Frequency can normally be adjusted in smallest steps of 5KHz or larger steps of 10KHZ, 25KHz, 50KHz or 100KHz. We

recommend you to select 100KHz as this lets you change frequency fast and there is rarely need for fine tuning. However,

you can enter this menu and select a PLL step of 5KHz for example and take advantage of these small steps.

<RF EQ>

Just leave this setting at default. It is better suited for our 100-1000W units. It is a new setting that lets you control how your

transmitter rolls off at the band edges. Several settings are available and are represented by a graphic. Default setting tries to

provide the same amount of power across the whole band.

Another setting gives a slight power boost at the band edges around 88 and 108MHz helping flatten-out the frequency

response of many RF amplifiers which tend to have lower output power and gain at the band edges.

There are additional two settings, one of these gives more power at the top of the band around 108MHz and the other does

the opposite, providing more gain at the bottom of the band around 88MHz. These four settings should cover any situation

you are likely to encounter, whatever your amplifier’s attitude might be.

This option allows you to display current LCD module firmware version. At the time of writing firmware version was

This is how you tell the exciter that you are going to use external directional coupler and power amplifier. By selecting

“External” the exciter assumes that you’ve set the J5 jumpers into external position and attached external directional couplers

or our ControlMini2 board. You can read more about ControlMini2 in the MAX PRO 3000+ manual.

You can set the sensitivity of temperature alarm here. We recommend you set these to 70-80 degrees Celsius. A properly

installed unit with a tiny fan will typically run at 55 degrees C at maximum output power. This alarm applies to externally

sensed temperature (ControlMini2), if you are using external PWR/SWR METER.

You can set the sensitivity of software driven SWR alarm here.
