You made calibration, and after you measure calibration load on this device and get 50 Om? Or you measure calibration load on different device?

Hi, which firmware have you used? I found out that the newest cloned firmwares for the SAA2 has a worse quality than older. The firmwares until Sept. 2020 are OK. Later versions are not usable. I

load measured 50.1 on my VOM as soon as I say DONE it starts is there a repair facility anywhere? Silly thing, I really liked using it for antenna analysis. sigh..

Yes. 5W is +37 dBm. This attenuator can handle 5W continuously, and its 41 dB attenuation will reduce the transmitter signal to -4 dBm. The TinySA max input power is +10 dBm with its internal

So, in theory an attenuator like this connected between a 5W transmitter and TinySA would work? http://www.qrpkits.com/attenuator.html

Need check calibration kit/RF connectors/cable If before calibration all look good, i think problem in 50 Om calibration, check it

This is what it does immediately after I save the cal data to 0 slot. Wow

ok it accepted config and all data cleared... yea So far so good.. 73 Paul

HI Roger got it into terminal mode and ran Clearconfig but its not happy w the "1234" Then what ???

The file you want is NanoVNA-App.rar. It is a rar archive, which is similar to a ZIP. 73 -Jim NU0C "paul kobetz" <pkobetz@...> wrote:

Forgot to ask, what's this legendary piece of equipment, it has transistors so it can't be that good ?

Not the one on the right. See my previous post. 73 -Jim NU0C "Dragan Milivojevic" <d.milivojevic@...> wrote:

Yeah, I remembered that about the one on the left after I sent the pic. The one on the right he called a "buzz kill". 73 -Jim NU0C "Bob Albert via groups.io" <bob91343@...> wrote:

Can you connect to the NanoVNA-H with the NanoVNA Sharp program? Do a calibration and remember to press Reset before you start and Done when you are finished. Save to a slot like 4. Then see if you

The left hand one is bypassed with a .01 so that doesn't count.? I am puzzled by the other one; what's it supposed to do?

And yet here we have two electrolytics in an RF circuit in a legendary piece of ham gear. I asked an actual rocket scientist about it and he didn't think it was anything unusual. 73 -Jim NU0C "Dragan

Paul, Make sure you didn't turn OFF the calibration on the unit. In the calibration menu there is an Apply checkbox...make sure it's checked. However, with that said, sometimes it flips a bit and if
