Antenna Testing; Cw Training - Yaesu FT-450 User Manual

YAESU HF/50 mHz Transceiver FT-450 User's Manual
9) Save this setting in the channel memory and remember where you put it.
You are now ready to go. Either dial in the frequency you want to initiate communications or
dial to look for someone calling.
Then next time you want to start up on the same band:
1) Set theshift, ATT, IPO, RF gain and AF gain as shown in section 8,
2) Restore the memory channel for this setting
If you plan to change frequency, nudge the MAIN dial to enter M_TUNE. Either dial in the
frequency you want to initiate communications or dial to look for someone calling.

Antenna Testing

It is very convenient to test the standing wave ratio of the antenna as seen by the transceiver right
from the transceiver itself. Adapt the C.S function to SWR. Turn off the antenna tuner. Select the
desired frequency. Then simply press the "VOICE/C.S" button and read the SWR on the meter.
The transceiver will drive the antenna with about 10 watts and automatically switches the meter
to SWR. If the reading is 3.0 or less, then the antenna system is adequate for use with the built in
antenna tuner.
Hint: I found it convenient to set up a channel group with frequencies near the lower and upper
ends of the bands I am interested in. I can then test my multi-band antenna(s) quickly selecting
frequencies from that group.

CW Training

To practice sending, simply set up for CW operation. F-press "VOX/STO" to disable the BK-IN
function. Any code sent with the key will now be audible through the speaker or headphones, but
no transmission will take place. When you are done, be sure to restore the BK-IN function.
For CW reception training, the FT-450 has a built in CW Training feature, which sends random Morse
Code five-character groups via the sidetone (heard in the speaker). The groups may be numeric, alpha or a
mixture of both alpha and numeric characters. This feature is a little strange as it is only available in
MENU mode. Simply enter MENU mode as you normally would for changing adaptation and select the
CWTRAIN parameter. If you followed the procedure in section 7, Adaptation, you should now see the
letter A, N, or M for alpha, numberic, or mixed respectively. You can change that adaptation at any time
with the "DSP/SEL" knob.
While still in that mode (menu blinking) press the "F■" button. The random 5 code group will be heard
through the speaker or earphones followed by a display of the 5 characters so you can check you work.
Repeatedly press of the "F■" button for new groups as long as you wish. When you are done, be sure to
exit the selection and MENU mode in the normal way.
