INSTALLATION

Select a location for the DU 800 T that allows the

connectors to be free of any

possible contact during operation.

 

WARNING:

SOME BALANCED OR END-FED ANTENNAS WILL PRODUCE HIGH RF VOLTAGES AT THE BANANA CONNECTORS. RF BURNS MAY RESULT IF TOUCHED DURING TRANSMISSION.

 

INSTALLATION PROCEDURES

 

  1. Connect a coax cable from your transmitter or receiver to the RF INPUT connector on the rear panel. Keep the cable as short as possible. If you use a linear amplifier connect your transmitter to the linear amplifier output to the DU 800 T.
  2. Connect coax cable(s) from your antenna to RF OUTPUT connectors on the rear panel. These connectors are either direct from the transmitter or trough the tuned circuit.

 

BEFORE OPERATION

  1. To avoid possible damage to the DU 800T, set INPUT, OUTPUT, BAND SWITCH a switches as outlined in the next section before applying transmitter power. (Tuning Section)
  2. Begin tuning with your transmitter se tat a low power setting (50 to 100W)

 

WARNING:

DO NOT OPERATE THE DU 800 T WITH THE COVER OFF!

TUNING

 

  1. Select the band and frequency of desired operation.
  2. Set BAND SWITCH controls to the suggested settings before applying the transmitter power. Actual settings may vary from antenna to antenna.
  3. Set up your transmitter to a low power output. If you transmitter has a TUNE position, select that position.
  4. If you use a linear amplifier, set it to STAND BY. Do not use the linear

Amplifier until the DU 800 T is tuned.

WARNING:

DO NOT EXCEED 800 WATTS AVERAGE (SINGLE TONE).

 

  1. Rotate the INPUT and OUTPUT controls for maximum noise or signal as heard on your receiver.

 

  1. Key your transmitter and adjust the power level for a reading of 50-100 watts on the FORWARD scale. Adjust the INPUT and OUTPUT controls for a minimum REFLECTED reading while maintaining a FORWARD reading of 50-100 watts using your transmitter power control.

 

  1. Read the SWR on the red scale at the point where the two needles intersect. Repeat step 6 until the lowest SWR reading is obtained. The SWR should be 2:1 or lower.

 

NOTE: This procedure takes patience the first time. The INPUT and OUTPUT controls vary the capacitors and provide fine adjustments.

NOTES

 

  1. An SWR or 1:1 is best, but an SWR as high as 2:1 may be acceptable. Check you transmitter manual for details.
  2. If you cannot get an acceptable SWR, lengthen or shorten your antenna and/or feedlines and retune.
  3. If you get low SWR readings at more than one setting, use the setting that:

 

Gives the highest FORWARD power reading.

 

Gives the lowest REFLECTED power reading.

 

Uses the largest capacitance (highest number) on the TRANSMITTER and ANTENNA controls.

 

  1. Anytime a new or different antenna is connected, it is necessary to repeat the tuning procedure for each antenna.

DUAL-IN-LINE bhi supplied by LAMCO Barnsley my favourite HAM store in the world 5 Doncaster Road Barnsley S70 1TH

 

BHI Dual In-Line Noise Cancelling Module

Multi-task your audio with this stereo/dual channel noise cancelling unit!

The bhi Dual In-Line DSP noise eliminating module provides mono/stereo noise cancellation, and is suitable for use on all radios and receivers including SDR, especially those with stereo or two channel output options. It can be used with a mono speaker level input signal or a stereo line level input.  There are three output sockets, a 7 Watt mono 3.5mm speaker output, 3.5mm stereo line level output and a 3.5mm stereo headphone socket. Note: The 7 Watt mono amplifier only powers up when a 3.5mm mono plug lead is actually connected to the “Audio Out” socket. If you connect a stereo plug into the “Audio Out” socket there will be no audio!

The bhi Dual In-Line module incorporates the latest bhi dual channel/stereo DSP noise cancelling technology, which has an improved noise cancelling algorithm that brings even better quality audio to the listener when operating in very noisy conditions.  The processed speech is clearer and more intelligible as a result and makes your listening experience so much better.

The module caters for both high and medium level mono and stereo audio input signals, and has stereo line out, stereo headphone and mono speaker output sockets.  You can listen with headphones and a mono speaker at the same time, and you can also connect a pair of stereo computer speakers to the line output socket allowing you to monitor two separate channels at the same time.  This feature is ideal for DXing, club stations, training, special event stations and field day events.

Features

  • New improved dual channel DSP noise cancelling algorithm
  • Improved audio quality – processed speech much clearer and intelligble
  • Use with mono, stereo or two separate channels

  1. BALANCED OUTPUT

Two feedthrough ceramic posts for output to RF balanced twin-lead antennas.

  1. INSTALL JUMPER – when using Balanced Output

 

INSTALLATION

Select a location for the DU 3000 that allows the connectors to be free of any possible contact during operation.

