K2/SSB Construction
Locked
 
|
I just ordered a K2 and SSB adaptor so while I'm anxiously waiting
delivery I'm trying to get the shack and bench ready for construction. I've downloaded and briefly read the manuals and I've come up with two questions (the first of many I'm sure). 1. Are there any mods (part additions or deletions) that need to be done to the base K2 if the SSB adaptor is going to be added? Is there anything I should watch out for to prepare the K2 for the SSB board? 2. Are there any recommendations for a vise to hold the PC boards during construction. I've got access to a Panavise with about 6" capacity jaws; is this big enough? Any thoughts will be appreciated. Thanks for the help.

Nothing special on my side. Just be sure to your kit include the latest mods
about the SSB bandwidth... 2.4 kHz instead of 2.2 kHz... Should be there now on lastest version. Be sure to pay attention at the toroids... They are smaller than those in the K2, and the enamel wire is easely scratchable... ;-) And also be carefully to ground the xtals properly.... 73 -----Message d'origine----- De : [hidden email] [mailto:[hidden email]] De la part de Craig Miller Envoyé : 28 février 2005 08:37 À : Elecraft List Objet : [Elecraft] K2/SSB Construction I just ordered a K2 and SSB adaptor so while I'm anxiously waiting delivery I'm trying to get the shack and bench ready for construction.

Craig,
The kit you will receive will be totally up to date, so you need not add any mods to bring it up to level. OTOH, if you have special needs or desires to make the K2 behave in a manner slightly different than normal, there are a number of mods that you can add to do just that - but wait until you have a good running 'stock' K2 before making such changes. You should just follow the instructions in the manual - there are sections in the K2 manual telling you what, how and when to add the Front Panel and RF board components for the KSB2 option. You will find the Elecraft manuals well written and easy to follow (unlike many other kits - including a TenTec 'beginner's' regen receiver kit that I recently assembled with my grandson). As far as a vise goes, your Panavise will likely suffice. I really don't like those 'holder thingys' for most boards because it makes flipping the board over for soldering, etc. more cumbersome - I simply work with the board loose on the workbench top which allows me to position the board quickly whichever way I need at the moment - but each to his own, that is just the way I do it. 73, Don W3FPR > -----Original Message----- > > I just ordered a K2 and SSB adaptor so while I'm anxiously waiting > delivery I'm trying to get the shack and bench ready for construction. > I've downloaded and briefly read the manuals and I've come up with > two questions (the first of many I'm sure). > 1.

Craig,
If you read the manual for the K2 and find the section which discusses building the display board you will find that you can mount some of the display parts for the KSB2 when you build the Display board.......I started off using an ANTEX PCB holder to build the Control board until I mounted one of the resistor arrays which is very close to the edge of the PCB and this made it impossible to use the PCB holder....not sure which one you have so your mileage may vary..

Something to watch out for:
The KSB2 manual tells you which set of bypass capacitors to install on the front panel board on page 1. However, the K2 manual rev F on p.28 directs you to p.16 of the KSB2 manual, which doesn't warn you that there are two sets of caps of different sizes.

Leigh,
I do not have the manuals with me but i feel sure that the 5 brown 103 caps do the job...soldered them in on Saturday afternoon....

Fully agree with Don about those 'holder thingys'. For large PCBs I use a
method similar to Don's, but attach hexagonal spacers through the PCB holes that will be used for mounting the PCB. At each PCB mounting hole I thread through the male portion of a spacer from one side of the PCB, and pick it up with the female end of a spacer on the other side. The length of each spacer, usually made from a few spacers threaded together, is a bit longer, say one inch or a little less, than the hight of the tallest component to be mounted on that side of the PCB. So you end up with something that looks like an oil derrick, and the "free" ends of the spacers become feet for when the top of the PCB is up or down. You can also "peek" under the PCB. With a large board it is a good idea to have a spacer thing near the middle to add support. The board is very well supported and easily moved around, or flipped, but a price is that when you want to install the PCB for tests, all the spacers have to be taken off. Caution, don't over tighten the spacers at the PCB, finger tight is fine. For small boards I either do as Don does or use a single spacer thing in turn clamped by a vice. I prefer Don's method for HF but for UHF prefer the clamp. BTW I use metal spacers because Murphy is sure to make me burn plastic with the iron. Useful items for the Junk Box. Good luck es 73, Geoff.

You can add the connectors for the SSB board when building the K2, which will save you a bit of disassembly and reassembly later. The K2 manual will tell you what to install, and when. There are a couple parts to remove, but it is a good idea to build the K2 without any options and get it working first, then add the options, so don't worry about those until it's time to install the SSB board. -- 73, Brian VE7NGR _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

i'll be ordering the k2 and internal tuner within the month. tnx for the
notes and the info. was bantering on which "options" to order. 73 mike ku4yp Brian Mury wrote: > On Mon, 2005-28-02 at 08:36 -0500, Craig Miller wrote: > >>1.
