While AH6TD is fundamentally an Apple Macintosh station, I have been interested in an absolutely incredible piece of software, free software, called Ham Radio Deluxe. For the longest time, however, I have been unable to use the latest version, version 5, because it was astoundingly unstable. No more. Ham Radio Deluxe 5 is alive and well at AH6TD. . . . To read the rest of this article, please click here: → Ham Radio Deluxe 5 Alive and Well at AH6TD While in theory a ham could be using PSK31 as their mode of transmission anywhere that “RTTY and DATA” are permitted, there are specific frequencies where PSK31 tends to be used. Here’s a list as I’ve been able to compile it: 160 Meters 1.838 MHz 80 Meters 3.580 MHz 40 Meters 7.070 MHz 30 Meters 10.140 MHz 20 Meters 14.070 MHz 17 Meters 18.100 MHz 15 Meters 21.070 MHz 12 Meters 24.920 MHz 10 Meters 28.120 MHz 6 Meters 50.290 MHz It’s been my experience as of this writing that all one has to do is tune to whichever of these frequencies that has PSK31 activity on it, . . . To read the rest of this article, please click here: → PSK31 Calling Frequencies A properly adjusted PSK31 signal is only 31Hz wide. Yes, you read that right…31Hz. (As a comparison, the typical SSB voice transmission is 3000 Hz or 3KHz wide). However, PSK31 is prone to splatter when the rig is overdriven with audio. It’s important to adjust the audio levels such that the rig isn’t over driven so that no splatter is created and you stay within the 31 Hz. width you’re supposed to. It seems that everywhere you go, people provide procedures for adjusting your transmit audio levels as a function of the ALC meter on your rig. There is, of course, nothing wrong with this…it’s a perfectly acceptable and . . . To read the rest of this article, please click here: → Adjust PSK31 Audio Levels Without ALC |
