After thinking I needed to get an SWR meter for checking my 2M Larson antenna, I suddenly realized I'd be miles ahead and better off with the Antuino. I ornded one on Saturday and hope to get it soon. I anticipate it is much better than an SWR meter and does not need to transmit a signal to check the SWR and, also, I can see which way the antenna is off frequency and make adjustments without even taking the 2M rig to the car. I still wonder how it is used to measure power, as I understand it does, and what power limits it will need to keep in mind. The idea it will measure QRP power and do it within 10% (plenty good enough1) is where I'll use it mostly but also may want to measure up to 100W. I expect more detailed instructions will come with the Antuino...

I believe I'll find the Antuino a bargain when added to the home equipment. I also anticipate doing a better job of alignment, possibly, by listening to WWV on 10MHz while listening to it on my HF rig. When I "swish" to the same frequency, I can then zero-beat the WWV and Antuino frequencies and see how far off the WWV signal is. Ha

I can also verify the frequency counter by reading the zerobeated signal and check what the frequency counter readout says. Another bonus feature. The WWV transmitted signal is not easily read with a frequency counter without some means of producing a usable related signal for the counter.

I see using the Antuino in ways I never used before. One or two uses I can use right away but the possibilities are many.
