I have a Drake SW-4A that I would like to use to listen to AM English broadcasts. In playing with it, it seems that some of the bands that came with it are about useless here in Arizona for what I want. I am interested in changing out some of the crystals to get bands that are more useful for me. Which of these bands should I change and to what? These are what I have that I have. 5.950 - 6.550 MHz 6.950 - 7.550 MHz 9.450 - 10.050 MHz 11.450 - 12.050 MHz 14.950 - 15.450 MHz 17.450 - 18.050 MHz 21.450 - 22.050 MHz 25.450 - 26.050 MHz.
Thanks, Al, n7ioh
Those are most of the shortwave broadcast bands (49, 41, 31, 25, 19, 16, 13, and 11 meters, respectively). There aren't many English-language broadcasters left compared to 20+ years ago, but there still are some. Australia and New Zealand are still easily heard in our part of the world. So are China and (if you want a good laugh) North Korea.
I would change the following:
49 meters: 5750-6350
41 meters: 7150-7750
I would add the following if you have room:
60 meters: 4750-5350
22 meters: 13550-14150
11 meters is expendable with decreasing sunspots, unless you want to monitor CB. If that's the case, change it to 26950-27550.
If you're not hearing anything, check your antenna unless the radio went south. I'm also in Arizona and can hear at least something on an indoor antenna in Mesa. Outdoor, of course, is better, HOA willing.
