John Grow, VE2EQL gave a talk at this month's meeting on Surface Mount Technology (SMT) and SMT Kit building. He gave out a handout with various links.  Here are few of them:

SMT Kits and Building.

In addition,  John sent this message to me on Thursday morning.

Subject: Forward: [QRP-L] New NorCal Kit Announcement

Jim & Vern,

Follow-up to my session last evening of SMT and SMT Kits, NORCAL has announced a SMT Dummy Load with features.  I would be willing to do a group buy and send it to my USA address.  Then the kit could be built as a group build project.  If you want to send this to the list to generate interest, I have no problem running with it.

The cost of the kit is $ 10.00 US.

The NorCal QRP Club is pleased to announce their latest kit, the NorCal SMT Dummy Load kit.  This kit contains everything you need to build a QRP Dummy Load, using surface mount parts.  There are several surface mount kits available today, but there are some builders out there who are not sure that they are capable of dealing with surface mount parts.  They have probably held off buying some of these new kits because of their fears.  Now they have the opportunity to experience surface mount construction at a very cheap price.  When Tony Parks developed the SoftRock Receiver, he came up with the idea of doing a dummy load kit using 44 2.2K 1206 sized surface mount resistors to build a dummy load.  He did a few kits, but announced that he was discontinuing it last fall.  NorCal contacted him and asked if we could take the kit over and redesign it just a little and offer it as a kit from NorCal.  He very graciously agreed, and we would like to thank him for all of his help with the project.

Bob Okas, W3CD, was given the task of designing a dummy load, but also added a couple of features.  One, he added a detector circuit so that you could use it with a VOM meter to measure power.  Second, he added a third output pin so that you could use an RF Probe such as the North Texas QRP Club's Accuprobe kit, for even more accurate measurements.  Bob layed out the board, we tested it and now you see it.  The kit includes a double sided, plated through, silkscreened, soldermasked board that meets NorCal quality standards, 50 2.2K 1206 resistors, a .01uF 1206 capacitor, a 1N5711W SMT diode, and a through hole pc mount BNC connector.  All you have to provide is the labour and solder.  This is the cheapest kit that we have ever offered and think that it will be quite popular.  It is fun to build, and it does improve your soldering skills immensely. The kits are in stock and ready to ship immediately.  No waiting on this one.

This is an excellent first time kit for any builder.  It is easy to do, and you get a quality dummy load when you are finished.  Enjoy, Doug, KI6DS
