To go back to the Original Posters question, can there be a way to change the gain of a 4558 Op Amp...

The response was two fold, the way it interprets the question related on an object - in this instance two one being the Radio board it's used in EPT 3600-XX series and the 4558 Op Amp - specifically the Mic Amp section.

It would not have any real clue as to which section of the 4558 chip is being used as a Mic Amp - we know by research and thru understanding of pictorial representations (schematic symbols and circuit design) being as complex and flexible as it is, the Op amp and it's functions are of two different meanings - one side of it is used as the TX / RX switch - which is one side of a dual - function device and the Mic amp is the other half.

Secondly the response was also based upon previous dialogues from it's references (to what it has access to - is not known - presumably the entire internet and any searchable text on 4558 Op Amp) - which may include this site as long as it has public access to it - versus privileged and proprietary information which it may not be able to view the subjects discussed in privately owned and fire-walled server repositories about the 4558 Op Amp.

So perhaps you would need to be more specific in the question to AI so it can then reference which pins and which side of this dual op-amp is what you're asking it to interpret.

You may need to have it look and review Pins 1, 2 and 3 and it's circuit design to see if it can be made more effective - it may also need the component designations Rxxx and Cxxx to identify the paths the AI can then research to help you sort this out.

Just so you know, many people think AI can be entertainment and a fun tool. It is a tool, but it becomes more powerful in the tooling it can provide the answers for - if you know how to ask the Right questions to get the right answers.

Many can just cut and paste a circuit design but if you redrew and submitted the one side of the op amp so it only focused on that - it may help.

A while back I did the same for "who sells the best capacitor kits". It now knows. But only if you talk to ChatGPT. The AI's don't play well together and don't share information.

Jeff -

I asked the same questions you asked but to ChatGTP. Here are it's responses:

1. Is the Connex 10 meter radio legal for a Ham operator to use.

The legality of using a Connex 10-meter radio for amateur (Ham) radio operations depends on several factors, including the specific radio model, its capabilities, and how it is used. Here are some key points to consider:

  1. Frequency Range: The Connex 10-meter radios are designed to operate on the 10-meter band (28.000 to 29.700 MHz), which is allocated for amateur radio use. Licensed Ham operators can legally use radios on this band.
  2. FCC Certification: In the United States, the Federal Communications Commission (FCC) requires that amateur radios meet certain technical standards. Some radios marketed as "10-meter" radios are actually designed to be easily modified to operate on CB frequencies (11 meters) and might not meet FCC Part 97 specifications for amateur radio equipment. Radios that can be modified to operate outside the authorized amateur bands are often considered illegal for sale and use.
  3. Modifications: If a Connex radio is modified to operate outside the 10-meter band, it may violate FCC regulations. Hams are allowed to modify their equipment, but it must remain compliant with the Part 97 regulations and must not be used on frequencies where the operator is not licensed.
  4. Type Acceptance: While amateur radio equipment does not require the same type acceptance as commercial equipment, it still needs to meet technical standards for spurious emissions and power limits as specified in Part 97 of the FCC rules.
To summarize, a Connex 10-meter radio can be legal for a Ham operator to use if it is unmodified and operated strictly within the 10-meter amateur band by a licensed operator. However, if the radio is capable of or has been modified to operate outside the amateur bands, it may not be legal for use according to FCC regulations. Always ensure your equipment complies with the relevant rules and operates within your licensed frequency privileges.

