this volume issue is annoying. i actually like listening to CRI - it can be interesting at times. The only chance I have is in the car
SONY makes shortwave/LW car stereos, and there are numerous highpower CRI transmissions from Sackville Canada which boom in on 49 and 31 meters. you can also get european broadcasters near the coast easily. BBCWS on 198 (often with less fading than SW) ,a variety of french, german and Moroccan/Algerian stations, Iceland...
besides WILD and SW theres drive-time CRI on 950 WROL
