In a former job we used Bird slug/wattmeters on all of our RF generators - 500w-25KW. We had a box of over 100 new slugs that were off by 20-50%. We never assumed because it said Bird that is was accurate. They were checked against a calorimeter at a set frequency of 13.56MHZ at fixed power levels. I brought in my W-4 wattmeter to check the accuracy. It was surprising how accurate it was on 20M. N2TK, Tony

I stopped by to see them at their booth at a large hamfest to discuss a problem I was having with their 300 watt amp for two meters. In spite of careful tweaking and adequate drive and power supply, I could only get 240 watts output, as measured on my Bird wattmeter, I asked the MFJ "engineer" on duty if that was within normal tolerances for manufacturing for this amp. His reply was, "You can't trust those Bird wattmeters." I Quickly thanked him for his time and left. I could see no reason to waste any more of my time.
