I cut a scrap of PC board to the size of a filter and used three toroids with tuning and coupling caps. It worked just fine in position one, set up as 13 KHz. The DSP hasn't suffered at all. Maybe with more antenna gain one might see some overload from nearby signals, but not with my modest wire. I sure wouldn't transmit with it, though. It's hugely wide, offering no attenuation of unwanted mixer products.
