Re: Setting the spectrum/waterfall display width

george Muha <geoMtemp@...>
 

Neil (G4DBN) & Dave (W8KFJ) … Thanks you for your comments … your
taking the time to reply to my question is very much appreciated.

Additional: As I indicated in my posted question, at present I am
currently interested in gaining experience with K1JT's digital modes -
FT8, JT9, etc. The QRP transceiver feature of the ELAD along with its
convenient rear panel input of a timing rf signal seem (at least to me)
to strongly recommend this SDR for this purpose.

At the outset of working with my ELAD, I began by viewing Parts 1 & 2
of Dave's QRZ page several times. The presentation was excellent and so
smooth that after the second (repeat) viewing I was (overly) confident
that I knew how to operate the ELAD transceiver. However as I turned to
operation, I quickly became dis-imbued for the multitude of ELAD
parameters that can be varied would be overwhelming to the uninitiated.
Fortunately I am reasonably knowledgeable about SDRs – their theory and
operation - having used a Perseus for the past 3++ years for NDB DXing.

At present I am focusing on setting up of the ELAD's waterfall display
for narrow lines in an expanded spectrum width - functions of the
sampling frequency and the CW filter bandwidth parameters. I test the
efficacy of any changes in the many ELAD parameters by comparing the
waterfall pattern thereby obtained with that of a Microtelecom Perseus
SDR waterfall setup for optimized reception for a particular frequency
band. A coaxial switch permits either receiver to be connected to one
of several antennae. Perhaps a slow procedure, but for a very old man
such as me, an enjoyable and very instructive pastime.

ELAD SW2 Constant Remote Ctrl Omnirig Error

 

I'm using the SW2 together with my own Software 'RadioFrequency' (Freeware)
http://www.intrasystem.it/Frequency/Frequency.html

The Elad SD2 connection and Omnirig not yet published.


RadioFrequency is a professional software connecting to Icom Radios and the ELAD Receiver via the SerialPort and the Virtual Com-Ports:

Reading and Setting the:
------------------------
- Icom Radios Freq / Mode / S-Meter (not using Omnirig)
- Icom Radios Freq / Mode (using Omnirig)

Reading the SD2 Freq / Mode / S-Meter via Virtual Comports.


SW2 connection via Serialport to Icom Radio.
--------------------------------------------
Connect the SW2 to the Icom Radio / Software.
p.e. via COM3 it was possible. After a short time SW2 shows constant Omnirig error.

Now the ISSUE
-------------
When i started to program the Elad-Connection the SD2, using Omnirig, worked.
-CAT mode (VRX)
-RX2 (Com10)
-RadioFrequency receiving SD2 data via Com11
-Icom Radio (or else) connected to Elad SW2 (sending + receiving) via Omnirig.

Suddenly the Omnirig (Remote Ctrl) Checkbox is unchecked / not available and the Error is showing up: " Omnirig is not correctly installed ".

I would like to underline that other programs using Omnirig are working perfectly.

1. Re-Installed Omnirig + SW2 Software. No Result.
2. When Omnirig is activated with a different program, SW2 (when it is working) was reporting the same error. (Error should read "....not available".
What has "not correctly installed" to do with
"not available" which is the correct answer (when SW2 is working correctly).
Omnirig is returning precise answers via the Omnirig DLL.

The fact is that the SW2 Software is permanently showing the same Error:

" Omnirig is not correctly installed ".

I can't get rid of it.


Looking into the Windows RegEdit i can't find any data referring to SW2-Omnirig.

Re-Installing both SW2 + Omnirig > NO result.

Is there any "INIT" file or similar that could cause this issue ?

Pls. advice. Thanks for your kind attention to it.

I'm considering a Duo and haven't used wsjtx or fldigi.  Can you give a quick overview of what you have working?  Do you have waterfall, tuning, talking and listening working?  Can you encode/decode newer digital modes like olivia?  How about upgrade the firmware?

My main concern is the FDM-DUO is out, but I haven't been able to find much information about how to programmatically talk to the FDM-DUO.  Hell I've yet to find the warranty.  In any case a basic overview of what works with linux would be very useful.  Not everyone runs windows in their shack.

