    HAM Radio Relevance Currently and Personal Reflections.

    The main point I was addressing about Ham radio is that it "used to be" that it was the ONLY way you could communicate with people around the world in different countries. Building your own RF gear was part of that "unique" experience of it all. One of those unique factors is GONE as now you can...

    HAM Radio Relevance Currently and Personal Reflections.

    Good that what you learned in Ham Radio has helped you gain skills for employment in companies. That is a practical reason for learning Ham Radio, otherwise, it offers no practical use except perhaps, what is always promoted as "emergency communications in disasters". Otherwise it is simply a...

    But do you have indoor plumbing and modern bathrooms ? :eek: You never mention it only Ebay, that is why I asked... Amazon IC kits: https://www.amazon.com/gp/product/B07V1PKDZS?ref=em_1p_0_im&ref_=pe_2313400_633680210...

    Thanks.. Do you have "Amazon" in Scotland? Have you seen their IC kits? Not promoting Amazon just wonder if you had looked at those kits.

    Best IC Assortment, both Linear and Logic.

    I know about the 555s. Surface mounts, I know what you are saying, as I described my experience with that fiasco....one sneeze and they are lost. I have plenty of other components including transistors, but not inductors. So you are saying there is not just a general kit or bagged assortment...

    Best IC Assortment, both Linear and Logic.

    I was just asking for some opinions on general assorted boxes of ICs, from a parts distributor that would be adequate for what I described, both logic and linear....."general assortment" are the key words.

    Best IC Assortment, both Linear and Logic.

    Which ICs (identification numbers & group) in an assortment box (Amazon, Ebay etc) would be adequate enough to cover most applications for comprehensive useage for learning and hobbyist about ICs?

    Who Here is into Arduino & Raspberry Pi. Are You Also Serious About Electronics?

    Thanks for your advice, and I am considering what you say since you seem to know the ropes. As I told you some of this before, I was always interested in electronics as a teenager I was an aspiring Ham operator then, but mainly a SW listener, and I built that SW unit from a Heathkit type...

    Who Here is into Arduino & Raspberry Pi. Are You Also Serious About Electronics?

    My apologies for not accepting your reply as the final and indisputable conclusion on the subject.

    Who Here is into Arduino & Raspberry Pi. Are You Also Serious About Electronics?

    It would seem that the answers would be different since Microcontrollers are more advanced and contemporary than regular electronics, and are software - programming based, which opens up more possibilities than hard wired electronics circuits. More "possibilities"..

    Who Here is into Arduino & Raspberry Pi. Are You Also Serious About Electronics?

    Underlying these questions is the significance TODAY of these Microcontroller devices, compared to the significance of Pure Electronics, although they are related. In other words, a lot of non-electronics people are into Arduino project "Making", with minimal electronics knowledge and are...

    Swapping Out Boards, Repairing and the Economics Considerations Involved

    Good information there on "Time is Money" I guess my main concern is the value of jobs related to real electronics. especially as software takes precedence. Robots stuffing boards and wave solder machine advancement is making electronic systems cheaper and cheaper to replace without much need...

    Swapping Out Boards, Repairing and the Economics Considerations Involved

    One issue with repairing electronics is the cheapness issue. Even back 25-30 years ago I worked at a company that made electronic financial related machines. When a component went bad fixing it was considered a waste of time and money. The whole board it was on was swapped out and replaced. The...

    HAM Radio Relevance Currently and Personal Reflections.

    I referenced several times now Hams who can build their own gear as being very significant and as one of the big aspects of Ham radio that is most important to Hams currently, so I am not missing the point. I see that a lot of Hams do buy fancy off the shelf digital transceivers, and just go for...

    HAM Radio Relevance Currently and Personal Reflections.

    With that inexpensive and simple 5 watt transmitter, you could communicate thousands of miles at night with CW and it was "exclusive" to Ham radio only. Now it is not exclusive anymore. Anyone with an internet connection can communicate around the world and that was my point. Of course...

    HAM Radio Relevance Currently and Personal Reflections.

    That is a good comparison but the difference is that listening to music is a passive act. Ham radio is very involved and requires serious participation. As I said, it used to be, back in the day, the only way to directly communicate (in the moment) with people, except for maybe telephone, but...

    HAM Radio Relevance Currently and Personal Reflections.

    As I remember QRP is basically CW, and was the lowest level Ham license you could get back in the day but maybe I'm incorrect about that. I remember an old Amateur Radio magazine showing how to build a 5 Watt transmitter for CW which I had my eye on, I had a key and learned Morse Code with an...

    HAM Radio Relevance Currently and Personal Reflections.

    I remember way back before the internet or even home computers having a Ham Radio setup was really phenomenal. A Ham I knew just down the road had a 6 Meter transmitter in a large cabinet in his garage that almost looked like a small commercial radio station that he built from scratch and an...

    Oscilloscopes:2 Channel, 4 Channel, 100Mhz, 500Mhz etc.

    Thanks for your advice. I used a Tektronix like this one in college. Tektronix 475 Dual Channel Oscilloscope with Service Manual | eBay What if I come across for example, a 100 MHz close to the price of a 20 MHz as you recommend? should I pass it up and go for the 20? Are are you saying that...
