I've been doing a lot of research today, just trying to figure out the interaction of frequency and mode control between the DUO and the other devices. Here's what I've noticed using the VSPE monitor,

Hi Patrick, you only get a CAT response if you send a CAT request to the USB CAT port in one of the modes where the DUO is in standalone or standalone plus 192kHz. As you suggest, SW2 does not use CAT

Thanks Neil. Two attachments - help me with their accuracy please and I'll update. I'll experiment a little on your feedback as well. Could have sworn I tried stand alone or not with same results. I'l

Howdy Neil, interesting stuff, to be sure. Well I experimented and reproduced what I thought you described. I put SW2 in direct mode with the DUO, then I changed freq. on the SW2 slider for channel RX

Hello everyone, thank you to Antony - M0IFA, Espen - LA1RQ, and Neil - G4DBN for your help with this setup guide. I've uploaded it the the following link here: https://groups.io/g/EladSDR/files/A%20Se

Thank you for posting this. I'm using my FDM-S2 in Windows 10 Parallels emulation. When I power on the radio, I don't see any ports listed at all, however the device manager screen refreshes, indicati

Hi all, I just bought a used FDM DUO and when I plugged it in last night at home, it was incredibly noisy!! I thought there was something wrong with my G5RV or with the existing settings in the transc

Hello Tom, Mine is *not* noisy at all. When yours was nice and quiet on the LiFePo: did you connect any antenna at that point? In the car: did you feed it there from the LiFePo or from the car battery

#fdm-duo

Hello everybody. Of all my devices: KX-3, Xiegu G90, ALT-512 and FT-891, the ELAD FDM-DUO has the quietest receiver. With that I can hear the whole evening on my monitor speakers on the shortwave, wit

#fdm-duo

No they are not like that Tom. I use mine for extreme weak signal work on VHF/UHF/SHF and on LF and it is one of the best performers I have ever used. Hard to say what is wrong though. The DUO is extr

#fdm-duo

You might want to check your AGC thresh-hold setting. If it is all way to the right, the radio will be very noisy. All the way to the left and the radio will be extremely quite. 73 Clint W7KEC

Thanks for the replies so far - it's very much appreciated! I will try out some of the suggestions when I get home from work. The FDM DUO was purchased for use in the shack where a Yaesu FT-DX3000 and

#fdm-duo

Have you tried your LiPo battery in the shack to rule out noise from your power supply? I will ditto that of my radios the Duo is very quiet. Craig KA6RWL

#fdm-duo

Don’t think I can help as traded in my ICOM 7300 to get an ELAD DUO-ART 120, because I found FDM-DUO’s Rx was much quieter than the 7300’s! As before, running with no RF ground - my current antennae a

#fdm-duo

Okay, so I'm home and have tried the suggestions. Here's the answer to your comprehensive help Neil... What level in dBm does the display show with no antenna connected and with it connected? -120dBm

#fdm-duo

Tom, It makes no difference drawing the DUO power from the ART-120, as long as the power supply to the ART-120 is the same as before (same power source, the DC power feed-through to your DUO will cert

#fdm-duo

Tom, What also came to my mind: do you have any sort of non-HAM or HAM transmitter close to your location? Opposite to your other transceivers, a 'standard' DUO has a wide-open frontend in order to al

#fdm-duo

Hi Klaus, I have no HAM/CB operators nearby. As for my shack's 240V, it all runs through one socket which goes through this home-made FILTER.

#fdm-duo

You don’t have a Band II (88-108 MHz) transmitter nearby do you? I connected a renowned person-amp to my S2 and Holme Moss 8 miles away caused all sorts of problems 73 M0OSA

Yes, I live 1 mile away from WINTER HILL transmitter, but it causes me no problems on any other radio. I ripped out the shack last night to have a big tidy-up, so when it's all back together, I'll do
