MR6 • 5 RAMSEY Learn-As-You-Build KIT ASSEMBLY There are nu m erous solde r con nections on the MR6 printed circuit board. Therefore, PLEASE take us seriously when we say that good soldering is essential to the proper operation of your tra nsmitter! • Use a 25-50 watt soldering pencil with a clean, sharp tip.
MR6 • 6 the solder (see the associated diagrams). Another commonly used technique is to glue th e surf ace mount components to the printed circuit board before soldering. The p rocedure is to take a s mall amount of glue (usually with a pin or toothpick) and “dab” the circuit board in the place where the component will be a ffixed.

MR6 • 10 Now, let's get building ! First, we’ll install the “normal” parts th at mount on the “component “ side of the circuit board w ith their leads pa ssing through to the “solder” side of the board. This will also help us to get ac quainted with the up - down, left - right orientation of the circuit board.
MR6 • 11 14. Install Q3, another MMBTH10L NPN surface mount transistor (marked 3E). Once again orient it as shown in the parts placement diagram. 15. Install R8, 100K ohm chip resistor. This completes the frequency multiplier portion of the MR6.
MR6 • 12 CONGRATULA TIONS You have just co mpleted your MR6 mo del rocket tracking un it. Take a well deserved break now . Give your eyes a rest. W hen y ou return, be sure to check over your work on the entire circuit board. Ene rgizing the circuit board with solder “ bridges” or m isplaced c omponents can damag e y our kit.
MR6 • 13 DATA INPUT IDEAS: The easiest way to use your MR6 is to tune your 2 meter scanner or receiver until you hit the “dead spot” indicating that it is receiving the carrier from your kit. Turni ng the MR6 off will confirm that you’re on the right frequency.
MR6 • 14 CONCLUSION We sincerely hope that you have enjoy ed the construction and use of this Ramsey Kit. As always, we have tried to compose our manual in the easiest, most “user friendly” format that is poss ible. As our custom ers, we value your opinions, comments, and additions th at you would like to see in future publications.
