Note
The MFJ-826B digital SWR/Wattmeter/Frequency Counter measures up to 1500 watts. It has three high-resolution 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 auto-ranging 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 digital-analog displays make it visually easy to tune antenna tuners, amplifiers and transmitters. There are three high-resolution forward/reflected power ranges that are automatically selected: 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. The MFJ-826B 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.
