CAT
This link is highly recommended
.
Thanks to this link the linear amplifier will detect, while in receive mode, the
operating frequency of the transceiver and then automatically control
changes of band, antenna and automatic antenna tuner. Most modern
transceivers have CAT control. In old models often, analog or digital
information are sent for changing band. The SPE Expert 2K-FA, thanks to an
efficient frequency counter, constantly controls and verifies data coming from
the transceiver. Automatic management of bands, antennas and tuner can be
done in the following way:
a)
In all recent transceivers through CAT connection
(HIGHLY RECOMMENDED).
b)
In the YAESU models not listed, or without CAT, through "BAND
DATA".
c)
Configurations a) and b) are recommended. In older radios which
do not have CAT or BAND DATA through the internal frequency
counter.
Note: in case c) the CAT link with the transceiver is not needed because the
frequency is detected from the transmitted signal.
FOR THIS REASON, BECAUSE OF THE HIGH POWER IN USE, IN
ORDER TO NOT DAMAGE THE LINEAR, WE STRONGLY
RECOMMEND YOU CHANGE BAND WITH THE LINEAR IN STANDBY
MODE.
USE THE CONDITION c) ONLY IF CONDITIONS a) OR b) ARE
IMPRATICABLE.
Note: in some transceivers the “RELAY” and “CAT” signals are activated by
menu selection: refer in this case to their
user’s manuals..
