Re: Two USB sockets needed?

Guido Schotmans
 

Thanks very much Martin. And 2400 mA is incredible for only 7.99 Euros.  So it should also a good one for the Perseus is the voltage is stable and within the tolerance. I'll try it.

Hi Guido -

The IKEA charger is called KOPPLA and the label states max 2400mA per outlet, max total load 3400mA.

3 USB outlets, appears to be noiseless on LF (haven't checked HF, never listen up there)

Made in China of course, but bigclive.com, who is an electrical engineer who does teardowns of Chinese stuff on Youtube, has looked at these and given it a thumbs up as far as build quality is concerned, and he's a pretty reliable and thorough critic.

If you Google "ikea koppla usb power supply" you'll see it.

That's interesting ! How many Amps are these able to deliver ?

antennas on the Duo

How do you change the antenna connection on the duo from 1 to 2 or 2 to 1 in the software in the two channel mode. I am missing something when I just want to change the connection.

I am also having problems with remotectl and Omnirig Control.
FDM-SW2 is following my radio, but my radio is not following FDM-SW2.
Also Enable Split is not running correctly.

I already had a profile saved, but I saved a SECOND profile, shut down, reloaded, and selected that profile.  I could then save changes without the crashes.  When I select the first profile again, it also allows me to save changes.  100% fixed.

Re: Two USB sockets needed?

the USB charger is not noisy. Typically switching type
chargers are noisy, and linear type are quieter. Switching
type chargers are cheaper to make. That does not necessarily
mean you will pay less for them.
The biggest problem is finding linear PSU's. I think they can only be found
in shops with a large old stock.

I have to, I'll use one of those.

Hi Rich - yes, the twin USB cable is the same, one thinner than the other. I was wondering if I could do as you say if I found it necessary - I have some very quiet switched mains USB power supplies ( sold by IKEA would you believe!) and if I have to, I'll use one of those.

Thanks for confirming that I can indeed do this.

If the same Y cable is being supplied currently, one side of the Y has a thinner cable. This side is for power supply only, not data and power, which the thicker side does. You can attach the thinner side to a plug-in wall wart type of USB charger, and then the thicker side into your one available computer port. This arrangement will work fine if the USB charger is not noisy. Typically switching type chargers are noisy, and linear type are quieter. Switching type chargers are cheaper to make. That does not necessarily mean you will pay less for them. With either type, you can mitigate noise somewhat with liberal use of snap-on ferrites on all cables.

Thanks David.

I'm fortunate in being able to use the very short USB cable supplied with the receiver so that shouldn't be a problem.

All I need now is to be left alone long enough to install it - work is the curse of the hobbied classes!

Both my Elads run happily from USB2 sockets (different computers), but you
need to take care. When I changed to a new computer, the PC failed to
recognise the radio. It took a long while to find, but the answer turned out
to be a simple one. I had used a USB extension lead with many turns through
a ferrite toroid to eliminate some common mode interference, and the voltage
drop down the cable was too much. A higher quality cable got everything
running correctly.
It seems a USB2 port is fine, but you need to watch for power losses in the
cable.

Re: Two USB sockets needed?

Hihi. I think the recent mainboards are no longer as sensible as the old ones were. But the stories about killed laptop mainboards by external USB 2.0 harddrives several years ago shocked me and since that time I am careful.
Good luck

Well, if it works, it's OK. But I can remember times when motor driven external harddrives for USB 2.0 requiring 800 mA start up current burned down the mainboards. I would be careful.
BTW: My PC is about 3 years old and the S2 cannot be powered on USB 2.0. There was no damage when I tried but the S2 did not run properly. I have to use USB 3.0.

FDM-DUO SW2 Characteristics

cristorcelli@...
 

Hi All.

Been learning more and more about FDM-DUO performance. Totally impressed having owned once upon a time a FLEX 6300. DUO is a better performer, and software is more intuitive.

To the point that now my back-up rig is Yaesu FT-5000.

Notice some oddities in SW2.

At times, when commanding certain operating characteristics in SW2 (like changing from CW to SSB, or changing from SSB to CW) unexpected changes happen on FDM-DUO.

For example, a couple of times, suddenly keying SSB produce no output. I see the PTT or Foot switch cause the FDM-DUO to switch to transmit in SSB, but no power is generated. Investigating I find that Menu 32 "TX IN has changed from AUTO to MIC. If I change it back to AUTO, all works well.

Another example. When changing from CW to SSB and then changing back to CW, suddenly NO output. I use a paddle for CW, and in this case it has been working well until it suddenly fails. Investigating I find that Menu 37 has switched from paddle to key. Resetting it to paddle makes everything well again.

Anyone have similar experiences or a fix?

Franco the problem here with 1.147 is that the program never gives an error message, it just stays in an endless loop of trying to update the setting change.

Hi all,

hope for Xmas to publish new SW2 release, with some improvements.

I just want to suggest for who try to use the 1.147 release to save at least a Profile before surfing the program.
This action should prepare new environment to works as it should, and make this release more stable.

We are trying to catch what is the parameters that are not initialised, if somebody send me the given error(s) with a screenshot this may help us.

What band are you referring to? What is your noise floor level on that band? And what antenna (so we can compare)

You can power it without problems from one USB 3.0 socket.
