70dB is good. I use 80. But why turn off the LNA? Not that you need it with a direct connection to the HT, but I don't think it hurts the SA to leave it on...

Resent due to send error / no edit mode available. -------------- This question often gets asked. Here's my current test setup for measuring those ubiquitous 5w handheld rigs. At the antenna

It's amazing how well this Mac utility works...plug & play and makes updating NanoVNAs and tinySAs simple. 73 - Dino KL?S

Many thanks Erik ! It is working in very excellent way ! I started to test it since you post your kind replay, but I did not write about it's success immediately preferring instead to test it

From what I read in the service manual, all swept measurement are with RF in and measurement out at the same frequency. That's work that should be easy to do with a VNA as there is no frequency

Many thanks for the quick reply - I am impressed! It will be more very valuable for me if AGC in Listing mode is disabled. Want to use tinySA in connection with developing firmware for wireless radio

There is indeed an AGC active in the firmware This can easily be removed, or even be changed to user settable. -- Designer of the tinySA For more info go to https://tinysa.org/wiki

The VNA by itself should be suitable foe sweep alignment. But it is not plug and play. A method needs to be worked out that is safe for both the radio and the VNA and produces reaonable

Thank you martin, just uploaded the original PDF to the thread.

Thanks to chri5k for adding DFU-Buddy to the files section.? I wasted about 20 minutes trying to get my windows machine to recognize my TinySA.? Windows wouldn't even recognize the SA or let me

Hi Erik Thanks for reply regarding C85 - done :-) However, it does not work as expected :-( There is a lot of noise and in some cases it seems like that an AGC increases the sensitivity when there is

It is difficult to tell because part of the procedure is missing, and the resolution of the scanned page is not that good (Groups IO scales it). At first glance, it looks like a voltage output, or

Fine. Was this for TintSA app? Mike N2MS

Please ignore. Wrong group -- Designer of the tinySA For more info go to https://tinysa.org/wiki

I wondered a few days ago about the other message, too. What's this firmware for and where to find? -- Klaus, DL5KV

Erik, I don;t see this release under Index of /tinySA4/DFU The latest is tinySA4_v1.4-196-g1e9c187.bin Mike N2MS

Good day All. I'm trying to restore/align an old FRG7 Com-radio, have a TinySA that have been using as an RF sig gen and a Zeewiie DSO1151g scope that 'should' run past 100Mhz, well lets just say

Hi Juan, Erik added an 'abort' command? in V1.4165 (May2024) : /g/tinysa/topic/106071963#msg16704

Can you update the changelog please - it ends at 1.4-187 Thanks
