Elecraft CP1

Has anyone used the Elecraft CP1 for Puresignal ? DXengineering has these in stock whereas the Xtronics unit is backordered on HRO.

It's not clear what kind of coupling gain flatness it has over 1-30MHz, so watch out for any major gain variations.

Obviously it is only good to 250W when built as a 30dB coupler.

Assuming you are using a 100W radio, even built for a 30dB coupling factor you will still require an additional 10dB of attenuation on the coupled port for a total of -40dB relative to the input signal so that all inputs to the back of the ANAN remain below +13dBm.

With those caveats it ought to work.
