CAT Control

SHACKLOG will interface to a wide variety of radios from Yaesu, Icom, Kenwood and TenTec. The table lists some of the radios that can be controlled by SHACKLOG. 
The radio must have a Computer Aided Transceiver (CAT) capability, and must be connected to the PC via one of the COM PORTS. SHACKLOG supports connection to COM ports 1 through 4. Some radios will require an interface to convert the COM port signal levels to TTL levels. You can purchase this from a good dealer.
SHACKLOG supports the connection of two radios simultaneously. These may be connected to separate COM ports, or, in the case of Icom/TenTec radios, both radios may be connected to a single COM port via the Icom CI-V network.
When two radios are connected, SHACKLOG considers one radio to be an HF radio, and the other to be a VHF radio. SHACKLOG selects the appropriate radio according to the band in use. The user can override this selection at any time by means of a hot key. The change-over band between HF and VHF can be set from SHACKLOG’s configuration screen.
CAT control from SHACKLOG works as follows:

After entering a callsign in order to commence logging of a new QSO, SHACKLOG reads the frequency and mode from the radio. These values are then transferred to the appropriate data fields.
By means of a hot key, SHACKLOG can force the radio to QSY to the current frequency and mode set in SHACKLOG.
At any time, changing the frequency and/or mode manually on the QSO logging screen causes the radio to QSY to the new settings.
When capturing a DX spot from the PacketCluster, SHACKLOG will QSY the radio to the frequency of the spot, and will set the radio’s mode to a value computed from the frequency according to the band plans.

SHACKLOG does NOT have a mode of operation where it continuously monitors the radio and updates the data fields in SHACKLOG as the tuning control is moved. This is not necessary and can cause unwanted QRM.
