FTdx-5000MP Receiver Block Diagram (latest release elab- by www.radiocronache.com) (Clik image to enlarge!) -
The FTdx-5000 HF/50 MHz Transceiver has a new architecture!
C
ircuit Type: VFO-A Double-conversion superheterodyne – VFO-B Triple-conversion superheterodyne – Inrmediate IF’s: VFO-A 9 MHZ/30 kHz (24 kHz for AM/FM) – VFO-B 40.455 MHz/455 kHz/30 kHz (24 kHz for AM/FM)
The Main RX (VFO A) is a two-stage down-conversion design – Yaesu engineers take the down-conversion architecture, only for Main RX A, with narrow ham-band filtering for superior close-in dynamic range. – (Like K3 Elecraft and Orion II Ten-Tec – …US made!)

ADAT ADT-200A SDR Transceiver is ready! ADT-200A Vollständig digitaler Transceiver bereit!
Funkamateur, January 2010, have published Part 1 of their review on the ADAT ADT-200 direct-sampling Transceiver, by DJ1TO. The ADT-200 truly raises the bar in overall performance; it is comparable to the rx Perseus (….excluding the Perseus instead, allows the external PC!)
La Rivista Funkamateur di Gennaio 2010, ha pubblicato la Parte-1 della Review del ADT-200A un Transceiver a Campionamento Diretto, la recenzione 1 è curata da DJ1TO.

DG8SAQ VNWA 2.5 Vector Network Analyser home-brewed from I0FTG, Pippo I0NAA, Mario I0WYC, Sil – Tow DDS oscillators are used for the RF and LO generation. The IF filter is realized through the limited frequency response of the PC soundcard used for signal analysis (typically 10 Hz to 20 kHz) in combination with digital filtering by the PC software. – See the Some more VNWA information, pictures and the Links below….>
