Qn1) Could someone recommend list of electronic components that i should
stock up on for starting my radio projects? 1.1) any links of such lists on the web available ? I wanted to order stuff from various sources like digikey etc. I dont want to be at a loss of components when i start experimenting. |

First, could you answer a few questions to narrow the field a bit.
Are you primarily interested in building radios? Transmitter or receiver? Accessories? What frequency ranges? Tubes or solid state? Interfacing to computers or standalone projects? What level of experience do you have and what are you starting with? Sounds like a lot to ask, yes, but it really does make a difference. If you go out and just start buying things, you can put several hundred or (if you go overboard) even a thousand dollars into parts without really being able to build much. For most experimentation, a decent selection of resistors and capacitors is pretty essential, but the actual ranges of values of each is considerably different depending upon what type of projects you have in mind. Likewise, diodes, transistors and other semiconductors. There are some "standards" but it really depends upon what you are planning. These days, there are a lot of projects involving logic, and you can really spend a fortune restocking for logic projects if you don't know what you want yet... When I started oh so many years ago, I began with a full assortment of halfway carbon composition resistors, along with a couple of capacitor assortments (disc and tubular). Now, most of the resistor values I have are quarter watt carbon film types, and the capacitor assortments comprise three or four different types and several voltage ranges. Diodes range from small signal types in germanium and silicon, along with the 4001-4004 1 amp general purpose types. For transistors, an assortment of common pap and nun devices (such as 2n2222a, 2n3906, 2n3906 and so on), plus a handful of various ICs and pampas that are used often. Often, people that don't have a fairly well stocked "junk box" begin with kits or published magazine articles that are of particular interest, then go on from there, expanding upon the parts they purchase for each kit or published project as they go along. Whenever I make up an order for a particular repair job or project, I always add a few other things to the order to round out what I was missing the last time I had something I needed to do... It helps to reduce the average cost per part due to minimum order size or high shipping charges. Of course, beyond just the parts will be some general equipment, such as a variable power supply or two, a decent DVM, and possibly an oscilloscope, depending upon what you are building... Don't forget to buy a good soldering station (the Welder WTCPN or other similar models come to mind), some solder wick and a good solder sucker. Having a quality, temperature controlled soldering station will make soldering so much more convenient you'll be able to do a really good job with a lot less practice. Of course, a good quality small diameter flux cored solder is essential. Then there are hand tools like exact knives, wire strippers, diagonal cutters (dikes), needle nose pliers, tweezers, screwdrivers, nut drivers and the like. The list (seemingly) goes on and on. Good luck! --Rick haricot wrote: Qn1) Could someone recommend list of electronic components that i should stock up on for starting my radio projects? 1.1) any links of such lists on the web available ?

sorry not to have been specific.
Are you primarily interested in building radios? Transmitter or receiver? I am starting with recievers. Basically implementing projects from Experimental Methods in RF Design Accessories? What frequency ranges? Tubes or solid state? Interfacing to computers or standalone projects? What level of experience do you have and what are you starting with?

Accessories? What frequency ranges? Tubes or solid state?
Short wave recievers as i am not a HAM right now. Solid state to computers or standalone projects? Standalone |

Qn1) Could someone recommend list of electronic components that i should
stock up on for starting my radio projects? I wanted to order stuff from various sources like digikey etc. I dont want to be at a loss of components when i start experimenting. A range of the most common resistor values from 10R to 10M. A total of 500 pcs can already be bought as a "kit" from many shops. A range of common caps from 10pf to 220uf, but not all that many values. Perhaps a few of each decade (10p, 100p, 1n, 10n, 100n, 1u, 10, 100u) with a few extra in the range of 10p to 100p and 1n to 47n (values used for tuning/filtering). A slack handfull of general purpose transistors, such as BC547 (NPN) and BC557 (PNP). Op amps - 741, 324, 358, 386. A good tip is to visit your local dump. A telly, a VCR and the odd defunct transistor radio can be a goldmine, especially for mains transformers, coils, tuning caps, pots and even hook-up wire. MOST IMPORTANT - A catalogue from your local radio component supplier. You can't stock everything. The above will alllow you to assemble a few simple circuits, but for anything decent you will still have to buy/beg/borrw or .... Don't forget to ask them for their PDF library on CD. The catalogues usually give you loads of circuits, pinouts and data. If you are going to spend $15 on a small selection of components, do what you have done here and hint that you are going to buy loads of stuff, build loads of projects, and they usually give you all sorts of freebies.
