[Elecraft] WM-2 / 100 mod ?

[Don Brown]

Hi

The peaking adjustments are made at around 5 watts. If you readjust the power out control a little after each adjustment the K2 will re-read the power out and you will not peg the meter on the WM-2 as you bring up the power to a peak. Once I have each band peaked at 5 watts I check the output up to 10 watts on the WM-2. The WM-2 has 10, 1 and 100 mW ranges. I have been very happy with my WM-2. It is easy to use and accurate. The only complaint I have is, it does not have a way to check the battery or a power on indicator. Although this should be easy to add.

I posted a write-up some time ago on how to modify the OHR 100 watt dummy load into a 100 watt 20 db attenuator. When connected to the WM-2 the 0-1 watt scale is multiplied by 100. The mod works quite well but it does roll off a little at 10 meters due to stray capacitance. If anyone is interested I will re-post the instructions.

  Hello again,
  I read with interest the comments on the Oak Hills WM-2. Which brings up a
  probably stupid question: the WM-2 has a limit of, I think, 10 watts. <snip>

  And that IS a limitation, indeed. What would it take to add a 100 watt range 
  to the WM-2?
