DXpatrol Up-Converter, Rx Set for QO-100 New
Antonio, CT1FFU offers both an up converter as well as a receive kit. This includes a modified LNB and a component which supplies the LNB with power and a 25 MHz clock.
DXPatrol RXSET: QO-100 LNB + Bias-T + 25 MHz reference clock source
With the QO-100 RxSet the manufacturer DXpatrol offers a modified LNB plus a power supply and a 25 MHz clock source. The LNB used to have two outputs. One of the outputs was modified to act as an input for a 25 MHZ reference local oscillator clock. This greatly improces the frequency stability, as required for narrow band signales. The output signal of the LNB is a 740 MHz after down conversion. This receive signal is fed to a suitable recceiver, for example the DXPatrol SDR.
The PLL/Bias-T component has the following functions:
- Supply of the LNB with the operationg voltage (Bias-T)
- Impedance matching from 75 Ohm (LNB) to 50 Ohm (SDR UHF receiver)
- 25 MHz oscillator clock to modified LNB
- Optional 10 MHz input for external precision clock source (GPSDO or similar)
The connectors towards the LNB are "F" sockets, the 740 MHz IF signal towards the SDR receiver is available on an SMA socket. The 10 MHz ref clock input is also an SMA socket. This reference clock input is optional, and should be supplied from a high precision 10 MHz source, for example a GPS disciplined oscillator (GPSDO) or other source. When injecting a 10 MHz reference the internal PLL is clockled by this signal instead of a quartz oscillator, the result is a much better stability and a cleaner signal due to a better signal to noise ratio.

QO-100 Up-Converter 2400 MHz
The DXpatrol QO-100 Up-Converter by CT1FFU generates a transmit signal at 2.4 GHz for the QO-100 Es'hailSat. The maximum TX power is approx. 100 mW (20 dBm), so an additional output stage is usually required (not included). The input frequency can be selected, the frequency ranges 28, 144, 432 or 1296 MHz are available. The input power should be 1 to 3 W, the absolute maximum is 6W. When using input frequencies of 144 and higher, the transmission signal is absolutely clean, the unwanted mixing products are reduced by more than 50 dB. For input of a 28 MHz signal, the manufacturer recommends the additional use of an output filter. The LO is designed as a quartz PLL with 0.5ppm stability. For particularly high requirements, an optional 10 MHz reference clock can be supplied externally. Thus the transmitter mixer is supplied with a very precise and stable clock signal. The lower phase noise of the external clock ensures an even better spectral purity of the transmit signal. The power supply of the DXpatrol Up-Copnverter is 10 to 15 V DC, the current consumption is approx. 300mA. All socket SMA.

Elad Single Band Down-Converter New
Finest RF technology by Elad, intended for satellite operation on Es'hail (Quatar Oscar 100, QO-100) and other VHF/UHF applications.
The Elad Single Band Converter converts the respective receive band to a frequency range suitable for amateur radio quipment. The use of a high-quality oscillator ensures good frequency stability. Ideal for portable applications and do-it-yourself projects, these converters are available as 5V and 12V versions. Input and output are designed in 50 OHm technology (SMA sockets), the current consumption is between 300 and 600 mA. A transformation to 75 Ohm, which might be required for a modified satellite LNB, can be done with the separately available Bias-T.
