Section 9 RX/TX Mixer, Low pass filter
The following transistors may easy be damaged by ESD. Dont
forget to discharge yourself, use a potential free soldering
station.
The three leads of the BFR96 should be bent carefully down, the writing
should be readable, when the transistor is in place.
[ ] T9 BFR96(S) E4
[ ] T10 BFR96(S) D5
[ ] T11 BF244A C/D5
For the mixer TUF 1 you have to be careful about short to the pc
board as with crystals. Mount it with the help of two pieces of cut
off resistor leads as help, and remember to remove them after
soldering! Remember to mount the mixer in proper direction. See-
ing it from below, note that the leads aren’t centred. At the component
side, you can see how to orient it. (Shown as the mixer as a transparent
object in the drawing).

Now a few diodes, check their value with a loupe, not to mix
them up.
[ ] D4 BA479 E/F3
[ ] D5 BA479 E3
[ ] D6 BA479 D3/4
[ ] D7 BA479 D4
[ ] D8 BA479 D/E4
Now the other type
[ ] D9 1N4148 F2/3
[ ] D10 1N4148 F2/3
[ ] D11 1N4148 F2
[ ] D12 1N4148 F2
SMCC RFCs are well known by now
[ ] Dr1 10µH SMCC F3
[ ] Dr2 47µH SMCC E3
[ ] Dr3 47µH SMCC D/E 3/4
[ ] Dr4 47µH SMCC E3/4
[ ] Dr5 10µH SMCC C/D 4/5
[ ] Dr9 10µH SMCC F3
and now a lot of caps.
