had my 2B/2BQ since the 1980's great ham band receiver
Deletenow i m finished listen .....thanks Bill and Pete.complimenti ,bravi ragazzi :)
ReplyDeleteanother great show. Cant wait to hear more about the Simple-Cever. if a book is coming out, I want one. Already bought a few SI5351 breakout boards from AdaFruit to have on hand. Aj4UM
ReplyDeleteHi Bill,
ReplyDeleteTweaking --- adjusting for effect
Majik smoke --- too much tweaking can release this
Scratch and daub --- tuning stripline and microwave stuff
quite literally by adding copper or foil or removing it.
Drilling and blasting --- mechanical construction
smoke and majik --- descriptions that are less than scientific and a bit obscure.
Turning the circuits knobs --- In the design of a circuit you can vary its behaviour, bias, tuning, and so on. See tweaking and also magik smoke.
One I've used for decades is... hexperiments, the "h" must be there and its about invoking the hex of math and science
in an experimental project. As in, a successful hexperiment.
Jacki Gleason used it fist and Fred Flintstone was somewhat modeled on the Honeymooners which came first. The grand Poobah and to the moon Alice stick in the mind.
Filters with less than 5-6 crystals tend to have seriously soft skirts. Its a limitation of how much selectivity you can get from four crystals in a filter.
That leads to now that receivers have reached a level that is very high we now need to talk about transmitters and the
RF baggage they produce.
An old term from a hardware hacker of some four decades back. Moving bits is easier than moving wires. I started both moving wires (hardware design) and moving bits Software development. The moving of bits is expansive
as you can go further. That and tweaking bits is less inclined to loose the majik smoke. ;)

Hello Bill and Pete,
ReplyDeleteGreat episode! When you were talking about how it will be hard or impossible to work with some of the small smd chips that are replacing through hole components I remembered a video I saw on hackaday who made a video of himself making a gps enabled geiger counter. He is working with a chip with extremely small pads, wiring it up point to point with enameled wire. It is a very cool build to behold! You always speak of Vlad; well he is alive and well, although in this case his name is Shibata. I worry about the disappearance of bigger, easier to solder chips too, but then again, we are a resourceful bunch and if we really want to put something together, we will find a way. And some of these chips can do amazing things! Here is a link to the video:

Here is the hackaday write up:

Thanks for all that you both do to promote the radio ARTS :-)

Bill/Pete,
ReplyDeleteThanks for the plug and nice comments on my videos. I just posted the "part 3" video on the 2B this weekend, including the last of the obvious repairs and some on-air testing. All I need to do now is touch up the alignment...
73,
Alan
Hey Bill and Pete
ReplyDeleteI'm pretty sure Grand Poobah is derived from the character Poo-Bah in Gilbert & Sullivan's opera Mikado. Poo-Bah was a high ranking official in the Chines court.

Bill and Pete,
ReplyDeleteAloha. Great Show! I got the "free" copy of SolderSmoke and am enjoying it immensely. It has sparked the Knack-o-matic engine in my brain to on and now I have this "need" to solder things together. HI HI
I am really looking forward the simpleceiver and definitely want to try and build one.
