Re: Laptop suitable for Duo-R?

I only use it for portable contesting,  I only record audio and only use a single 192k slice so can’t comment on full bandwidth recording performance, sorry.  I keep the notebook charged with 17V from a boost converter using 12V leisure batteries, so the internal battery life isn’t too important.  I use another converter to get a steady 14V or so for the DUO, whatever the state of charge of the batteries.

Will the i5 record or just live listening? I only use i7 when recording at 6MHz. I like the Lenovo W540 which has swappable batteries for extra mobile recording time and you can swap the DVD out for a 2TB internal drive. I also like the backlit keyboard. Just bought one used on eBay for under $600. It is NOT however lightweight!

Hi Charlie, I guess this is what you are looking for? 



On the SET->Staion Memory tab, select memory source DX Cluster, then, optionally, enter the details down at the bottom left.


After saving, click on the MEM button next to SET and it should show you this form, where you can enter your favourite cluster name and DNS hostname or IP, plus port.

Now some clusters don't seem to like the telnet interface in SW2, I can't get it to work with gb7mbc.spoo.org, but it worked fine with dxc.ai9t.com and dxspots.com and a few others, so you'll need to experiment and maybe talk to the cluster sysop to see what is going wrong.  On gb7mbc, I get the login prompt, but when I try to send my call, it doesn't seem to send properly.  Might be that some need CR-LF and some need LF.

You can set a timeout and the spots slide down the spectrum as they get older.

You also get the cluster spots in the main SW2 window:


Hope that makes some sort of sense.

Laptop suitable for Duo-R?

jonathan wood
 

Hello, have just got a Duo-R and, having a mac laptop that I don't want to install windows on, plan to get a pc. Any tips on what is suitable? This one is on special: Windows 10 Hybrid Notebook v2.

I don't know much about computers or what would be useful (or useless) to connect the Elad to - any input gratefully received! (A lot of my listening is at Coastal locations in the car away from power lines so I have a bias towards the smallest device that works. I don't plan to use it for anything else, so provided that the memory can cope with the receiver, it isn't needed for anything else).

  • 10.1" Touch Screen Display

Re: FDM-DUO SW2 "Spotted station" Display

cristorcelli@...
 

Thanks Neil.

You response guided me to the solution.

I already had IN+RTS set on the DUO.

But when you indicated a "must", I looked at the settings drop-down on WSJT-X. There is also a setting for PTT, and I had it set for CAT.

I changed it to RTS, and the problem seems to have disappeared. Haven't had the problem for 3 hours of disjointed WSJT operation, so I consider it solved.

Separate matter.

In your responses I thought I saw response to my question about spot displays on SW2.

Somehow I recall you mention a memory setting, etc.

I lost the info, and I can't find it here on the reflector.

Was I drinking?

Happy New Year.

I was using 48kHz IF via VAC but I couldn't get the zooming within Skimmer to work right.  In the end I decided not to bother with it as I had been driven off the HF bands because of VDSL broadband and PLT noise making reception impossible.  Never tried 192 sorry.

Hi Charlie, under the Station Memory tab there are some settings to configure the station memory source as the DX Cluster, and cluster settings.  I don't use it much as I have the same facility in my contesting software.  It can also use CW Skimmer as a source.  I had that running for a while and it was a bit of fun, but the Skimmer interface doesn't work brilliantly with a 48kHz IF feed.

The cluster spots seemed to be OK though.  I found that on a crowded band, it was best to use Oblique orientation and shorten the timeout. Page 32 of the SW2 manual sort of explains it, just ignore the bit about CW Skimmer.  It doesn't show you the effect on the display.

2.30am here and I am still working on a particularly tricky piece of network and firewall engineering that I've been fighting with since 09:00 yesterday.  Time for bed I think, I have a meeting in six hours...

I see pictures and illustrations of FDM-DUO SW2 operation wherein stations "spotted" on the worldwide DX reflectors are displayed by their call sign above the pan scope/ waterfall display when operating SW2. The call sign is diplayed above the frequency where the station is spotted.

How is that set up?

Re: FDM-DUO SW2 "Spotted station" Display

Neil Smith G4DBN
 

The Hamlib library for the TS480 is buggy.  When using it you *MUST* set IN+RTS for PTT, not CAT.  It will fail randomly if you try to use CAT for PTT.

The way the station display works is by connecting to a DX cluster and displaying the spots.  Similar process works with CW Skimmer, except that the "cluster" connection is actually the local skimmer program.

Oblique just means slanting display.  Horizontal makes it too hard to read and vertical also.  Slanting is a good compromise.

Thanks Neil. That is a mouthful to digest.

Merry Christmas. I got busy so haven't been here much.

I too have the ability through my logging program (HRD) to see spots. But they do not display on the pan scope of SW2.

I will endeavor to spend some time looking at your info. Some of the terms are unfamiliar to me, such as "station memory source". I don't use CW skimmer yet. As to your "Obliue orientation", I am clueless.

Too Luddite.

I am also having some very curious behavior with WSJT-X. The software works, and once started it works fine for a while. Then out of nowhere it fails to transmit. An WSJT-X error window opens and asks me if I want to reconfigure the radio interface. It has a "detail" icon that when I select, it tells me there is an error in the Hamlib PTT protocol. I'm clueless what that means, and I certainly have not commanded any changes to the configuration that was working f! ine until the unexpected failure.

Hello Ron,

I am receiving SAQ too. Living in the Croatia on the south Adriatic coast. Signal was very good and only small problems with my urban area and echoes of the thundertorms over the Turkey.
Receiver is FDM-S2 and russian PA0RDT. I do not know while you have problem with antena but I am hearing Alpha stations without any problem.
Link to the extremly rare reception of the 7 Alpha stations on the six frequencies and link to thje reception of the SAQ.

Bandplan issues

Phil Williams
 

The Elad site has various bandplan .exe files that you can load. Unfortunately there is a mistake on the GB (UK) bandplan that limits the 6m band to 50 to 51Mhz. I need 51 to 52Mhz for a transverter. 

To change a band plan you need to plug a USB lead in to the CAT port, change menu #80 service to ON, run the bandplan .exe and enter your callsign and click on OPEN (not discovery) then after the AGREE page click on WRITE BAND. 

You can only change from one country to another. Although it looks like you can edit the band limits in the table  it did not work for me. 

Fortunately the NORWEGIAN bandplan has 50 to 52Mhz for 6m and the 5mhz 60m band so I loaded that and now I no longer get the OUT OF BAND notice when TX above 51Mhz.

Hello Guido,

  I tried various kind of ferrite cores, all with high permeability, and, as long as the permeability was high enough, there
were no ill effects on the ELF/VLF signals.  I never tried to go below the about 12 kHz of the Russian Alpha stations,
however.

What I use now is a FT-50-77 core, with 10 bifilar turns, twisted together before winding them. Works ok.

Something like this picture, found on Internet :



The primary and the secondary are galvanically insulated, no common connection between them.
