Thanks Lucky That's about the price I would have expected on Ebay. I've seen 'em go for less, but I've seen 'em go for more, too. I know a couple of folks who use highpass filters on their 150's. My understanding is that, if you just suppress everything below 1700khz, then you won't need anything like the Lowe preselector. Others may have some first hand insights to offer here. Also, as for the keypad, 150 owners might consider getting a remote control unit for the Lowe instead. I think this will prove more convenient and probably offer more in the way of functionality. Go to www.swl-remotes.com and take a look. (I have no connection to swl-remotes, other than being a satisfied customer.) Steve I would willing to pay a little more for one if it was in excellent cond and the seller was superb. It's easy to get stuck with a bad radio nowadays. Lucky |

You can run it active with a 9 volt battery too. But, the 150 has a built in preamp. But that's only for the whip right? Still, you can clip a longwire to the antenna. This idea ist not that good for me. I like to feed the preamp with a sinal from the attic 6th floor (my appartment is on base floor) and not with computer noise :-) There are some unused chimneys I run some coax-feedlines through. Unfortunately I'm forbidden to go on top of the roof :-(( |

I've never found a reason here to use an 'outboard' pre-selector. dxAce Michigan USA |

I've never found a reason here to use an 'outboard' pre-selector. For sure I don't need this on the NRD-525 as you dont need one on the Drake-R8B... :-) But as I had the things available I gave it a try on the NRD too :-) On the Sony the external antenna with the FRA/FRT combo works wonders. You can use them together to passbandtune for much more seletivity than the Yaesu FRT-7700 preselector alone is giving. For sure you have to fiddle on the knobs a lot. This may be another thing with other brands. |

This may be another thing with other brands. Well, years ago, when I got back into the shortwave hobby (circa 1982 or so) I did eventually purchase a FRT-7700 for use with the FRG-7700 which I had at the time. |

I've this thing cascaded with the FRT-7700. It works fine with my Sony but it doesn't make anything better on my NRD-525. You can run it active with a 9 volt battery too. But, the 150 has a built in preamp. But that's only for the whip right? Still, you can clip a longwire to the antenna. Lucky I'm pretty sure it's set up like the 7030. The whip connects to the regular antenna jack. You can use the preamp with any antenna, but if it's a large one, you should expect overloading. |

I'm spoiled by the preamps on the R-75. Lucky |
