Is this mainly a program listening rig?
How is the SSB on it with no PBT or shift? I guess you can't even compare it to a Drake R8 huh?? Any opinions? Thanks Lucky |

Those are both bells and whistles, very uncommon even thirty years ago, and only slowly moving into more common appearance, and towards lower priced equipment. Good SSB means good stability, good selectivity (sufficiently narrow, and sharp skirts) and a product detector. If it's got that, then it's good for SSB. The other things may help under some conditions, but people have lived without them. Micahel I guess you can't even compare it to a Drake R8 huh?? Any opinions? Thanks Lucky |

These controls are for moving the filter response across the passband, and have no effect on fidelity other than perhaps hurting it off moved too far. The difference between the R8 and the Lowe is that the Lowe is built tremendously better and the Sync modes work as well if not better. Dale W4OP |

There are many SSB stations I would have to listen to with loads of interference if I didn't have them. Some I wouldn't be able to continue listening to at all. Lucky |

Lucky Good question, given that the vast majority of my listening is on SSB, including some SWBC stations with QRM on one sideband - BBC on 12095 for example - what do PBT and IF Shift have to do with SSB performance? If they were important surely they would be standard items in professional receivers? I agree that they can be useful on occasion for getting rid of some QRM, but they are hardly a requirement for good SSB performance. I have, among others, the HF-150, R-5000, Plessey PR155, Eddystone EC-958: none have PBT and only the R-5000 has shift which is very seldom needed, the filters do most of the work. My HAM rigs have both and also are seldom required. Regards Dave |

Lucky I would be tempted to think that there is something seriously wrong if you have to use PBT and shift to be able to listen to SSB stations. Either your receiver or local noise environment need to be looked at. The only other option I see is that you are operating your receiver incorrectly. I have an "older" acquaintance who has a similar problem but insists on listening to SSB with a 16kHz filter - he needs all the help he can get since he refuses to use the correct filter(s). Dave |

Lucky They're just the features you've learned to use to compensate for problems you've faced. On my 7030+ I've installed exceptionally good filters with very steep skirts, so I rarely need to tweak the PBT to eliminate interference. But the real reason I added those filters was the ones that came with the radio were too wide or too narrow for me. The fact better filters simplified using the radio was just a bonus. On the Harris, I just use the sync detector and coherent AGC and it sounds beautiful. The HF-150 is one of those radios hardly anyone complains about - I never bought one, but I spent a while looking for the Europa version before I ended up with my 7030+. I wanted as much performance as I could get in the smallest possible package, and it had to be reasonably practical to run on rechargeable batteries. I'm very happy with the decision I made, but if I'd found a HF-150 Europa first, I probably would have gone for it. (and then I'd probably have tried the 7030 anyway) |
