Enjoyed every bit of your post.Much thanks again….

Amateur Radio on the other hand is almost never Broadcast. It is designed for point to point Communication and is usually between two parties. It uses spectrum in several bands, such as:
HF. These bands have long distance capability due to ionospheric reflection.
10 meters – 28–29.7 MHz
12 meters – 24.89–24.99 MHz
15 meters – 21–21.45 MHz
17 meters – 18.068–18.168 MHz
20 meters – 14.0–14.35 MHz
30 meters – 10.1–10.15 MHz
40 meters – 7.0–7.3 MHz
60 meters – 5 MHz region
80 meters – 3500–4000 kHz
Medium frequency
160 meters – 1800–2000 kHz
Low frequency
136 kHz – 135 – 137 kHz

Also used are various VHF, UHF and SHF bands. These bands are useful but are limited by only being line of sight. They are used for various modes such as Television, EME (Earth, Moon, Earth), Satellite, etc.

In order to be able to use these bands, an operator needs various things. Top of the list is a License, provided after the prospective amateur satisfies the Government requirements, which usually consists of a test and paying money. He or she will also need the specialized equipment to be able to transmit and receive on those bands.

Hope these links help you. Goodluck!

Getting a license requires a written test, given by volenteer examiners. The test has 35 multiple-choice questions that are selected from a pool of a few hundered questions. There are three license classes, each requiring a test element. Study materials can be obtained from the Arrl website, or a local amateur radio store (if one is in your area). There are some materials you could get online for free, just look around. You’d want materals to study for the “technician” class of license, as that is the entry-level.

I have made simple connection cables several times using headset jacks and plugs and then small “pig tails” to other connection sizes. You can order the jacks online from any avionics supplier. I have yet to get any aviation headset to simply plug and work with Icom, Yaesu, Kenwood, or any rig that I had on hand. Adding the matching circuit allowed them to work but the exact match was different nearly every time. Without looking up the specs, I believe the aviation headphones will be 600ohms and the mics will be high as well(?) nearly all the “ham” units are looking for 4-8ohm headsets and low-impedance mics or amplified systems.
There is even a difference in military and GA as well as Helicopter headsets! Military units come closer to “ham” matching.

All that being said, there are “pre-made” cables from several sources Pilot USA has some on a quick search http://www.pilot-usa.com/adaptercables.htm

There are some schematics on line for matching “boxes” and values of R/C needed. I think I found some last time at http://eham.net ??

Good Luck

They will tell you they’re looking into it and then get back to you in 10 years time and tell you there was no evidence.

There is HUUUUUGEEE difference between Ham radio and CB radio.
They are not to be confused.

In fact , there are so many differences it would be hard to list them all on a simple answer., but the basics are this….

In most places , CB radio operation is allowed at no license cost.
That however doesn’t mean license free.
By transmitting on the CB bands , operators thereby agree to the terms and conditions set out for the use of the band by the spectrum management authorities of the country that they are in.

This means that there is rules and conditions , and penalties for illegal operation on the CB band.

On the other side of the equation Ham radio operators must pass quite involved tests to prove their technical proficiency and knowledge of radio and electronics theory and practice.
Then they must pay yearly fee’s to the government for the privilege of using the Ham bands.

Even with the license , Hams don’t own the bands or specific channels.
It is a shared resource that Ham operators know must be managed correctly so all can have a fair use of the spectrum.

If all Hams were going nuts doing what they wanted to , whenever they wanted to , the bands would be a mess , and completely useless.

This is in effect what has happened to the CB bands.
Due to lack of willingness by CBrs to follow the rules and do what is right , they have rendered their band either inactive , or just a mess of distorted signals.

In an attempt to limit interference to other services such as TV and radio , CB radios are limited in power output.

Ham radios have much higher transmitted power output.
Because of the education Hams have in radio/electronics , they can use this power and not cause interference to others.

So by far it is CB radio operators that cause interference complaints to be registered with the communications authorities.,,in fact , many 10s of thousands of complaints get filled against CB operators every year in the USA alone.

Another area where CB and Ham differs is in the types of transmissions that can be made.
CBrs are limited to voice only modes , where Hams can use Morse code , voice , and a variety of digital data modes.
hams can even transmits TV type of pictures around the world to other Hams , and even relay their transmissions through satellites.

This here is just a small example of some of the many ways Ham radio and CB radio differs.

If I had to pick 1 thing that is the biggest difference between the two , I would say it must be the education and mindset of the people involved.

CBrs are nothing like Hams., and they never will be.
