Frequency lists (mainly data Pocsag, Baudot, SW, VHF/UHF etc etc) ?
"Steven Fritts" wrote in message ... Amateur RTTY is normally 45 baud at 170 shift NOT 60 baud He said 60 WPM which is 45 baud.

It supposedly decodes POCSAG (pager messaging), AUTOR, GOLAY, SUPOCS, DTMF, DCS, CTCSS, SWED-ARQ, FEC-A, ASCII, BAUDOT, FAX messages. I have only been able to decode ACARS messages (Aircraft) up to now. Mainly due to the fact that i cannot find out any frequencies for the above types of broadcast. I have googled, but just keep getting sites which are either out of date, not there any longer or don't have any detailed info there. The pocsag can be found around 150 to 155 mhz or so. The DTMF is the touchtones on your telephone. Very seldom used on the radio. Hams use it to control some repeaters but it is seldom used. CTCSS is the subaudio tones often found on many vhf 2-way transmitters. Not really much to decode other than the rewquency they are using. You probably have to tap off the 'discriminator' to get them as the start around 88 hz and quit around 250 hz. Thsi low frequency audio will not pass most audio stages in the scanner. Baudot is seldom found outside the ham bands. Look around 14.080 to 14.100 mhz . It will be 60 wpm and 170 hz shift. Set the receiver for LSB and you may have to set the decoder to the Reverse position. I am not familiar with that converter. |
