Insert HTML tags _ «Previous Next» Digital Image TRX software KG-STV ver.1.0.0 readme -------------------------------------------------- -------------------- KG-STV the time to download and use, thank you. This KG-STV is a digital image using a software radio transceiver. Since this software to decode digital signal processing, external There is no need to connect the decoder to spin the radio and PC sound input and output Marker microphone jack, and can send and receive PTT RS232C control is connected to. KG-STV will process each image block in order to send you additional information about individual Overall picture is just black but only part missing in the middle of this data is received And is available.Images from the middle to play the middle of the signal it receives and Possible. About a block is not received, retransmission request (BSR) to make up for it You can. 320x240pixcel image around 2 minutes (depending on compression settings, image) can be transmitted by Eh The FSK modem is a type of MSK (Minimum Shift Keying) or by using 4LFSK, PSK and OFDM in to use the full power of the amplifier compared to the final stage of the modulated radio system Come, we hope to extend the transmission distance. Install Uninstall ○ Extract the compressed file will install the downloaded file after extracting You only need to copy the folder to anywhere and just. Thawing process, Windows unzip program if contains the standard file compression Double-click to open Le files to another folder in the folder that appears By extracting the copy is complete.When extracting the folders listed on archive Temporary condition, so that only displays the contents of the file, copy it to another folder must Please complete the decompression. Right-click the compressed file also on the menu "Extract All" item of If so, you can click it to unpack it. If there is no standard unzip program to unzip the line extraction software separately And.The extraction software may not be able to decompress is well.Recommendation Lhaplus1.56 is that the decompression software. Please change the name from the initial state of the folder structure and still.The startup You can become unavailable and some of the functionality and Kinakatsu. We do not use the uninstall any registry, folders, Please delete as it is. ○ equipment needed to receive To receive the following equipment is required. 1.SSB or FM radio which is equipped with mode 2.Consistent with the antenna off the radio antenna 3.Specifications which meet the following computer 4.PC software used for data communications cable general cable radio ○ Radio KG-STV SSB and FM are the possible transmission of image data in.Other Mode (AM) may become unstable in the transmission. May deteriorate receiver performance characteristics and transmitted by radio.In that case KG-STV degree of degradation is observed in the eye pattern. ○ antenna The antenna is required adjustments can be sent. ○ PC KG-STV to work the computer must have at least the following specifications. OS: WindowsVista / XP CPU: Celeron 1GHz or more Memory: 1GByte more Display: 1024x768pxcel more Sound: 48kHz 16bit support ○ PC connection cable, radio Connect the radio speaker microphone jack and the computer not only receives Just OK, but if you do this and also send out another line of PCs Attenuator with cable and connect the power and radio microphone, PTT control path for The RS232C PCs and radios PTT circuit is required to connect the terminal. These are the same wiring and communications software and a PC with a general picture It is possible to reuse these cables. The KG-STV signal using the VOX PTT can also be controlled. ○ KG-STV setup KG-STV install, complete with wireless connectivity can be used for KG-STV Set and adjust. The sound input and output device selection first.To do this the KG-STV Set the selection screen, click Open, Input Device and Output Device Sets Eh RS232C RS232C Port at the same time where we can set the port. After the configuration settings to reflect the OK button. Adjust the modulation level to actually send the waves When you're done. Actually send the following steps both sending sound signals to monitor different receiver Enough to distort the attenuator and cable slide KG-STV, the case Adjust the Windows volume. Speaker outputs the input signal received on a PC as well, enough to distort the sound Cable or radio volume attenuator, possibly adjust the volume of Windows The adjustment. How to operate ○ KG-STV - Receive Just listen for incoming signals troublesome adjustment is not necessary, other You can receive a large gap that the local station and the station frequency.In this case, Aipa Turn to see if there is a lower frequency signal on when and under-frequency Up the number (or reverse operation) received around the middle, so that the radio wave Please adjust the frequency. - Send To send the following steps of image. 1.KG-STV image files drag and drop Jpeg and bmp image files or.The image size is automatically resized It will be 320x240pixcel.With different aspect ratio, and an extra vertical Left and right images are cropped. 2.Coordination and quality check of transmission time Drag and Drop, KG-STV file name and the title of TxTime = Displays.The estimated time required to transmit TxTime.Have a look at this time Send Image quality adjusting them from the top of the second pull-down menu to the right of The decision to send a different image quality. 3.Send Once these operations to send pictures Send Image button. Masu. Send Image in the picture transmission can be interrupted transmission button You can too. · BSR (retransmission request) how If you have not received the received image block, Send BSR Open button operation Accessible.Click here to Send BSR, not be able to receive the other station Send requests retransmission or cell number. - How to re-request response If the retransmission request is received, Resp BSR button so you can operate, Resp BSR resend the image block data is missing, click the partner station. ※ Send BSR and BSR Resp and receive the new image, an image file input on KG-STV If you reset. If you interrupt the request and BSR and BSR BSR while sending response information will be discarded. 4LFSK ○ MSK and transmission of MSK modulation method and digital signal is a kind of method FSK, FSK Mark Frequency Traditional minimize the frequency of the space between the number (Minimum Shift Keying) 4LFSK is that of the 4 FSK, FSK modulation frequency of 04 points set this kind of possible The MSK and you can get twice the transmission speed. MSK in 4LFSK so susceptible to noise while narrower than the frequency, Are susceptible to deterioration and transmission line characteristics. The choice of these two, FM and line status when it is faster to send the image, Good quality image to send 4LFSK I also wish to select.Radio times Precarious state of HF SSB transmission line in MSK data as well to I think that. ○ convolutional code transmission mode Send Image from the pull-down menu above the first pull-down menu to the right of New treatment is a choice of codes.Where no sign processing (NORM) or convolutional code processing (CONV) or to set. The stronger the signal noise and convolutional code processing, the same data transmission It takes about twice as Ru. Check the status code while processing the transmission case by case basis Please choose. Note that this setting can be changed even during transmission. Send and receive text messages ○ KG-STV-byte characters up to 510 in one transmission (255 characters max) Tekisutometsu of You can send a message. To send a text message Resp BSR text entry box at the bottom of Enter, right click SendText. When you receive a text message, text is displayed in the box below.

Out of practical experience and competence of the principal causes, however. Thus the transmission time is slow, poor quality and hard 受Karanai, real luck On for many practical situations, and I think not. In such a case study because we want new challenges, means With the views of many people, including'd appreciate feedback. All means, thank you.
