microHAM STATION MASTER Manual page 30

Vertical is index 1. RX4SQ is a receive only antenna and has no PA index
CW dipole is index 2, because index 1 is the vertical which can be used on 80m
SSB dipole is index 3, because indexes 1 and 2 are already used on on 80m
TX4SQ is indexes 4, 5, 6, 7 because the amplifier tunes differently in each direction.
Indexes 1, 2, 3 are already used on 80/75m band.
INV Vee is index 2, because index 1 is the vertical which can be used on 40m
3-el Yagi is index 3, because indexes 1 (vertical) and 2 (inverted V) are already used on 40m
SteppIR is index 2, because index 1 is already used for the vertical
5-el Yagi is index 3. It is usable only on 12m band where the Vertical is index 1 and SteppIR index 2
NOTE: The Acom 2000 must auto-tune each antenna on each band segment before first use. Try to
avoid changing the PA ANT NUMB indexes to avoid the need to perform the set-up process again. Even
when adding or deleting antennas, try to use a new index for any new antenna.
SteppIR: When Serial port function is set to SteppIR, Station Master controls the SteppIR using SteppIR's
native protocol.
Controlling a SteppIR antenna with SM has three advantages over controlling SteppIR by transceiver
frequency only.
Station Master adjusts the SteppIR only when that antenna is selected. This means that
●
when you jump from one band to another but you have selected the SteppIR antenna for use
on only one band (or not at all) the SteppIR elements stay on last used frequency and do not
move unnecessarily. This saves antenna wear and decreases the "ready to operate" time to
zero.
Station Master protects the antenna while elements are moving (retuning). Station Master will
●
not allow transmission when Station Master is used with microKEYER II or MK2R. With other
keyers, Station Master will prevent a power amplifier from being keyed while SteppIR is
tuning.
When operating in split frequency mode, Station Master can set the SteppIR to the transmit
●
frequency and prevent retuning between transmit and receive when operating with wide splits.
NOTE: This function does not replace the SteppIR controller, the original controller is still required.
Connecting a SteppIR controller:
Station Master's SERIAL port must be connected with the SteppIR DATA OUT port using a cross-wired ("null
modem") DB9F/DB9M cable. Only three wires are necessary, pin 2 to pin 3, pin 3 to pin 2 and pin 5 to pin 5. Do
Not connect to any other pin; doing so will cause the SteppIR Controller to operate improperly. The SteppIR
controller must be switched to the General frequency mode and baud rate for serial port in Station Master must be
same as the SteppIR controller.
