Example Configuration - microHAM STATION MASTER Manual

This configuration provides one example of the Router configuration process. It shows the interaction between
Station Master and Router with a moderately advanced antenna farm capable of exploiting most of the Station
Master capabilities.
Antenna farm:
160 to 10m trapped vertical
●
80m CW/SSB dipole. Dipole has a separate relay for tuning to 75m/SSB.
●
80m four square (4SQ)
●
40m Inverted V for CW usable in range 7.000 to 7.100
●
40m 3el Yagi covering whole 40m band, antenna is on rotator but offset 90 degrees CCW from SteppIR
●
20m to 6m 3el SteppIR, antenna is on rotator
●
12m 5el Yagi, antenna is on rotator but offset 90 degrees CW from SteppIR
●
160m to 40m receiving four square with preamplifiers
●
The antenna farm has eight feedlines and requires an eight port antenna switch. Two outputs are needed to
control the 80m 4SQ. Two outputs are needed to control the receive 4SQ and one sequencer output is needed
for controlling the receive preamplifier. Six additional outputs are used for controlling a six-band bandpass filter.
The Station Master is configured to support these requirements.
Outputs tab
These feedlines are connected to the antenna switch:
Port 1 – Vertical
Port 2 – 80m Dipole
Port 3 – 80m 4SQ
Port 4 – 40m Inverted V
Port 5 – 40m 3el Yagi
Port 6 – SteppIR
Port 7 – 12m 5el Yagi
Port 8 – Receiving 4SQ
The antenna switch requires 12V to select an antenna (common ground). The 80m dipole requires a source of
12V to select 75m/SSB and the receiving 4SQ requires +12V to enable the preamplifier. These functions will be
controlled by Port A – configured as voltage sourcing using internal power (default INT/SRC jumpers).
A1 – A8: microHAM Ten Switch
A9: 80m dipole relay control
A10: receive 4SQ preamp control
Band Pass filters (ICE419) requires switch closure to ground and both 4SQ antennas requires +12V to switch.
For proper BPF operation the jumpers of PORT B must be set to INT/SNK (outputs B1-B6). Outputs B7-B10
have isolated contact outputs; pins 6,7,8,9 are connected together and +12V is applied.
B1 – B6: ICE419 filter selection
B7, B8: 80m 4SQ
B9, B10: receive 4SQ
