Specifications 

Power ranges: 
0.00 to 19.99 Watts, resolution 0.01 Watt 
20.0 to 999.9 Watts, resolution 0.1 Watt 
1000 to 2000 Watts, resolution 1 Watt 
The correct power range is auto selected. 
 
SWR range: 

1.00 : 1  to  99.9 : 1.  Above 99.9 : 1, the meter reads “infinity”. 

Frequency range: 
130 kHz to 30 MHz 
Amateur bands, 2200m, 630m, 160, 75m, 60m, 40m, 30m, 20m, 17m, 15m, 12m, 10m. 
There are individual calibration factors for every Amateur band, which are auto selected. 

 

Accuracy:  
This  is  a precision  instrument  with  48  calibration  points  and  each instrument  is  individually  calibrated  at 
the  factory.  Expect  Power  measurements  to  be  better  than  5%  over  most  of  the  power  and  frequency 
range. SWR readings are calculations based on the same input data and have similar accuracy. 
 
Modulation modes: 
CW, SSB, AM, FM, RTTY, Data modes: WSPR, FST4, JT9 etc.  SSB is auto detected and PEP measurements 
are applied where necessary. 
 
Max Power handling: 
2000 Watts for the HF bands 
500 Watts for 630m 
100 Watts for 2200m 
 
Alarm contact: 
Solid state, opto-isolated, 50 Volts max, 500mA max, not polarity conscious. 
Open resistance > 2 MOhm,  closed resistance < 0.01 Ohm 
 
Power Supply:    6 to 16 V DC, at 42mA (typical) 
 
Connectors:  Two SO239 panel mount sockets 
 
Size:    105 mm wide,    58 mm high,    140 mm deep. 
 
Weight:  410 gm
