Hi John, I am happy for you. I should have guessed a firmware problem. It is indeed a sweet combination. Really it's a top-of-line $2,500 transceiver when all put together which can be used as a small

Thanks for sticking with me, Jim. You inspired me to keep trying! So I have figured it out. You would think that if you bought this combination from someone, they would have been using it. It is possi

Hi John, No, you do not have to connect the USB cables. I unplugged all my USB cables to the computer and changing menu 31 still changes the state of the blue "Coax..." indication below the forward po

JIm, thanks for your reply. I have changed menu 31 in the FDM-DUO to 2 antennas, but it doesn't change anything on the DUO-ART screen. I do have the cable connected from the FDM-DUO's EXT-I/O to one o

John, To change from CoaxRTX to CoaxRX+TX go to menu #31 on the FDM-DUO and change it from Antenna #1 to Antenna #2. Why? One might assume that the #2 antenna connector is for a second receive only an

Hi Heinz-Jurgen, Thanks for explaining that. I had not thought about remote control but it makes sense. Too bad it doesn't suppress this behavior if the remote feature is turned off. Maybe they will f

#duo-art

That's normal Boot up Sequence. It's needed for Remote Control to be sure, the Art and the Duo are connected. The Art is used for Remote Control and you can't press any Buttons if you are miles away a

I am using the DUO-ART amplifier with the FDM-DUO radio. The radio gets its DC power from the amplifier. When I turn the amplifier on the radio comes on, then turns off, and then turns back on again.

#duo-art

Does anyone have experience, knowledge, or ideas about how best to reduce the amount of fan noise in the amplifier? Thanks and 73, Jim AJ8S

#duo-art

I am new at this, so please bear with me. I just got an FDM-DUO and the ART amplifier. I have hooked it up as the diagram showed except for any USB cables to a computer. I can get the amp and transcei

#duo-art

Thank you. That is clear. 73, Jim

Hello Jim, you are correct, you are still using the preselector when you tune within the range of one of the enabled filters. The DUO-ART analyzes the filters settings in order and check the current f

#duo-art

I am a new DUO-ART-120 owner. I have installed seven bandpass filters in the preselector. If I set the FDM-DUO menu 31 to antenna #2 (which is necessary to use the preselector) then the receiver passe

#duo-art

The output of the FDM-DUO is very clean, one of its many virtues. The specifications for the DUO-ART 120 state that "Output Harmonic / Spurious Distortion > 50 dBc in HF band" but I do not really unde

No problem Kevin. Thanks and regards. IK2XRW. A.Ma.

Hi Alessandro, Sorry the ART has been sold to the person who had contacted me before your message. (I was waiting for confirmation before replying to you) I hope you also find what you are looking for

#duo-art

Sorry Kevin, I cannot find this option.

#duo-art

Hi Alessandro, Sorry for the delay, can you send me a PM. Thanks Kevin

#duo-art

Hi Kevin can you give me your email? Mine is ik2xrw@... Thanks.

#duo-art

Paul, Are you still looking for a DUO ART? I have a 120w with ATU that is a month old tomorrow, I'm seriously thinking about parting with it before it gets covered in dust, I'm keeping the FDM-DUO, an
