HF/QRP Remote Sensor Assembly Instructions

___

Wind T1 with 10 turns using the red and green #28 gauge wire. T1 is the small, black toroid just

 

under one half inch in diameter. See picture below and wind this in bifiliar fashion by using two

 

lengths of wire and winding them at the same time. It doesn’t matter if you twist them or wind

 

them side by side. Note: you must wind this in the direction shown in figure 2.

___

After scraping the insulation from the ends of all four wires, connect the green 2 wire to the red 1

 

wire and twist together. You will now have three leads: the red wire on the left, the twisted pair

 

and the green wire on the right. Do not install T1 yet.

___

Install all of the resistors, R1, 2, 3 and 4.

___

Install the 1N4148 diodes, D1 and D2. Note the band polarity.

___

Install 10 uH Chokes, RFC1, 2 and 3.

___

Install the .01uf monolithic capacitors, C1 and C2.

___ Install the ceramic capacitor, C3 100pf 1KV.
