Expert Remote System

Remote control system - Expert Remote, utilizes a client - server connection. PC with the installed ExpertRemoteServer (ExpertRS) (for MB1 users, ExpertRS should be installed on the MB1) connected
to any Expert Electronics device (one or several) used as a server.
Server’s PC connected to a router with an access to the Internet.
PC with the installed ExpertRemoteClient (ExpertRC) used as a client. Also you may use WEB-browser (HTML5) on your PC/tablet/mobile.
How it works:
ExpertRS server - software receives a high-speed stream of quadrature channels from the receiver(s), processes the signals, calculates spectrum for panorama, demodulates received signal in the RX bandwidth and sends it via local network and/or Internet to the ExpertRC client - software. Before sending the received signal, it is compressed by the server-software. Data traffic of the received signal equals 30 - 50 Kbit/s. Panorama data is also being compressed and sent to the client-software along with the received signal. Panorama data traffic equals to 30 - 950 Kbit/s. Data transfer protocol of the remote control system also includes receiver's control commands for all parameters (change frequency, modulation types, control of DSP functions, compression quality, etc.). Total Internet traffic equals 60...1000 Kbit/s and depends on the level of the signal compression and panorama quality in the client-software window

SunSDR2 PRO Update With Many Enhancements

ExpertSDR2 version 1.1.3 with many enhancements and fixes for your SunSDR2 PRO, MB1 and ColibriDDC has been released after a long period of testing. With this version remote control is also introduced for both SunSDR2 PRO and ColibriDDC.

Here are a few highlights of new features and fixes for all devices.

  • Added option to set the power and modulation meters to show peak or RMS values
  • Improved antenna and RX antenna switching
  • Rebuilt audio processor with compression threshold setting, compressor parameters now saved in profiles
  • Added new presets for the E-Coder in Panel settings
  • Added Audio Peak Filter (APF) for SSB
  • Improved CW Keying via com ports
  • Improved waterfall to display fast signals, improved rendering for less CPU load
  • Added automatic SPLIT disable when changing the frequency band or mode
  • Added global volume control to CAT
  • Improved VOX and fixed bug when switching to RX
  • Added saving RF level per mod
  • Added mixer presets for VFOA/VFOB in E-Coder panel

For detailed information and device specific updates, see the update log at the end of this posting.

Remote Control

Remote control for SunSDR2 PRO and ColibriDDC has finally arrived! The highly efficient protocol for remote control being introduced today enable you to connect and operate your SunSDR2 PRO or ColibriDDC device over almost any internet connection like ADSL broadband, mobile 3G and 4G networks, long range WiFi links etc.  The connection can be customised for bandwidths between 70 kbps to 1 Mbps per receiver including both audio and full panadapter view.

  • Remote control client for PC and HTML5 compatible web browsers including mobile browsers
  • Remote control server applications for Windows and Raspberry Pi3

Detailed update log

1.1.3 beta

General changes

  • Fixed bug frequency memory panel, incorrect sort of the stations column;
  • Stereo-RX indicator for WFM stations was added to the panorama.


  • Added stereo WFM;
  • In DSP settings was added switching of the region for WFM;
  • Fixed bug for VAC initialisation.


  • Fixed bug for VAC initialisation.


  • AddedAPF and DSE;
  • Upgraded WFM demodulator.

1.1.3 beta2

General changes

  • Fixed bug, while changing the frequency with the E-Coder panel, tuning steps were incorrect;
  • Optimized TX/RX switching;
  • Tuning step of the filter over the panorama now always equals 10 Hz;
  • With the LOCK enabled, RIT tuning is unlocked, but XIT is locked.


  • Fixed bug, voice mic rec indicator on the front panel wasn’t active;
  • Fixed bug freezing of the front panel;
  • Added VHF LNA indicator;
  • Enable VHF LNA by the long press of the ATT button on the front panel;
  • Fixed bug, keyboard backlit wasn’t active;
  • Fixed bug, lowered TX power in SSB.

1.1.3 beta3

General changes

  • In the E-Coder panel added possibility to enable APF;
  • In the power meter added pick power mode, in Options you can select wither mode (RMS or Peak): Options->Display->Indicators->Power meter.
  • Changed RX ANT functionality, in the antenna switch menu for each HF antenna input there is the RX ONLY button, now several antenna inputs could be locked for RX simultaneously;
  • Rebuilt audio compressor, added threshold slider;
  • Miscellaneous improvements and optimisation.


  • Updated ATU firmware;
  • Added ATU settings memory according to the tuned frequency;
  • ATU operating frequency from 1.8 MHz up to 30 MHz;
  • Added full functionality for the keyboard (secondary functions of the ” 0-9, “.”, ENT ” buttons);
  • Added bandscope control from the front panel
  • For the F1-F10 buttons added 4 functions: switching the RX antenna on the certain antenna connector: RX A1, RX A2, RX A3, RX A4
  • For the F1-F10 functional buttons added function enable Speaker.


Band scope control from the front panel is carried out with MULTI1 / MULTI2 / MULTI3. 

  • MULTI1 doubled knob controls adjustment of the lower and higher limits of the spectrum scope.
  • MULTI2 doubled knob controls panorama zoom and zoom center marker.
  • MULTI3 doubled knob controls bandscope central frequency.

Press and hold one of the F1-F10 functional buttons (which is assigned to enable bandscope) to enable/ disable control of the bandscope. The function could be enabled only with active bandscope. When the function is enabled, blue IND2 indicator on the front panel is active. If any local panel is active, then the knobs will either control the settings adjustments or inactive (depends on the local panel).

When all 4 antenna connectors are assigned on the F1-F10 functional buttons, they are active with inactive RX IN and vice versa.

  1. When HF band is active, all four functions are active.
  2. When VHF band is active, only two: RX A1 and RX A2 are active, because there are 2 VHF connectors.
