## Overview

The Bullseye QO-100 TCXO LNB is a top-tier Ku-band down converter engineered for professionals demanding ultra-stable frequency performance. Calibrated to within 1 kHz using GPS-locked analyzers and maintaining ±10 kHz stability outdoors, it outperforms pricier VSAT LNBFs. Featuring dual-band output and a unique 25 MHz TCXO reference port, it empowers advanced users to monitor and correct frequency drift, making it the go-to choice for serious ham radio and satellite enthusiasts.

## Description

The Bullseye LNB is the world's most precise and stable DTH/consumer Ku-band down converter. Even a VSAT LNBF costing hundreds of dollars more is no match for the performance of the Bullseye 10K LNB. Each unit is calibrated at the factory to within 1 kHz of absolute precision against a GPS-locked spectrum analyzer. Under outdoor conditions, the stability of the LNB is well within 10 kHz of offset. As a bonus feature, the Bullseye 10K provides access to its internal 25 MHz TCXO through the secondary F-connector. This reference output can be used to directly monitor the performance of the TCXO over time. Features - Bullseye 10 kHz BE01 - Universal Single Output LNB - Frequency Stability within 10 kHz in Normal Outdoor Environment - Phase Locked Loop w/ 2 PPM TCXO - Factory Calibration within 1 kHz Utilizing GPS-Locked Spectrum Analyzers - Ultra High Precision PLL Employing Proprietary Frequency Control System - Digitally Controlled Carrier Offset w/ Optional Programmer - 25 MHz Output Reference Available on Secondary F-Connector (Red) Specifications - Input Frequency: 10489 - 12750 MHz - LO Frequency 9750/10600 MHz - LO Frequency Stability at 23C: +/- 10 kHz - LO Frequency Stability -20 - 60C: +/- 30 kHz - Gain: 50 - 66 dB - Output Frequency: 739 - 1950 MHz (Low Band) and 1100 - 2150 (High Band) - Return Loss of 8 dB (739 - 1950 MHz) and 10 dB (1100 - 2150 MHz) - Noise Figure: 0.5 dB

Review: Nice product, fairly stable - I use this for ham radio reception on 10GHz. I can pick up Qo-100 with it OK and the drift is adequate for decoding SSB signals though it does require some retuning of the SDR as time goes by because the LNB is not 100% stable.
Review: Impresive stability - I bought this specifically for reception of QO-100 and so far am extremely impressed with the frequency accuracy and the stability (lack of drift). I replaced a "normal" PLL LNB and although the sensitivity is no better, the stability when the temperature fluctuates, seems much better. The additional 25MHz oscillator output could also be useful in correcting drift, though I haven't needed to try that yet. Not cheap but I reckon it's a worthwhile improvement.

### ⭐⭐⭐⭐⭐ Nice product, fairly stable

### ⭐⭐⭐⭐⭐ Impresive stability

### ⭐⭐⭐⭐⭐ One of the best LNBa on the market
*by G***Z on 18 October 2021*

The application here is for the amateur radio satellite OSCAR –100 (Orbiting Satellite Carrying Amateur Radio) and roe receiving 3cm amateur radio & television repeaters. This LNB is known to have a super stable local oscillator. Additionally this one has been modified to allow a 25MHz external reference from the GPS locked oscillator to be applied, so it’s absolutely ideal for narrow-band satellite operations. For those without technical knowledge and do not understand the above comments, this LNB is not suitable for SkyQ or standard sky box which has a recording feature, it’s designed for the amateur radio and professional broadcast/radio community use. 73 de G8YTZ
