Vertex Standard FT-950 manual Split Operation Using the TX Clarifier VFO-A Operation

FT-950

Operating Manual

If you are using the speaker for monitoring, instead of headphones, excessive advancement of the [MONI] knob can cause feedback to occur. Additionally, this feedback can cause the VOX system to hang up in a loop, making it impossible to return to receive. Therefore, we recommend the use of headphones, if at all possible, or the minimum usable setting of the [MONI] knob, if the speaker must be used.

Because the Monitor feature utilizes a sampling of the transmitter’s IF signal, it can be very useful for checking the adjustment of the Speech Processor or Parametric Equalizer on SSB, and for checking the general signal quality on AM and FM.

Split Operation Using the TX Clarifier (VFO-A Operation)

For split TX/RX operation in “casual” pile-ups, where the split is less than 10 kHz, the TX Clarifier (Offset Tuning) feature may be utilized.

1.Press the [TX CLAR] button. The “TX” icon will appear in the Multi-Display Window in the display.

Quick Point: The Clarifier is frequently used for receiver offset tuning. However, for DX pile-ups where the DX station is using a split of less than 10 kHz, the TX Clarifier function is usually the quickest way to set the transmitter to the desired offset frequency.

2.Rotate the [CLAR/VFO-B] knob to set the desired transmitter offset. A maximum split of ±9.99 kHz may be set.

3.To exit from TX Clarifier operation, press the [TX CLAR] button once more. The “TX” icon will disappear from the Multi-Display Window.

Advice:

To listen to the pile-up calling the DX station, so as to find the station currently being worked, you may press the [RX CLAR] button. Once you have zeroed in on the station calling the DX (use the SPOT function on CW for precise alignment of your frequency), you may then press the [RX CLAR] button again to cancel the RX Clarifier, and return to reception on the DX station’s frequency.

Just as with receiver Clarifier operation, the amount of offset from the original VFO frequency will appear in the small display window.

As with receiver Clarifier operation, when you turn the TX Clarifier off the last-used offset is not lost, and will be available if you turn the TX Clarifier back on. To clear the Clarifier offset, press the [CLEAR] button.
