We used to put "white" in mineral water bottles, and "brown" in iced-tea bottles. No need for food coloring! 😁I'd smuggle in Vodka by putting it in a Scope bottle and adding a few drops of food coloring.
Sorry, I am still trying to learn to use my new laptop (the old one died). My head is filled with radio questions and I am anxious to get down to the hangar to resolve the radio challenges.
Hi Vance. If you blew the GPS fuse and the transformer stopped working but the GPS continued on internal batteries without interference, it could be the transformer is creating some of the interferenceAfter a couple days of bed rest with what I think is the flu I headed down to the hangar to finish what I had started with the Lone Star Eliminator filter.
I figured a way to mount the filter and wired her up. I worked on the grounds and after a careful pre-flight inspection went flying for about 40 minutes doing eight patterns.
I would have flown for longer but a C130 was doing pattern work and I have a low fear threshold when it comes to wake turbulence from a heavy.
I called the tower on the phone afterward and Madison said the radio was loud and clear. She even went so far as to use the word “perfect”.
Unfortunately I am still hearing some loud intermittent static in the head set and it seems related to the power setting. I don’t get the noise at wide open throttle and I don’t get the noise when I pull the engine to idle. The most likely time for it to happen is when I pull the throttle back a little to maintain altitude. It stops making the noise as soon as I push to talk and the tower didn’t hear the static.
The panel is rubber mounted and I tried pushing on it when it was making the noise and it made no. measurable difference.
I feel it would be a distraction for a client so I am going to continue to work on her tomorrow.
I will dig around in the rotor tower making certain the grounds are clean with no resistance.
I think the noise from the panel power for the GPS is a bad male plug. It made the noise when I started her up, then I wiggled the plug and blew the fuse the noise stoped even when the GPS is on battery power.
Today was very satisfying even though I spent too much time upside down.
My video failed and that is where I heard the alternator noise so that is still an unknown.
I am excited with the progress.
I good suggestion; thank you J4flyer.Have you checked your headset plug ?
That is my thought as well JETLAGO3; thank you! The plug has gotten a little loose over time and I will replace them both. As far as the transformer goes that will require some parts. The first time it did it I removed the fuse to stop the noise, the second time I just wiggled the plug pulling it out and putting it back in and that blew the fuse.Hi Vance.

An interesting suggestion dunc. I don't have an oscilloscope and don't know where I would get one. My sense was the filter was doing a good job of filtering. This is pure conjecture on my part.You might try attaching an oscilloscope to the power bus to see how clean the DC power is at various throttle settings. A storage scope model would be best. It would trigger from noise pulses.
