                • Having Fun With Olivia (HF SWL Ham Radio)

                  As an amateur radio hobbyist, I enjoy communicating with stations from around the world, using radio waves that are reflected off of the Ionosphere. One of the modes of communications we use on shortwave radio spectrum is known as, "Olivia." Olivia MFSK is an amateur radioteletype protocol designed to work in difficult (low signal-to-noise ratio plus multipath propagation) conditions on shortwave bands. The signal can still be properly copied when it is buried 10 dB below the noise floor (i.e. when the amplitude of the noise is just over 3 times that of the signal). It is commonly used by amateur radio operators to reliably transmit ASCII characters over noisy channels using the high frequency (3-30MHz) spectrum. Olivia modes are commonly referred to as Olivia X / Y (or, alternatively, Olivia Y / X ), where X refers to the number of different audio tones transmitted and Y refers to the bandwidth in hertz over which these signals are spread. Examples of common Olivia modes are 16/500, 32/1000 and 8/250. Using computer sound card technology, an amateur radio operator may use this digital mode with just a simple radio-to-computer interface. This mode works well with low to moderate power levels (less than 100 watts of transmit power). Here is a good website about Olivia: http://www.oliviamode.com/ Also: http://en.wikipedia.org/wiki/Olivia_MFSK I hope to meet you, on the air, using this digital mode... 73 de NW7US http://NW7US.us

                    Please do not over-drive your transmitter by setting your soundcard output level too high. And, check for RF getting back into your audio. Bad audio causes transmitted signal spurs and interference on the transmitted signal for which you are responsible. http://NW7US.us/jt65a.html is a reference with a how-to guide on setting up your JT65A digital station. When using any digital mode, for instance in our interest of JT65A operation, it is critical that you do not over-drive your transmitter. Concerning ALC readings and digital operation: In every case that I am familiar with, any ALC action at all indicates that the processing circuits are dropping back the audio drive so the radio will not be over-driven. This results in a non-linear mode of operation, since the output does not follow the input in a straight line. The output drops off or stays the same, regardless of an increase in the audio signal level -- in other words, *not linear* ! Digital modes require that the radio transmit a linear signal at all times. This translates to the fact that there should never be an ALC indication when you are transmitting! Now, on occasional "twitch" of the indicator is OK, but even that will cause the signal to be wide and the error rate for the other station will go up, and there will be splatter during those times of ALC movement. So: keep the audio drive settings below that which causes any ALC indication to show, and your transmissions should be clean and pure. 73 de NW7US http://NW7US.us