Re: Setting the spectrum/waterfall display width

David Kennett
 

George,

The IF window not only gives you a closer look, but better resolution.  Here's my suggestion.  Zoom in the main window to show the CW band.  Open the IF window, and zoom in pretty tight.  That way, you can click on a frequency in the main window to get close, then fine-tune using the IF window to get spot on.  You can play with the tuning steps in the software, as well as the radio itself, to make this work smoothly.  The Tuning Steps tab in the SETup menu offers a way to automatically configure this when you enter a CW band.  It is discussed a bit in Part Three of my Getting More From Your FDM DUO videos. They're are links on my QRZ page.

John: I have a company that will assist you in your quest to purchase USB cables and other cabling. Wired Communications in Scottsdale, AZ. run by Roger, KD6DNY. They are a wholesale distributor who come to lots of Hamfests, and they stand behind their products. You may give them a call at 480.209.1700. Rogers email is roger@...

Until you get all the cabling noodles out, may I suggest using your DUO barefoot? I have a lot of fun

First Post

I've been lurking for some time and finally got around to starting up my FDM Duo (I've been putting it off until I finally got a MS Windows system for the software).

I bought it used some time ago and other than initial checkout I've done little with it. It came with a BluDuo interface but I cannot get it to connect. The message is telling me the passcode is incorrect. I've tried all the standards, 0000, 1234, and 9999.

Any suggestions as to how to get this setup? It's either the bluetooth interface or, apparently, I have to go purchase 3 USB TypeA->TypeB cables which aren't cheap and no store withing 50 miles of my location has them in stock (any suggestion as to what cables are best, too?)

So far I've found the email traffic on this group very interesting and can't wait to finally start using this unit. Thanks for your help

Hi George, click on the + or - magnifying glass symbols to the right of the IF AF buttons to zoom in or out.  Max zoom in 192kHz mode is around 750Hz, that might be too much though!

Same in the IF window, but you will have to scroll a lot if you zoom right in.

Re: HC-05 Working

Mike Penkas
 

Just for info regarding programming the HC05--- I bought my HC05 on Amazon for $10.  I also bought a DSD TECH USB-TTL converter model CP2102 for $6.99.
Using this it was extremely simple to program the HC05 with a free windows configuration program located at this site
https://forum.arduino.cc/index.php?topic=431547.0
The HC05 configurator program has all the info of simple hookup between the boards and worked like a charm.

Re: HC-05'S Again

Hi Giovanni

Looks like I'm into the HC05

I had to update the pi and enable the hardware UART.
I disabled the serial console in the pi's config menu.

Do you know how long it's been since I did a loopback test... more old knowledge recovered and that checked out fine.

What was less obvious was selecting /ttyS0 instead of /ttyAMA0 to program the HC05, that discovery was kind of accidental but who cares now :>)

I did this:
*******************
AT+ORGL followed by CR and LF resets the module
the answer must be OK
AT+NAME=BLUEDUO followed by CR and LF sets the name to BLUEDUO
the answer must be OK
AT+PSWD=2357 followed by CR and LF sets the password to 2357 (if you do not do this the default password is 1234)
the answer must be OK
AT+UART=115200,0,0 followed by CR and LF sets the speed to 115200, stop bits to 1 and parity to none
the answer must be OK
****************

and got the correct OK answers, but was not able to communicate with the HC05 after that...


I now have to load BlUEDUO my android and plug the HCO5 into the DUO.

In retrospect I probably should have used a RS232 level converter and just done this on my linux box.


I will let you know how I do, thanks for the encouragement.

This sw UART is not capable to go as fast as 38400, so you be sure that you have switched the fase hw UART out of the BT.

Re: FDM-DUO for sale - Price drop....

Chet Roberts
 

The warranty is one year.
And while it does transfer to a new owner, the warranty is now expired.
The unit was purchased on August 7, 2016
I never had to use the warranty and the FDM-DUO is in Like New condition.
I think there's probably less than 20 working hours on it.....

Re: External 5V power supply for FDM-S2

Giovanni Franza
 

Hi Willi,
since S2 has a power led, you can see the led glowing when you connect the S2 to a powered USB HUB, so the power arrives from the power supply attached to the USB HUB.
I'me quite sure that, once powered from its supply, the HUB doesn't drain power from yout tablet, also you can attach mouse and keyboard to this HUB to further reduce power drain from tablet.
To be sure making mesaures there exists some USB digital power monitors available from Cina, but I haven't tested any of them.
