Didn't the R390 have a 500KHz IF? Michael |

Instead of playing the 'game' of posting a reply to anything I post.
Your ego is showing. Uh oh -- worlds are colliding. Remember, rec.radio.shortwave is not a radio newsgroup, the people there are not knowledgeable about, or interested in, the technical aspects of radio. If it doesn't involve nasty name-calling or wild-eyed, mouth-foaming political looniness, then it doesn't belong in rec.radio.shortwave. |

Richard: 455000 cps ;-)
LOL Also: 0.455 Mc. Michael: Didn't the R390 have a 500KHz IF? That sounds familiar. Could that have been one of the differences between the 390 and the 390A? 73, Bill, K5BY |

Collins built similar rigs such as
the 75, 51 and R388 (and maybe R389) series only some of which used a 500KHz IF in a fantastic variety of double, triple, and quadruple conversion versions. Thanks,Richard. 73, Bill, K5BY |

"Jeff" wrote in message ... Hi, Does anyone remember a weird compact antenna that was featured in a 60's (or early 70's) edition of "73" magazine. Had 2 etched PCBs (like spaced plates) mounted inside a plastic bucket, and fed with coax? Does anyone know more details of this? JEFF ZL3TNV Wouldn't be a patch antenna by any chance? |
