MTR v2 Completed
Finished the build of MTR but was not convinced the device is working optimally. I aligned manually by the manual without access to a real cro or frequency counter.
David VK3IL has these tools and has updated the firmware to addresses a minor bug with stepping through the band and expanded the bands to match Australian conditions.
Jumped at a opportunity to use the correct equipment to align the MTR and update the firmware.
David V3IL with the super specs and Glen VK3YY supervising.
After a short period involving probing measuring and adjusting the conclusion was 4W out at for 12V 8W in so 50% efficient. Both David and Glens devices were able to get 5W out. This must come down to the winding of the toroids. Combined with the addition of the capacitor to increase the audio gain the MTR burst into activity.
Very happy with the outcome. Finally got out 24th August 2014.See below for MTR in action in the Aussie bush,
