Welcome to our QRP Parts Catalog! We’ve curated a list of things we use regularly as a quick reference for stuff you’re going to need for QRP experimenting and fun. Most of these parts we’ve used first hand, or something extremely close.
|What it's useful for
|Hilitchi 720-Pcs 0.1uF-100nF 24 Value DIP Monolithic Multilayer Ceramic Chip Capacitors Assortment Kit
|You're going to need capacitors. Here's some capacitors!
|1% 3350 pcs,134 Values RoHS Compliant Resistor Kit x 25pcs =3350 pcs (0 Ohm - 4.7M Ohm) 1/4W Metal Film Resistors Assortment
|What doesn't need resistors? Modifications, new builds, repairs- these things tell the electrons where to go as good as any, and it's a nice variety.
|100pcs 1N4148 Switching Diode Kit DIY Electronic Component Set Straight Pin DO-35
|Many radio projects call for the 1n4148 Diode. Excellent for an RF probe too.
|No Image Available
|T50-6 Iron Powder Core Toroids (qty 10)
|T50-6 Iron Powder Core Toroids are good forFilters, transformers, L-Match Tuners and more. Good for 3 MHz - 40 MHz in most cases.
|T130-2 Iron Powder Core Toroids (qty 4)
|9:1 transformer for End Fed Half Wave antennas up to 100W
|Hakko CHP-170 Micro Cutter
|The real question is- what ISN'T it useful for. You'll wonder how you lived with out this super cheap tool!
|AC 125V 6A Amps ON/ON 6 Terminals 2 Position DPDT Toggle Switch
|Pretty much everything that needs a switch. It's DPDT so it'll work in many different applications that call for SPST, SPDT, DPDT.
| Variable Capacitor 365 pF, CW Rotation
|What can I say, it's a variable capacitor. L-Match or T-Match Antenna tuners, Analog VFO's and more. 365pF is good for most projects.
|Chassis Mount SO-239 Connector, (qty 5)
|If your shack is all SO239/PL259 then you'll want these to replace the BNC's that come on many QRP kits.
|200pc Transistor kit BC337 BC327 2N2222 2N2907 2N3904 2N3906 S8050 S8550 A1015 C1815
|If you're going to scratch build just about anything, you're going to need transistors! This pack comes with enough to keep you going for a while and is far cheaper than buying specific transistors separately.
|2N2222 NPN TO-92 Transistors (qty 100)
|Maybe you don't need an assortment of transistors, you just need a boat load of 2N2222's. This'll work!
|50ft Rg8x with PL259 connectors
|An inexpensive way to get some cable. No, it's not Belden and the connectors aren't as good as higher end parts. It's also far less expensive.
|8x DC-DC Buck Converter 3A Power Adjustable Module 24V to 12V 9V 5V 3V (qty 5)
|An efficient replacement for the LM7805 regulator. Easy to use and doesn't get hot.
|180PCS M3 Nylon White Hex M-F Spacers/ Screws/ Nuts Assorted Kit, Standoff
|Useful for mounting PCB's in their cases, while electrically isolating them.
|Aideepen Mega328 LCR-T4 Transistor Tester Diode Triode Capacitance LCR ESR Meter Module MOS PNP/NPN M328
|This component tester is great for matching diodes (such as in the the DC40 build)
|24 AWG Hook-up/Antenna wire (100ft)
|I've used this wire for my G7FEK antenna and others. It's inexpensive and high quality stranded wire.
|10 Piece 70 x 100 x 1.5 mm FR-4 Single Side Copper Clad PCB Laminate Board (qty 10)
|Excellent for home brewing your RF circuits. For non-RF circuits check out the item below.
|5x7cm Double Sided Prototyping Board
|Using the Hakko cutters above you can make these any size you need, and get a lot of mileage out of them. Quite useful!
|Geekcreit® 40pcs FR-4 2.54mm Double Side Prototype PCB Printed Circuit Board
|This is the same thing as above, from a different manufacturer and from Banggood.com rather than Amazon. It's 8x the product for essentially the same price, but shipping takes a fair bit longer. Worth the wait!
|Arduino UNO Project Basic Starter Kit
|The Arduino is at the heart of many a QRP project, and this kit will get you started with the Arduino basics you'll need- plus, you'll have an Arduino to use!
|4" & 8" Nylon Zip Ties (200pc)
|If you can't glue it or screw it, zip tie it. 'Nuf said.
|RadioShack Project Enclosure Box (5 x 2.5 x 2 inches)
|A project box that is a nice small size but also has an optional metal faceplate
|Geekcreit® ATmega328P Nano V3 Controller Board Compatible Arduino Improved Version Module
|The Arduino Nano is the basis for many projects. This clone is cheap!
|SI5351 Clock Signal Generator Module GY-SI5351 High Frequency Signal Square Wave Frequency 8KHz-160MHz
|The venerable si5351 on an inexpensive breakout board.
|Excellway® EF01 Electronic Plastic Shell Cartridge Handle Project Case Desk Instrument 200x175x70mm
|A fantastic case for the BITX40 and uBITX radios or any other project really.
|Soloop 328pcs 2:1 Polyolefin Halogen-Free Heat Shrink Tube Sleeving 5 Color 8 Size
|Heat shrink keeps everything orderly and protected.
|Mustool® MT223 60W Adjustable Temperature Electric Solder Iron Welding Rework Repair Tool with 5pcs Solder Tips I/3C/4C/K/2.4D 110V/220V Option
|This is the very inexpensive version of my favorite soldering iron. Be sure to pick the version for your power plug!
