3.0.15 Converter Definition
For versions of SDR Console up to and including 3.0.15 you define a receive down-converter and a TX offset.
Define a down-converter offset for the LNB (a LNB is a downconverter), the offset is the LNB's local oscillator frequency, for example 9,750MHz. This value is selected when starting the SDR.
In the Radio Definitions window check Converter selection, then press Edit.
In the converter definitions window add a down-converter using the LO frequency of your LNB. Usually this is 9.75 GHz but it's quite common for a LNB's oscillator to vary, for example the Octagon LNB in use at G4ELI has a frequency of 9.750190 GHz (190 kHz higher than 9.75 GHz), so in the window below you would enter 9.750.190.000 .
Ideally the frequency you enter results in the Es'Hail 2 beacons being within 10kHz of their nominal frequency as this makes the beacon locking easier.
The BATC has an interesting page on their Wiki Es'hail-2 LNBs and Antennas.
Now start the SDR, selecting the new down-converter definition.
If you use a SDR for transmit (Pluto, LimeSDR) then add an offset. Note: this option is replaced in 3.0.16 with a RX/TX converter definition.
From the transmit options, add an offset which is then added to the displayed transmit frequency. For Es'hail 2 this offset is 8089.5 MHz.
