K2 NB
Locked
 
|
A comment about the K2NB and the different reasons that we perceive as being
responsible for the lack of its improvement: Just how much would an optimized NB design cost as to become prohibitive for the average Elecraft customer ??? We already have a DSP option costing >$300 which many people think as very important and continue buying. An optimized NB is guarantied to be both more important and more desirable feature, which I doubt it very much can approach the above cost. (even if it did I, and many other fellow Elecrafters would still go for it) On the other hand, having such an expensive NB available does not necessarily mean that the current design would have to be discontinued. I am sure there are also many of us absolutely satisfied and delighted by the current NB, and some lucky hams do not even get pulse noise ever at their QTH's. These customers could still have the option of getting this K2NB at its low cost and complexity, but for heaven's sake, give the rest of us urban dwellers the chance to optimize our K2s.

Interesting comments Marinos,
Had not thought of NB improvements in the same light as KDSP2 costs. It would be nice to think of the K2 as an evolving design, but have not noticed much evidence of that recently. Small CW rigs seem to be the way it's going. 73 Stewart G3RXQ On Sun, 13 Feb 2005 14:35:31 +0000, Marinos Markomanolakis, M.D. wrote: > A comment about the K2NB and the different reasons that we perceive as being > > responsible for the lack of its improvement: > Just how much would an optimized NB design cost as to become prohibitive for > the average Elecraft customer ???

Hi Stewart,
I have to admit that fortunately the K2 has been a design in progress at least for the last 4 years that I know about Elecraft and its products. My 1st K2 was serial# 26xx, and having built my 2nd one recently #4618, I have seen many significant improvements. This is the greatest thing about this radio: Improved versions are adopted, but the earlier models remain upgradable and you do not have to worry about buying another K2 down the road in order to get the newer version (eg 756 "family"). I really do not think that the K2NB will become the exception to this, and I am happy to see some immediate positive comments from Wayne, N6KR about the project. I personally can not point to a specific design source that Elecraft can hire to help, but have an interesting idea: What if Elecraft declared a K2NB "design contest", where every one with the necessary technical background would be welcome to experiment and then submit his final design to Elecraft for evaluation. The best design could be selected and the inventor rewarded with a specific winning price..... This way everyone can be benefited and we can expect to see an improvement within a reasonable time frame. Just some (maybe crazy) ideas.

Gee, my K2 #402 is going gangbusters and I still haven't done any mods yet.
I can't imagine it having better basic performance. I hear those original test batch K2s (under sn 100) still kick ass too. I think the basic performance hasn't really changed much. I don’t think it can get much better.

I've upgraded a couple old K2 including one for a friend that was Serial #
5** and you'd be suprised at the performance after the upgrades. One upgrade may not do a lot but if you bring your early K2 up to current level it'll blow your socks off compared to what you have now. Not to Dis the unit you now have as we all know they are great rigs, but what's wrong with making a great rig better? Gregg R.

This is a GREAT idea! There are so many extremely technically gifted guys
and gals out there with a keen interest in Elecraft and the K2 that I'll bet it would be a huge success! Alas, I'm not one of the technically gifted so I can't do a thing with the design but would be very willing to be a beta tester! Thanks for suggesting it! 73 es gud dx --don n4hh K2/100 #2028, KAT100, etc, etc! ----- Original Message ----- From: "Marinos Markomanolakis, M.D." <[hidden email]> To: <[hidden email]> Cc: <[hidden email]> Sent: Sunday, February 13, 2005 1:41 PM Subject: [Elecraft] K2 NB design contest ? <snip>. > > This is the greatest thing about this radio: Improved versions are adopted, > but the earlier models remain upgradable and you do not have to worry about > buying another K2 down the road in order to get the newer version (eg 756 > "family"). <snip> > What if Elecraft declared a K2NB "design contest", where every one with the > necessary technical background would be welcome to experiment and then > submit his final design to Elecraft for evaluation.

Well I guess there's the SSB crystal mod, and the ones to make it better
with the amp, and the keying one for PSK, but I don't recall one mod yet that would improve the basic QRP CW rig receiver-wise. I think the Elecraft team designed a great radio to begin with, and made sure it was good before they released it, and the mods are more to accommodate a lot of the options that came later. I am doing OK in the Foxhunts and don't want to change a good thing. In other words, I don't want to chance messing up the rig right now. ;.) If the performance problem was on CW, perhaps your friend's sn 5** rig was not aligned correctly originally.

Actually I had to repair and align his rig before I even attempted to do any
upgrades (he bought it that way, not in very good shape). But even for CW upgrading the CW waveform and doing the Stability mod and the xtal filter upgrades will improve things quite a bit. Gregg R.

It was built by one of the "high volume" builders on this list since I have a few disabilities that make building close to impossible. So, if there are any builders who do work for elderly/disable folks...let me know what you think should be done a unit of that vintage. It has ssb, 160, nb and the battery. 73, Thom k3hrn _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Morning Marinos,
Very interesting thoughts. There must be a huge pool of technical knowledge and practical know-how amongst Elecraft's customers, a powerful combination. Now if we could also eliminate storm static QRN - a tough nut to crack !! 73, Geoff GM4ESD ----- Original Message ----- From: "Marinos Markomanolakis, M.D." <[hidden email]> To: <[hidden email]> Cc: <[hidden email]> Sent: Sunday, February 13, 2005 2:35 PM Subject: K2 NB > A comment about the K2NB and the different reasons that we perceive as being > responsible for the lack of its improvement: > Just how much would an optimized NB design cost as to become prohibitive for > the average Elecraft customer ???
