[Amps] Elecraft W2, nope

[Gary Smith]

Another good one is the WaveNode WN-2. www.wavenode.com

I have one in the shack, it shows fwd and reverse pwr, Is very accurate. also the software to have a display on the pc is nice to wow visitors (and yourself) from time to time.

  Elecraft W2 that I have is a nice toy to give flashing lights to the shack, but very frustrating to use to try to peak up a linear amp. The gradients of the bars in the bar graph are just not fine enuf to do the final adjustimet to an amp.  Skip this one.   I use the WM-1 from autek and it is also satisfyingly old fashioned looking, has both peak and incident readings.  73
