Harold,
Further to your posting concerning the 5 kW dummyload from Palstar I have
checked the VSWR on 80 and 20 meters and could not find anything unusual. I
measured under the following conditions:
Input 1500 w carrier
Frequency 3600 kHz
VSWR 1 : 1.2
Input 1500 watt carrier
Frequency 14200 kHz
VSWR 1 : 1.1
SWR meter: Diamond SX-100, specified accuracy +- 5-10%
Cheers, Dick
