I bet that powerEsim software this is also incapable to define MossFet resistance characteristics.
Therefore with out Oscilloscope and with out current measurement probe, you will never solve the puzzle.
Lets start with the very basics, open dipole antenna this has 75 Ohm resistance at any frequency at transmitting or receiving.
The perfect loss-less line this should include 75 Ohm cable among with 75 Ohm connectors, in other words an entire 75 Ohm system.
Now proper measurement of 75 Ohm...
I use "silver content wire" or solder when I am making high quality metrology / calibration gear for my Blog.
A good example this is making bridges for a seven stages resistor decade box.

The dark side of silver this is corrosion...
How about you leaving the forum and not waste bandwidth?
Basically you are begging for help, you are not paying others for their trouble at engaging.
uc3842/3843 they are not compatible chips, I do such PSU repairs all day long (electric bicycle chargers).
But I will leave you in the dark...
Well this is good to know, select-able power this is a major advantage for the topic starter, which will do PCB and PTP (point to point) soldering over wires and connectors.
I am not impressed, this is old times investment this requiring pre-heater so soften the solder.
Either way my example was relative to PC motherboards and I am talking of soldering technology in use from 2014 and later.
Any one working with multi-layer PCB he is forced to get an 90W adjustable soldering iron.
When time and productivity translates to money, then 8~10 seconds heating time this is required.
I was able to get such a tool at the price point of 150 Euro, when Weller and others Famous thieves they...
This model is capable to demonstrate on screen only 2.000 points Wfm/s , this is like viewing entire information of 2 kHz waveform, at 4 kHz signal you will have 50% loss or reviewed information.
I do SMPS repairs, my scope can do 80.000 Wfm/s , I can not use anything with less than 60.000...
Generally speaking all compliance specifications they are goods that you have to buy from IEC or other organizations.
At my humble example with the loudspeaker cross-over at dancing room, also after misuse you will find capacitors and coils at the bottom of the case.
I was putting them back in...
So, you are from India.
The scope price this is at 199E or dollars, this is better than PC based Oscilloscope, but not sufficient than any other application than sound analysis.
In the positive side of things, you will earn your own experiences and if you do advance in electronics, your next...
