effective but low efficiency Time Owned: 0 to 3 months.
I found many plans for building a resonant CW speaker on the web but took the easy route when I found this kit. Assembly is very simple, just some nuts and bolts. When plugged into the external speaker from my Yaesu FT-DX10 there wasn't enough audio for it. I had to have my Yaesu's AF gain all the way up and that was far too distorted. I added an inline LM386 amp module off Ebay and adjusted the gain of that amp to get approximately the same level out of the two external speakers I use.
The passive filtering of this resonant speaker is wonderful for CW. So much better than the typical active filtering. Its cleaner audio and nicer on the ears. It's 500 Hz center frequency might take some getting used to.
