Building Instructions:
1. DO NOT remove any parts from the kit until instructed to do so.
How to wind Toroids for this kit.
2. Some helpful SMT Info / Links
Surface-Mount Soldering Notes by W8BH, Bruce Hall Youtube Link About Desoldering And Flux Youtube Link About Capacitors Youtube Link General SMT Tutorial Youtube Link Hot Air SMT
3. Try to limit the handling of the SMT parts; they have a tendancy to disappear.
If using a hot air gun, you may wish to organize the parts installation into sections.
4. Install the unmarked capacitor
_____ C3 - 1000pF - qty 1 - install and solder.
5. Install the two SMD 1206 resistors.
_____ R7,8 - 51Ω - qty 2 - labeled as 510
_____ R1,2,3 - install any optional LO Port Attenuator Resistors
_____ R4,5,6 - install any optional RF Port Attenuator Resistors
_____ install jumper wires across R2 and R5 if NOT installing Attenuators
6. Install MiniCircuits ADE-1 or ADE-6 Mixer.
Note the DOT at PIN-1 - should be installed near R7
_____ ADE-n - install and solder.
7. Install any 3-Pin headers onto the PCB - NOT INCLUDED
8. Install Trimmer Capacitor
_____ C1 (C4 not required) - install the Brown Trimmer - Note Orientation
9. Create & Install IF Diplexer Inductor L2
L2 is a T37-17 toroid colored blue & yellow
Select your IF from the table and cut the required red magnet wire.
Wind wire evenly over the entire toroid.
Trim the wire ends to half an inch, then tin with solder and install on the PCB
Optional: Verify that L2 & C3 are resonant at the IF using a Scope/SigGen or a Spectrum Analyzer.

10. Create & Install IF Diplexer Inductor L1
L1 is either a black FT37-67 or black FT37-61 (see table)
The FT37-67 is in the SMD parts bag
Select your IF from the table and cut the required red magnet wire.
Wind wire evenly over the entire toroid.
Trim the wire ends to half an inch, then tin with solder and install on the PCB
Optional: Verify that L1 & C1 are resonant at the IF using a Scope/SigGen or a Spectrum Analyzer.
