my screen looks like with V1.3559. Can't use the menu.

You need a very sharp pen to reach the corner. It's not healthy for the touchscreen to use a sharp pen. Thanks very much! -- Klaus, DL5KV

Jeff, That's right, impedance matching is necessary for sources that can only deliver a small amount of electrical power and whose power is to be passed on as comprehensively as possible. Such weak

Erik, The build instructions will build a version "v0.1-602-gb87733e" based on the deprecated "master" branch. The most important info to be on track with your development is to type *git checkout

That is not the case. Most Pas are not 50ohm, they are designed to give a specified power 'into* a 50 ohm load. The o/p impedance of the PA has no effect on any reflections from the load, that is

Paul, I believe that you need a second device to act as the generator.? If you do need a second device, it would be my recommendation to get one that does VNA functions.? The NanoVNA series is in

New ULTRA FW release Version V1.3559 Changes: - Removed slash in zero in medium font for better readability - Shifted touch cal points away from display edges - Added level checks during level

do these have a tg or anyway of hooking one up,for bandpass filter alignment etc?,73 m3vuv.

I've updated the build instructions on github https://github.com/erikkaashoek/tinySA/blob/master/README.md For the ultra you should use this: make TARGET="F303" -- For more info on the tinySA go to

Hi, Lane, The project uses built-in C preprocessor directives for conditional compilation when built from the main branch. Would you, please, share some details of Your proper toolchain setup under

Lane, Please see my issue #35: https://github.com/erikkaashoek/tinySA/issues/35 Martin

I have managed to get the source code to compile in a Windows 10 environment. I thought that the "V4.3" branch was the one to use, but seeing an older version displayed in the CONFIG->VERSION screen.

I've also found the output power of an HT is dependent on the charge level of the included batteries. This can change from one transmission to another transmission and even within a long-winded

Excellent explanation. Brings back many lab experiences. Kind Regards, Dave Dave Reiser, WA3TRS Sent: Tuesday, December 13, 2022 5:30 PM To: [email protected] Subject: Re: [tinysa] #tinysa Power

The main problem with this power measurements is that also if the power meter and the attenuator are in good condition the measurements can be vary a lot. The reason is that a HT has in most cases not

Yes, will be done -- For more info on the tinySA go to https://tinysa.org/wiki/

You need to touch the corners in order for the cal routine to do a measurement across the entire screen.? Use a plastic tipped mechanical pencil with the lead retracted, the rounded end of a

It's nearly not possible to calibrate it with good quality. I wrote it here ( /g/tinysa/message/8569 ) It would be nice if there will be a change in future. -- Klaus, DL5KV

Please do a touch calibration. CONFIG/TOUCH Make you touch exactly in the corners with something like a wooden toothpick to het the best touch calibration If that does not improve relax the case
