Re: Troubleshooting Elektor SDR Shied?
Hi Herigs
This is getting concerning to me :-(
Does the test using Tera Term and the v command work ? see earlier post in this thread
What sampling rate are U using ? Use 48000 until U have got everything working. Also with W10, run MMSYS.CPL, select your input device - Recording tab -? Advanced tav - and make sure the sampling rate is also set to 48000

Re: Troubleshooting Elektor SDR Shied?
Hi Peter,
I have same issue than Henk . Only 280 release is working. When I'm using 282, no waterfall appear and no possibility to change frequency.
Le?ven. 8 janv. 2021 ¨¤?13:34, G8JCF < g8jcfsdr@...> a ¨¦crit?: Hi Henk
That is very bad news to hear re 282, has anybody else had this problem, ie 280 working but 282 not working ?

Re: FW: [g8jcfsdr] Elektor board
No problem for soldering with my Weller station! :-)
I'm really curious to see how it works, a novelty for me.
Thanks.

Hi Massimo
The UNO looks correct, and the SDR Shield is the V2.0 from Elektor
which is also correct - note U will need to solder the header pins
on the SDR Shield

Re: Troubleshooting Elektor SDR Shied?
It was not the baudrate but there was no spectrum display
i tryed al recommended solutions before finding a post where adviced was to download 280 that was in that post

Hi.
Before buying something wrong, I am attaching what I would have
chosen. What do you think?? I need your technical opinion, can I
proceed with the purchase?

Hi Massimo
Because the UK is no longer in the EU, my usual list of reliable
UK suppliers would not be optimal for you - you will need to pay
VAT, Customs duties and other taxes - so you should probably try
and find an EU supplier, I wouldn't expect to pay more than EUR 10
inc P&P for a clone UNO from an EU supplier.
I'm sure other people would be able to recommend a good EU based
supplier to you.

Re: FW: [g8jcfsdr] Elektor board
Hi.
You guys convinced me to switch to the new card! I start looking
for the best offer on the web. Any advice, not from china?
Thanks.

Hi Massimo
I use a chinese clone from eBay, very cheap, but long delivery
time, and I would think that with current Covid restrictions, post
from China might be even longer :-(
The requirements of the UNO for SDR Shield purposes is very low.

Re: FW: [g8jcfsdr] Elektor board
I am grateful to you for guiding me to understand this new world.
In the end, I think I understand. I need an Elektor module and an
Arduino module. By superimposing one another, from Pc I can
control the receiver in all its functions. Right? And the firmware
will upgrade itself, using G8JCFSDR SW.
Does it make a difference if I buy an original or non-original
arduino module? I know that the original Arduino is an Italian
product but, if I can save money, I'm sorry but happy! :-)

Re: Troubleshooting Elektor SDR Shied?
Hi Henk
That is very bad news to hear re 282, has anybody else had this problem, ie 280 working but 282 not working ?
IIRC in 280, the baudrate was automatically set inside the G8JCFSDR to 115200, whereas in 282 the operator must configure the baudrate to 115200 in the Serial I/F tab in config, could U please try that.

Re: Troubleshooting Elektor SDR Shied?
Hi Frank
Since the firmware V 1.3 has been successfully uploaded, you can use a terminal emulator, eg Tera Term, to connect to the UNO and directly send commands.
So, start up Tera Term
Set Baud Rate to 115200, 8 Data bits, 1 Stop Bit, No Parity and connect to the COM port
type
v<ENTER> The SDR Shield should respond 1.3
If U can't get this "v" command to respond then there is some really basic problem with your SDR Shield/PC Setup
if the "v" command works correctly, then U can issue the tune command, eg for BBC Radio 4 on 198 KHz
f? 198000 198000<ENTER>? should start receiving BBC Radio 4.
NB the firmware 1.3 is applicable ONLY to the G8JCFSDR, other software will require their own SDR Shield firmware, and hence will not tune the SDR Shield when the V1.3 firmware is uploaded.
Hope this helps get you going

Re: Troubleshooting Elektor SDR Shied?
Hello, my experience lately is that only version 280 works with the Elektor shield and not the newest version 282

Re: Troubleshooting Elektor SDR Shied?
An update:
Based on the magazine article linked on this page: I downloaded the VB app designed to set the Elektor SDR Shield's frequency. This app appeared to recognize the Arduino Uno when I opened the com port. The app sends commands to change frequency, but does not process the I/Q signal from the soundcard.
For that purpose, the above article gave an example using SDR# to process the I/Q. Therefore, I launched SDR# and set the input to "Baseband from Sound Card."
On the SDR# spectrum display and waterfall, I'm now seeing what looks like signals (see attached screen shot), and on the PC speaker I'm hearing what sounds like an image from an AM broadcast station.
However, the tuning does not change at all when I go to the VB app, enter a new frequency and click "set."
There is still no change from the status noted above for G8JCFSDR.

Re: Troubleshooting Elektor SDR Shied?
Hi Peter, thanks for the suggestion. "Allow desktop apps to access your microphone" is already set to "on," and G8JCFSDR Main Executable is in the list of desktop apps covered by it.

Hi Massimo
If U install the G8JCFSDR s/w on your PC, then the firmware will be downloaded to the Arduino UNO and it should just work !!

Re: Troubleshooting Elektor SDR Shied?
Hi Frank U need to enable the Microphone (I think). Do Winkey+I, Microphone, Make sure "Allow desktop apps to access your microphone" is set to ON. See /g/g8jcfsdr/topic/run_time_error_2147467259/75822182?p=,,,20,0,0,0::recentpostdate%2Fsticky,,,20,2,0,75822182 for more details 73 Peter - GM8JCf
