It is entirely solid state, interfaces with the computer, does true FSK for the digital modes, and has an internal autotuner. It is capable of CW, USB, LSB, AFSK, and PSK on all of the MF and HF Amateur Radio bands. The AT-230 has three antenna connectors and a front panel switch to choose between them. This allows us to select whether or not we have the amplifier in line. The tuner is also useful for tuning the 160 meter long wire, and for tuning the tribander on the 17 meter and 12 meter bands.
Some additional accessories complete the station.
The rotor control head is nearby, allowing us to aim our triband beam and 40 meter rotatable dipole. The K-3 is the same chipset as the famous Super CMOS keyer III, a memory keyer that our members praise highly. One of the newest additions to the HF shack is a Tektronix RM-503 oscilloscope. It is a dual-trace scope with a 1 MHz bandwidth. There is a cable that connects the horizontal and vertical inputs to the back of the AEA PK-900 multimode controller.
