for clarity. They should be pulled tight to hold the two lengths of
speaker cable together. Trim any excess cable tie length.
Note: An extra .01µF bypass capacitor is provided with the
MISCELLANEOUS items that may be used if needed to suppress RF
pickup at your speaker terminals or at the EXT. SPKR jack. If you
hear loud clicks in the internal or external speaker when transmitting at
moderate to high power levels, you may need the bypass cap. [TBD]
Hole Covers
Hole covers for the accessory connector holes in the top cover and heat
sink were not available in time for field test. These will be supplied free
of charge to field testers when they become available.
Finishing Touches
Examine the control board one last time to be sure that it is
correctly plugged into the RF board. All three connectors must be
mated completely.
If you have not completed alignment on all bands, you may wish
to do so at this time.
Connect the frequency counter test cable to the BFO test point
(TP2). This will allow you to modify your filter and BFO settings if
necessary during normal operation.
If there are any missing chassis screws in the bottom cover, heat
sink, side panels, or front panel, install them now.
Plug the speaker into P5 on the RF board, just behind the on-off
switch, S1. The connector is keyed so that it can only be plugged in one
way.
Place the top cover onto the chassis and secure it using 8 chassis
screws.
