The MFJ-869 Giant automatic SWR/Wattmeter 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 or reflected watts or SWR can be displayed on a huge lighted single-needle SWR/wattmeter.
PeakHold feature freezes the highest forward power for one, two or three seconds. These 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 (20 watts full scale), a mid-range (200 watts full scale) and a high-range (1500 watts full scale). TrueActive peak reading circuit gives true peak or average power on all modes.
The MFJ-869 includes MFJ’s Amplifier Bypass Control. This exclusive MFJ feature protects your amplifier by taking your amplifier off-line should the SWR increase above a user-defined pre-set limit. There is also a relay connector with normally open and normally closed connections that toggle when the SWR is above the same pre-set limit.
The MFJ-869 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.