 

WARNING: SOME BALANCED OR END-FED ANTENNAS WILL PRODUCE HIGH RF VOLTAGES AT THE FEEDTHROUGH CONNECTORS. RF BURNS MAY RESULT IF TOUCHED DURING TRANSMISSION.

 

INSTALLATION PROCEDURES

  1. Connect a coax cable from your transmitter or receiver to the RF INPUT connector on the rear panel. Keep the cable as short as possible. If you use a linear amplifier, connect your transmitter to the linear amplifier output to the DU 3000.
  2. Connect coax cable(s) from your antenna to COAX 1 or COAX 2 connectors on the rear panel.These connectors are either direct from the transmitter or trough the tuned circuit depending on the setting of the OUTPUT SELECTOR switch on the front panel.
  3. If you are using a balanced feed antenna, connect the INSTALL JUMPER in the COAX 1 connector and switch band switch TUNED COAX 1.
  4. If using a single wire antenna, connect it to post COAX 1 without installing jumper.
  5. Connect a dummy load to the BYPASS CONNECTOR using a coax cable.

This lets you select the dummy load from the OUTPUT SELECTOR switch. Any antenna that does not require the use or fan antenna tuner may be connected to the BYPASS connector, if desired.

 

BEFORE OPERATION

  1. To avoid possible damage to the DU 3000, set INPUT, OUTPUT, BAND SWITCH and POWER RANGE switches as outlined in the next section before applying transmitter power.(Tuning Section)

 

  1. Begin tuning with your transmitter set to a low power setting (~50 w is more than enough)

 

WARNING: DO NOT OPERATE THE DU 3000 WITH THE COVER

OFF!

 

NOTES

  1. An SWR or 1:1 is best, but an SWR as high as 2:1may be acceptable. Check you transmitter manual for details.

 

  1. If you cannot get an acceptable SWR, lengthen or shorten you antenna and/or feedlines and retune.
  2. If you get low SWR readings at more than one setting,use the setting that:

 

Gives the highest FORWARD power reading.

Gives the lowest REFLECTED power reading.

 

Uses the largest capacitance (highest number) on the TRANSMITTER and ANTENNA controls.

 

  1. Any time a new or different antenna is connected, it is necessary to repeat the tuning procedure for each antenna.

BEFORE OPERATION

 

  1. To avoid possible damage to the DU 1500,set INPUT,OUTPUT,BAND SWITCH

and POWER RANGE switches as outlined int he next section before applyng

transmitter power.(Tuning Section)

  1. Begin tuning with your transmitter se tat a low power setting ( 50 to 100W)

 

WARNING: DO NOT OPERATE THE DU 1500 WITH THE COVER OFF!

 

TUNING

 

  1. Select the band and frequency of desired operation.
  2. Set INPUT,OUTPUT,and BAND SWITCH controls to the suggested settings before

applyng transmitter power.Actual settings may vary from antenna to antenna.

 

  1. Set up your transmitter to a low power output.If you transmitter has a TUNE

position,select that position.

 

  1. If you use a linear amplifier,set itt o STANDBY. Do not use the linear amplifier

until the DU 1500 is tuned.

 

 

WARNING:DO NOT EXCEED 1500WATTS AVERAGE(SINGLE TONE).

 

  1. Set POWER RANGE switch to 200W.

 

  1. Set OUTPUT SELECTOR switch to BYPASS,or the position matching your antenna

connection.To tune your antenna,the switch selection must be set to:COAX 1 TUNED

COAX 2 TUNED,or BAL.LINE+COAX 1.Selecting COAX 1 DIRECT,COAX 2

DIRECT, or BYPASS.

 

  1. Rotate the INPUT and OUTPUT controls for maximum noise or signal as heard

on your receiver.

 

  1. Key your transmitter and adjust the power level for a reading of 50-100 watts on the

FORWARD scale.Adjust the INPUT and OUTPUT controls for

a minimum REFLECTED reading while maintaining a FORWARD reading of 50-

100 watts using your transmitter power control.

 

  1. Read the SWR on the red scale at the point where the two needles intersect.Repeat step

8 until the lowest SWR reading is obtained. The SWR should be 2:1 or lower.

NOTE:This procedure takes patience the first time.The INPUT and OUTPUT

Controls vary the capacitors and provide fine adjustments.

 

 

 

NOTES

An SWR or 1:1 is best,buta n SWR as high as 2:1 may be acceptable. Check

you transmitter manual for details.

 

  1. If you cannot get an acceptable SWR, lengthen or shorten you antenna and/

or feedlines and retune.

 

  1. If you grt low SWR readings at more than one setting,use the setting that:

 

Gives the highest FORWARD power reading.

 

Gives the lowest REFLECTED power reading.

 

Uses the largest capacitance (highest number) ont he TRANSMITTER and

ANTENNA controls.

 

  1. Any time a new or different antenna is connected,it is necessary to repeat the tuning

procedure for each antenna.
