|

| which meant each signal needed its own pin. Some AIOCs were
| D-style connectors with up to 15-20 pins that were not compatible
| with things like VGA/DB25/SCSI types of computer cables. Going
| digital drastically reduced the number of pins for old parallel
| connections and down to one as the signal became serial. My
| favorite was SDI which carried the video and audio down a single
| pin coax cable with a twist lock BNC connector. Consumer grade
| released DV cables and then HDMI. Both of which are inferior in
| my opinion specifically for their lack of locking when connected,
| but their extra pins do allow for interesting things consumer
| friendly like ARC and ethernet/data stuff.

|
| Reminds me of the Technic 1200s. Built in the 70s, nearly

| 2.) Plenty on YouTube nowadays (Ham Radio Crash Course, W2AEW,

|
| On a personal note:
|
| Today actually marks my tenth year of being licensed :) 10
| Years ago I took the tech and general class exams and passed,
| after studying some of the Gordon West books and using an
| Android app question generator at the time. 9 Years ago (at
| time of posting this in two days), I upgraded to Extra Class.
|
| Like most new hams nowadays, I started out with a $35 Baofeng
| and $20 RTL-SDR dongle. It wasn't till after college and
| getting a full-time job that I finally invested into HF (Yaesu
| FT-991A, FT-818ND). For the past year, I've been building QRP
| rig kits, and learning CW.
|
| Having a license definitely gave me some bonus points on
| job/internship interviews for electrical engineering jobs
| (Specifically RF/Mixed signal specialized positions).
|
| Hamfests, especially the bigger ones like Orlando Hamcation and
| Dayton Hamvention, if you're very lucky like me can get some
| pretty good deals on test equipment and second hand rigs. I got
| very lucky last year in finding a Signal Hound BB60C Spectrum
| Analyzer for $400! (Current MSRP is pushing $3600+).
|
| I've heard and seen a lot of negative stories about the hobby.
| Yes a lot of older folks (the "RF-Boomers" as I like to call
| them) tend to be pretty stubborn and hostile, try to avoid
| them. There are a lot of good folks that want to help (the True
| elmers of the hobby), spend a lot of time with them. I've been
| very fortunate to be a part of two clubs (Dayton Amateur Radio
| Association, and Platinum Coast Radio Society (Melbourne, FL))
| that are very welcoming, friendly, and very active.
|
| I can keep writing about all of the positive aspects of the
| hobby, but TL;DR I highly recommend it!

| The emergency preparedness aspect of Ham is highly under

|
| First, most modern handy talkies (what Ham's call their hand
| held radios) are also very solid "scanners". In so far as you
| can tune in to a lot of different frequencies and listen.
| Weather alerts, AM/FM Radio (like the kind you used to listen
| to in your car before spotify)... you name it. Super handy if
| you say, lose power and cell service.
|
| Speaking of which, remember that cell service is heavily
| dependent on a number of external factors. Like the antenna's
| still being upright (earthquakes, tornado, hurricanes are
| bad). There still being power. There still being connectivity
| (typically fiber optic)... and most importantly - NOT being
| overloaded. With a Ham radio you can listen or transmit, with
| no other dependencies.
|
| For more local issues, like hiking or camping. Even if you're
| out of cell range, your radio may very well work. A 5W handy
| talky can reach up to 30 miles, depending on your location
| (basically line of sight). If you can get to the top of a
| hill or mountain and get a clear view - you can get a signal
| out to someone. All you need to do is get on the 2-Meter Band
| Calling Frequency (146.520 Mhz) or the 70-Centimeter Band
| Calling Frequency (446.000 Mhz) and it's a safe bet someone
| out there is probably listening. Even better if you've looked
| up local repeaters in the area.
|
| Also, the radio's are stupid cheap now. BaoFeng makes "cheap
| and cheerful" (nicest way to describe them) handheld units:
| Like a 8watt unit for $70 USD.
| https://www.amazon.com/BaoFeng-BF-F8HP-Two-
| Way-136-174Mhz-40... -- They even sell 2 packs of slightly
| weaker radios for $50 total. Are they the best? No. Should
| you splurge and get something better? Totally. Like a 10W
| radio that support DMR (Digital Mode) for $180
| https://www.amazon.com/Radioddity-GD-AT10G-Handheld-
| Digital-... . But if you just want to get your ham and use it
| once-every year... get a $50 radio and toss it in your car or
| something similar. Just make sure to get alkaline batteries
| for them. Lithium rechargeable are nice but lose charge over
| time.

|
| If you just want to chat and/or have emergency comms for

|

|
| I'm a hiker and a ham and I carry both my ham radio and an
| InReach. Only the latter I really consider my emergency
| comms. The radio is more for fun. Nobody monitors the ham
| frequencies professionally unlike InReach which is backed
| by the GEOS emergency center. A PLB is arguably even better
| but I don't go into situations where I'd really need it and

| For major emergencies it's a different thing, when there's

| That's not to say people were unfriendly- everyone really was

|
| The technical stuff is super fun and you could spend a lifetime

| BUT if you don't make a social connection and interact with

| (probably good enough reason alone to get into it), and because
| I see the appeal of it as a hobby, but I almost never use it.
|
| There is a ton of events and things people do "in the
| community". There are competitions of all sorts, and meetups,
| and radio-related things. I haven't done any, but I also didn't
| see much in other comments so I'm hoping people with more
| knowledge can share.
|
| There's also related tech like packet radio which is kinda like
| "dial up over radio". That's what the original article linked
| would most likely be used for. There are emergency prep groups,
| including completely digital tech that doesn't use traditional
| radios like SFWEM and AREDN (basically an emergency mesh WiFi
| network using special frequencies and commercial equipment).
|
| The test was easy to anyone with a technical background
| (electrical, not software). To everyone else it's still pretty
| doable with studying and prep. I was in school studying
| electronics, but I think I studied for like 3 total hours for
| the test. It's a mixture of topics ranging from regulation to
| antenna information. IMO the test gives you a good insight into
| part of the hobby. If you enjoy studying for it you'll enjoy
| the technical stuff.
|

| Much thanks for the pointer.
