Hi Graham, yes ok, I have a Halcyon and that unlocks sometimes after dark. It may be due to noise and the use of the internal ferrite rod. There are quite big phase shifts after dark sometimes, and t

Hi Johan, yes a quick look suggests a value of anything over about 120uH would do the job at 136 with a 10ohm load. I looked for data when I started to experiment as I am sure you did and just built
