Topband: QRP and Bird 43 Watt meter help

[Jim WA9YSD]

Any one out there using a Bird 43 for measuring out put power for QRP?
I have a 250H element for HF.  Should I get the 50H element for HF?
I have a Ten-Tec Omni VI Plus Power turned down to minimum. with the 250H slug I measure 5 watts, first mark from the bottom of scale.  Not very accurate or is it?
There are lower wattage slugs but for a much higher frequency range.
The 250H range is 2 to 30 mhz 160M is not quite covered but I think is ok.

Stay on course, fight a good fight, and keep the faith.    Jim K9TF/WA9YSD
