Re: SW2 Issues

Darwin Lambeth
 

Interesting. I am running out of my front headphone jack on the FDM-DUO straight to my speakers. I have all three USB cables hooked to my computer, I assumed that's all I needed cause I do have waterfall, bandscope and some other functions working. You don't need to to use mic off of computer to control the advanced settings for transmit, they work directly with the back microphone input as well. I built a custom cable for PTT and Mic Input to the back RJ45 input jack and I'm using audio gear and a footswitch for transmit.

Thanks,

Things you du in software S2 will only work on sound from the computer.
As well on TX, the advanced-TX settings only work with mic connected to computer.

Hi thanks for the reply. I'm running the following

ELAD FDM-DUO 2.7
ExtOmc_ELADFDMDUO_v1_20.dll
Windows 10 64 BIT
Quad Core Proc 8 GIGS RAM
SSD Drive

When I fire the software up, I have CAT control of some things like moving the frequency around, and transmit EQ and bandwidth settings. However when I try to adjust the bandwith IF/AF on receive nothing happens. I'm probably not doing something right, but I can't find any good documentation on how to set things up. 

What I can do:
-Change frequencies Using the Click Pad
-Adjust TX settings using (FDM-DUO) button
-View WaterFall and Bandscope
-Click on waterfall and bandscope to move around

What I cannot do:
-Adjust receive IF
-Enable Noise Blanker
Enable Auto-Notch
Enable Noise Reduction

I have all three USB cables installed to my PC, and I'm using my ouput headphone jack for receive audio hooked up to some speakers.








ELAD Thanks for the unexpected feature

Bill Nollman
 

So far 10 manual recordings have fired off without a problem. More formal scheduled testing comes in a few weeks from Las Vegas.

 

Meanwhile I love the unexpected bonus feature – when you stop playback (not pause but stop) SW2 used to revert back to the center frequency (LO) that was used to record. Now it remains on the last frequency used. This even works changing to a different file in a recording sequence and after power off/on. Studio1 has always done this and while I got used to not having this in SW2 I’m VERY happy to now have it. Way to go ELAD!!!

Auto Notch

Juan Caballero L�pez
 

The Auto Notch on the sw-2 using the fdm-s2 receiver, continue being appaling, when you use the Auto Notch, the modulations are distorted, we have talked enough on this forum about that, and there is no solution on the new software.  I don't understand how an older software like the HDSDR has a fantastic filters, Notch and auto Notch, and In the SW-2 it's so poor. And I also I don't understand if it's so dificult to improve it. 
The main diference between sdr and superhethenodyne receivers must be the Dsp and the filters, and I can understand like a not Sdr receivers can have better auto Notch than the SW-2. 


Re: SPF-08+1

Hola Rubén.

I think the SPF-08+1 is the same SPF08 with a filter to choose from the list. 
Other filters are paid separately. The SPF-08 brings no filter. 
I bought the SPF-08 with filters 20/40 / 80m.

Re: Coverage to 2m

Neil Smith G4DBN
 

Just looking at the +-32kHz spur issue and it is there even on bands below 50MHz, On 144, the main spurs are there on tx and rx as well, at +=32kHz and +=288kHz, both about -62dBc. On 28MHz, the spurs are -75dBm at +- 32kHz and a very unstable one at -80dBc +-288.8kHz. When I modulate my signal generator, the spurs at +-32kHz are modulated as well as the main signal.

At 14MHz the spurs are about the same as at 28MHz.

Can anyone else reproduce these results? I am putting -40dBm in at 14, 28, 55 and 144MHz and the spurs get worse at the higher frequencies. These are not aliasing, it looks like simple synth spurs from the LO. Do I have a fault? I haven't tried my second DUO. (yet)

Can someone try transmitting from the 0dBm port into a spectrum analyser, then try a very pure signal source at -40dBm on receive and see if you get the same spurs as I do.

-80dBc spurs at +- 32kHz are a big problem for VHF/UHF contesting, where -40dBm signals are common, and -60dBc spurs would be totally unacceptable, but perhaps on the higher bands like 13/9/6/3cm and higher, it might be perfectly OK. I'm going to see what the output looks like on 3cm, as the very good IMD of the transmission is far better than that coming out of my intermediate 28-144 transverters. Sadly, I think -1.4dBm is too little to run a Kuhne 13cm G4 transverter even if you do surgery to remove the attenuator.

Hello friends:

Soon i will buy a preselector for my S2.
I see there is a new SPF-08+1
What is this new preselector exactly?
Does it include a band?
Is by-pass included with this one?

