SDR Meters and Afedri

SDR Sharp v1637 Afedri SDR-LAN (Works with many SDR hardware devices)  

Below is a working folder with a beta test SDRSharp v1637 having one S-meter, Yaesu CAT control, and a Center Frequency auto correct method to solve noise spike problems seen with Afedri SDR-LAN when the operating frequency is the same as the DC Center Frequency at transmit. There is also a Spectrum Center button added. Serial controller will mute the SDRSharp receive audio when the connected Yaesu transceiver is put in transmit mode. 

Setup:
Enter Afedri LAN address - LAN must be enabled. Click gear icon at main screen. 

Serial communications:
This plugin allow SDR# to be controlled via serial (COM) interface with set of Yaesu CAT commands.

- Mutes SDR on transceiver transmit.
- Center Spectrum button.

Serial port parameters:
* Speed: 38400
* Data bits: 8
* StopBits.Two
* Parity.None

Also activate RTS Enable in transceiver menu. 

March 9 2018 - Added batch file for TenTec OMNI V+ serial control, new meter in SDRSharp1637B.zip

- The TenTec interface uses the Icom standard, would like to hear from users having Icom trying this. Close the SDR Sharp program then go the folder and look for the batch files included for changing from Yaesu to TenTec interface. TenTec is set for 9600bps. 

April 2018 - Added a fast acting digital meter, click on the S labels to change meter options. Click on A/D button to select Analog or Digital (only) meter.

SDR Sharp Virtual Meter Collection w/Afedri

SDR Sharp program using photographic S-Meter Plugins coded with Microsoft Visual Studio 2013. (C#.Net)

The following are the base meters, added as a Plug-In programmed enhancement to SDR#:

This is the unmodified levelmeter control which reads straight dB with good accuracy but its too jittery to usefor HF reception. 

This is my first modified meter, which is 2 dimensional and matches the theme of SDR# nicely. I redraw the meter face and add theprovision to decay more slowly than the attack time. I also added a calibration method to the XML file. 

Afedri SDR-NET Control Box project

The newest acquisition here is the Afedri SDR-NET SDR Receiver. The great benefit with this is ethernet (LAN) connectivity in addition to the usual USB option. The LAN offers up to 2MHZ of recordable spectrum at one time. 

Having downloaded the Open Source for the Afedri Box Software, I have the program interface coming up minimized. Clicking at the bottom of the screen brings up this widget, which allows adjustment of the RF Gain control while leaving plenty of the screen open to see the affects on the Spectrum display. I have also added these Sample Rate buttons to allow quick access to a smaller recording size that will keep the files from getting too big. When not recording, the program defaults to 1MHZ sample rate and then the SDR application (SDR#) is used to quickly zoom in on a smaller value for the Spectrum Display. Program Auto-sets the RF Gain based on BAND selected. This same widget works great with the HDSDR SDR application. 

Dragging the widget window (at left) to make it bigger reveals this, a larger display of the Afedri Command Box program. It is still much smaller than the stock version of the program, yet all of the Single Receiver functionality is still contained within. The tabs and options that do not pertain to Single Receiver mode have been removed, greatly simplifying and reducing the tab clutter. 

Simplified Command Shell tab for setting USB sample rate and making small adjustments to the Master clock.

Simplified Network Tab, this is all that is needed for a Single Receiver.
