About
The DWM V2 is the second version of the SteamingCoax series digital wattmeters for digitizing the legendary and time-tested line section systems made by Bird Technologies and Coaxial Dynamics.
​​
The DWM is only the readout in the line section system, a line section and element is still needed to complete the measurement system.​
​
This meter has been entirely designed inside-and-out and funded by me (Robert) since its conception in 2022, who has been passionate about the RF space since 2017.
The Journey
It all began after working as a RF Technician for Radio-Canada and becoming more and more frustrated at trying to estimate power levels off walls of 30+ meters almost every week and the only solution was to purchase a $5k digital read-out, only for the display to tiny and hard to read.
​
Once I decided to go back to school and pursue my electrical engineering degree, that's when I made my first prototype:​
After a year of development, the first version of the DWM was ready for sale! Only 25 in existence.
Another year and a half later of development... We have the DWM V2! More than 250 are out there currently!
