- I don't find a very good idea to place a power broad band transformer, with a saturable core, where the impedance is high. 73, Mauri I4JMY arrangement -- FAQ on WWW: http://www.contesting.com/ampsfaq

- I know about it, but there iron powered toroidal cores are used as inductors and not as transformers. 73, Mauri I4JMY -- FAQ on WWW: http://www.contesting.com/ampsfaq.html Submissions: amps@contestin

- You need exactly the same loading capacitor that you would need for a Pi-L network. The savings is that you need no L coil and no padding capacitors. The trade-off is that your harmonic suppression

- There are plenty of examples of 4:1 toroidal transformers used at the multi-KW range, usually to step back up to 200 ohms (or even higher). Proper core design and choice is necessary, of course, but

- You may well have problems meeting FCC harmonic requirements with just a pi. You certainly will not meet European requirements, or the ITU Recommendation SM.329-7 on spurious emissions with just a pi
