FTRX-10 is now available at Amazon USA!

https://www.amazon.com/dp/B0FNJK4WZ3

FTRX-10 is a high impedance SDR probe for Yaesu FTDX10, and enables the radio for SDR use. In addition to its flat frequency response from 30kHz to 120MHz, the FTRX-10 has a built-in high input impedance amplifier to monitor the RX line of the radio. As contrary to conventional approaches, this m...

RadioSPECTRAL PTRX-9700 (ICOM IC-9700 Panadapter)

10/15/2020

RadioSPECTRAL PTRX-9700 Panadapter UHF band monitoring with DMR decoding for ICOM IC-9700. RF-out signal provided by PTRX-9700 is digitized by RTL-SDR and 4-FSK signal is demodulated by GQRX software. Finally audio output of GQRX is transferred to DSD+ DMR decoder via virtual soundcard. Result is clean and robust DMR AMBE+2 audio.
