Its a matter of design but yes at least a double conversion type circuit is the norm or starting point of serious modern superhet design. The Icom R-71s are quadruple conversion and were/are a favorite for utility dxers like myself. Sometimes three or four IFs are problematic with intermod I've heard but I've never had any bad experiences. B.H. |

As you just stated, you have no idea what you are talking about so why are you trying to give advice? mike |

Double conversion, triple conversion, quadruple conversion, sets that
sell for $50.00, sets that sell for 10,000.00! Antennas 3 inches long, 100 feet long, 3 inches high, or 3 miles high! For a beginner, none of it really matters. What DOES matter? EXPERIENCE. That is all. There is no substitute for time and experience and there is no "short-cut," either. And that applies to ANYTHING worth doing! If a beginner is truly interested in the hobby, he or she should just do a little research, perhaps on this group, or, better, in PASSPORT and WRTH, and make a reasonable choice in radios and antennas. It isn't too hard. Most of them out there are pretty good. I, as does everyone else here, have my opinions, but, in the end, for a beginner, it just doesn't matter, within reason. Then, as he/she becomes EXPERIENCED with the radio they have, REGARDLESS of what it is, and with short wave listening in general, why any future equipment "upgrades" will take care of themselves. Just my thoughts. Best, Joe |

Yeah, but my feelings are that buying an elcheapo portable, or even a fairly decent one, is a mistake. They don't work very well, don't hold up all that great for the most part, and lose their value pretty rapidly. There are tons of arrox. $300 used R71A's, Kenwood R5000's and others that are good enough to keep for a while, and can be sold for basically what you pay for them anytime. I have a R71A that I bought for a really cheap price. It had a problem in the PS section that seemed to confound several techs at a couple of places that tried to fix it. It was a very easy fix (an hour total time) and I will get 2-3 times what I paid when I sell it one of these days..if I do sell it.. A friend wanted to try SW a while back, and he bought a very nice NRD- 525 off Ebay for about 400 bucks. After a year or so, he wanted out, and made 20 bucks profit when he put it on Ebay. Get paid to listen, not a bad deal.. BDK Yeah, I tried to tell that to Judah. He must have spent somewhere between $500 and $1000 on cheap doorstop-radios. Think what perusal of a hamfest or two would have done with well-spent $200. Not to mention to the wealth of knowledge he'd pick up there. -- Eric F.