2. Is the World Wide Radio Forum the best radio forum on the internet?


Whether the World Wide Radio Forum is the "best" radio forum on the internet depends on what you are looking for in a forum. There are several popular forums that cater to different aspects of amateur radio and may suit different needs and preferences. Here are some notable radio forums:
  1. QRZ Forums:
    • Pros: One of the largest and most active forums for amateur radio operators. It covers a wide range of topics including equipment reviews, technical help, licensing, and general discussion.
    • Cons: Due to its size, threads can sometimes become cluttered or go off-topic.
  2. eHam.net:
    • Pros: Offers a vast amount of information including product reviews, articles, and forums. It's a good resource for both beginners and experienced operators.
    • Cons: The interface is somewhat dated, and the forum can be less active compared to QRZ.
  3. Reddit’s r/amateurradio:
    • Pros: A modern platform with a mix of new and experienced operators. It's user-friendly and often has timely discussions on current topics in amateur radio.
    • Cons: Reddit's format can sometimes lead to shorter, less detailed responses compared to traditional forums.
  4. The World Wide Radio Forum:
    • Pros: Known for its focus on both amateur and CB radio, it attracts users interested in a wide range of radio communications. It can be a good resource for niche topics.
    • Cons: May not be as active or broad in scope as QRZ or eHam.
  5. Ham Radio Forum:
    • Pros: Dedicated to ham radio with a variety of sub-forums covering different interests within the hobby.
    • Cons: Smaller user base compared to QRZ and eHam, which can mean slower response times.
Each forum has its strengths and unique community culture. If you are looking for broad, active discussions with a large user base, QRZ and eHam might be more suitable. If you are interested in a specific niche within radio communications, such as CB radio, the World Wide Radio Forum could be a better fit. Reddit’s r/amateurradio is excellent for quick questions and current discussions. Ultimately, the "best" forum is subjective and depends on your specific needs and preferences.
-------------------------------------------------------------------------------
While these replies are somewhat generic, they are better and more detailed then what you got from META AI.
The quality of the replies you get depends heavily on what AI site you're working with.
Any site associated with META or Mark Suckerberg is substandard, worthless, and just exists to generate ad revenue.

This is wrong.
There is an exemption in part 97 rules that allows a ham to modify radios and use them.
We often modified CB radios for ten meters years ago, legal as ice cream.

In 2009 a retailer was fined $7000 for selling a Connex radio to two FCC field agents that he modified to transmit outside of the ARS frequency's .

When the FCC tried to enforce the collection of the fine he went to court and got it dismissed.
The engineer that designed the Connex testified that the radio was designed as a HF transceiver, and that ANY radio, with enough work, can be modified to work out of band.
The rule is that
You can not "Use" the radio to transmit on CB frequencies because CB radios must be certified to operate on CB.
As a licensed Ham you can build your own radio from scratch with no certification required.
It is the operators responsibility to use it properly.
He sold the Connex radio already modified ( yes it would tx on 27 mhz) and the Judge in the case dismissed the fine.

I can dig the case up if needed but it is legal for a ham to buy, modify, and use as long as he is adhering to power limits, emissions, and within his class of license regardless if the radio can transmit from DC to Daylight.
If this was true, every Ham radio sold by ARS, Gigaparts , HRO and other retailers would be illegal as soon as there service department opened the radio for full TX coverage.


It seems to me that these AI chat bot type search engines can be manipulated easily to give you the answer you want.
They answer with may, could, might or some other vague term that if they are wrong , it's ok because it said "may be illegal"
It's legal. Period.
I will still do my own research.
These things are another "tool" that I will admit "can" be useful, however they should not be taken as a final answer.
I agree that some of them are better than others, but nothing can replace a person doing his/her own research.

On Edit

I still think that WWDX.com is the best dam radio forum on the internet.

Looked through our ImageShack archive and found the schemo.

The 22uf cap in the diagram was changed to a 47uf a few years back. Sounded a little better. Feel free to use whatever size cap you think sounds best.


The connections are marked as seen in a Cobra 29LTD and similar models. The side marked "rear" will be the side of the resistor leading to the driver transistor. The side marked "front" will go to the side of R131 leading back to the banded end of D105 and also to the final stage's choke coil L108.

Because of a rouge Nestor3 there are now 4 laws of robotics.
He (the Nestor)put forth that if a robot dropped a heavy weight on a human, once the object left his control it was gravity that would kill the human being and not the robot.

Quote:
The laws are as follows: “(1) a robot may not injure a human being or, through inaction, allow a human being to come to harm; (2) a robot must obey the orders given it by human beings except where such orders would conflict with the First Law; (3) a robot must protect its own existence as long as such protection does not conflict with the First or Second Law.” Asimov later added another rule, known as the fourth or zeroth law, that superseded the others. It stated that “a robot may not harm humanity, or, by inaction, allow humanity to come to harm.”

These were written for robots, AI? Dont know.......

Asimov is legendary.....
