This topic has been around before, but I have not seen anyone bring it up in a very long while. Years back there were a few guys experimenting around with the old shunt-fed method in their Johnson and other transmitters. Basically, it’s the old method of removing the DC load from the secondary of your push-pull modulation transformer when modulating a class C RF amp. This is also often referred to as the Modified Heising method, but incorrectly I think. The old shunt-fed method is below... I was looking my McMartin BC transmitter out in the garage and it has the big 50H reactor choke. That transmitter uses the choke in a similar method shown below which I think is probably a much better configuration than the first one above and I think is a bit closer to what really could be considered Modified Heising, but using the push-pull audio amp. Anyway, both configurations are almost identical and I was thinking of trying the 50H reactor choke in my HB transmitter just to see what would happen and if the fidelity would improve even more. The fidelity was always fantastic with that transmitter anyway, but it might be fun to just throw it in there temporally and see. I think there is a spot where I could hang it with some strong cord or rope. Any thoughts or suggestions? .
