Interfacing with StationList

Otso Ylönen
 

Hello,
 
Have there been attempts to make SW2 and the excellent StationList to work together? StationList is a Windows application that shows a list of stations found on the frequency currently selected (databases such as FMLIST and MWLIST are the source of data). It can even "identify" an FM station if RDS PI code is available.
 
I am unaware if there is any API level availability of RDS data from SW2. Making this part of the remote control interface would be a welcome addition to FM DXers!
 
BR, Otso

Oh , I follow. The only approximation I’ve found is to open up the IF window, click the tune button and click and drag the spectrum left/right (or I use mouse scroll wheel to tune frequency also). The IF window’s spectrum latency/delay is somewhat annoying though. Probably not quite what your other software provides.

I don’t believe any of the receiver slices are independent windows or sub-windows. Also, the SW2 behaves almost like a windows modal window. A “normal” non-modal window toggles from the taskbar when you click it’s tray icon but the SW2 will not. You have to click the underscore in the upper right corner of the window to minimize it. Double clicking the window frame doesn’t do it either. A little annoying when I’m running FT8 sessions and trying to swap views.

Slice is the area or slice I listen to out of the spectrum available to me.  So, in RX1, it is the ~ 3KHz bandwidth while I am using SSB.
I would like to be able to move the slice from window edge to edge & have the radio freq move with me.  Would be so much more practical during a contest.  Can do it both in the Flex and Anan.
Thanks,
Mike N4BQQ

Re: FDM-DUO overload issues

Steve Knell
 

Maybe I'll borrow my XYL's Windows machine to see if SW2 does it also.

There is a strong signal right now on 3536 sending groups of letters S9+20.  I think the leakage is worse when the signal is clicky.  Listening in 300Hz bandwidth I can hear clicks up to 3537.

Then I can hear the high pitched artefacts of the same signal from 3537.750 to 3539.750.  Nothing 3540 and above and nothing below the actual signal on 3536.  So it looks like 1kHz to 4kHz above the actual signal.  The problem in a contest is that there are big signals every where and therefore high-pitched artefacts everywhere.  I have the ATT on and there is no PK at all.

These artefacts are only just above the noise so most people might not even notice them - I've ignored them for years now and I think that is probably the best policy..!

Hi,
I have an Elad FDM-DUO.  I am using a Heil Sound Pro 7 headset with the AD-1-iCM (No Capacitor) mic plug adaptor.  The element is iC Electret.
Could I switch to the HC-74 mic element if I also used the AD-1-iM (With Capacitor) mic plug adaptor?

are you feeding the audio in the computer and setting the audio in device? or using the mic jack?

Re: FDM-DUO overload issues

Steve Knell
 

I only use Linux in the shack so I only operate in standalone mode.  I'm guessing the filtering code in the DUO and that in SW2 may use different algorithms or there could be a bug in the standalone code.  It would make sense that this issue is only in standalone mode on CW and that combination is not that common, so that's why it hasn't been widely reported, perhaps?  What Rob describes is exactly what I get on a busy 40M band.

The problem always manifests in a contest type scenario.  So a very strong DL1ABC is on 7.020 and I can be tuning 7.025, 7.026, etc. (normally in 100Hz bandwidth "FIL 2 100") and I can hear DL1ABC squawking away in the background at a low level but completely readable.  ATT doesn't help in this scenario.  I had always put this down to some sort of ADC overload ("what can you expect for a $1000 dollars?" kind of argument) but it would be great if it's not a hardware limitation and it can be fixed in software.

It's the WPX CW contest this weekend so I know, for sure, it will be squawking away on 40M on Saturday evening.  I did download the Linux I/Q server a while back, so all I need to do is capture a few minutes of the spectrum so that it can be analysed by someone who knows what they are doing?

Hi Steve,

 

Here is the same -33 dbm signal from my Si570 signal generator, when in the LSB mode at 300 Hz bandwidth.  The audio artifacts are gone.

In the CW mode, the artifacts are there even with a bandwidth setting of 3000 Hz.

Very interesting Antony.  Rob Sherwoods' report is dated 2015.  My FDM-DUO went back to Italy last year and had all the latest firmware updates applied, so it should be up to date.  If I'm reading it correctly (you would understand this much better than me):

 "Even more strange is the leakage in the stopband. No phase noise measurement could be
  made in a 500-Hz bandwidth when tuned 2.5 kHz offset from the test signal due to filter
  leakage. Additionally, one can clearly hear high-pitched leakage out to 9.5 kHz with the
  500-Hz CW bandwidth when injecting an S9+40 dB signal (-33 dBm)."

So, you apply a single 59+40 signal to the FDM-DUO with the 500Hz filter selected and you can clearly hear that tone 9kHz away?  Something doesn't seem quite right...

That's essentially what I'm experiencing, in practice, every Wednesday evening during the CW-Ops activity hour on 40M (there is a very strong DL station who is always on!).  I thought this was related to ADC overload, but perhaps this is a separate issue.


Re: FDM-DUO overload issues

Clint Chron
 

Hi Steve,

 

Please disregard my previous email with the spectrum displays.  My HP signal generator has a lot of phase noise, so the wide bandwidths with a -33 dbm signal was the phase noise from the signal generator.

 

Here is what I see on my spectrum display with a -33 dbm CW signal from my Si570 signal generator.  I am not sure about the audio signals I see in the audio spectrum display.  Maybe that is part of the leak-through problem.  At a 9 KHz offset from the CW signal, I cannot hear any noise from the Duo.

 

 

If I go back to LSB and a 2.4 KHz bandwidth, the strange audio signals are gone.
