Vhf/Uhf Transverter Operation - Yaesu FT-920 Operating Manual

Although the FT-920 does not have a dedicated
"Transverter" jack per se , the flexibility provided by
the multiple antenna ports and the Menu system will
generally provide easy interfacing to VHF and UHF
transverters.
The recommended interconnection points are de-
scribed below:
For transceive converters (where both trans-
mit and receive converter circuits use a com-
mon RF input/output line), connect the coaxial
cable from the transverter to the [B] antenna
jack.
For separate receive and transmit converter
units, connect the transmit converter's coaxial
cable to the [B] antenna jack, and the receive
converter's coaxial cable to the [R
jack on the rear panel of the FT-920.

provides a maximum power output of 10 Watts.
Now rotate the RF P control fully counter-

Important Note: Even though you might mis-
takenly assign a different band to Antenna B,
or forget to turn the RF P
counter-clockwise, the maximum power which
will appear at the Antenna B port will be 10
watts. If you design an input protection attenu-
ator network correctly, you should easily be
able to provide "fail-safe" protection for your
VHF/UHF transverter.
