When you really want an enclosure, though, I haven't seen any that match what Heinz HB9BCB has done.

RE: [Elecraft] W1 Questions
Hi Mark: The mini-kits were designed for low cost and ease of use on the bench, hence no enclosures. The W1 works just fine sitting on the little feet supplied. That said, one fellow W8FGU wanted an enclosure and created a spiffy one made of lexan for the W1 (and some other mini-module kits) that he offered for sale. Check here. No changes to the W1 are needed other than to mount the battery on the bottom and the BNCs on the top of the board as shown in the pictures. http://w8fgu.home.comcast.net/~w8fgu/pics/enclosures/W1/w1enclosure.pdf It's really handy if you're going to drag the W1 around away from the bench, throw it in a bag, etc. The W1 is a handy, useful and it accurate addition to my bench after calibrating it simply by setting a d-c voltage as the instructions say.

RE: [Elecraft] W1 Questions
I like the W1, and it works just fine here. Do not have it in any kind of enclosure. It is mounted on the rear of my operating desk such that it is at the correct angle for a good view of the display LEDs. This is accomplished with a couple pieces of clear packaging tape around the input and output coax connections. I power it from the external 12V line from my K3 so that it powers up with the K3. One hint that VASTLY improves the usability. When you build it, replace the first 6 LEDs on the row of SWR indicators with different colors. I use green LEDs for 1.1, 1.2 and 1.3; yellow LEDs for 1.5 and 1.7; and an orange LED for 2.0. This way you can instantly see the status of your SWR at a distance without needing to read the very fine print on the PCB. With all red LEDs as supplied by Elecraft the display isn't very user-friendly. The replacement LEDs are readily and inexpensively available from Mouser or other vendors. ...

RE: [Elecraft] W1 Questions
>>I'm getting ready to build my W1 SWR/Watt meter. Before I start, are things I should consider. Enclosure? Mounting BNC off-board? External power? COM port mounting? I have mine sitting out on my desk without an enclosure. I use it with a K1, with an IC-746Pro, and a buddy's K2. Indoors, sitting on the desk seems to work fine. I had it with me at Field Day and it worked fine sitting on bench table in a park feeding off my K1. You certainly can put the W1 in an enclosure. However, it probably needs to be a clear enclosure since there are display lights at the top of the board and also on the left edge below the middle of the board (which is also where the on-off switch is located, which means that you'll need access to the switch). Obviously, if you put it in an enclosure, you have to worry about whether or not any conducting surfaces of the enclosure might touch any of the components (especially the BNC connectors). The feet on the W1 will keep anything from touching the bottom, but it might be tricky to isolate the BNC connectors. If you're going to mount the BNC's off the board, your connection between the BNCs and the board would have to be of a type that prevents adding loss and SWR. If you're going to do something like that, you might consider mounting the BNCs on the board as per the instructions, and then short coax jumpers out of those BNCs terminating in BNC females. You would then connect your rig and antenna to the external ends of the jumpers. My impression from others I've talked with is that most people have some sort of a carrying case, but then use the W1 without an enclosure when they need to use it. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re [Elecraft] W1 Questions
Hi Mark, The W1 is a great tool and I am sure that you will find it very useful. Construction was very straight forward and mine worked right from the start. Since I use it only occasionally to test antennas, tuners, and rig output, I did not put it in an enclosure. The board simply sits on it's rubber feet on the desk while I run my tests. If you are planning on a more permanent setup at your operating position you might want to consider the custom enclosures at http://w8fgu.home.comcast.net/~w8fgu/w1encl.html . I don't have any personal experience with these boxes but they look very good. 73, Paul - N8XMS ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
