I didn't do it that way.... I put the FH screws in case put a piece of tape over them, put star washer over them, dropped board stack on, then tightened the FH screws. I have done about 10 kiwi that way
-
you can use this command systemctl restart ssh.service from the console window of the kiwi admin

IT IS PERSISTANT

I have access to a pro-grade IR camera system as used in a development lab for new designs. I'll see if I can get it to use.

I live in a RF swamp. I have 4 AM BC within 2 miles, all local TV BC within a 1/2 mile and a few FM BC thrown in. Any small aperture HF antenna is large for VHF and above so an LNA at the feedpoint gets pummeled. My current project is converting a…

WRT to the MC parts.... I added some of those here and felt that my MW and lower HF performamnce degraded. I split my current antenna 3-ways and a kiwi with and w/o to compare. There is also this for review https://www.qsl.net/wa1ion/bev/bb_anten…

Yaesu AGC and S-meter readings have a history. I have had a few of their rigs and the older stuff seemed like the AGC drove the S-meter, and little else. Surely the IF/audio gain was not well controlled. The gain controlling has gotten better but m…

beware of the Mini-Circuit parts if you live where RF fields are high. I live in a swamp of MW, VHF, and UHF BC TX and have found that lesser ferrite can create more issues than they solve.
-
Which halo parts are you using?
-
as long as the changes can be customized by the kiwi owner.... I am OK as-is size wise
-
Yes that's the way to do a quick check which is all what many people with do.
-
what does the [SPEC] display show on a the user webpage?
-
you might try one of these for your CM issue https://www.minicircuits.com/WebStore/dashboard.html?model=T1-6%2B

the impromptu WSPR Challenge is so much fun...! :-)
-
I have made my site "public" now, my announcing it on wsprnet. The progress files are still there but the URL is not apparent anymore.
-
Does anyone have data characterizing various magnetic loops that include their own LNA?
-
FWIW, on a wspr-only system I think you can have 2 different antennas for the bottom and top of the LF-HF spectrum by using LPF and HPF filters and combining the outputs to go to kiwi. Just make sure the outputs aren't such that the "opposite&q…

WRT to waterfall.... channel 0 still has it and you can shut off 2200M during daylight hours to do other testing
-
I didn't add any heatsinks, just blowing 42 cfm through the "tunnel"
-
step 2, complete (Image)
-
No. Cloud9 was on 80 until I killed it.
-
I disabled the Cloud9 stuff and all is better sudo systemctl stop cloud9.service || true sudo systemctl stop cloud9.socket || true
-
It happened again and in fiddling I found myself in the Cloud9 webpage. OS and shell running fine BTW
-
OK, a little fiddling with reloads etc. and it is OK
-
Have things running here. 42degC so OK, will make it better later. KiwiSDR webpage come sup, have audio. But can't get into admin page with xxx.xxx.xx.xx:8073/admin
-
maybe BBAI2 can address that heat issue and change the DRAM to 2G. I use an Odroid XU4 on one of my wspr loggers which is sans HDD or SDD and use 1G of DRAM as a RAMdrive to save emmc wear. I'd guess other projects could benefit from same.
-
I'm taking a "just add air" approach. (Image) - removed internal fan - mounted BBAI on 1/4" standoffs - raised cape with extension headers - mounted fan from slot cooler on modified endplate - flipped and modified opposite endpl…
-
regarding the getting a 46 pin header on..... I got out some ext. headers I had for an RPi and they are < 46 but then a Kiwi cape is even less, so you don't need to deal with all 46, just the Kiwi pin count making it easier
-
Cooling: I intend to use much more forced air...
