Palomar Maxi Mod

This is a sensitive subject, why can’t you be supportive here? Imagine the people that believed this lie, that fell for this crap. We’ll all need a shoulder once this gets spread and all you can do is poke fun.

How rude!!!
 
Can you explain that, been thinking bout it. Why does muh thermocouple reading not jive?
The thermocouple can not be just the two wires hanging out in the breeze. It need to be contained and protected from the environment. The two wire are welded and if the welded wire touch bare metal it can pick up electrical interference from that surface,
 
I expected to hear that it was flawed because of how it measured, you know, without a heatsink. But hey, temps is temps, right? Again..muh thermocouple.

Or I really expected to get pummeled because previously I used one with a smaller chassis, is that thermal mass?, and then a larger one which I’d expect to see a lower temp or heat up slower. Didn’t somebody say that already in this thread?

But I’m stickin’ to muh thermocouple because it’s my Death Star and I own it, it and the thermocouple. I gained 1.21 jiggawatts by switching to transistors I measured off heat sinks and with my probe.
 
Time to get serious! The most common thermocouple I have used is the type "J."
ironconstantan which is good for -50 C and up to +770 C. With a low level output requires amplification to read and convert to a corresponding temperature.
Now take that thermocouple and touch it to an energized circuit and all of your readings become false. We made our own TC's in engineering since we used so many in any project. Each and everyone of those thermocouples was dipped in a Dental Cement and tested for surface conductivity.They would take all of my calculations for junction temperatures and compare them to the real live readings and then they would calculate back to see what was happening. My Calculations were for predictive protection and the live readings verified how it was actually behaving and adjust accordingly.
This was a full blown "Mil-Specification" engineering house used by the DoD to check other manufacturers actual performance as well as our own products.
We would laugh at some of the primitive crap we saw.

So you’re saying I can’t just hang my dang wang or mosfet out in free air, take some Scotch tape and wrap it around a probe sandwiched to said wang or mosfet and get a scientific reading??

Are you trying to tell me that have to use a heatsink?

Again man, muh experiments. I was in a closed room with the AC set at 72, the humidity was 46% and the room was a cool 72.7 degrees. MUH EXPERIMENT!!!

You saying that ain’t worth jack?
 
Well I’m not an engineer but I play one on TV.

If I were gonna do this, I’d mill a section of the heatsink, mount the probe in it and use some sort of thermal adhesive. Then I’d put a probe on the back of the heatsink and one on the front of the device. Throw one in for ambient temp for good measure. Play some music while I was testing it, like the kind they play in shows and movies when are serious and they’re wanting to stress that point.

Then wait until next week to reveal the results. That’s how we do it on TV...

Muh rating!!

"I'm not sure how his name came up but I just asked a simple question since if one generates more heat or draws more current to achieve the same result then it must be an inferior component." -Rabbiporkchop

sigh. the shell game continues.
Here, Rabbi expects us to believe that his question has nothing to do with the video that FTCB put up just yesterday:



"Whichever component requires the least amount of heat sink would probably be the best component to choose at least that's what common sense would dictate." -Rabbiporkchop

well it's a good thing that manufacturers of electronic devices require their engineers to have actual degrees instead of just 'common sense' since many times things seem counter intuitive when you don't know what you are looking for.

for example, putting a heat probe on the back of a transistor in order to test how efficient it is. common sense might tell you that the transistor that gets the heat to the back of the transistor faster would be the more efficient transistor.
which transistor would that be in the video?

see what i mean about 'common sense'?

Rabbi, i'm not making this stuff up, go read the page i linked to earlier. it's all right there.
as i said before, i'm willing to give Mark the benefit of the doubt that he's just ignorant, and not being intentionally deceiving.

EDIT: i guess i didn't put the link in my earlier post.

Thats all that Hard Drive does is Bash other Shops,if he is so great he sure does have alot of time on his hands to make lame videos and he never shows anything what he does to Radios.

Well, you know the saying that is used “those that know it show it, those that don’t won’t”.

At least the correct grammar is used for won’t, you often see “want” used way to many times to blame on autocorrect.

And let’s not forget “if they don’t show you or do so in a deceiving way, you’ve been mislead”.

No truer words could be spoken by the radio savior, giving a prime example with real world samples to go by in every video thrown on YouTube to draw attention to ones self.

The MaxMod is nothing special, just like the 2030’s, it’s all a preference as to what you want or like. But that’s not good enough, so sayeth our savior 163, for thee will bow down before the Palomar MaxMod and give thanks unto the 2030’s for saving our radios from the evil known as 13n10, Amen. For he who knoweth true evil and who has witnessed its fiery fury will not be forsaken in the house of HD.
