Yes, the Mk.1 Chore Horse had no interference suppression on the generator output - I suspect it was only intended for 'stand alone' battery charging and not float charging of the radio batteries.
So the 4 capacitors (two across the brushes and two in the control box) and the choke in the control box (which, to quote Henry Reed: "in your case you have not got") were a later British modification to reduce interference (which apart from being an irritation to the radio operator would also be detectable by the enemy and give your position away).
The Mk.1 is something of a Brute Force device.
Best regards,
Chris.
