On Shortwave (HF) this is a "dual conversion" receiver. The first 10.7MHz IF amp and two 10.7MHz ceramic filters are used on VHF-FM and also HF. The second 10.7MHz IF amp is a mixer (presumably fed by fixed 10.24MHz approx) on SW down to the 455KHz IF. On MW (BC) it appears to be single conversion. It's a pity for Europe, Parts of former USSR and North Africa that it has no LW. I've noticed that most of the Asian portable AM/FM sets even so called "world receivers" on the market recently (2010 to 2012) don't have LW any more. Was there a more European version of this set with LW? |
