75mhz gear - Condition Red

Sounds cool, but I have enough of a problem keeping the subs going in a straight line let alone worring about shaft speed. Lol. BD

study for a week to take your Ham TECHNICIANS test (35 multiple guess questions), take test, pay your $10, you are good to go.

The FCC license is good for 10 years. You can renew the license on the FCC website at no cost. You don't need to learn Morse Code for the Tech license.

I renewed my Ham license 4 years ago on the FCC website, and had the new paper in a few days.

What do you initially have to do to take the test?
That is not a thing you can do online thing right? BD

Fee for test.
What I have found says $15.00.

It seems that everyone believes that the big bad FCC will pounce on an unlicensed operator of a 433 MHz R/C transmitter.
This is patently false. I hold an Amateur Extra ham license (the highest class) and have read the FCC Part 15 rules several times.
First, NO ONE CARES about a single low power 433 operator or even a bunch of operators at a sub event! The FCC does not have the resources to care (unless you are a manufacturer).
Second, the FCC Part 15 rules allow non-licensed operators to use 433 below a certain 'radiated' power limit. Estimates of this power limit go up to 5 watts, but I would put it at perhaps a watt or so depending on the efficiency of the antenna. You can even build up to 5 unlicensed low power transmitters for personal use without a license.
Third, whether you have a license or not, you can't interfere with another operator. No harm, no foul, license or not.
Now this all changes if you're selling rigs on 433. If you are a "manufacturer", you better know what you're doing and get your gear certified.

A friend who works at Boeing told me the very same thing. He and his two sons fly FPV drones. He said getting your license for such low power use isn't worth the effort. The FCC does not care about fractional wattage.

[bigdave]

This is true.
Chances are you would never get cought.
But I have friends that are Extras and I was told that if they cought someone not having a license they would blow their keister in in a heartbeat.
They are required to do it by law.
Like all the bozos you see driving around on their cell phones.
It's not allowed (at least in my state).
Sorry to be a Debbie downer! BD

The main advantage of 433/458mhz is that it has enough bandwidth for frequency hopping. That means like 2.4ghz, you don't need to worry about frequency clashes, you just switch on and go.

Having said that, I'm still rocking my 40mhz rig- it works well, and it's paid for. Would I consider going over to UHF? Possibly in the future, if my existing kit gives up the ghost, although with the reliability of modern electronics I'm sure I'll expire before the radio does. If I was starting from scratch now, I would probably go straight for UHF.

You are right, Dave. No way around it, but what are your thoughts what Vasily had to say about part 15 and fractional wattage? I read the entire thing through twice. I must admit by the time I got to the end it read to me like a really bad novel....I wasn't certain what it was I just read.

Here is a link to the Part 15 Overview:

Thanks Matt.
I will read it.

OMG
My brain hurts.
You would need a Philadelphia lawyer to figure it out. BD

No where near as bad as reading/writing patents (especially foreign ones). Bottom line from that whole document is 'maybe, it depends on who is enforcing it'. Typical of lawyer written technical rules. A lot of it rules directly on commercially sold products, not home made, but home made can be held accountable if it is shown to interfere with someone else who notices.

Dave, those were my thoughts exactly!!!
I looked at the example test tonight. It's pretty simple. I don't think there would be any trouble for just about anyone who is willing to spend a couple of hours studying to pass it.

A question for Tim S.
Are you running 433 in your Taranis E?
If so which module and is it involved? Thanks, BD
