? I have both nanoVNA and simple SWR meter up to 80W. But my ready to go kit has very small SWR/PWR meter. I usually use resonant antennas and only need nenoVNA during antenna construction and

For what it's worth, the wiring and the connector used for the QMX external microphone is identical to that of the tr(u)SDX, so if you happen to have both rigs, you'll be able to use the same external

Hi Bill, sorry, but I have to disagree. This is the usual first step of phasing out of old designs. Consider new product -> not recommended for new design -> obsolete -> not available anymore As

Dirk, this is from the TI site ... it shows the company is not recommending it for new projects.? Note the very last sentence. To me, that reads as a no-confidence vote going forward. ** PCM1804

After learning how to properly wire the microphone for the QMX, I went through my collection of surplus microphones and found this realistic microphone that was for a RadioShack HTX202 that I no
