Why so cheap???? Lucky The previous seller apparently didn't bother to check what they normally close for, and put it up with a low "Buy it now". On the difference between the Europa and the regular HF-150, I'd take the Europa. The input filtering is likely to be more useful than any loss in sensitivity. |

Mark, it says in this comparison between the 150 and the 150E, though there was less images on the 150E, increased noise appeared on those frequencies. The 150E is surely less sensitive too. What do you think now? http://www.anarc.org/naswa/issues/0798/equip0798.html Lucky |

On the difference between the Europa and the regular HF-150, I'd take the Europa. The input filtering is likely to be more useful than any loss in sensitivity. He says: "Incorporating these RF bandpass filters should theoretically reduce spurious responses and noise. I compared the '150E to my early model '150. When the original '150 was connected to my 90/60 meter parallel dipole, there were several frequencies below 3 MHz which had images of local broadcasters. With the '150E , there were no audible images present, but there was increased noise on the same frequencies". and "I found that the original HF-150 was about 0.5 microvolts more sensitive across the HF spectrum, however, the HF-150E was within specification of less than two microvolts throughout the HF spectrum, and was typically in the range of one microvolt. I think that the higher sensitivity of the original may not be a virtue, given the radio's susceptibility for overloading. I don't think that this difference is significant, and switching in the pre-amp on the HF-150E improved the sensitivity to the level of the '150 without pre-amp" So basically he had to switch on the pre amp to bring it up to the 150's sensitivity. If you don't live in areas with strong stations, I'd rather have the sensitivity. Plus, I didn't know the backlight option can't be turned off in the E. So, it will drain your batteries if you ever use it as a portable. Lucky |

Lucky I'd be interested in hearing more about the "increased noise" in the Europa - the reviewer didn't say anything other than he noticed it. Who knows if it's significant? I bring plenty of power for recharging battery packs when I'm camping. I'd gladly trade the convenience of a backlight for a little battery drain. Unless you've taken heroic measures or live in the woods, odds are the noise floor for your antenna will be higher than 2 microvolts. My primary home antenna is 225 feet away from the house, with underground coax, and according to my Harris, the noise floor is right around the limit of the Europa. If you were using the radio to chase DX in the woods, you could use an outboard preamp or an active antenna. When I was looking for a HF-150e or a 7030+ my primary concern was finding a good radio for use when camping, and for when I'm hanging out by the pool or fishing for snook on the other side of Alligator Alley. The HF-150e had the edge on size and would probably have cost less, the 7030+ had the edge on performance, and availability. Both radios were designed by the same person. |

Yes who knows how significant the noise was but if he noticed it, it must of stood out enough. Still, you can't really be sure it can be reproduced on all the E models unless you had at least 3 to test it on at the very same time. But as they said it was produced mainly for the Euro market where conditions are different then where we live. With that gothic gold "Europa" label across the radio it kinda reminds of me of a mini Dracula's coffin Mark you don't mean Alligator Alley in Florida do you? Nah they got alligators in alley's in most states nowadays... Lucky |
