Jim, I am not sure about "the hang of this forum" thing. It is just public email where we try to help each other with Elecraft products.
You may have a problem with that wattmeter rather than the K2. Analog metered wattmeters are notoriously inaccurate, especially at low power readings. What range are you using on the wattmeter? The thing about these analog wattmeters (including the much revered Bird) is that they have their accuracy specified as a percentage of the full scale reading. That means if you are using a 100 watt scale and the specified accuracy is 10%, the reading can be off by as much as 10 watts - and that is true *anywhere* on the scale. Also, wattmeters can be frequency dependent. A normal K2 has more gain at 40 and 30 meters than on the other bands. Given the way the K2 controls power, you should have less current drawn for any given power output on those bands. If that is not true, then the most likely place to look for the problem is in the Low Pass Filter for the bands drawing excessive current, or the winding of T4. Also be sure Z1 and Z2 are in place and properly soldered. You might want to check the actual construction against the manual sections that detail the winding of T4 and its installation. If you do not have the manual, you may download it from www.elecraft.com. 73, Don W3FPR On 10/25/2010 11:25 PM, Shamrock wrote: > Sorry, Don, I don't have the hang of this forum yet.
