Not to step on any toes here....but, could a person use one of the Softrock SDR radios tuned to the IF of the K3 and have a panoramic view of the band? Anone doing that or am I missing something? That would be cool cause the Softrocks are rather inexpensive. Lee - K0Wa In our day and age it seems that Common Sense is in short supply. If you don't have any Common Sense - get some Common Sense and use it. If you can't find any Common Sense, ask for help from somebody who has some Common Sense. Is Common Sense divine? _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list. Subscriber Info (Addr.

As I understand it, the difficulty is not in feeding the IF into a Softrock, but in preventing the Softrock feeding its local oscillator into the K3 and compromising that's performance.

to mediate the reverse leakage, you can insert a buffer amplifier between K3 and softrock, there's a small kit available just for that called Z10000 by cliftonlaboratories at http://www.cliftonlaboratories.com/z10000_buffer_amp.htm That's what I'm currently putting together - Wim

It may be on the inside but to those of us on the outside it is still a monolithic radio. It is also locked into the processing power that it now has. It is difficult to take advantage of Moore's Law the way it is currently designed. (Moore's Law says that computing power per dollar doubles every 18 months. Anyone buying a PC understands this.) Also, we can't make changes. We are dependent on Lyle and Wayne to have the same interest we do in the features we want and we need them to do the work. This is the disadvantage of a closed environment. I have been on the fence for quite some time and have finally decided to go the route of a Flex 5000 instead of a K3. Even tho' I think that the K3 has a better receiver for traditional modes, I believe that the open software of the Flex and other hardware like the SoftRock will end up offering me more in the long run. Yes I give up some in BDR and IP3 but I get back huge flexibility and expandability with new modulation schemes. I can even hack the code if I want. So it is more appealing to the engineer/hacker in me. But I plan to stick with the K2 as a portable rig. I still really like that little radio. I would love to see Elecraft open up the code for the K2. -- 73 de Brian, WB6RQN Brian Lloyd - brian HYPHEN wb6rqn AT lloyd DOT com _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

In Amateur radio circles these concepts are often confused. The K3 *is* a Software Defined Radio. It is not PC based. It is not open source. Our hardware schematics freely available for download. The SDR from Flex is PC based. It is open source. The schematics are not published. Enjoy!

In 1965 Gordon Moore stated "The number of transistors on a chip will double
about every two years". In 1968 this became known as Moore's law. Typically this is done through shrinking geometries.

That assumes that the DSP portion of the radio is "maxed out" (which is not the case presently) and that one can not (or chooses not) to replace the DSP should Elecraft offer an upgrade to take advantage of newer/better technology. > I have been on the fence for quite some time and have finally > decided to go the route of a Flex 5000 instead of a K3.

That is fine if you have the time, expertise, and programming tools to modify PowerSDR or create your own replacement. Most users do not have that luxury and the performance/usability advantages of the K3 are significant in several key areas. 73, ...

There is actually a problem with this in that, in the near future, scaling will reach a point where the physics breaks down and oxide thicknesses are so small that electrons simply (quantum mechanically) tunnel through them, and the number of electrons in a memory cell capacitor tends to one. Quite a few sources suggest this will be around the end of the decade. Unless some other way of continuing the speed up process can be found, this might have an interesting effect on the rate of software "inventions", as many of these aren't really new ideas, but ones that would have run too slowly at the time they were first thought of. Incidentally, Peter Hart's review volunteers that the K3 is effectively an SDR. (Also for those not familiar with RadCom, Peter Hart does solid technical reviews, however they also have reviewers who are basically journalists (the one who did the handie one used to work for a commercial ham magazine). Increasingly the journalist reviews seem to be infomercials, as the RSGB shop then (acting as an order taking agent) sells the products at a discount.) -- David Woolley Emails are not formal business letters, whatever businesses may want. RFC1855 says there should be an address here, but, in a world of spam, that is no longer good advice, as archive address hiding may not work. _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.
