Re: SW2 problem

Tony EI8JK
 

OK it gets stranger, but might help in pinpointing the problem.
If I connect with my DUO it works perfectly and it also works perfectly with my S1, but crashes every time when I try with the S3.
I would have thought that if it works with one it would work with them all, but apparently not so.

The problem I have is, if I start SW2 with the S3 turned off it will start OK in offline mode.
If I try to start SW2 with the S3 turned on it hangs at ....Loading...
If I click the loading panel Windows reports that SW2 is not responding.

I've looked at past posts with this sort of problem and have tried; uninstalling SW2, deleting all files with "ELAD" in the title, deleting recycle bin, rebooting, and then reinstalling SW2, to no avail.
Any idea what to look for or more importantly, how to fix it?
Thanks, Tony.

I did follow up with a OOPS e=mail about the F5 button first.  😊.   Look into the CAT function (DF).  It is supposed to set the radio back to default (I think).  Also there is a long press function

For F5.  If it works then the button probably is OK.

When all else fails, have you tried a RESET?  The instructions are in the manual section 4.2.  Best of luck, I hope that fixes it.  The other failure I can see is a F5 button failure.

Oops that reset requires the E5 button press.  I guess I should have read the procedure before I answered the question the first time.  Sorry.

All my tests were also performed stand alone.
What I see is the not the same thing than Neil (Neil's looks even more interesting!). The "spurs" follow the main signal when moving frequency.
For Klaus : the "spurs" are also there on PWR output in AM/SSB only (same than 0dBm output). I do not see them on the 28MHz output of the ICOM7400.
I will try to update the software versions especially the TX one.

Re: FDM-Duo spurious

Neil Smith G4DBN
 

Well that's interesting.  Using the 8562A there is no sign of the odd products at +- 48kHz, but they are *definitely*there on the E4406A.  However, looking at a much finer resolution, I see that the products vary according to the tone frequency (or whistle) that I use to modulate the SSB, and are inversely proportional to a harmonic of the original tone, dropping fast in frequency as I raise the frequency fo the modulating tone.  It looks like they are a figment of the E4406A's FFT processor imagination.  That is unusual, as normally it has much better performance than the old 8562 clunker. It isn't anywhere close to overload. 

Using a 0dBm signal from an HP E4421B, there is no sign of the odd products down to -95dBc.  I suspected that what I was seeing was aliasing of some of the other products from the DAC. 

I tried it through a 70 MHz LPF but the products were still there at the same level on the E4406A at around -65 dBc. Definitely nothing on the analogue spectrum analyser, and nothing on the E4406A with a tone from the signal generator at ther same level and frequency as from the DUO.

Looking on the 8562A, I see nothing other than a tiny amount of the second harmonic of the 28 MHz signal, so what is the difference between a pure tone from the signal generator and an SSB tone from the DUO that causes these odd products to appear?  I'll try it with a pure tone from Audacity fed into the DUO from the PC when I get a chance.

I'll have to investigate further to see what is going on. A cautionary tale about whether you can trust your instruments.

My tests were standalone, no software running, but I didn't disconnect the USB leads.  I'll check again using the HP8562A as well as the E4406A and see if disconnecting the USB leads has any effect.

Maybe I am overfocusing on it... I had a problem previously with the PWM supply of the drivers's fan with spurs at 20 kHz 10 dB strongers than the +-48 and my neighbour could hear them very easily. He did not complain about my intermodulation products (yet).

Re: #FDM-DU spurious #fdm-du

Chris Bartram
 

Hello Jean Louis,

While I applaud any attempts to make spurious transmit products as small as possible, we'd have to either use more complex, and expensive digital technology to do that or to move back to crystal controlled transmitters ...  :-) While I agree with your analysis, -90dBc discrete spurious signal suppression is a very difficult challenge indeed! It's worth looking at the relevant ETSI specifications

I had discussions with the RSGB Contest and VHF Committees at about the time they came-up with that figure. I think it has been retained as a target, but it would be difficult to enforce that as a requirement - even professionally.

Although I'm not really active on the VHF bands nowadays, I do listen, and many signals from the UK - including serious operators - do not seem to meet that challenge. When I'm ready to come back on the air (I am currently involved in a major design/build project on the higher microwave bands)  I'll look carefully at my own system. There are some stations who who approach the -90dB target, but most operators do not understand how to drive a basic transceiver, let alone produce a clean signal ... Now don't get me onto the subject of badly set-up commercial 'linear' amplifiers!!

Living in IO70, I do hear some very good signals from France on 2m!

Andy,

First I don't see spurs like this on other TX (and your Duo does not behave like mine).

Second if I am not mistaking :
- I have neighbours 20km away in line of sight.
- I want to use +57 dBm power with spurious at -80 dBc
- I assume 13 dBi antennas on both sides.
- The line of sight attenuation for 20 km is around 100dB
- The spurs at my neighbour's RX input will be :  57 +13 -100 + 13 - 80 = -97 dBm which will be well above his noise level.
If I transmit 48 kHz above him receiving a weak signal at -120/-130 dBm or less in FT8, I think he won't appreciate my Txing.
I quote the VHF/UHF cook Book there : " the RSGB VHF contest Code of Conduct calls for spurious products to be suppressed to -90dB"
The REF might not have such Code of Conduct... but I think you have good practises over there.
