l've had the AURORA AU-520 for over a month and NOT being able to transmit at all!!!

My set-up : FHM3 mic connected to rig and Laptop Dell PC running SmartSDR + Portable Antenna (ATAS 25 from Yeasu / 100W) (the so called Picnic tabble set up) : It does not work, the audio is so weak it can only brings 3 to 4 WATTS output with Mic gain UP and PROC...with proper MIC set up and input.

It tried wih the PC mic, same thing...
When I hit the TUNE button, I get 100 W (at 20%), and 1.15 SWR, but when I hit the MOX, I get 2 to 3 Watts of ooutput, with power slider set at 20% (100 W)

Flex support responded by a bunch of links…

Any idea? Defective Unit ?
Steel NOT TRANSMITTING... (A shame for a 10,000 dollar radio...)

    Have you checked that DAX is off? Button to right of PROC in P/CW panel.

    Is the MIC selection drop down set to MIC? (in same panel as above).

    The FlexRadio FHM-3 is an electret condenser microphone and requires voltage from the radio to function.

    • Go to Settings > Radio Setup > Phone/CW tab.
    • Ensure that BIAS is turned ON.
    • Note: If you need more drive, you can also toggle the +20 dB Mic Boost to ON in this menu.

    Is your Level meter moving at all when you speak into the microphone?

    Hi Erik,

    DAX is off, BIAS is ON, and +20dB not recommended
    FHM-3 is connected to the back panel of the AURORA (MIC and PTT), which makes NO sense to me, since I operate the radio with a PC, away from the Aurora 🙄
    MIC input / FHM-3 profile
    Audio level on meter is VERY LOW...

    Not talking about the ATU that takes forever to tune the antenna, (such a noise!!!!) and most of the time not able to fine tune.

    I have so many problems with this RIG, it's been over a month, and not being able to transmit at all !
    It looked so easy watching Mike (VA3MW) from flexradio on YouTube videos, but the reality I'm facing is totally different. I'm not a computer type of guy, and AURORA requires computer knowledge.

    I might send it back and get a normal HF Transceiver that works as soon as I turn it on.
