General Discussion / Re: Merry Christmas!
« Last post by cockpitbob on January 08, 2018, 10:51:32 AM »
Merry Christmas and Happy New Year everyone! ;D

All I wanted for Christmas was some time with the family out of the house so I could throw breakers and track down why I have S7 to S9 broadband background noise :P

I got my wish, but it didn't work out the way I hoped.  Last year when I threw the main breaker the S7 to S9 noise would go to S2 or less.  Now it looks like my neighbors are making noise too because now the noise only drops 1 to 3 S-units when I throw the breaker.  Having their noise mixed with mine will make it harder and less useful to find my noise sources ???.  Funny, but I'm looking forward to the next major power outage.  I'll run my house on my generator and the only noise sources will be mine.

It's a good thing CW gets through almost anything ;)

Gil, I just renewed :), a few months late.  I'm always late with this kind of thing unless I'm sent a reminder ???.  If there's any way to set things for reminders when the subscription is about to expire that will help.

Thanks Bob.
Just out of interest, how much does it cost to print a box?
I have a 3D printer and for the common materials (PLA or ABS) it's about $0.75/oz.  It's even cheaper than you might think because for areas of an item that have a lot of volume you tell the printer software to fill the areas with honeycomb of whatever density you want.  I use anything from 20% "infill" to 100% infill.  It saves weight, materials, print time and you lose very little strength.

Printing is a slow process.  I think printing all the parts for a uBITX box would be about 15hrs of printer time.  That's OK since it takes 5 minutes to set up a print, then I just let it run over night.

For what it's worth, there are two 3D printable cases for the uBITX on thingiverse

I've made a couple cases for RF stuff on my 3D printer.  For shielding I line it with copper tape.  This makes for a very light enclosure.  12feet of 1" copper tape is only $3 on banggood.com.

That looks great for the price!  This really is the glory days of Ham Radio!

Give some thought to the uBITX.  It's an all HF band, 10W radio, except no box.  For $109 you get a fully tested set of boards you wire up in whatever box you want.

If you know someone with a 3D printer, there's already 2 enclosure designs posted on thingiverse.com

If you're a builder like me, starting about a year ago I began feeling like a kid in a candy store with too much to choose from ;D
