FAQ for FTRX-10

Q: What is FTRX-10?
Answer: FTRX-10 is a type of panadapter that lets you probe the RX scope line of Yaesu FTdx10 without any loss, and analyze a wide range of spectral window for SDR applications.

Q: Is installation of FTRX-10 reversible? Do I need to use a solder station?
Answer: Installation of FTRX-10 is totally reversible which means that you can uninstall the unit at any time without modifying your Yaesu FTdx10.  Shortly, you do not need any equipment other than a screw driver.

Q: How can I buy it?
Answer: Simply by clicking the BUY button above.

Q: Where is it going to be shipped?
Answer: The United States, The United Kingdom (ML&S).

Q: Why should I use FTRX-10, Yaesu FTdx10 already has DVI(video) output?
Answer: The FTRX-10 provides an analog RF output (a direct copy of the received signal), enabling connection to an external SDR receiver (e.g., SDRplay). This allows you to take advantage of higher dynamic range and significantly wider spectrum coverage than the FTdx10 alone can provide.
Key advantages:
1- No need for an additional monitor—your existing PC monitor can display the spectrum, saving space in the shack.
2- Monitor or listen to multiple frequencies simultaneously while the FTdx10 is tuned to a specific channel.
3- Apply advanced or custom demodulation techniques through SDR software, beyond what the FTdx10 supports.
4- Observe a much wider spectral window (e.g., up to 10 MHz with SDRplay) instead of being limited to 1 MHz.

Q: How does FTRX-10 work?
Answer: FTRX-10 utilizes a wide bandwidth, highly linear, and high input impedance amplifier to probe the RX scope line of Yaesu FTdx10.  High impedance probing is crucial to acquire the RX scope signal from Yaesu FTdx10 without any attenuation.

Q: There are already some panadapters. What makes FTRX-10 special so I would use with my radio?
Answer: Conventional panadapter implementations typically require soldering and the use of relatively long tapping cables, which not only voids the radio’s warranty but also increases signal attenuation and distortion due to cable parasitics. The FTRX-10 solves these limitations by utilizing a highly linear, wideband current-feedback op-amp topology, thereby preserving maximum signal-to-noise ratio (SNR). In contrast, alternative designs often rely on FET-based buffering stages, which introduce additional distortion as a result of the transistors’ nonlinear transfer characteristics.

Q: How can I make sure FTRX-10 works as intended?
Answer: We are using frequency sweep method to simulate the Yaesu FTdx10 RX scope signal. Our sweep characteristics ranges from 30kHz to 120MHz @980mVpp as a sinusoidal signal.

Q: Am I going to see any signal during TX?
Answer: No.  FTRX-10 only taps the RX scope line of the radio.

Q: Is there any warranty for the product?
Answer: Yes, we provide one year limited warranty. The customer is responsible for shipping costs.
