This Saturday there will be a group of reenactors giving demonstrations and tours and the like along with a military vehicle show. The event mainly features a WW2 theme but in the last couple years they have also included new displays from Korea and Vietnam on the periphery of the event. The last two years I have brought out my M151A1 and operated just outside the main gate to Fort Miles. I have regularly done the MRCA net on 5.357 at noon local time and this year I will also try the MMRCG net on 7.296 at ten in the morning. Will also monitor 51.0 FM.

I have a TCS-12 and the AM power is also down-limited from CW power. Does anyone know why it was designed this way? And is it possible to bring AM power up to CW power ratings on a TCS-12? Thanks for any info.
