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….>

Report dal 32° Congressino Microonde di Bagnara di Romagna e Relazione completa a cura di I0FTG, Pippo scaricabile in PDF file 1.28 MB. Al meeting sono interventi come relatovi diversi radioamatori esperti, come I4ZAU, I4BER, I4CVC, IK4PNJ, IV3FDO, IW6ATU il Dr Perugini e naturalmente I0FTG già citato sopra. – See the Some more information and the Links below….
FTdx-5000 Has the FCC Certificate, ID: K6620361X60, receved December 10, 2009!
That Was Fast….. will be bringing out very soon!
The Main RX (VFO A) is a two-stage down-conversion design 9 MHz first IF and 30kHz second IF . – Yaesu engineers take the down-conversion architecture with narrow ham-band filtering for superior close-in dynamic range. – (Like K3 Elecraft and Orion II Ten-Tec, see the [Note] below!)
The sub RX (VFO B) is not the same! It is a three stage Up-conversion design. The 40.455MHz first IF stage feature 3 roofing filter 15, 6, 3kHz. Each roofinf is a four-pole, monolithic crystal filter (like FT-2000, FT-950). This Sub RX uses a new subdisplay with two EL (Eltro Luminesense) to indicate Sub frequency, graphical wave and menu functions. One EL functions is dedicated at the Main RX.
[Note] Like Orion II IFs: Main Receiver IF1=9 MHz, IF2=455 kHz, IF3=14 kHz (IMD3 101 dB IP3 +24 dBm @ 5kHz) – The Sub Receiver is not the same! IF1=45 MHz, IF2=455 kHz, IF3=14 kHz (+5 dBm @ 20kHz.
