Re: SDRplay and SDR sharp

anything that is a plug-in won't work. Write access to the plugin API functions is locked. Read access is mostly possible. That is: Third party plugins can readout settings but not change them. E. g. you can read the tuning frequency, but you cannot tune or set mode with third party plugins (like f...

SDR# has stopped ExtIO support a long time ago. SDR# Plugin – version 2.2 is not an ExtIO.dll, it's an SDR# frontend plugin. (With all the plugin restrictions for third party receivers in SDR#).

Re: SDRSharp Zoom FFT not working at all

You are aware that several functions in the SDR# plugin interface are locked intentionally for third party receivers which do not have the blessings of SDR#/airspy.com? The blessed reveivers are: Airspy HackRF RTL-SDRs FUNcubes pro and pro+ SoftRock RFSPACE SDR-IQ and Networked Radios All other rece...

Re: Active loop build - construction questions

I cheated and had them rolled at place nearby with a hydraulic pipe bender :) Good work. Would a simple external attenuator help if this is the case? When overload is the cause a simple attenuator right at the receiver input should of course help. I often use a simple 470 Ohm pot for test purposes....

Re: Active loop build - construction questions

Nice circle shaped loops! How did you bend the material? I never get mine perfectly round shaped. I think you should place the antenna higher above ground to get better results with the dipole. The crossed loops should deliver appr. 2.5 dB more SNR for frequencies above appr. 14 MHz. For frequencies...

They also claim this for DAB radio. In fact several DAB stations have a quality less than mp3.

Re: What's in 1.12.2 vs. 1.12?

I do not know all the changes.
One change for sure was the fix for SDRuno.EXTIO.exe which could not handle the WRPnfdc.dll in package 1.12 and terminated prematurely.
In 1.12.2 SDRuno.EXTIO.exe is working again.

Re: Active loop build - construction questions

A loop with this size should have appr. an inductance of 1.5...2.2 µH. I have a simple meter from http://www.morsex.com/aade/lcmeter.htm which does the job fine. (Unfortunately the creator of the kit has passed away.) Alternatively you could put a known capacitor in parallel to the loop and measure ...

Re: Active loop build - construction questions

The PE-Al tube is OK and a good idea. Important (for shortwaves) is big cross-section of the tube ( e. g. 1" or even more if possible). The gap at the "base" is not critical. Connect the ends of the loop and the amplifier with cables as short and thick as possible to avoid additional ...
