There is a new SDR# DDETracker plugin.

Ian Gilmour (MM6DOS) has created an add-on to the excellent SDR# program which allows DDE compatible software to control the receive frequency in SDR# Required for best results to correct for the Doppler shift when working with satellites with for example: WXTrack, SatPC32 and Orbitron.

The new version now also supports mode setting. I use this version in combination with SatPC32 and works great. Download the plugin via his website, copy two dll files and add the following to you SDRSharp.exe.Config file. (Newer SDR# version – Plugins.xml)

<add key="DDE Tracker" value="SDRSharp.DDETracker.DdeTrackingPlugin,SDRSharp.DDETracker" />

SDR# DDE Plugin: DDETracker (Version 5 beta: DDETracker V5 beta Binaries)

Update: 04-01-2014

The combination that is working for me, is SDR# Nightly build, the V5 beta binaries from Ian and SatPC32 V.12.8c. When talking to PA3GUO we found out that the current stable version (Rev 1000) isn’t working. When using SatPC32 the DDE interface is configured via the DivOptions.SQF file and I use the following settings:

- (1)
+ (2)
+ (3)
- (4)
- (5)
