It appears that the minimum power output of my 7800 is 3 watts, which is fine as I'm not interested in running less than 5 watts. Not surprisingly, the power output meter on the 7800 appears to be inaccurate at such low power settings. 5 watts output as measured by the OHR WM-2 QRP wattmeter into a dummy load does not illuminate any power output level bars on the 7800. However, 10 watts output measured on the WM-2 correlates with 10 watts indicated on the 7800's meter. Of course the WM-2 itself may be a little inaccurate. And as is stated in the manual, the 7800's auto antenna tuner will not work at power levels less than 8 watts on HF. I have one of the 7800's antenna ports dedicated to QRP operation and have the QRP wattmeter in line with that output, leading to a switch that selects between the various rigs in the shack. Everything is fine as long as I remember to switch antenna ports before going QRO with 200 watt, since the WM-2 will probably fry if it gets hit with more than 20 watts. It sure would be cool if you could set power output maximums in the antenna memories, but I imagine I'm the only one who has come up with a need for such a thing.... 73, Brad AA5CH ------------------------ Yahoo!
