optional installation and would allow low loss Multi-brand operation. 8-32
stainless steel washers and nuts required.
*For a convenient way to lower the operating frequency on the 40M band, please
refer to Figure No. 2 where the installation of the stub tuning wires are shown.
Please cut a 6-ft. length of wire into two equal lengths. Install one of these wires
under the innermost nut on the ISO-RES coil. Repeat this for the ISO-RES on the
other side of the DX-CC. Trimming these two stub -tune wires will allow the user
to adjust the 40M resonant frequency to the point desired. To raise the operating
frequency on 40M, the main 40M wires must be shortened as necessary to reach
resonance.
Remember to strip the insulation from the connection end of the stub tuning wire.
* To lower the operating frequency on the 80M band, a small length o f wire may
be soldered to each side at the ends of the DX-CC. These ends may then be
trimmed to achieve the desired operating frequency. To raise the operating
frequency on 80M the 80M wires must be shortened as necessary to reach
resonance.
*The DX-CC may be operated on the entire amateur HF bands with the
incorporation of a good antenna tuner into the system! Using the antenna tuner in
the system will allow full operation WITHOUT ANY MODIFICATION OR TUNING
OF THE DX-EE!
*If a tuner is to be used in a multi-band arrangement (all HF bands), a
recommended alternative arrangement would be to short the shield and center
conductor of the coax at the transmitter end, then connect as "long wire" to the
random wire output of the antenna tuner. This system has worked very well
during our many tests of the DX-CC. For these installations the antenna tuner
must be well grounded.
*Periodic clearing of the drain holes near the SO-239 connector will reduce build
up of residue such as spider webs, etc.
