Resetting K2?
Locked
 
|
I have to replace a questionalble KNB2 NB option,
pcb card (populated). Is there someway the K2 (#5422) needs or can be RESET - to first know that, once I pull out existing KNB2 option card, it again doesn't have one - and then when I put new KNB2 populated card back in - it knows again a KNB2 exists? Wow - long winded, for "can I reset my K2?" I'd like to clear the K2's throat, before I put another option card back in. :>) Thanks, Fred N3CSY 6/27 __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

Yes, you can reset your K2, and
NO, don't reset your K2. Reset clears far more than you want/need to clear. The K2 will know the option is missing when it doesn't answer on the AUX BUS at power-up. Likewise, it will know when it's reinstalled later.

Fred,
be carefull with the K2 reset... My friend tried to make keying circuit for K2 to be able to keying his K2 from PC with diodes 1N4148 or so. After turning ON the K2 completelly crashed on there was not possible to do anything except the factory reset. After factory reset the K2 had BFO frequencies out of range, TX does not work etc. :( After going thru the BFO settings procedure seems that RX works well again but I do not know what happened with TX during the factory reset. (anybody know please?) So I can recommend to be carefull with factory reset as You can spend long time with re-alignment Your K2. 73, Petr OK1RP > ------------ Původní zpráva ------------ > Od: Fred (FL) <[hidden email]> > Předmět: [Elecraft] Resetting K2? > Datum: 27.6.2006 14:11:38 > ---------------------------------------- > I have to replace a questionalble KNB2 NB option, > pcb card (populated). > > Is there someway the K2 (#5422) needs or can be > RESET - to first know that, once I pull out existing > KNB2 option card, it again doesn't have one - and > then when I put new KNB2 populated card back in - > it knows again a KNB2 exists? > > Wow - long winded, for "can I reset my K2?"

Fred,
In a word, NO!!! Do not do a reset - you will have to re-enter all the settings for filters/BFOs, and any other parameters you have so carefully set into your K2. The firmware handles removal and replacement of options automatically with the AUXBUS signalling, you do not have to do anything to make that happen. While we are on the subject - if you have not done so, it is a good idea to write down the settings for these parameters. Download the A to B instructions from the Elecraft website, and you will find it has a nice chart where you can enter your filter settings an other menu items just in case something happens along the way and you have to re-enter them. 73, Don W3FPR > -----Original Message----- > > I have to replace a questionalble KNB2 NB option, > pcb card (populated). > > Is there someway the K2 (#5422) needs or can be > RESET - to first know that, once I pull out existing > KNB2 option card, it again doesn't have one - and > then when I put new KNB2 populated card back in - > it knows again a KNB2 exists? > > Wow - long winded, for "can I reset my K2?"

Don - Thanks for the "reset warnings"! I haven't done that yet. I'm in the middle of re-building a new KNB2 that Elecraft's support group sent me. For some reason - existing KNB2 seems to do little with noise. Had a series of cement trucks out front last week, MUCH MUCH ignition noise - the KNB2 I have in here now - did nothing to remove or reduce it? (20m, 40m) And this K2 aligned very nicely - and seems extra sensitive, etc. I did the whole Spectrogram 5.7 thing. (with your help!) I'd just like to make sure my K2 # 5422 - "knows" that a new KNB2 option is installed. And "clears it's throat", etc. 73's Fred N3CSY US/Canadian border - St. Lawrence River upstate NY 6/27 --- Don Wilhelm <[hidden email]> wrote: > Fred, > > In a word, NO!!! > Do not do a reset - you will have to re-enter all > the settings for > filters/BFOs, and any other parameters you have so > carefully set into your > K2. > > The firmware handles removal and replacement of > options automatically with > the AUXBUS signalling, you do not have to do > anything to make that happen. > > While we are on the subject - if you have not done > so, it is a good idea to > write down the settings for these parameters. > Download the A to B > instructions from the Elecraft website, and you will > find it has a nice > chart where you can enter your filter settings an > other menu items just in > case something happens along the way and you have to > re-enter them. > > 73, > Don W3FPR > > > > -----Original Message----- > > > > I have to replace a questionalble KNB2 NB option, > > pcb card (populated). > > > > Is there someway the K2 (#5422) needs or can be > > RESET - to first know that, once I pull out > existing > > KNB2 option card, it again doesn't have one - and > > then when I put new KNB2 populated card back in - > > it knows again a KNB2 exists? > > > > Wow - long winded, for "can I reset my K2?"
