Morse Reader JEP Electronics Spectrum Morse Reader ------------------- The Programme should be loaded in the normal way, i.e. LOAD "", or if prefered, LOAD "MR1.1". The programme is self starting and the menu page will offer several choices. Pressing enter will select the highlighted option, and the highlight bar is moved by Pressing 6 to move down, or 7 to move up. When in RECEIVE. a tuning aid square will flash at the top right of the screen. Pressing T will turn this function off. The QSO review options are self explanatory. At this Point the cassette Player should be disconnected and the extension speaker socket of the receiver should be connected to the EAR socket of the computer, and a. small audio amplifier may also be connected to the MIKE socket of the Spectrum. This amplifier is not essential, but does enable the signal being heard by the Spectrum to be monitored. Any small audio amplifier is suitable, and should cause no additional expense. Most receiver extension speaker sockets are 3.5mm Jacks allowing the use of the leads supplied with your Spectrum, for these connections. Before connecting the computer to your receiver we would suggest that you check the antenna isolator on your T.V. set. Breakdown of this isolator can result in your comPuter sockets being above earth Potential. In one case we are aware of the Spectrum's sockets were some 85 volts above the earthed case of the receiver. A number of the Power SUPPLY Units issued with the Spectrum have been found to give considerably more than the nine volts D.C. specified. This, of course, causes overheating and shortens the life of the voltage regulator in the Spectrum. In addition, it can result in noise being generated in the voltage regulator which could affect the operation of this Programme. We suggest that you should check the ON LOAD voltage of your Power SuppIy Unit and should it be much above 9 volts, that you either fit an external voltage regulator or that you drop the voltage by means of a suitable series resistance. Some People experience a Problem when using the Programme in an actual QS0 due to interference between the computer and the transceiver. Should the Programme appear to be working O.K. but the Print-out on the screen be meaningless remember that you may be copying a. station working in a language which is unfamiliar to you.. Also, of course, the abreviations used by radio amateurs may not be familiar to You. To help in this respect we enclose a list of the more common ones in use. Since the Programme Prints on the screen the character it hears, it makes an excellent aid to your sending Practice. Connect the EAR socket. of the computer to your practice oscillator, or so that it may hear the side tone from your transmitter. (We hope the result doesn't give you too big a shock!) Should you wish to clear the screen while morse is being received, Press key O. (not zero.) This routine will only work if morse is actually being decoded while the key is Pressed. The Programme is recorded twice, about ten seconds apart, so that you have a back-up copy in the event of an accident. The receiver should now be tuned to a medium speed morse signal of reasonable strength and with the computer in the READY mode the RF and AUDIO gain controls of your receiver can be adjusted for best balance between background noise and signal levels. Having the receiver volume set too high or too low will result in the screen remaining blank. Too high a level of background noise will usually cause the computer to Print strings of E's and I's. While the Programme is self tracking at speeds between about 8 and 30 WPM, a sudden change from a very fast to a very slow speed will sometimes cause the computer to lock, causing it to Print rows of T's and M's. Pressing the reset key R while a couple of morse characters are received will normally free the condition, allowing normal tracking to resume. While the Programme will cope with a certain amount of bid sending at slow speeds, it is not so tolerant at high speeds. It cannot cope with really bad sending: in particular with the operator who fails to insert spaces between characters. We recomend that the transceiver be earthed to an outside earth spike, while the T.V. set be earthed to the mains earth. Often the interference is radiated from the lead between the computer and the T.V. set and in this case a high pass filter is often the answer. Finally, may we respectfully remind you that this programme is sold on the understanding that it should not be copied, lent or hired without our Prior Permission in writing. J. F.
