[BC] Henry Radio 3 KW - blame for SCA crosstalk?

[wpio fm radio]

We're testing the 92khz subcarrier, and have two disturbing 
symptoms:

1. There is main to sub crosstalk (even with stereo gen off)
2. It sounds like all the treble highs are being rolled off.

(I know it's 4 KHz tops anyway)

The Henry Transmitters are a one of a kind tank circuit.

Could the Henry be the blame for 1 or 2 above?
