I just got a an annual fluid film undercoat, and I’m a fan because if the effectiveness against rust where road salt is used a lot. However, there are two things one might not be entirely prepared for after the treatment.

1. The undercoating is a very effective lubricant for the brakes. I was surprised by how hard it was to stop initially, but driving around and using the brakes burned it off relatively soon.

2. I also noticed that the body exterior was misted with the agent. A car wash will likely take care of that, but be prepared to clean the windows - the windshield was very greasy, and needed window cleaner (not just the windshield washer) to remove it.

These are minor issues, but something to be aware of when you get fluid film.

In the Kohler generator app, the “True Total Power” and “True % Rated Power” of a generator are expressed as a negative number. Why is the apparent convention negative?

Why are intervals based on a unison of “one” not “zero”? E.g. why is the Dominant a “fifth”, when it is only 4 scale degrees higher than the tonic?

Starting with a unison, the interval of a unison is designated a “first” not a “zero”, despite both notes are by definition identical. Why is that?

Could the answer be that when building a chord, the lowest note is by convention “one” not zero, essentially pushing the “scale-degree count” up by one? If so, then a triad therefore becomes a “third” even though it takes only two scale degrees to arrive at the “third” note.

I find this nomenclature confusing, as it is non-mathematical. Your thoughts?

I am currently using a Denon HEOS system with an AVR and only multiple network speakers (no wired speakers on the AVR). My network is a recently updated NetGear Orbi with three mesh nodes and a main router. TV sound grouping on the AVR is off.

The audio is not in sync, playing with a subtle but objectionable delay from room to room. Sometimes the delay is more pronounced than other times. I have an open floor plan, so hearing more than one speaker at a time is common. Sometimes stopping and starting the music stream helps when it gets more dramatically out of sync.

Does anyone have any ideas about how to resolve this? I fear that it is intrinsic latency in a mesh network, but if there’s a fix I’d like to know it.

I have what is now a very robust mesh system for my Denon components (NetGear Orbi 871/870 with three satellites). A new AVR and four speakers are all on static IPs at 5Ghz IoT; same channel; signal strengths -50 or better, all “excellent” connections according to the HEOS network diagnostics.

Despite what appears to be as much as I can do to optimize the network, I still have instability and audio dropouts when using the AVR for the tuner or CDs. Streaming audio such as Pandora via the network player is flawless. I occasionally “lose” the AVR and need to restart it.

Reboots of components and the network itself seem to help when dropouts are particularly severe, but performance devolves after an hour or so.

Any ideas about how to get more system stability?
