[hpsdr] Pennywhistle with feedback

[Chris Day]

I'm about to build my Pennywhistle, but the stock values will probably give me too much power for my HFProjects SuperPacker Pro 100W amplifier, which only wants 5W. Has anyone experimented with the optional feedback on the Pennywhistle? What should be used for the secondary winding? I figure it would be wise to put that in place when the transformer is constructed. I'll try to dig up the method for calculating the R2/R12 resister values, but any hints would be appreciated. Thanks.
