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. |

It would be invaluable info for those interested in furthering their knowlege of the hobby and maybe the end product could equal or exceed the Elecraft specs at a lower price? p. -- The BBC: Licensed at public expense to spread lies. |

I have no experience of the Elecraft kits, but I suspect
that the packing density of components on their PCB's would mediate against future maintenance and fault-finding? Also, for Britland, AIUI, there are problems for the man-in-the-street having to organise his own shipping and passage through customs? A kit of our own design would not be subject to proprietary trade secrets. If the AF amp was specced at, say, 1mw into 600 Ohms, then almost any AF amp chip would do the job. While on the subject of fault -finding, one RX which sticks in my mind as being very easy to repair was the R210, because all the aluminium chassis (pl?) folded out on hinges for easy access. As part of being a _REAL_ Radio Ham is maintaining our own gear, then there is food for thought in this area. "Paul Burridge" wrote in message ...

So you agree that there are problems?
