You will find the tuner in particular will raise the signal level, but it will raise everything and no new signals will magically appear from the ether. I've got two hi-fi tuners that overload on the outdoor long-wire (on AM, of course). Is there a way to tune, preselect, detune, balun, resist, or whatever the antenna so I can use it? The simplest solution is to reduce the signal strength. cut back on the gain control or switch in the attenuator if your radio has one. |

Of course, it comes with no whip antenna. Runs off of a 9V battery as well as from a wall wart (just like the 1020C). The description says the 1045C accomodates 2 antennae and 2 receivers: not true; it's for one antenna and one receiver, although it does have both a UHF and an RCA connector for your antenna connection and the same for connection to your receiver. junius Although I will google this, I'll continue the thread by asking; What's the difference between a tuner and a preslector?

Eventually I'll set up an outdoor dipole or something similar. Unless you are experiencing problems I would not look for a solution. An R1000 will do just fine on a simple longwire. believe the radio has an attenuator and an rf gain, and both can be used to minimize strong signal effects. Congrats on owning a classic. |

It's a really nice radio. Got it off eBay a while ago. First non-portable I've had in many many years. Should have done it long ago. Blows the portables away. |

If you're tuning an unbalanced, random-length wire, the MFJ 16010 L-circuit tuner is fine, and is only 49.95 For a balanced antenna, a dipole, say, the MFJ 901B Versa Tuner would work -- it's 79.99 The MFJ 956 preselector/tuner is another possibility bob k5qwg |

You need a tapped air core coil, a variable cap, a few clip leads and a slab of peg-board. Excellent first project. |

HiFi AM tuners suck. Compared to what? Real radios. They usually just throw in a single IC chip tuner that brick-walls the high frequncies at around 4500 Hertz. If you try to use anything other than the 6 feet of wire on a loop that comes with the receiver the things will overload like crazy. |

Radio Shack sells Type F attenuators. |

MFJ are not well known for their quality control. They have good stuff but their QC sucks out loud. It's a well know fact among hams everywhere. They are very nice on the phone. One good thing about them is they encourage you to take their stuff apart. Hams are full of it. |
