"Airy R. Bean" wrote in message ... I wonder if we as a NG might put together a design for an HF rig that could be built with ease by novices and experienced constructors alike? I suggest that none of the CB-style gadgets of today's CB-style rigs are necessary and that a reproducible design having only the facilities of, say, the KW2000, would provide the basis of any station. Keeping it simple will increase the chance of success. I suggest the following.... DDS VFO VFO display based upon graphic LCD to simulate the use of a tuning knob-plus-dial. Tuning knob plus flywheel using optical sensors, giving the "Feel" associated with traditional rigs. DSP for the audio and mixing stages, perhaps with a low IF of ooo 50kHz to resolve the ringing problems that arise in narrow baseband filters for CW. ooo 100mW output allowing the choice of PA for CBers-Masquerading-As-Radio-Hams or running barefoot QRP for _REAL_ Radio Hams. Any of the established CB types in this NG are welcome to join this discussion, I only ask that your contributions be meaningful and not the inane sneering 'n; jeering for which you are famous. Bring back the G2DAF rx/tx I say. johnny g3liv. |

IMHO... QRP, for the new-to-HF ham whose Morse (and/or voice procedures) isn't all that solid yet... and who's probably using a comprimise antenna... is really not a good idea. Save it for when one's got some experience under the belt & is interested in trying something new. The homebrew design that would, IMHO, bring a lot of new folks to the HB fold, would be... A simple, inexpensive, easy to duplicate, linear amplifier. 2-5 watts in, 50-100 watts out; good for all HF bands; run from 12V. (yes, there are certain advantages to using 28V, but 12V power supplies are cheap and ubiquitous. I know I misspelled that!) It could be used with a wide variety of existing HB QRP transceivers, or with a variety of commercial QRP gear. -- Doug Smith W9WI Pleasant View (Nashville), TN EM66 http://www.w9wi.com |

That is, the more tests you pass the less power you are allowed. Nobody would upgrade, would they? |

If you start out with a defeatist attitude, and pass that
defeatism onto your protégés, then, yes, you and they will be defeated. "Doug Smith W9WI" wrote in message ... Airy R.
