when it says variable output between 5w, 2.5w, 1w, does it mean that there are 3 different radios or is just one that you can regulate the power?

Single radio multiple output settings

I can verify they do not float!

Can this be tuned to channel 123.025?

The HX400IS is Marine VHF radio. I believe the 123.025 frequency is a UHF frequency and needs a UHF RADIO to tune it.
