Tinysa wishlist


 

Dear all,

?I have been playing with both my SAA2 2.8” and my SAA2 3.2” screen vnas while waiting for my SAA2 with N connectors and its 4”screen.

I have been playing with my Tinysa too. ?I found that the small increase to 3.2” screen size on the vna made a big difference for (ancient) me both using the touch screen and viewing the results. I suspect my small screen vna may be given to the next needy friend.

The small increase in Tinysa case size to accomodate the 3.2” screen would surely be worth doing without any other change to the main board etc and might allow a bigger battery and possibly a (user-fitted) internal preamplifier (externally patchable when required) to either high or low input for greater sensitivity when chasing sources of qrm.

My other wishlist entry is a UHF Tinysa with 300mhz to 3ghz coverage.

Before we get a lot of replies of people all listing there wishlist I kindly request NOT to list these requests:

- A larger screen: This requirement is understood?and valid. IF there will be a next tinySA it probably will be a 4"
- Higher frequency range, preferably covering thill 3GHz. THis requirement is understood?but going till 3GHz with good performance AND low cost (sub 100$) will be EXTREMELY difficult. Yes, you can do an SDR type detector but getting good dynamic range combined with fast scanning and low cost is difficult. 3GHz will probably NOT be in the next tinySA (IF there will be a next tinySA). Some extension of the range may be possible.
- Lower smallest RBW. Yes, 2.4kHz is on the edge, 1kHz or even 100Hz would be nice. This requirement? is understood and IF there will be a next tinySA a step to smaller RBW MAY be possible
- LNA. A valid request. Making the internal 3.3V available to outside the enclosure and thus enabling the user adding a LNA (various amplifiers will work well on 3.3V) outside the enclosure and still be portable MAY be implemented IF there will be a next tinySA. There are in the current tinySA two connector holes at the edge of the PCB labeled with VDD. You can? use one of these to supply 3.3V for your pre-amp.

Do you find it interesting?
When selecting "FREQUENCY" => "CENTER":
If the frequency is below 350Mhz, TinySA selects "LOW in";
If the frequency is above 350Mhz, TinySA selects "HIGH in" automatically.
If that has already been answered, sorry :)
Using research in another language is sometimes a little more difficult.
Thank you for your work.
