It's a collection of hobbies.
Being able to flick on the radio and see if you can send your voice into Germany or Argentina or Antarctica is kinda cool.
Or being able to communicate where there isn't cellphone service with something better than toy talkie talkies or CB is cool.
Or having a free GPS tracker.
Or making antennas and seeing how well they work
Or regularly shooting the shit with people in a 1,000 mile radius and making sure they're safe and happy.
Or chase awards. Talk to all 50 states, or 100 countries or ...
A lifetime of opportunities for a one time fee of $15.

modern communication technology is capricious trash that doesn't work half the time because of a mixture of certificate errors, incompetent installation, and government oversight

meanwhile if you have a radio, while there are still laws, the link is completely under your control. you're not going over any leased lines, you don't have to worry about intermediate stations sniffing your shit, you control the encryption from end to end, etc.

also there's some broadcasts that are worth picking up, most notably weather and satellite imagery

Surprisingly enough, I use 4chan and have friends (humblebrag, I know). one of these friends got me to join the Ham radio club at our university. Eventually we get to the point where he's running it, and I'm the vice president. This dude is so into ham radio that at this point, that he has several non functioning radios that he plans to fix up, and talks about it alot. He also wants to use Hams for club communication, which wouldn't be a problem at all. except for the fact that he doesn't have a functioning radio to talk on the local repeater, and HE DOESNT HAVE A CELL PHONE PLAN. This fucker has left me hanging for more than a week at one point because he forgot to check discord. the idiot is like 21, in college, has an android, but refuses to pay for a phone plan, saying he'll just use the radio.

IIRC, it may have to do with turning your whole house's electrical system into an antenna.
I had scrap wire and an iron incoming water pipe, so it was an easy solution.

[Anonymous No.1896551]

>>1896547
Thanks, so any tips how to improvise RF ground?
Forgot to mention I will have attic antennas only, with the roof lightning-protected.

[Anonymous No.1896552]

>>1896551
There are a lot smarter than me here.
I'd get a lightening arrestor and tie that into the roof's grounding rod (if you think it's needed).
Then for the RF in the shack, I took a copper water pipe, hammered it flat, and tied each piece of equipment in the shack to that(a busbar would work as well, pic related) then ran a wire to the incoming water pipe. Others use a grounding rod. You can make/buy an artificial ground if absolutely necessarily.

[Anonymous No.1896554]

>>1896550
There is a lot of theories and competing theories and misinformation.
Thankfully, RF static is usually very low voltage and appears as QRN or a 'bite' or minor shock. I think I eventually just tied it to the incoming water because the house electrical is also tied to the same water pipe, which kinda goes back to your original observation of the electrical neutral. I'm happy I used 6awg instead of the house's 14agw, and it's 1/4 of the distance.

not strictly /ham/ but still radio related
it's a known phenomenon that cell phones will nuke their battery in areas with poor/no reception, trying to "find" a stronger signal

my question is, with antennas being passive devices, how exactly are they expending that energy? Are they just turning an amplifier up to 11 to try and find whatever signal there is?

Yes, the power amplifier is maxed out trying to reach a base station. On contact there is a negotiation where the mobile phone reduces power as much as possible. There are tons of patent applications relating to handover and power management.

Although there is currently no fee for vanity call signs in the Amateur Radio Service, we find that such applications impose similar costs in aggregate on Commission resources as new applications and therefore propose a $50 fee.

In some instances, the Commission does not require certain equipment to undergo authorization procedures. For example, part 97 rules do not require amateur radio equipment to be certified. [However] According to 47 CFR § 97.315 the rules do require external power amplifiers designed for use at an amateur radio station to be certified.

They work, however they need constant re-tuning if you change frequencies a lot. They are expensive compared to other antennas. Yes, you can build it yourself, but the most expensive part is the cap. The other thing, if building yourself, is they require tight tolerances otherwise you end up loosing bandwidth and signal. I'd go with an alexloop or w4op loop before the chameleon.

HAM is a based and retarded hobby. There is such a lag between the technology available and the technology used. For example, the 300 baud rate limit on HF when digital modes like Pactor 4 and FT8 exists. This is like if fibre optics existed but the government only let you use dial up. SDR technology and modern electronics not being widely used and outdated standards for equipment design (boomoids still using vacuum tubes), retarded and redundant FCC regulations, the list goes on and on.

But since most white jews (boomers) are getting PILLOWED I think this hobby is hopefully going to have a renaissance, because there just won't be anyone to enforce the arbitrary rules the FCC puts out there.

I want to be able to close the pouch pictured with the radio inside and a long antenna and PTT outside. If I run the coax cable down out of the pouch instead of running an antenna straight out of the pouch the top flap of the vinyl pouch will close properly and offer some rain resistance to my non-waterproof UV-5R (I picked the UV-5R to start out because it seems to have a larger hobby community and aftermarket than other affordable handhelds). When it's not raining, I'd like to be able to adjust radio settings while moving.

neat. i built a 80/40/20 but a lot of the pvc is sliding. used some zip ties to try to keep them from moving around...i would like to get it in shape before the winter.

shit, id also like to get my tower up. built a 6m yagi that i would like to play around with. would like to put a few slopers off that. big plans, just not enough time

The "grey line" is a band around the Earth that separates daylight from darkness. Propagation along the grey line is very efficient. One major reason for this is that the D layer, which absorbs HF signals, disappears rapidly on the sunset side of the grey line, and it has not yet built upon the sunrise side. Ham radio operators and shortwave listeners can optimize long distance communications to various areas of the world by monitoring this band as it moves around the globe.

>free WiFi in 500m
If the bidirectional biquad works 'just so', the unidirectional will work well. Always check the polarization. Most access points or routers are vertically polarized. At 2.4 GHz you want a short, low-loss cable. Since your 'free WiFi' is in a fixed direction you could also try a narrow beam 'cantenna' which is cheap and easy to build.

I've had good results this summer with an offset Windom. The only downfall was the inability to get on 60M or 160M.
I'm thinking of making one for 160M with winter fast approaching. Has anyone experimented with winding / snaking a dipole? I was thinking of using something like a 1"x1" piece of wood as a spacer, then an eyelet to raise each end as well as the middle.

I learned about the dB and the question was:
How much is 8W compared to 5W in terms of S units?
If 1W=0dB then 8W=9dB and 5W=7dB. The difference is +2dB or (1/3) of one S unit which is 6dB, twice the voltage, 4 times the power, twice the range.

[Anonymous No.1916040]

>>1915545
>(1/3) of one S unit
You cannot divide dBs, only add or subtract. 8/5 = 16/10 = 1.6 = 2dB is correct and 1 S unit is a power factor of 4. But 16/10/4 = 4/10 = 2/5 S units, not 1/3. Orisit?
