radio kit

Well the 50 MHz version is the same 'scope, slightly crippled, and cost's ~$50 less. (most of time the extra BW isn't needed.. and when it is you then need lots more. :^)

You really need to cover your trail better, and you're just a pathetic old man with nothing better to do than post snide comments all over the internet under numerous aliases.

Yes it crossed my mind as soon as I saw the selection guide on this page:

That you could likely turn some into others just by changing the firmware.

That led me to

I hadn't seen the video though.

bloggs is too stupid to look at a poster's email address and use a tiny bit of deductive reasoning. I made no attempt conceal the source of my posts.

you first.

You post through eternal-september and you call that no attempt to conceal the source of your posts? Makes no dfference, you're a stupid little nothin g of a non-contributor. Google has a single click search of your posts unde r your fake alias, it's all snide useless off-topic commentary. You bring n othing to the table here, just go away and stay away, you're a lifeless non

-entity in real life and you're a lifeless non-entity here.

You really can't conceal your propensity for being a parrot, I'm supposed to tell you to drop dead first.

In my opinion there is nothing like an 'analog' scope, if you have one hold on to it. I have used Ferry X Pensive digital scopes, hey I even worked at Tek, but most digital scopes are just silly jokes. Apart from storage, and some fancy math, those digitizers do not in any way show reality. In fact the artifacts are so that a beginner, like a school boy for example, may have a hard time interpreting what the waveform REALLY is. And for that sort of thing (teaching) you do not need GHz sampling either, hey you are looking at a 1MHz AM radio. Old analog scope from ebay... I am still hanging on to my now almost 40 years old Trio 10 MHz, it is in use every day, strange that I sometimes build several GHz stuff.... And NEVER in all that time did I even feel the need to get a digital, or even storage, scope. H*|| I do not even have a multimeter I use my pinky for volts and my tongue for amps, or was it the other way around...

Yes I'm not about to get rid of the Hameg. The only reason for going digital is to get something small enough to take into a school. I still use the Hameg a lot. The latest patient is a Yorkville MM4D powered mixer. The owner says it hums. I haven't opened it yet.

PS, why not build a scope with the kids?

It takes you into: electronics design assembly programming math how a scope works (amplitude versus time) PC communication logic levels, hardware, reading datasheets FFT and how to calculate it and FFT windowing trigger modes LCD drivers, LCD backlights, character generators, AD conversion, analog mukltiplexers, sample and hold, etc etc

You can have classes for a year, some will drop out, maybe one will make it, and later start posting here.

It is great for audio, it shows higher frequencies aliased too :-)

I'm sure it works fine but probably a bit complex for one hour per week with one little guy.

Looks like you're as bad as me for getting solder flux on a schematic, or is that coffee?

I could probably take my MK14 into the school but it's a bit fragile.

That is true, but you never know..

Solder, those sketches are my building plans, and I solder things together on it to protect the table... Paper is a great thermal insulator, I use a paper towel to clean the soldering iron tip.

Never used that one, I remember a Motorola maxboard (6502) from those days. At work we had a commodore pet200 (BASIC) in those days:

Later (1980) I bought a Sinclair ZX80, and then a ZX81, nice BASIC.

I had to build my own keyboard to get the MK14 to work properly. So I avoided further Sinclair products and moved to a UK101

I've used PDP11 and VAX in other places.

Interesting, never used those computers

A bit later in the 1980 I wrote some business software for the Sinclair ZX81 to print repair bills for my TV repair shop, quickly got a 64 kB memory module, and added serial printer support so I could print the things (RS232 portable battery operate serial thermal printer) even sold some copies of that software / hardware.

Then a bit later when I stopped the shop, I worked as IBM PC card designer,, That was ISA, designed all sorts of interface cards, audio, industrial control mainly, theater lighting, what not, graphics...

At that time I had that Z80 system that is described on my site with many extension cards at home... running my own CP/M clone, kept it for many years, At some point it was faster than that 'new' IBM PC with its 5 1/2 inch floppy, I used a RAM disk.... MUCH faster, even on a 4 MHz Z80.

I was working with the IBM PC all day, writing software and testing hardware, we were close to IBM actually across the street so to speak. In those days I never wanted an IBM PC at home, 286 came, 386.... Was not very happy with MSDOS either,

Finally one day I bought a 486 with Win 3.1, trumpet winsock... internet, Then one day I got hold of some CDROM that had Linux 0.98 on it, That was it for me, no more Microsoft.

Running Linux ever since,

I have some win 98 on some old partition of an old server...

Yea, old days..

Ah TV repair. Did a lot of that in my early teens before I knew that there was such a thing as digital electronics. Now there is very little to repair and only someone my age will touch anything made in the 70s.

My web and email server runs Debian. Everything else is Windows.

I was one of the first with a color TV set in my country, those were VERY expensive back then. Repairing those sets could make good money. Color TV started here only in 1967, PAL, Quality was hundreds times better than US NTSC (stands for: Never Twice Same Color). Later the market got flooded with 400 $ or so sets from the far east, and you could not charge a lot for repairing that, and those were more difficult to repair if you could get parts at all, So at one point, and we had 4 or 5 people at work, I decided to say goodbye.. also differences of opinion how to proceed. One guy went into the furniture business IIRC, and a year or so after I left it was all over for them, it ran on my papers (license) I think they never got that paperwork... :-)

My webserver ran grml ( www,grml.org its is debian based, but now only a live CD... pity. ) but is now hosted at godaddy,com, too many attacks and things to watch out and keep updated (DNS, etc).

I still run a local server, but have taken it of the net for this IP. Now I send the data on SDcards by my 160 km/h drone ;-) NSA keeps looking,,,,, ;-)

Diamonds,,,, cross border... LOL

It is such a joke, that media show.

About the same as a small vehicle. I had a Beovision 3400 for a few years. It made a good room heater in winter.

Roughly the same as where I was at the time.

I worked in the USA for many years. I guess the technology had improved by then. As long as you had cable I thought that the pictures were reasonable on most channels. The higher frame rate helps. But I did miss teletext.

These days I'm frequently asked to repair computers (start from an alternative boot drive and get the viruses off) but I can't charge more than $100

Yes a server which is never updated might last 6 months before being compromised. Apache/PHP/MySQL works well on windows 7 for web development as long as everything is kept up to date.
