Ameritron RCS-12 Instruction Manual

Operation

Manual Mode

Manual mode is achieved when the MODE switch, on the front panel of the RCS-12, is in the out

position. In this mode the RCS-12 will operate with simple push-button operation. Connection of the

RCS-12 to your Amplifier Key Line will protect your station against "hot switching". Manual mode also

provides the function of letting a new antenna be selected while transmitting. The new antenna will be

switched after the transmitter is unkeyed, with a 10 ms delay to make sure a linear amplifier has time to

switch off. Do not attempt to use this function unless the Amplifier Key Line is connected to the Radio

Key In on the rear panel of the RCS-12, or else you will invoke severe damage to your station equipment

due to "hot switching." Make sure the TRANSMIT LED on the front panel of the RCS-12 is always

illuminated when transmitting.

WARNING: Severe damage to your station equipment could happen if the Amp Key Line of your

transceiver is not connected to the RADIO KEY IN jack on the rear panel of the RCS-12 – due to

"hot switching." See pages 6 & 7 for transceiver connections.

Automatic Mode

Automatic mode is achieved with the MODE switch in the in position. This mode will allow automatic

selection to a user programmable antenna . Only one antenna for each band may be selected. Automatic

antenna selection is accomplished by reading band data from the accessory port of your transceiver.

Saving Antenna Selections

In order to save an antenna selection, the radio must be connected to the RCS-12 and powered up. Set the

radio to the band you wish to set the antenna for. If an antenna has not been saved for a particular band,

the RCS-12 will sequentially light each antenna LED. Press and hold the desired antenna button for

approximately 2 seconds. The antenna's LED will light, the antenna will be selected, and saved to

memory.

Multiple antennas can be saved for the same band. Saving other antennas is as simple as pressing and

holding the antenna to be selected. If there is more than one antenna saved for a particular band the LEDs

for the antennas saved, but not selected will flash. The RCS-12 will save all selected antennas for each

band plus the last active antenna that was used on that band.

After programming all the selections for the band information that the radio can output, the RCS-12 will

automatically select the correct antenna for each band. No other action is required by the user.

Erasing Antenna Selections

To erase an antenna selection simply select the band on the radio. Press the selected antenna button for

approximately 2 seconds. The antenna LED will extinguish and the antenna LEDs will being to light

sequentially.
