Now I realize I asked a dumb question below as IMSAI Guy is very clear in his videos that we need to buy a cheap demo board and remove those parts to put on his SMA board v2. A Sparkfun tutorial about U.FL connectors, like on the demo boards, refers to one data sheet where Hirose tested those connectors only 30 times. If these tiny connectors do not last well, then it would be easy to "use up" the demo board connectors and cables just calibrating your nanoVNA. I did purchase an SMA board and will build up the necessary components from scratch. I'm not sure yet how to source the Epcos 433 MHz BPF, and I'm not sure about a couple other circuits but this will be a good learning thing and eventually I'll have a much more useful test board with SMAs. Glad you made a PC board.
In some of the new firmware , there’s now a step for an Isolation Calibration. Is tha a 50ohm load on each port or it it a 50 ohm load at the end of a length of coax on each port. I’ve found literature that say both as well as a couple procedures that make no sense at all. Thanks for your time/ Jason Burchell
@@IMSAIGuy It is really too bad that there is not a list of parts (like many of the other PCBWay shared projects) so that we could construct a "clean" board from scratch. I have ordered your PCB boards and will attempt to slowly add the proper components.
@@IMSAIGuy good point when looking at all effort required, but you did a really great job and inspires me even more into completing my last 6mnths of telecommunications technician course
I AM SOLD !!!! Since I am a clumsy old fool with gorilla hands and ankylosing spondylitis, I will require the 7/16" DIN connector version. Please -- Pretty Please ! Ok.. I'll settle for "SMA" :) Are you anywhere near NYC/NJ ? I have a Motorola Quantar repeater (traded a Tahoe for a pair of 'em) and never managed to get it on the air before arthritis and retirement set in. I'd love to donate to the channel for your review/analysis/ and , finally.. blowing it up ;) I'll throw in a duplexer for your new "Tune a Duplexer in a moving vehicle" video series. Thanks so much for your videos. You have made an old guy quite happy during the Triple-Mask LockDown Challenge. Seriously.. Thank you.
@@IMSAIGuy you MIGHT still have time to escape!! 😔I’m one to talk... I’m stuck in the PRNJ (“People’s Republic of NJ) 😆🤣 I have learned so much from your channel. You missed your calling in life... You should have been a TEACHER (or Tik-Tok electronics model 😉😳) All kidding aside, you explain things in a very well thought out way, with good video imaging to accompany your tutelage. Have you dabbled in the DMR digital radio world yet? I have been playing around with it and with “hot spots” as of late. The TGIF network is fairly new and very flexible in terms of getting talk groups created. Thanks again to a great “Internet Elmer” !

I'd be interested in it.
gerbers link are in the description
Alan, send me your address and I mail out a board.

great vdieo. I purchased some boards. What kind of sma connectors are you using and where did you ge them. Thank you.
vertical PCB mount SMA, I get them on aliexpress or eBay

isolation is to be done with 50ohm loads on all ports. it measures the internal crosstalk of signals.
@@IMSAIGuy Thanks!!
A friend share the diagram. What components need to be soldered apart from connectors?
dang, I thought this was available somewhere to buy, completed.
My lab isn't set up yet...otherwise, no problem.
yay. this is what we waiting for
part number of connectors in Mouser or digi-key? I'd hate to order a bunch and they not fit.
I got them off ebay from china. I think they are all the same
@@IMSAIGuy Thanks
Is there a list of the components for this board. I can figure out some of the simpler stuff but not which chip is the 433 BP and a few other things.
I bought a $15 demo board and removed the parts and soldered them do this one. the parts vary from vendor to vendor on those demo boards.

Friend! Is there a schematic diagram or a bom?
no, you buy a SMD board and transfer the parts
@@IMSAIGuy You misunderstood. I need the denominations that need to be soldered.
@@EW7DDR you misunderstood. there is no BOM.
Next.... the N connector version. :)
wow, that would be heavy duty!
@@IMSAIGuy What we really need here is an APC-7 connector version :P
@@linuxaos send me to the poor house...
Would you ever consider making another sma version and mail to Canada? If so let me know how much as i definitely would like one
the link to the gerber files are in the description so you can get a board made. I'm not going to build any more completed ones
