Ed, I'm sure Erik or Kurt will correct me if I'm wrong, but from the way the table values trend upwards at the high end of the frequency range, it looks like the "generic" values in dB are added to

Thanks, Herb! I will wait to see of anyone with experience chimes in before I attempt any edits. Am I correct in assuming that I need to increase the "generic" value in dB if I want the display value

Eric, I finally found the cause of the problem : The LNA was not oscillating but despite the 20dB attenuator it was still overloaded ! So I addad an extra 6dB attenuator and now I measure the

Ed, If you type the command "correction" with the Ultra connected via a serial terminal (tinySA-App, PuTTY, etc) you will get the following response: correction usage: correction

Herb, I do not recall seeing information on editing the correction tables in the Wiki...can you point me to some documentation on the procedure? -- Ed, K0KC k0kc@... http://k0kc.us/

Herb, Thanks for the idea! I will try to find time to do this later today or if not today, very soon. -- Ed, K0KC k0kc@... http://k0kc.us/

Thanks Erik for your response. No need to spend time on this. Just wondered if the behavior is known or not. I also thought that the arithmetic (unsigned char) overflow is worth mentioning...

The SPEEDUP command is a very low level setting added for ultimate speed increase when in FAST mode It has not yet been designed for ease of use so the behavior is weird The FAST and SPEEDUP work well

Any comment on this? Even though not very major...

How did you try to set the date? -- For more info on the tinySA go to https://tinysa.org/wiki/

There are currently no clones of the Ultra and all stores listed in "where to buy"? are safe to buy from -- For more info on the tinySA go to https://tinysa.org/wiki/

Hello one and all. Received my Tiny SA Ultra the other day and did a first use cal and everything worked fine. However, I noticed that the date is listed as 2020/12/04. I was able to set time with no

Pending any comments to the contrary, I am about to order some parts for for my TinySA Ultra(great machine, by the way, tnx! ) As179-92 switch BGA2817 LNA It is failing test #13 and getting an error

I did this to see how it works but I used a mini circuits VHF2700+ high pass filter. That suppresses the fundamental and doesn't cause overload if you have to increase the level because your harmonic

I've tested both versions: V1.4081,2 using from startup, center @ 433KHz, span @ 1.732MHz, shift frequency @ 0. They seem to do the same; positive side has 1 decimal point number, while negative side

Just compared the spec sheets and they are almost identical - even the ordering of the specs is the same.? Performance graphs have slight variation.? Digi-Key has stock and they ship overnight for a

Attached is a translation of the data sheet.? You can get 5 of them shipped to the USA by registered mail for $9 USD.?? If you want them quick FedEx or UPS is also available but costs much more.

Reading the FAQ: Under general questions the AS179-92LF is listed as the internal switch. Under tinySA Ultra questions input switch U22 is type number XA17-G4K. I cannot find a supplier for the

BTW, The generic level correction tables were based on the assumption that the manufacturing tolerance would be within ~+/-2dB for all devices and preproduction testing on a small sample of units was
