wrote in message oups.com... This is interesting. Have you (or anyone else in the group) actually used a preselector and/or highpass filter with a 7030 and found it to result in improved performance? The 7030 is said to have such a robust front end that additional filtering is the last thing I'd expect to make a noticeable difference. In fact, I'd expect whatever tiny improvement that resulted from the extra filter to be outweighed by insertion loss. However, I have an open mind about this--as well as a Kiwa highpass filter, standing by. Steve Hi there Steve I'm also interested in that Kiwa highpass filter you mentioned. They do the mod for you too. What have you added to the 150 as improvements? Lucky |

I haven't really added anything. I already had the Kiwa highpass filter
(which is a very good filter) and have been using it to reinforce the 150's front end. The Kiwa filter completely eliminated what minor problems I had with intermodulation. Otherwise the 150 works fine as it is. Steve |

Steve Steve, This is what Kiwa offers for the 150: http://www.kiwa.com/HF150.html Where did you get your highpass filter and did you install it yourself or is it external? Lucky |

Yes, I have the external highpass filter sold by Kiwa. You can find
information about it he http://www.kiwa.com/bcb.html. Since MW DX-ing doesn't interest me very much, and since it's a pain to be tuning a preselector all the time, it's nice to have a filter like this that will heavily attenuate *everything* below 2500 khz. I.C.E. sells a comparable highpass filter (model 402), and I believe Par Electronics does as well. Steve |
