bit bucket is limited to 5 collaborators and limits the project size.
git lab removes those limits. 



out of those two I would chose gitlab every time. for a while I had my own gitlab server, but just started using their cloud server as it made more sense.

if you think about these two: gitlab or bitbucket - which one will you

prefer and why ?



I didn't see any limit on amount of active developers for persnal/small

teams case. I missed it ?

yep, either that or  GitHub , "free to use for public and open source projects" - I don't see why you should be limited to 5 contributors, hopefully there will be much more :) .

Just forgot to write.... add the Gcode or CamBam files in your repository too :- O



Nice piece of mechanical stuff

I reckon that a single person having known software reference - I mean

genuine msa and working hardware can hardly do this in a year unless

fully committed.

Hi Krzysztof



Perfect. Dxf is a perfect "all purpose" format for cam/cad



>> Did you put you source on github ? it could definitely help if some

>> other guys want to fork/contribute

>yes, i have done this just a while ago.

>hmm, ok, who are they ?



We run a "build group" in our hackerspace 7 years ago (for a total of 15 analyzers, VNA config). Some of the builders are professional developers in the embedded RF hardware domain (SDR, instrumentation and measurement etc). Many (unfinished) projects where considering adding some FPGA for signal analysis. Some finished projects where too much "forking" and personal to remain compatible with the main MSA architecture.



Anyhow, I'll keep them informed , I'm pretty sure most of them don't follow this M.L.



Cheers

Marc

Yes. It is not straight way to get dxf from eagle 5.x. 

I need to use hpgl format, then convert to dxf using old and incomplete

tool: hpgl-dxf project. It was missing arcs processing so I fixed it.



Then I use QCad which I owe too. With this, good enough tool, I can

assemble many dxfs into multi-layer final dxf.



That's it. Bit time consuming.

gitlab. I created a group "msa4linux". It is private by now.

Looks like it is noble community of professionals.

Yes, please. Give us some time to stabilize the gitlab repo and I

reckon we give access to wider auditory.

so, are you sure you want to follow my way ? I was talking about two

unique modules and actually there is 3rd one I forgot. It is RBW

filter. I'm going to use 2x1 module with 2 paths: "mid-narrow" about 6-

7.5k BW which depends on fine tuning load capacitance for typical

crystal filter. Second path is "narrow" of abt 400 - 600Hz - I am going

to use mccoy filter despite of that it is temperature sensitive and

difficult to figure out its impedance in pass band.



And even 4-th one: the mxr2 and preamp. I merged these two together and

used bridge-tee LC filter between. Two genuine mxr2 and preamp modules

will fit also.



Here is quite interesting story how to make such filter with insertion

loss < 3dB or even 5dB when inductors are really poor.





I sent a "picture-drawing" of rf cables layout which hopefully will

help to recognize which module is which. The cavity filter will be

fixed to the bottom.



My HW and chassis doesn't follow Scotty's design very strictly thus

some modules won't fit.



Also supply unit on the top will likely deliver +5@1.3A instead of

+20@20mA for PLOs. I'm going to use modern pll-vco combo single chips.



So lots of exciting hw tests ahead.
