How much power is really needed for AM? Is 200W enough? I have been trying to get a vintage AM station on the air for the last couple winters. Last winter, I worked on a Johnson Viking 2 for a while until I figured out the mod transformer was bad, and I could never find any proper crystals. So I got sick of it and sold it at Dayton. Then in the summer, I picked up a couple Valiants, and a couple Rangers. I have worked on the Valiants this winter, only to find that one has a missing LV transformer and the other has a bad HV transformer. I guess I need to transplant transformers from one to the other or find a couple transformers. Then in the last week, I have been working on recapping a Ranger and the Courier Amp, which I am almost done with. So last night I was listening to a group on 75meters and tried to jump in with my Icom 7300, but I don’t think anyone could hear me, looked like it was about 30w. Was my first time trying AM. Maybe this weekend, I will have the Ranger done, and with the Courier Amp, I should be around 200w AM, so hopefully that all goes well.
