Step 1: Build the chassis. Including time to
unpack and sort hardware, this step takes
about 2 hours.
Step 2: Build the DC power distribution board.
Although this board is simple, it usually takes
about 5 hours because it is the first board and
you will be getting used to the assembly proce-
dures.
Step 3: Build the front panel board
and attach it to the preassembled
and tested controller, adding the
display, tuning controls and me-
ters. Total assembly time for the
front panel is about 5 hours.
Step 5. Build the three boards making up the receiver: IF Filters (left), Bandpass filters/preamp (middle), and Re-
ceiver board (right). All surface-mount parts are pre-loaded, so you only have to add through-hole parts. Each of
these boards takes about 4 hours to build. You can even use the electronic layout files to help locate parts!
Step 4: At this time, you are able to turn on your Sienna, measure DC voltages and verify that the front panel
works. You can then experiment with the controls and even connect it to a PC and run remote control software
such as Ham Radio Deluxe or DXLab Suite.
Step 6. Install the receiver into the chassis, one board at a
time. Each board is tested as it is installed. After installation,
the manual guides you through the simple calibration steps
using only a voltmeter and by dipping and peaking signals
on the S-meter. The transmitter’s oscillators are used as in-
ternal RF signal sources, so you don’t need fancy test
equipment.
If you bought a receiver-only Sienna, you’re done! If not,
you move on to the pre-assembled/tested transmitter board
and the 100W amplifier kit (about 5 hours). See photos of
these boards on the next page.
Total construction time for a fully-loaded Sienna is about 40
hours, roughly as long as it used to take to build a Heathkit
DX-100 or SB-100!
Sienna’s modularity makes assembly straightforward and fun!
