Ron, Nada here at 16:46 wrong MUF for my qth
-
2 of my BBAI upgraded w/o a issue... one per schedule, one I forced
-
if you're running WD.. let me know so I can include you on my ranking analysis. See ranking page and my e-mail contact at http://www.wa2zkd.net:8088

Hope you get better John....
-
kiwisdr and upgrade are usually PnP but that first one got problematic along the way
-
I have some loops I made using fiberglass fishing net hoops inside of tubular braid. Flexible yet hold their shape rather well.
-
replace the unwieldy brown wire with a simple piece of #14 bus wire
-
I don't like touching a soldering iron to my kiwi or BB so got some DC blocks from eBay. But, I'll DIY my next ones. A 15 or 18 pF series cap would work. I don't think the kiwi cares about antenna sensing, so that simple cap should suffice.

sytem running very well for 5+ days and my wspr spots have improved... seems like less RFI
-
I am a fan of used Acopian Linear supplies. Industrial quality at a reasonable price. May you have access to them or similar in the UK https://www.ebay.com/sch/i.html?_fsrp=1&_sacat=0&_nkw=acopian+5v&_from=R40&rt=nc&LH_TitleDes…

it's "normal"
-
Yuri, Given the 33-34 deg temps I am seeing, I doubt that I will see an issue.
-
BBAI has connman already installed. Has anyone tried adding connman to the BBG?
-
all systems running now... 2 unloaded kiwi/BBAI run 31 deg. and the 2 with 14 channels of continuous kiwiclient run 34 deg, in my cool basement
-
http://www.jimlill.com:8073 and 8075 are the public access boxes and now both back online. 8073 is on a Mag Loop and does 3 X 20 KHz channel mode 8075 is on a vertical dipole and does 2+6 X 12 KHz channel mode
-
thanks for the heads up.....
-
Project is done mechanically, just needed to update the firmware in everything, configure and hook up antennas. Pix may be viewed at https://www.dropbox.com/sh/x7tt18loi84bpg3/AADLeN3iU6g7ZoPi520opbQpa?dl=0

I assume they are all "behind" the same router, kiwi and Pi. How do you handle your 192.168.x.x. (or 10.10.x.x) IP # assignment? DHCP. Static or ? I lock the device MAC to IP# in the router and let the device run DHCP. I wonder if your L…

got it running here... will have to use it some..
-
Besides offering up to 56 simultaneous connections/channels this allows use of up to four antennas or filtered antenna paths. I have had 4 kiwis running for months, but never mechanically integrated like this. I use 2 of them for wspr, a different …

this is now obsolete (Image)
-
Almost ready... removed paper ducts and with 4X 14 ch installed max temp at 100% CPU is 44 deg C, a 19C rise

-
It is adequate the way it is, so don't want to complicate it. The simple addition of that paper deflector was worth 1 deg !
-
Yes, I know what heatpipes are and perhaps I misstated that. By in effect, I meant it draws heat from the hotspot...
-
I'm not sure that my bends in those pieces make any real difference. They could be fab'd from 1/4X1/4 aluminum (or copper) stock. They are in effect a heat pipe.
-
Pi-hole might do it https://pi-hole.net/
-
simple alum. and yes I designed it and made them with a water-cutter. I'll publish the drawing. I have that cardboard baffle there to defleact the air to a more favorable path.
-
I have a Kiwi cluster of four units mounted on a single end plate. On that is a plenum/fan-mount with a single 80 mm fan. Testing, so far, shows the CPU temp never exceeds 46 deg even with heavy loading. (Image)

* combined with a virtual audio cable something like https://www.qsl.net/dl4yhf/spectra1.html provides a lot of tool. * https://www.audacityteam.org/ is another good tool * and of course there's something better that I can't think of!! :-)
