I'm going to throw in some stuff to the good advice above:
Hi, I'm new to the forum, and am looking into HAM radio.
Welcome!
I've had a landline telephone (copper wire) for decades. We no longer answer incoming calls, not ever, because of the volume of spam. We use our cell phones instead. The reason we've kept the landline was the idea that in a catastrophic event (like earthquake, I'm in California) with power and cell towers unavailable, we'd have a shot at using the landline for communication. For various reasons, maintaining the landline may not be possible, so I've looked into other methods available to communicate if one doesn't have access to cell or Internet. It seems that a satellite phone and HAM radio are the options. So finally, if you're still with me, here's my questions and the reason for posting this message.
1. Is it realistic to think that with a Tech license I could have a functional communication channel in an emergency?
No. I'd disagree with the others on this. Ham radio is not a functional communications solution, ESPECIALLY in an emergency.
Remember, ham radio operators are just regular people. There is -zero- requirement that they be listening or even respond to the radio. There is no huge team of people there listing to the radio 24x7x365 waiting for you to call for help. It's random guys using radios as a hobby.
Reaching another human being depends entirely on where you are. There may not be another ham operator within radio range. Even if there is, they may not have their radio turned on, be on the right frequency, or even listening.
Yes, there are repeaters that cover some areas, but again, no requirement that anyone be listening or even respond.
Reliable radios that you could depend on in an emergency are not cheap. Don't buy a $20 Chinese radio off Amazon and assume that'll put you in contact with anyone.
The radio is ONLY useful if there is someone at the far end. Unless you have everything pre-arranged, that alone puts everything in question.
Ham radio is NOT an emergency radio service. It's a hobby. The people on the radio are not first responders. They are not 911 dispatchers. They are random people that have zero requirements to assist you.
Ham radio is a complex technical hobby. It's not something where you buy a radio, toss it on the shelf and assume it will be there when you need it. Making it work requires knowledge and practice. Unless you are going to commit to all that, it's not a good solution. Even with that, it's not a good solution.
2. Other than the idea of HAM radio as a hobby, would I need more than a Tech level license for the purpose I've mentioned?
Thanks for any feedback.
The license class doesn't make that much difference unless you are doing long range high frequency communications. That's all well and good, but again, no requirement that anyone be listening or even help you.
If you are looking for a communications solution for EMERGENCY use, you only have a few legitimate options:
Cell phone. Call 911 if you need help. You'll get a professional that is there for the exact purpose of helping you. That dispatcher will get your location data and know where you are, and where to send help, even if you don't know exactly where you are. They will dispatch the right professionals to help you.
Land line is still a legitimate solution depending on your location. If you are concerned about AT&T stopping the "provider of last resort" service, make sure you understand what that means before assuming they are going to take away your service. A 911 call from a land line will get to a professional dispatcher that will be there and will get your location information, even if you cannot provide it.
A satellite phone is a good option, but it is expensive and not a good solution for a "put it on the shelf and only use it in an emergency". the phones are expensive and the service is expensive. You also need to call the direct phone number for the dispatch center. Calling 911 form a cell phone will not necessarily get you to the right place.
For true emergencies, a Personal Locator Beacon is a good option. About $250 for a new one and no ongoing charges. It —only— allows you to trigger an emergency beacon, but someone will get that along with your GPS location and send help. PLB's require periodic battery replacement that needs to be done by an appropriate shop.
One of the better options is a small satellite beacon. Garmin InReach is a good choice. It's a small device that permits two way text communications through satellites. It also has an "SOS" button that will get you help similar to a personal locator beacon (above). The devices are $250 and up and require a monthly service. I pay $12/month for mine. I can send a few text messages a month for that price.
Newer cell phones have satellite capability and will allow you to send SOS emergency type messages via satellite. It's a good option and would be something you'd carry with you anyway.
Something like a StarLink device would be an option, but again, a solution that gets expensive.
I've been a ham radio operator for decades. I also work professionally in the two way radio industry. I've tried using amateur radio in emergencies and it has never worked. Not once. Even when talking to another ham, they often don't want to get involved. It's not a reliable solution and don't let anyone tell you otherwise. I have access to amateur radio, GMRS, a satellite phone, and many public safety radio systems. When I go out of range of cell phones, I carry the Garmin InReach device that I mentioned above. It's the right tool for me for emergencies.