A lot of thank's

Re: Coverage to 2m

Neil Smith G4DBN
 

Just a note of caution Jim.  On 144MHz, the 0dBm output is about -1.4dBm, but it has some rather nasty spurs at +- 32kHz at -60dBc with plain carrier.  With a two-tone audio source at about -4dBm per tone, the intermodulation distortion products are way down at -70dBc or better, looks superb.  However, I think the spurs at +-32kHz look like they are copies of the main audio, so you could end up with some unwanted signals on the UHF/SHF bands at only -60dB below the wanted signal.

Further out, there is a VERY strong alias signal on 221MHz at about -6dBm and 592MHz at -28dBm and 515MHz at -29dBm

Weirdly, I also get some quite large signals out of the 0dBm port in receive mode at 737MHz, -28dBm, another at 1.47GHz -34dBm, 2.213GHz -49dBm, 1.847GHz -54dBm and 370MHz at -60dBm, so some serious bandpass filtering is certainly needed on the transverter IF input as well as the IF output.  Those products stay there even when the DUO is transmitting.

On the receive side, the radio is not exactly sensitive on 2m, but I just turned up the RX gain on my Kuhne 13cm transverter and it works as well as with the 144-28 transverter in circuit on weak signals and it is rather better with multiple signals. Watch out for the  aliasing though.  So long as your transverters have good sharp bandpass filters at 144MHz IF with really good stopband attenuation, it should be fine running the DUO/SW2 unlocked.  The +-32kHz spurs might be a killer though.  I'm going to try with a sharp 144MHz filter and see what the transverter output looks like on 2.3GHz, 3.4GHz and 10GHz before I decide whether to use the unlocked DUO as the IF.

Measurements made using a pure two-tone audio WAV file or full CW carrier, into an HP 8562A spectrum analyser.

SW2 Issues

Darwin Lambeth
 

I can't seem to get receive parameters to change in the SW2 software, and some buttons such as Noise Blanker and Noise Filter etc.. don't work, however the waterfall and bandscope work okay. I can change the transmit EQ setting using the (FDM-DUO) button at the top of the toolbar, but adjusting receive bandwidth does not work. I can't find any docs on how to propery do this, so it may be user error on my end. Any help would greatly be appreciated.

How to report a bug ? Spotting duplicates in Spectrum display

bob b
 

        

need to report a bug.  How do we do this for the FDM-SW2 ? 


here is the issue... 


using cluster spotting network, getting multiple spots on the same frequency clogging up the display unnecessarily.  many spots right on top of each other reflecting other stations reporting the same station within the SpotBuffer aging time.


if the spotted station has moved frequency, that will be considered a new spot (possibly removing the existing? this is debatable), but certainly posting the same station on the same frequency adds no value and just corrupts the spectrum display.


would be an easy fix to change the algorithm to -


IF (a new spot comes in)
     IF spot already exists in the spot buffer (by callsign/frequency, +- some hysteresis of maybe 1-200hz)

          replace/refresh the existing spot with the new spot, refresh age to current.
     else if it is new spot
          process as normal, adding it to the FIFO SpotQ/Buffer that is aging off.


allow the hysteresis to be programmable under config/sw control. 


the entire idea is to NOT post a spot on the display UNLESS its actually a new one, don't keep putting the SAME spot on the SAME frequency on top of each other on the same display.  


how about adding some notion of age to the spotted display?  example - change colors as a % of the SpotQ max age as it ages in the Spot Buffer/Queue?

Scratch that, I understood that you wanted to use the radio with transverter to 2m.
The comment about the instructions still holds, check the two file repos.

Re: FDM DUO High VSR Alarm Timeout

Paul Marbourg
 

Thanks, Neil. That is a GREAT work around suggestion! Heck, I've even got a few Bird 50 ohm in-line attenuator pads laying around somewhere in the shack. I was hoping to minimize the gear needed to work portable by using the DUO's built in VSWR meter, but I do have a 50H slug for a Bird 43 meter or a Oak Hills Research QRP VSWR meter I could use. Just wish I had brought one along while camping in Glacier National Park last month. 
Cheers,

My homebrew QRP HF tuner has a switchable 3dB 50 ohm pad on the input
between the radio and the SWR bridge. That helps keep the SWR presented
to the DUO to a max of about 4.5:1. The pad is made with multiple
series-parallel half-watt resistors with 290 ohms to ground and 18 ohms
in series in a standard pi-network attenuator pad. I set the TUNE power
to 5 watts and that seems to work fine with no high-swr cutout.

Once I get the tuning just about OK, I switch out the pad for fine
tuning. Seems to work OK with just about any load. A 6dB pad might be
even better if your SWR bridge is sensitive enough to work OK at low power.

Hello Elad team,
could you please check, why in SW2 1_144 setting modes with two digits does not work any more.

Example:
MD001; to MD009; works!

MD0011; to MD0014; stopped working!
(I am pretty sure it worked in 1_120 or am I mistaken?)
