Discontinued MFJ-828 - Digital SWR/Wattmeter

The MFJ-828 digital SWR/Wattmeter/Frequency Counter. It has three highresolution ranges with accuracy in each range from 1.8 to 54 MHz.

There is a QRP range (25 watts full scale), a mid-range (250 watts full scale) and a high-range (1500 watts full scale). TrueActive peak reading circuit gives true peak or average power on all modes.

Built-in frequency counter gives any transmitter digital frequency readout in continuous carrier mode.

It includes MFJs Amplifier Bypass Control. This protects your amplifier by taking your amplifier off-line should the SWR increase above a user-defined pre-set limit. There is a relay connector with normally open and normally closed connections that toggle when the SWR is above the same pre-set limit.

It 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.
