Here, loops are a primary antenna type - unless you have very understanding neighbors.Many thanks to SWLing Post contributor, Ray Novak, who notes that Icom has issued the following firmware updates for the IC-7300 and IC-9700: Icom IC-7300 Update Hams have a couple of secondary allocations there, so in certain areas, you will hear digital modes that can be copied with the right software, and of course, NAVTEX can be heard primarily on 518 Khz, altho there are other frequencies less used as well. Some front end filtering will be necessary in such cases if you want to browse in that band. So if you hear US broadcasters on LW, it's likely to be a mixing product from strong MW stations. In fact, I don't think the ITU has allocated that band for broadcasting in the Americas. I got booted off a Facebook group for saying this (heh) - there is no US broadcasting in the 155-281 khz range, so engineers see no reason to put together a good front end for that range. The email reflectors for the various radios are a great resource for finding out about these, and how to remove the attenuation Sometimes the MW attenuation is nothing more than a pot or a resistor strapped and grounded. That you can get when chasing LW beacons for example. If MW and LW is part of your plans, then get a radio that is not desensitized down there. However, it maybe an indication that the MW and LW coverage is not considered that important on what is primarilyĪ HAM radio. This is done to prevent overloading by strong local AM BCB Is intentionally reduced, sometimes drastically, below 160 meters. One other thing about sensitivity, if you are into AM broadcast band or longwave listening, be aware that some receivers sensitivity The ARRL lab product reviews found in QST give This is what separates the good radios from the really good radios. Take a real close look at the dynamic range specs as prcguy mentioned. When comparing receivers, you will probably find that the sensitivity specs all seem to be pretty good but If you want a new desktop SWL receiver nowadays, a HAM transceiver with general coverage receive capability is about
