With the onset of automatic ATUs, is the the final technical
skill that disambiguates the radio amateur from the CBer being lost? |

No! There is still Morse Code using a key! I consider it
a technical skill. Irv VE6BP "gareth" wrote in message ... With the onset of automatic ATUs, is the the final technical skill that disambiguates the radio amateur from the CBer being lost? |

Well. I did make my own mechanical bug key a couple of years ago.

... Far be it from me to suggest that the manual ATU is best suited to those with ape like arms and brains who can reach more distant feed points. Why must you always introduce an element of childish and venomous abuse? |

... Each to his own in the balance between operating vs building etc., after all it seems some who support the latter over the former never finish projects. Another post ... another snide comment |

I'll assume that's a serious question, not another CB versus ham flame bait. What problem are you trying to solve? The legal CB band is roughly 400 KHz wide. There's no need for an automatic antenna tuna to match an antenna with such a narrow operating frequency range. The matching is either built into the antenna, preset in an external box, or just ignored by tolerating the mismatch. Tune or match it once, and forget it. However, HF ham radio uses frequencies with many octaves of frequency range. Building a single 50 ohm antenna to cover all that is rather difficult. Therefore, one uses an antenna tuner (automatic or manual). However, you are correct that the ATU is a dying art. I've been zapped by the high voltages produced by antenna tuners often enough to suspect that dying might be involved in the tuning process. If it's not science, it must be art. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

If it's not science, it must be art. Art - most definitely. But where's the "technical skill" in adjusting a pi network of two capacitors and one inductor? CBers may not need to worry about ATUs, but many are quite capable of using the pi networks on the PAs of their valved rigs which have been re-crystalled for 6.5 and/or 27 MHz. |

If memory serves, the legendary FT101 even included 27MHz coverage. It was certainly reported to be used by more CBers than licensed amateurs. As you suggest, CBers may have been able to compensate for the antenna impedance over their limited bandwidth by using the Pi network. Which demonstrates that some amateurs are put in the shade in technical skill by CBers. |

I'll assume that's a serious question, not another CB versus ham flame bait. What problem are you trying to solve? It is not a question of baiting, but of a serious concern, that amateur radio / ham radio is a technical pursuit and is slowly frittering away such that many radio amateurs are indistinguishable from CBers. From an interest in my teenage years, it was that technical momentum that led me to a career in electronics and subsequently software engineering. Amateur radio has technical privileges that may be legislated out of existence should the various misgovernments of the world perceive that there is no need for us to able to create our own gear when so much is available off-the-shelf, and it is off-the-shelf operating that is the mark of the CBer. |
