Troubleshooting Elektor SDR Shied?
Hi all, I recently bought a new SDR Hands-on Kit from Elektor, but it doesn't appear to be acting normally. Below is a summary of what I've done and am seeing. If anyone has suggestions on further troubleshooting, I'd be very grateful. I have an oscilloscope if that would be helpful.
Thanks much, Frank -- Soldered the four pin-headers to the SDR shield's board, installed an antenna connector, mounted the SDR shield atop my Arduino Uno board, connected to Windows 10 PC via USB. Attached an antenna (known to work well with another SDR). Used a stereo audio cable to connect the SDR shield's output to my PC's soundcard input. -- Downloaded G8JCFSDR Build 282, installed it on the PC. Configured it to run as Administrator. Configured for the COM port, SDRModel = ElektorSDRShield, selected soundcard's in and out as per my PC. Entered other settings on the G8JCFSDR top panel per the manual. -- When I first launched the program, it advised me that the Uno firmware must be updated. It performed an update to v1.3 with no errors. -- After rebooting my PC, I launched the program and clicked to set Power = On. At this point, there is no visible activity on the top panel, and no sound from the PC's speakers. I tried tuning to known active frequencies (10 MHz for WWV, 7.074 MHz for 40-meter FT8), with no change. -- To verify that the Windows sound system is set correctly, I closed the G8JCFSDR program and launched the audio app Audacity. With the SDR shield connected, Audacity shows a low level of noise at the soundcard input. If I connect/disconnect the antenna from the SDR shield, there is a momentary jump in noise. However, there is no perceivable modulation, just a low level of random noise. -- A multimeter shows that +3.3v, +5v and gnd are reaching the SDR shield. |

Re: Elektor board
开云体育If you just want to use it as an SDR you just have to load the tuning software into the Arduino, but there are instructions in the articles. If want to do more then you might want to program the Arduino. ? Dave G4UGM ? ? From: [email protected] <[email protected]> On Behalf Of Massimo

Re: Elektor board
开云体育Massimo, ? The old board also has a USB socket and FTDI USB to Serial emulation chip which was used to set the frequency, On the new board the Arduino provides the USB interface. Its just used so the host PC can set the frequency of the SDR. ? Dave G4UGM ? ? ? From: [email protected] <[email protected]> On Behalf Of Massimo

Re: Elektor board
开云体育I asked Elektor what soldering was needed on the SDR board and they replied:- ? >It is only the headers that need to be soldered. ? So just a matter of soldering the headers that connecter to the Arduino board. The accompanying articles are now apparently free to download, but you have to register. ? Dave G4UGM ?

开云体育Hi, Massimo, ? does it necessarily have to be the “Elektor Board”? ? If not, I have a used “SAT Schneider DRT1” for sale. ? Joachim ? ?

Re: Elektor board
开云体育I would say go for the new shield. Much better sensitivity on the higher HF bands. ? Dave ? From: [email protected] <[email protected]> On Behalf Of G8JCF

"SDR Revisited" performance vs. RSP-1A
Hooked up my MLA-30 and was able to drag in WWV at 10 MHz, but very little else.? For comparison, I hooked up the RSP-1A and got excellent WWV at 5 and 15 as well, plus lots of broadcast and other stuff.
I used MLA-30 Bias-T box for the Elektor unit, but the RSP-1A provides its own feed.? That box is considered a bit noisy by some, but it may also be RF front end overload.? In any event, I can't believe that it should be that bad.? Anyone got experience / ideas? thanks so much !/mark |
