Elad Italy-based repair is slow, unfortunately. Supply chain, lack of labor and covid precautions. I still love my FDM-DUO. I have two, just in case. :)

Vianney, Is this the same crystal used in the FDM-DUO transceiver? 73 - Paul - W2HRO

Neil and Klaus, I have two FDM-DUOs and have not tried to upgrade but I will try today. I use the FDM-DUOs with a transverter for EME work. Currently 432 and 1296 MHz. I will be testing a new 902 MHz

Group, I have never updated the firmware in my two (2) Elad FDM-DUOs. Are the firmware improvements significant enough that I should make the upgrade? Is the upgrade process complicated or risky? 73 -

Tim, I use the FDM-DUO as a driver for my Khune 432 & 1296 MHz transverters. - The 0 dbm output port is not adjustable. - The SW2 software will accomodate a transverter offset and display the transver

Really good price. $800 to $900 is more typical

Andy, I will not be trying to verify your findings. :) 73 - Paul - W2HRO

Can two (2) FDM-S3 output channels be phase coherent? Will the FDM-S3 output an IQ stream? 73 - Paul - W2HRO

My LoveMySwitches.com knob arrived today. See attached photo. The new knob is exactly the correct size. It has two (2) set screws and is very stable on the encoder shaft. The knob also has a very nice

Nice find! 73 - Paul - W2HRO

Any pre-distortion processing would need to happen in the FDBM-DUO. The USB path latency between the FDM-DUO and FDM-SW2 would preclude using the host PC. My guess is that pre-distortion processing ne

Neil, I'm thinking a little more about this pre-distortion feature. Since the FDM-DUO is a full duplex radio, it should be possible to to use the Ant2 port for a TX sample input and output the pre-dis

Jim, Great question! New high gain devices in solid state amp designs can push drive levels down to the 10 watts now. Even without the ART-120, the FDM-DUO can be a direct exciter for a 500w SSPA. A p

Andy, Thanks so much. 73 - Paul - W2HRO

I plan to use my FDM-DUO at 70 MHz as an IF for a transverter. In Europe will the FDM-DUO operate in the 70 MHz band? Or is 50 MHz the hardware limit? 73 - Paul - W2HRO

How do I find the PDF? 73 - Paul - W2HRO

Great work. 73 - Paul - W2HRO

I experienved the same problem with the Elad FDM-DUO after a recent Windows 10 update. To restore, I powered off the FDM-DUO, rebooted Windows 10, repowered the radio so Windows would rediscover the h

Jean-Louis, I use the FDM-DUO (28 MHz IF) and Khune transverters on 432 and 1296 MHz. I provide a 10 MHz GPSDO reference to the FDM-DUO and transverter and my long term accuracy is +/- 2 Hz. I see no

#fdm-duo

Harke, Thanks for the good news. I want to use the Duo as an IF radio for a Khune transverter. Do you also use a filter on the TX output? Should I use a bandpass filter centered at 144 MHz or a 122 MH
