Good morning!!!!

[m7040]

good morning, 52 going to 62 warmer and raining a little with more to come today

we got the vac shoots and I dont feel anything but wife has a sore arm

Moved some of the firewood and improving the technic to fill the bucket on the loader in one scoop without having to get down and manually do it to get it topped off.

Cody loves the cooler weather since he always has his double coat on

54 and drizzle heading to 64 and sunny this afternoon.

Scotty, that looks like quite the setup. Can you talk to someone in the DR before you go there for vacation?

Yesterday was Yoga day at our house, so I took Della to the mountains to work on my SNP 500 goal. Hiked from Skyland down to some waterfalls on a horse trail and back up a different trail. It was 36F and drizzle/fog/breezy all day...not a day I would have picked, but it was quite nice to be out there.

You can see very little flow since it's been so dry...there is a footbridge visible through the fog.

When we got back to near the parking area, we walked by the stables...I wondered out loud whether any horses were still there, and was answered by a loud neigh. They take the horse down to the valley in the winter

Scott, that's a nice looking setup, as one who used to
own a "radio shack". I'm sure the AC is protected by a surge protector,
but what do you protect the antenna lines with?
lot of very sensitive equipment
are there whole system filters on the input side?

I can only wonder if MOVs affect the bandwidth in some way
and thank you google AI but apparently this can be an issue affecting reception

Yes, metal oxide varistors (MOVs) can
affect radio bandwidth, particularly in high-frequency or radio frequency (RF) circuits, due to their inherent capacitance.




Here is how:

• Inherent Capacitance: An MOV acts as a dielectric medium between two electrodes, giving it an inherent capacitance (typically in the picofarad range).
• Frequency-Dependent Reactance: In AC and RF circuits, this capacitance creates a frequency-dependent capacitive reactance (
  
  
  
  Xc=1/(2πfC)cap X c equals 1 / open paren 2 pi f cap C close paren
  ).
• Filtering Effect: Since MOVs are typically connected in parallel to the circuit they are protecting, this capacitance can shunt high-frequency signals to ground, effectively acting as a low-pass filter.
• Signal Degradation: As the frequency of the signal increases (e.g., in the RF range), the MOV's reactance decreases, allowing more of the signal to be diverted. This can lead to signal attenuation, distortion, and, consequently, a reduction in the available bandwidth of a communications line.
• Design Consideration: When used on communication lines or in RF applications, the stray capacitance of the MOV is an important parameter to consider during circuit design to ensure it provides surge protection without unintended circuit interference or signal integrity issues.

For standard low-frequency (e.g., 50/60 Hz AC mains) or DC circuits, the effect of the MOV's capacitance is usually minimal and does not significantly impact circuit performance.

nice looking firewood Frits. Plus your equipment always looks good.

after having my hvac system fried by a power surge/lightning/something,
which also belatedly I believe took out my dishwasher, for the first time, I made sure the
dishwasher was a plug in and plugged that into a heavy duty Tripplite surge protector.

our appliances are getting more delicate. They are now online with us.
more circuitry to get zapped and you can bet they don't spend the one dollar or less to build
in a nice MOV into their own product. In a user friendly/accessible spot with a plug in replacement.
no such thing, most of what we buy runs pretty bare.
MOVs are your friend

one Christmas I built Heathkit surge protector strips for my family.
now they are really cheap and should be used everywhere if you don't have a whole house unit.
and even then, on gear like Scott's, I'd have several layers of protection.

I am not sure higher surge ratings are the ultimate test of quality.
other than filtration, what else makes a better surge protector?

.42 rain and a dark rainy morning

Good morning, the low is 35 and going up to 48°F. Wind E 8 mph.

I don't think I've got anything on the go for today. I'll conserve energy. Will check lottery tickets after I post this. I'm not holding my breath.

As far as furnace oil suppliers go, we have a choice, the one I just walked away from or the one I just went to.
The one I walked away from bought the cheapest crappiest oil he could and then doped it up with additives to bring the cetane rating up to almost within spec.
The one I went to is Petro-Canada. Better oil, more bang for my buck and cheaper than the first one. Win, win for me.
The only propane I have on the property is for the BBQ
and that is two 20 lb bottles.

Time for breakfast.

Have a safe day all

If putting MOV's on an antenna, you'd want to find/buy ones specifically designed for the operating frequencies. I design stuff like this for commercial and military applications, but I'm not sure what's out there for consumer applications.

Good morning TBN!!
43 this morning and the rain has stopped for a few days at least and supposed to be breezy this afternoon.
We have gotten 4" of rain in 2 of the last four days. Good soaking rain that we really needed!


Good day yesterday. Finally going to call the electrics done on the buggy!! It starts on first crank. Purrs like a loud kitten, and shuts off with kill switch. Only thing I will do now is wire relay in so it shuts off with key switch ( due today) and whatever lights/acc. I want. I do need to do a little cleanup on the wire looms to make neat and tidy. Then I will turn to welding a couple of pretty rusted cross braces and the Artic Cat.
Not today though. Seems I have been forbidden from the garage today as it is our 38th Anniversary. I think we are going shopping for the garage instead. LOL
We may go look at some seats for the buggy amongst a full day of running here and there together. Just blowin' in the wind. Nice dinner later.

Time for a second cup
Everyone have a great and safe day!!

Near 30 degrees here in Houghton MI this am and we are packing to head to camp. Will post from camp if possible with just 1 bar there. Hope everyone's last of the week goes well.
