Re: Persistent setting of Ext. Gain

 

Or "assume" makes an "ass" out of "U" and "Me"

Re: Attenuators

 

apart from an unwritten convention that the 'male' plug end is the source /high power end.?
Aha, but is that the male centre pin end, or the male thread end? This gender description always gets me!

Please use version V1.4170, available for all models, if you want persistent EXT GAIN

Re: Attenuators

 

?Bruce Akhurst?

When putting an attenuator on a TinySA, the /first/ attenuator in a chain of attenuators (including a chain of one) should be rated to handle the full power being sent to the TinySA, at the far end of the chain.??73RickKC3DO

?

As Rick says - also be aware most non-professional attenuators rated over 0.5W only have?one end that can handle the full printed rated power? ?

On some this is indicated by a stuck on arrow (with self-detach-over-time-function) while for others there is no clue apart from an unwritten convention that the 'male' plug end is the source /high power end.? ?(Except not always ???).?

On 2W and 5W? SMA attenuators the 'Male plug =high power end' rule generally applies and often if you get your best magnifying glass out you see?SU? (Which I read somewhere is Source/Upstream)? engraved on the outer 'Nut part' of the SMA male.? ?

Generally this will only bother you on the first attenuator as most are bi-directional once the level is less than 0.5W? (+27dBm) but its not a bad idea to consider it every time so it becomes automatic for when you are in a rush . .? ? ? (Also always check the pins on random SMA connectors before mating them is a pretty good rule to run with)

And I thought it was clear (to me?) but yes I mean ? for the larger screen 'ULTRA' and .
Re: Persistent setting of Ext. Gain

 

Are you talking about TinySA vs. TinySA Ultra??

The Ultra and "non-Ultra" most definitely take different firmware. See the TinySA docs for the details.?

Stating the obvious for some folks, but...

Re: Attenuators

 

I've purchased a lot of them on eBay. Enter "sma attenuator" in the search window. Since I do a lot of microwave construction and measurement, I have a whole set of attenuators that are good to 18 GHz.

Hopefully in the near future it will be possible. Thank you Ian for your answer. Erik makes a note on the "to do list", ...for when you have the time, Tank you.

Re: Persistent setting of Ext. Gain

 

Hi
Try version 169 for the larger screen or version 168 for the smaller screen, YMMV.
Re: Attenuators

 

AliExpress... maybe you get what you pay for.?

I got my attenuators from Dave's at W5SWL.COM - no problems, easy transaction, prompt shipment. Inventory varies, and it takes a little hunting to find the right parts, but they're there. Email asking about a couple of items was answered quickly.?

Re: QtTinySA PC Application v0.10.6

 

Hi Toni,

There is only SD_Read serial command.? It would need Erik to add a SD_Write command and advise how to use it safely before I could add that.

Re: QtTinySA PC Application v0.10.6

 

?Ian Jefferson? said:? Are there any 'desirable' features it has that QtTinySA is missing?

It is not a feature of the TinySA-App, but it would be nice if we could also upload files from the PC to the SD card, so we could upload configuration files, and test modifications and debugs the .CMD files without having to remove the card every time.

Yes I did see something in the change log, and so I upgraded to 1.4-166 but it still does not stick.
