Re: S2 RX1 Stuck in "Lock To CW" mode #fdm-sw2 #fdm-s2

I don't remember why, I think this is due to some restriction inside the software or to synchronize OmniRig with the center frequency and not the virtual receiver frequency. I will check.

This is due to some settings. Did you enable omnirig in the Remote Ctrl tab of the Setup window ?

Subject: [EladSDR] S2 RX1 Stuck in "Lock To CW" mode #fdm-sw2 #fdm-s2

Recently bought an S2 and loaded the latest fdm-sw2 software (3.027). Impressed with both but for some reason Channel 1, Rx1 is stuck in Lock To CF mode. This is really annoying for a number of reasons.

I'm trying to determine if this a bug or if I have some hidden setting wrong. The Icon circled below is unresponsive to mouse clicks and the keyboard shortcut ("K")

Any help?

Thanks,

Re: FM DUO Heat

Vianney Colombat
 


Some comments:

Fan manufacturer code is correct, also that the airflow is from right to left when looking at the front of the FDM-DUO. There is a piece of thermal silicon between the heatsink and and the top cover to ensure better thermal conductivity.

The fan runs when the internal temperature reaches about 65°C (149°F) without delay time, if the temperature reaches the limit value of about 85°C (185°F), the writing HI TEMP appears on the display and the transmission is disabled. When the temperature goes below about 76°C (169°F) the transmission is re-enabled and the fan turns off when the temperature goes below about 58°C (136°F).

It is normal that the fan runs quite often if the FDM-DUO is almost always transmitting. Moreover the higher the ambient temperature, the more it will run.

Hi Group,

That fan with the cited manufacturer order number (manufacturer SUNON) is in my particular unit (FDM-DUO).
Since my unit left the factory some years ago, it would be quite interesting what kind of fan is being used by
ELAD in the more recently delivered FDM-DUO units (the fan in my unit seems to be an obsolete part by now).

Maybe Vianney is open and may comment on that.

Else: if you'll be going to open your DUO for the next firmware update: please check the fan manufacturer and
order number and report it back here.

I have opened my DUO again today in order to investigate that fan subject in more detail, including dismantling the fan from its mounting. Thus, some updated findings:
Opposite to my previous post, the fan in my unit does not blow air onto the heatsink, where the 2 final transistors
are fixed to. Instead, it sucks air from there. So, the airflow is from right to left, when looking at the front of the unit.
Which doesn't make things better, as it is a long way to go, until (hot) air may exit through the left side openings. 
Plus, there is the internal speaker sitting - for the most part - directly within that airflow passage.

Anyway, an interesting subject to deal with, especially when being faced with the DUOs quite tight internal layout.
I'll keep you updated about my further findings.

Klaus, DK3QN

Jeroen,

I am getting some decoding but I suspect those are the very strongest signals that I am receiving.  The signal strength graph, to the left, is only at 3-5 dbm at the bottom of the scale.  What is pavucontrol?  I did not install it but where can I find it?

Thanks for your help.

Mark,

Did you install pavucontrol?
If yes, check the audio sources under all tabs. It is very likely the wrong source is selected.
If not, do so and follow the instructions above.

And I believe there was some issue about autostarting pulseaudio. Have to dig into that too...
Currently at work, so no Pi available :-)

Re: how to record CW msg

Guy,

From what I understand, you can transmit then stand alone, but to enter then you need a computer.  Enter then as I described or enter then as part of a CAT command. 

 

The message number is set with menu 46.  The message can be sent using a long hold on F4 or F5 if the send message function has been set for those buttons with menu number 62 for F$ or 63 for F5.

 

Good luck.  From other post, I don’t know of any way to input to the message memories except by computer.

Re: DIGITAL TIMING

Craig Williams KA6RWL
 

My 2 cents. I run Digital modes on my FDM-Duo for long stretches of time with no issue. I have done this on Win 10 PC, Mac and Rpi,  so don’t think it is a common issue of the Elad hardware. The first place I would look is your usb connections. If you are running USB cables through a non powered USB hub, your probably going to have some issues. Try plugging directly to the PC and see if the problem resolves. Use a powered hub if you need the additional USB ports.

Anthony 

Older macs have a known sound issue that randomly routes audio back through the interval speakers. There is a work around by adjusting the midi bit rate that will sometimes work. This issue happens on every rig I have tried so isn’t an Elad issue but is an issue with the Mac sound card. It isn’t an issue on newer Macs since 2014.

Re: DIGITAL TIMING

Clint, I think they are talking about the USB virtual sound card within the DUO.  The sound card in my PC isn't involved in anything connected with the DUO other than driving the loudspeakers. 

One possible full solution was explained in Alberto's post, using a control loop to adjust the clocking rate to keep the buffers from growing too large or causing under-runs.  That needs development work by Elad. 

Oidar's post in that thread suggested a way to use the clock correction in VAC to set a manual compensation rate to provide a temporary workaround until the fix was done. It looks like I did that fix back several years ago. I can't recall when.

I haven't ever noticed any lagging, so I have no idea if this might help with that, but it does seem to affect the delay when using WSJT-X, at least the DT values in FT8 anyway.

I tried a test, setting the Clock correction ratio to 99.5000 and, as expected, the DT values in FT8 started to climb toward 2 seconds.  I then set it to 100.5 and it pulled the DT value back to 0.2-0.4s over a few minutes.  With it set at 100.00200, I don't see any increase in DT value that I've noticed over a few hours, but I'll leave this on 160m overnight and see if the average DT value has risen by tomorrow night.

I didn't notice any bad effects from using a silly high value of correction ratio, I would expect to see underruns and get clicks in the audio, but nothing untoward seemed to happen. YMMV

Neil G4DBN

Here is my current VAC setting for Line 1

No guarantee it will do anything useful, but it didn't seem to do any harm.

My relevant SW2 settings are:

It is probably worth raising another support ticket to keep the issue of fractional resampling fresh in the minds of Elad developers.  See the thread for Alberto's notes https://groups.io/g/EladSDR/topic/5756057 and have a read of Oidar's post about his VAC settings at  https://groups.io/g/EladSDR/message/12350

If you are using VAC, it might be worth trying a clock correction as Oidar suggested in that post, at least until the devs implement the necessary fractional resampler. If you are 2.2 seconds in 24 hours, you would need a correction of 100*(1+(2.2/86400)) = 100.002546 (or 99.997454 if it is the other way) for that VAC. That might change if the sampling clock rate in the DUO changes.

My VAC has a correction of 100.0014, I don't notice any drift on FT8 DT after 3-4 days of operation.  I've not noticed any latency or laggy controls either.  I must have set that value a few years ago.  Whether it is doing anything of benefit, I can't tell.  Perhaps I should set it back to 100.00000 to see what happens.

Re: Raspberry Pi 4 setup

Mark,

16 Gig minimal. All will do well on 8 Gig also, but for the price, get 16 or 32. Get a good quality card.
It leaves you enough room to install additional packages, such as qsstv, logbook, you name it.
And it helps reduce wear on the memory chips. Each memory cell can handle a limited number of write actions before it fails. With regular use, you probably will never reach that point, though.

If you intend to use the Pi for hamradio only, start with Raspbian with desktop, not the full version with recommended software.
