472/500kHz Simple 10W Transverter

Описание к видео 472/500kHz Simple 10W Transverter

A very simple and inexpensive transverter designed for use with the FT817 operating in "split" mode (TX on 80m transverted down to MF and RX directly on 472 or 500kHz). It uses an IRF510 and a handful of 2N3904 transistors, a scattering of resistors and capacitors and inexpensive coils wound on 22mm plastic pipes. RX-TX switch-over is automatic and needs no relays. Results to date with a 6m vertical antenna are encouraging with WSPR reports from G, GW, F, PA and ON despite the ERP being only around 45mW.
