Yes, the DUO, DUOr and the S2 are excellent performers at LF... some of the best
receptions of the SAQ transmission at 17.2 kHz I have ever made, have been made
with my DUO. Also the MSF time/frequency standard of Anthorn, Scotland at 60 kHz

Hi Ken,

we have an amplifier that can be used and that I use with the FDM-DUO. Just have a look at http://rf-kit.de! Works great..

Re: AF / IF Spectrum Displays

Neil Smith G4DBN
 

I use the IF window filter edge controls and AF window EQ when trying to pull really weak SSB signals out of the noise.  Much better than using the SET dialog for the low edge.

I also like using the Marker Delta option in the IF window to measure S/N or a beacon so I don't have to change from click-to-tune in the main waterfall.  Having multiple sets of markers, one per IF windows is really useful for comparison of multiple S/N ratios at different frequencies at the same time.

Normally I want to have most of the low end in my SSB rx/tx audio, but it should be easy to adjust if other signals interferes or to hear weak signals.
NOT going into a lot of menus ! and settings. This is a very much used feature for me, learned from Power-SDR.

Michael, your experience is right and not restricted to a particular receiver. Radio amateurs usually restrict their audio to a lower limit of 100 - 250 Hz for SSB, depending on listening habits and purpose.
For transmissions it means that the power is not wasted for audio ranges that are useless for readibility, especially for DX.
When listening to broadcasts, it is also a good idea to try different settings to find out what suits your needs.

Hi Stig - if I am reading your post right, I think that you can move the lower end of the AF passband upwards (to eliminate the booming bassy sounds) by using SET -> DEMOD SETTINGS -> USB/LSB Settings and adjust the Filter Start Frequency upwards. I use 300 Hz, and it greatly clarifies the audio. This is for the S2, I have no experience with the DUO.

Re: RX differences between FDM Duo and FDM S2?

Hello Alberto,

Thursday, October 27, 2016


Thank you very much Alberto, I had no idea that a DUOr even existed
until now, I will have to look at my finances and decide if I could
perhaps run to the transceiver. Do you think it's a good choice for LF
operation?

All the best, much appreciated.

Can anyone please tell me the receiver diffrences between the FDM-Duo
transceiver and the FDM-S2 receiver? My particular interest is LF and
MF amateur transmissions, and in future VLF stuff. Is there any way
the FDM-S2 can be locked to a GPS frequency standard? Thanks.


AFAIK, the front ends of the rigs are identical... same
input filter, same ADC, same FPGA, same clock speed, so from the point of view
of the sensitivity, frequency range, dynamic range, the
two are practically identical.

The difference is that the S2 does not have the capability
to be locked to a GPS-originated 10 MHz input... so if this is an important
issue for you, my advice would be to sell (or keep...) the
S2, and buy a DUO, possibly the receive only version, the DUOr.

Re: AF / IF Spectrum Displays

Stig Rasmussen
 

Hello,

I like those windows. (If you dont understand the purpose you, dont have to use them. Hi..)

For the IF window, one of its advantages is that you can click and move the edges of your current filter. 
Also the low end of it, witch cannot be set other places. (If you like to hear all the voice-bass.)

The AF window is fine to study the audio, but useless if you havent been into that stuff before.
It also have a big BUG. If you zoom in the wanted frequency area, the X-axis is showing wrong frequencies.
I have reported this a long time ago.  (I havent tested 1.47 beta yet.)

Logging apps

I forgot to ask in my introduction:


Is anyone using a logging application with the SW2 softare? I know there is logging in the software, but I'm looking for something more. Something that will upload/download to the various sites such as eQsl, LowTW, etc.

I tried Log4OM, but couldn't get it to talk with the software.

SW2 setup for use with ERGO

Gilbert Torbeck
 

Hi, everyone.

I would like to use the Elad FDM SW2 with ERGO. I know it is possible but I cannot get them to talk to each other. The setup in  ERGO is quite straight forward and presents no problems. However, in the SW2, I am obviously doing something wrong as they are not communicating. The Elad is still quite new for me and I am not familiar with all its capabilities.

If someone is using this combination successfully, I would appreciate him or her describing the actual setup in SW2.

Thanks in advance.

Gil

Hello To The Group

engineer1@...
 

Hello To the Group,


Name is Will – N7IPY with an Amateur Extra Class.  Picked up a FDM-DUO at PacifiCon a few weeks ago.  This is my first experience with a full featured SDR Transceiver, and after a few weeks of steep learning, I have to say I kind-a like the little radio.


Station consists of the FDM-DUO driving a RM-Italy HLA-305 Amplifier to an auto-tuner at the base of a Zero-5 43-Foot Vertical.  I took my FT-1200/SB-200 Amp, and 1KW tuner and put it on a shelf for now.  I have gotten the FDMSW2 V1.147 Beta to work but it took a little time.  I run a Windows Server 2012 system in my shop and loaded a Win10-32bit Virtual client for this application.  I use a USB redirector application to provision 4 USB ports on the server to the FDM-DUO client.  The only real problem I have is that using the Server App to stream audio and basic operating controls to a remote client, the screen portion freezes but the audio keeps streaming.  This may be caused by my rather complex installation and not a big problem for me right now.


I have made up a small switch box with cabling to adapt the Mic input from the RJ-45 connector so I can use my Yaesu MD-100 Desk Mic and Heil Headset.  It has switching between Headset and amplified external speaker.  I also have PC Audio that has the best sound via the FDMSW2 application.


Last night I was able to get my BLUEDUO module working.  I had a stack of the HC-05 Bluetooth Modules in the parts drawer from a previous project and configured and soldered up the dongle.  I did not use the Pi to program the module, I used TeraTerm and a USB to Serial port dongle plugged into a Windows notebook.  For me it was a much easier set up then dragging out a Pi and getting it up and going.  Using a NuVision Solo8 Tablet running Android 6.0.1.  So far all is working well.

 

I am still trying to figure out the ‘SNAP’, ‘LOCK’, ‘->CF’, ‘Lock to CF’, and ‘Lock ABS’ functions and how to best operate the software for Ham use.


If anyone wants more details on any of the above, I would be glad to elaborate more.  Learned much from reading old posts and the information found in the Files section.
