主題: Re: [Elecraft] lowest stable power of K2

Johnny,

To prevent damage to the K144XV from inadvertent overpowering at the input, I 
recommend you set the K144XV for 5 watts input.  That will allow you to run the 
K2 in a power stable range while driving the transverter.

If you insist on using a lower input to the K144XV, I recommend you look at an 
old mod by WJ4P.  That mod reduces the range for the power control to 1/10 the 
normal range  See http://www.madisoncounty.net/~kj5tf/K2mWmod.htm.  If the 
power range is reduced tenfold, the power stability should increase tenfold in 
the process.

There are also application notes on the Elecraft website that deal with 
milliwatting the K2.
