content: Yep, Korad can make good power supplies. They got off to a rough start with the early youtube unit and they aren't all the way there yet but their current units can be reliable and pretty accurate. The current single channel models can be calibrated by the user, not sure about the multi-channel units but maybe they can also be calibrated by the user. I have a hunch Korad's next generation of products will build upon what they have learned entering the market. Another thing going for Korad (beside the price and features) is SRA Soldering Products. SRA is a very good distributor of their products - it's been a very positive experience doing business with SRA and they stand behind Korad's products.

content: I'm going through the old videos and I saw Dave's comments about the eTrex GPS being on the market for so many years. Well Dave, if you were impressed by how long that piece of consumer gear was on the market, take a look at the Sony ICF-2010 shortwave receiver. Sony finally quite selling it several years ago, but it had a run of almost 20 years. I suspect that is a record for consumer electronics.For a relatively affordable, portable SW receiver, it was simply the best one for all those years. I had one that I bought in 1986 and loved it. I finally sold it just last year, since there hasn't been much to listen to on SW for some time.

EEVBLOG #451 Scope is actually DS2202 not DS2072 - any issues in comparison? - Page 1
Forum section: electronics / general

author: cube1us
author_rank: Contributor
timestamp: August 12, 2013, 08:56:10 pm
content: Am in the market for a new scope over the next few months, so have been looking at the reviews. This DS2072 looks really nice (would be hard to buy a DS1102 or even an Owon 7102 now - which I had been thinking about given its larger screen and deeper memory). But I noticed that the scope that Dave actually used in the review is the DS2202 (200 MHz), not the DS2072 (70 MHz). Are there ANY differences aside from bandwidth? In particular, with respect to noise, etc.? What say you DS2072 owners out there? Thanks.

So if you have to ask if it's worthwhile to support because you want the extra content, that is not the right way to think about it.I may put something in there occasionally, but really it's just an extra perk for those who donated before and just got a thank you. It may come in useful for something down the track, and you can ask questions in there where I will certainly see them, instead of the main forum where stuff gets lost easily.

Also explain us an example of how to design a PID controller for fast response system like power supply. I already did PID controller using micro controller in my PID temperature controller solder station and it works just fine. But in fast response system I struggle with the problem of overshoot. Please sir and also suggest a standard book for PID controller.

Good spectrum analyzers also have very good dynamic range.What might be interesting would be to make a spectrum analyzer by connecting something like a modified satellite or cable TV tuner to a low cost scope and having a PC control the whole thing. (Add further stages of downconversion and you might be able to use a sound card, although it would take longer to perform a sweep.)

Actually, I do prefer 18650 more than lipo pack, unless Dave would implement something like a "flat clip" to hold the taps of the the battery pack instead of soldering, so changing/replacing battery wouldn't be a hassle...(yeah, lipo pack is much safer, but changing/replacing a lipo pack can really be a hassle, soldering/de-soldering, taping, padding, etc....)Anyway, I know the thing wouldn't be available soon as Dave said during the recent live contest video...just wondering...PS: if the info in the uSupply page is still right, then 2x18650 really doesn't seem good..I mean..the capacity...4~6 would be nicer, or maybe just fill up the space of the case lol~PS2: this is my first post..and I somehow clicked the "Request another image" button....ouch..it refreshes the whole page rather than just the image....Well, I did copied before hitting any button as I know such things can happen...

Most are long slender sticks; I would simply construct a channel behind the casing, where the LiPo is attached with a wide band of velcro or so.

The 3 lobes bounce around.I would think this would be easy to see .. like the transmitter graphics that arepublished in the ARRL handbboks.Can someone with more experience suggest what I should be doingto set up analyzer?Much thanks all!--KC9KEP

That also means that if the heathkit drifts 1KHz your whole display will drift one or two divisions. You could try singe shot mode, I expect that the Rigol can do that. At least the display will not bounce around then.
