Transverter system originally designed for use with the FT-901 but modified to work with my FT-One.
The modification required was to the input drive circuit as it is expecting a signal from the FT-901 which is at a much higher level than that output from the FT-One.
It is also a tad deaf so the use of the preamp on my BNOS 100W 2M liner is needed. I have not looked into the reason behind this yet, but given some free time I do intend to.
