Comparison
Panasonic RF-B65 Sony ICF-SW7600GR Tecsun PL-660.
All 3 receivers are excellent in their class, but if we compare them, there are some variances. This comparison
concerns my receivers and reflects my preferencies and experience. All of them have power suply 4 AA elements
and current consumption about 70 mA.
On MW and LW band they are less sensitive on ferrite as the best analog devices in their size or slightly bigger.
