MFJ

Digital SWR/Wattmeter W/Frequency Counter

The MFJ digital SWR/Wattmeter/Frequency Counter measures up to 1500 watts. It has three highresolution ranges with accuracy in each range from 1.8 to 54 MHz. True peak or average forward and reflected watts, SWR and frequency can be simultaneously displayed.

There are also autoranging bar meter modes to display forward and reflected power, SWR and power twin bar meters, or SWR only bar meter; SWR and forward power are also displayed numerically. PeakHold feature freezes the highest forward power displayed bar segment for one, two or three seconds. These digitalanalog displays make it visually easy to tune antenna tuners, amplifiers and transmitters.

There are three highresolution forward/reflected power ranges that are automatically selected: a QRP range (25 watts full scale), a midrange (250 watts full scale) and a highrange (1500 watts full scale). TrueActive peak reading circuit gives true peak or average power on all modes.

Builtin frequency counter gives any transmitter digital frequency readout in continuous carrier mode. Perfect for older and QRP rigs such as MFJ travel radios and MFJ QRPCubs.

The MFJ includes MFJs Amplifier Bypass Control. This exclusive MFJ feature protects your amplifier by taking your amplifier offline should the SWR increase above a userdefined preset limit. There is also a relay connector with normally open and normally closed connections that toggle when the SWR is above the same preset limit.

All information is displayed on a line character highcontrast backlit LCD display. The MFJ also includes a big lighted crossneedle SWR/wattmeter.

The MFJ enters a sleep mode when idle and when no transmit signal is present, turning off the microprocessor clock to avoid the generation of spurious signals.
