QRP Parts Catalog

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.

ProductDescriptionWhat it's useful for
T50-6 Iron Powder Core Toroids (qty 10)Filters, 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 SwitchPretty 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 connectorsAn 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.
1N34 Germanium Diode Many radio projects call for the 1N34 Germanium Diode. Excellent for an RF probe too.
DC 12V Coil DPDT 2NO+2NC 8P Relay (qty 10)Replacement relays for the BITX40 and uBITX radios, also great for general 12v relay needs.
Variable Bucking transformer, 12V or 24V to 0.8-17V (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, StandoffUseful for mounting PCB's in their cases, while electrically isolating them.
8 Pin Microphone connector set (qty 5) If you're building something that needs a microphone, you'll want this connector. Compatible with ICOM and Kenwood, probably more.
30 Values 1% Resistor Kit Assortment, 1/4W Metal Film Resistors 100 220 1K 2.2K 4.7K 10K Ohm, PoiLee 600pcs Electronics 10 Ohm-1M Ohm 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.
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.
Piece 70 x 100 x 1.5 mm FR-4 Single Side Copper Clad PCB Laminate Board (qty 5)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!
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.
2Pcs black 36mm Top Rotary Control Turning Knob for Hole 6mm Dia. Shaft A good knob for potentiometers, rotary encoders, and variable capacitors
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
