What I did to make the BC1-T operational on CW would apply to many other broadcast transmitters. Don k4kyv Hey Don, This is a great story, and a labor of love. Thanks for sharing this with the group. One passing remark I wondered about while reading this essay is whether it was feasible to stick with the stock 10 Henry choke, and resonate it to 120 hz with a suitable oil type capacitor with a value somewhere around 0.15 uf @ 5 KV. (10H || with 0.15 uf = ~ 130 Hz resonance). I have limited experience with this approach, but the one time I tried it, it seemed that the critical inductance need dropped leaving everything else constant, and the AC ripple coming out of the filter was far less than a normal choke input filter. I did not do dynamic load variation tests however, so who knows.. Great Story Don! Jim JKO -- No virus found in this outgoing message. Checked by AVG Free Edition.
