Features:
Tiny HF tunable preselector is connected in line between the antenna and your receiver or transceiver providing filtering of R.F.spectrum to reduce broadband signal energy into the receiver.
WARNING:
If the preselector is connected to a transceiver take precautions to prevent transmitting through it. An Input/Output by-pass dual power relay accessory is available to by-pass the preselector in transmission. FlexRadio user do not need external by-pass relay; see Owners Manual, Primary antenna ports configuration.
Suitable to work with any SDR or analogue radio.Tiny-CAT Digital preselector is remotely operated from a personal computer via USB over VCP by means of the USB control module option or from a radio or digital system supporting I2C bus data communication by means of the I2C bus control module option.
Operating modes:
Using the USB control module option: It works connected to a PC via USB over Virtual COM Port under Windows OS. Tuning and Band selection can be performed from:
- Its own Graphic User Interface (GUI) on PC.
- CAT protocol over Virtual Com Port (VCP), Kenwood TS-2000 protocol.
- Over the Internet or Local Network. (TCP/IP protocol).
See below Tiny-CAT Digital Preselector user manual for more details.
Using the I2C bus control module option:
From a radio or digital system supporting I2C bus remote control. On PowerSDR It works connecting the hardware to FlexWire socket on FlexRadio rear panel. Tuning and Band selection is done by means of an embedded control slider on PowerSDR under label "Heros". See below Tiny-CAT Digital Preselector user manual for more details.
