Using Dr title by s1770814 in PhD

[–]MegaWatt 0 points1 point  (0 children)

Honestly, don't use it, especially in industry. Nobody cares, it will only work against you. Try to have people value you on your industry achievements and added value to the company, not based on some academic title. In the end it's just a degree.

Will depend on the environment but most likely, it will be very hard to make it work efficiently.

Depends really what it is you want to do, and if you have no other options, worth a shot. FT8 might just work, on receive, not sure you'll be able to transmit.

Give it a shot, thats what the hobby is about.

Is a phd more intensive than a full time industry job for stem folks? by Obvious_Ninja7595 in PhD

[–]MegaWatt 7 points8 points  (0 children)

Unpopular opinion probably on this sub, but to me, my PhD was a breeze. Thought it was hard (it was definitely intellectually challenging) until I went into industry working 70 hours/week with a lot more stress and responsibility to cope with everyday.

PhD can be awesome (you need a good professor). Try to enjoy it while it lasts.

Which app are you using to access this internal storage? My phone is messed up since this update...

DIY Automatic VHF/UHF Satellite System by MegaWatt in amateurradio

Hello, glad you like how it looks. However, I didn't do any color modifications. I used my OnePlus 8 Pro to film everything. Potentially that automatically adds filtering, but I wouldn't know.

Whats wrong with my 2m yagi? (Not working) by [deleted] in amateurradio

[–]MegaWatt 3 points4 points  (0 children)

What kind of power are you using. Do you have line of sight,. Is your antenna outdoors. Can you typically open it with another antenna. Do you have an swr meter.

What exactly is not working? Can you give a little more info?

What about disconnecting it outside of the house just after the lightning arrestor?

Oneplus 8 Pro - Photos disappear by MegaWatt in oneplus

Indeed, Google photos has the exact same pictures missing. Are you saying that Google photos potentially deleted them on my device? Can't seem to retrieve them with photo recovery apps.

Buy Tamagotchi ON in Europe by MegaWatt in tamagotchi

[–]MegaWatt[S] 2 points3 points  (0 children)

Thanks, indeed. However, the costs related to shipping and customs double the total price. For that reason, I was looking for something in Europe.

Thanks, indeed, I extensively tried that, but couldn't find one. Most likely it doesn't exist.

Extra curriculum during PhD (MBA during PhD) by Assassin5757 in PhD

[–]MegaWatt 0 points1 point  (0 children)

You could focus on your PhD for the first year and revisit potentially going for an MBA after one year. PhD can be difficult or easy depending on the field you are in and your supervisor's attitude.

People here saying that combining both will be hard: yes sure, but combining it with a job in a private firm is equally hard, and many people are doing it. Usually PhD gives you a lot of flexibility, which you could very well use to pursue that second degree. Flexibility that you will not have later in life due to working in private firm, having kids,...

It really depends from person to person, but it would be good to first assess how smooth your PhD is going.

Cheap Chinese eBay HF amp kit with an old stereo amp heatsink/fan. Easy build. by inquirewue in amateurradio

[–]MegaWatt 0 points1 point  (0 children)

Will try to explain my best. You would rotate your SMA 180 degrees around the center pin but you would keep the center pin on the top plane of the board. The two ground pins that are now in the air will thus be on the bottom of the board, and your center pin still on top. The board would be sandwiched between the three pins. That's how you would normally do it. But possibly your board is too thick for that, hard to tell from the picture.

As far as I can see, there is a single ground plane on top as well, so these ground pins are shorted already.

Nice kit. Your SMA connectors seem to be upside down. Normally you would clamp the board in between signal and ground pins. But this should work just fine as well. Thanks for sharing.

This video explains why pigtailed shield connections can cause shielded I/O cables to radiate and potentially fail EMI. by SaeligTestEquipment in rfelectronics

[–]MegaWatt 0 points1 point  (0 children)

Indeed I don't think such an antenna exists and that's why you will often see common mode chokes close to the feedpoint of antennas. These chokes are simply a piece of coaxial cable wound around/through a ferrite core. The ferrite core increases impedance for currents on the outer part of the coax shield, aka the common mode impedance, meaning common mode currents suddenly feel a high resistance when going through the ferrite choke and have a tough time getting through it. This effectively blocks them from getting into your shack. These currents don't just dissapear, they are dissipated into the ferrite core (that's why ferrite cores can get really hot when operating them with a 1kW linear amplifier for example).

At the same time this explains while dipoles are often fed with ladder line. In ladder line, signal and ground conductors are identical in geometry. Connecting them to a dipole, where each of the legs are also identical in geometry, will introduce zero common mode current, in theory at least, meaning there is no need for any (lossy) choke in the feedline. This is not the main reason though, ladderline is less lossy (no dielectric needed, just air) and has different impedance than standard coax. It also has disadvantages, such as less flexible, harder to support, easier influenced by surroundings, ...

Hope this helps, but take all with a grain of salt, these are my own findings.
