Using The Control Center With The Ambe Option Board

Transcript

Using the Control Center with the AMBE option board Rev.: 1.0 / DJ0ABR When the AMBE board is installed, a new Tab will appear „DV-TRX“. Here you can set parameters like in most normal DV transceivers. Here are the setting in detail: URCALL: should be set to CQCQCQ for normal operation. May be set to individual callsigns if you want to use callsign routing RPT1 and RPT2: Set it to the callsign of your most used repeater. This setting is corrected automatically in case you use another repeater. Therefore it is not necessary to change this setting. Don't forget the modul letter (A,B or C) at the 8th character for RPT1 and the letter 'G' at the 8th character for RPT2. If the length of the entry is not 8 then the text is displayed in red color. MYCALL: Your personal callsign SUFFIX: 4 characters which are sent together with your callsign. I.e. Your name, city, transceiver or any other information TX-Msg1 and TX-Msg2: This message (length 20 characters) will be automatically sent during your transmission. The radio button on the right selects which message to send. RX-Msg and GPS-RX-msg: Displays the last received message from your QSO partner Voice Settings: Speaker volume for received voice. Microphone – Volume: Sets the microphone pre-amplifier. Please use it with care, don't set it too load or your voice may be clipped. Filter: There are 5 different filters available for the microphone. This allows you to adapt the microphone amplifier to various microphones. low … this is a low pass filter attenuating the higher frequencies. normal … a flat filter curve high-1 … high pass filter with 300 Hz edge frequency high-2 … high pass filter with 400 Hz edge frequency high-3 … high pass filter with 500 Hz edge frequency In addition to these filters you can set the filter level 1 to 5. Where 1 is a soft filter and 5 is the most agressive filter setting. The filter level has no meaning for the „normal“ flat filter. Usual settings are normal or high-1 at Level 2. Attention: Setting the filter is ONLY possible in receive mode. When you press PTT then the settings will be disabled. When releasing the PTT then the settings will be enabled after 7 seconds. Therefore it is not possible to change the filter while talking. Type: dynamic or electret: set it to the type of your microphone. When set to electret than a DC voltage of about 3 volts will be applied to the microphone line. Button: Store Settings into DV-RPTR EEPROM“ pushing this button downloads all settings in this window into the DV-RPTR boards EEPROM. Now you can use the DV-RPTR without PC (USB disconnected). First of all make the settings as described here and test it during a QSO, still using a PC and the Control Center. If all works well, press the red button. This stores the settings into the EEPROM of the DV-RPTR. Disconnect the power supply and the USB cable. Reconnect the power supply (no USB cable) and the board works without a PC now. Remark: In firmware 1.63c the filter settings are not stored in EEPROM, according to the firmware programmer Jan, DO1FJN, this will come in the next version. Other Settings required for AMBE operation: Using the AMBE board you have 2 options: 1. DV Transceiver mode 2. DV Dongle mode DV Transceiver mode: use this setting if you have an FM-transceiver connected to your DV-RPTR board. Now you have a real DV transceiver and you can make your QSOs on your local DV-Repeaters or direct. DV Dongle mode: use this setting if you do not have a transceiver. This allows you to talk directly to reflectors through your internet connection. Hardware Information: There is a connector for the microphone and one for the speaker. Speaker/Mics from Kenwood fit into these connectors. We use the Kenwood Team JD-3602 which is sold for about 20 Eur. There are a couple of Speaker/Mics in ebay which are compatible with Kenwood and very cheap. It is also possible to connect other mics and speakers using adapter cables. It is important that the PTT line is separate from the mic line. This is the case with Kenwood Speaker/Mics. Ground Problems: Kenwood Speaker Mics have only one ground line, which is one of the speaker lines. The microphone uses this ground line too. Therefore it is very important that this ground line is correctly connected. If your modulation has a very load noise, then the ground line is not correctly connected within the microphone. In this case open the microphone and swap the two speaker lines. This should solve the noise problem. Firmware Information: To use the AMBE addon board you must have Firmware 1.63c or later installed. This firmware is included in the Control Center ZIP file. A manual describing flashing your board can be found in the DVRPTR yahoo group.
