During the last couple of flights I've started to get generator noise on the radio. Snap crackle and pop, not a regular frequency noise. Came to the conclusion it was the generator by turning it off, then the noise stoppped.
Old ('60s), PFA, wood and fabric aeroplane, O-200 with a Delco Remy generator into old fashioned (ie not electronic) voltage regulator. ICOM handheld with SPA 400 i/c. Had no problem with this set up before.
Could it be a faulty voltage regulator? If so could it be easily replaced by a new, electronic one, or do they only work with alternators? I did try cleaning the contact breakers on the voltage regulator to see if (like on a set of points) there were poor contacts causing the problem, ground run afterwards didn't show any improvement.
Any thoughts please?
