Thanks for those suggestions; I will implement those in my next revision.? Glad to see the empty grey buttons on those keypad entries instead of the transparent areas :-) I got my unit a few weeks

David Some suggestions for the menu chart * Go one level deeper on the two calibration menu entries * Use the data prompt text in the keypad as the large font title above the keypad. The helps to

david, thank you, congrads job well done, excellent.

OK, this sounds good. I now spent many days of work to optimize the correction table and calibrate it, because there has to be a bug in the correction function. Every time I reached the end of the

Klaus, If you created a custom correction table using your own measurement equipment, then you then you will always lose the table values if you do a "CLEAR CONFIG" or update to a firmware that clears

When you have measured and calculated your own correction tables you should keep those. If you did not do your own tables you should use the correction tables in the new FW -- For more info on the

Does it mean, that if I use my old correction values the get wrong measurements with the new firmware? -- Klaus, DL5KV

The calibration, or better called correction tables correct for frequency dependent deviations These are independent of what a calibration does. After a FW update the turns the ref level indicator red

Well done Erik!! 73 Jeff G8HUL

Erik, Can you describe the change in the correction tables? I don't know if it is necessary but I always un a CONFIG LEVEL CAL after upgrading firmware followed by a SELF TEST. Mike N2MS

A special thanks goes to Kurt as he did all the work for creating these updated correction tables. Without his attention for detail the performance of the tinySA would be much worse. -- For more info

I have downloaded this firmware but I don't recall any announcements for this version listing the changes. What are the enhancements and corrections? I keep a test file with all code changes. Thanks,

The delivered cables failed after about 1 week. The connector / cable interface at the shield came lose. I have since replaced them on both units with commercial RG223 cables of about the same length.

Hi Eric I have spotted a bug that seems to be in both original & ultra. with frequency entry set for Center and after doing a Marker to Center, the jog button will not change the Span either up or

I would hesitate to put a longer antenna on the tinysa or nanovna from a mechanical point of view - it will put a lot of strain on the sma and could ultimately break the connector from the pcb. Tim

It needs to be remembered that the whip part of the antenna, is only a part of the antenna. The other part is the case of the instrument and whatever else the case is "connected" to, i.e. it's the

Commercial cable manufacturer specification sheets often identify the minimum bend radius for the cable. ? ? In my professional experience, stranded conductor coaxial cables generally fall into to

See my quick NanoVNA screenshots, measured with the?tinaSA original antenna: minimal length (9 cm) maximal length (30 cm) For FM radio or 2m band I would take a longer antenna, or just order a long
