Episode 1325
New $120 spectrum analyzer 4" screen
100kHz to 800MHz frequency range and up to 6GHz in ULTRA mode
200Hz min. resolution bandwidth

Point of order: at 16:30 the HP would have 10 dB better NF if you removed the 10 dB of attenuation that is normally switched in. The SA Ultra apparently does not default (nor include in the specs) to any input attenuation when initialized, whereas the HP does. Fellow HP 8591E owner BTW. And thanks for the video too.

I’ve owned the original TinySA for a while, and in that time I’ve found it invaluable from a hobbyists point of view. I’ve preordered the Ultra primarily for its increased frequency range. I use a lot of 5GHz devices and to monitor them I’ve relied on my HackRF1 and a PC, this Ultra will permit a much simpler work flow, especially when out in remote locations.

@BigEars2011 @rickeaston3228 Gheesh people. The man spends his own money on equipment and his time on setting up and presenting this material without asking us for a dime and you have the gall to criticize him for not creating a professional quality presentation. If you want "Reality" TV slickness then break out your wallet and send the man some cash so he can hire script writers, directors, camera operators and such. Personally I prefer this unscripted first look over a professional presentation as the real part of reality comes through unfettered.

Thank you for the information one month before Christmas.
To try out my spectrum analyzer I bought cheap microwave motion detectors in the range of 5.8GHz, 10.525GHz and 24GHz which serve a simple sources and receivers. The motion detectors can be tuned (slightly) by the supply voltage and one of the the 24GHz modules even has an internal divider to measure the frequency with normal instruments at 3MHz. Together with LNBs receiving at 10GHz and using harmonics to reach their input range one can play around in the frequency range with tubes, resonators and shields. (Of course with limited power.)

Thx So much for doing this video !! Your review "Style" is perfect for folks like me learning how to use these New & complex affordable Rf test equipment....Your "How to Use" NanoVMA & this video are Immensely Helpful & vital for me so much so, I bought both !! Thx again & keep 'em coming !!

[sethlavinder]

Can’t hardly wait to get one of these! Awesome upgrades! I think I will greatly appreciate the bigger screen!

[chreinisch]

Holy cow, that stuff was around 100k in my radio workshop back then 35 Years ago 😁

[mariofilippi]

Your video was very helpful, I decided to buy one as a result. Tnx es 73's.

[thrillscience]

I've been waiting to pop on one. I was lukewarm on the original TInySA. Thanks for being the "guinea pig" for the rest of us.

16:07 noise is Bandwith dependent. It is not good comparison between 3MhZ and 850kHz.

[Halabaloosa]

It appears to have a better noise floor than the previous one, nice.

[raindropsrising]

Thanks for the honest review. Am getting one. Thank you.

[johnwest]

I just went and ordered one from R&L before this crowd watched the video and bought them out. :)

Just a short important notice. Whenever you connect the TinySA to a transceiver FIRST DISCONNECT the mike. I already toasted one's front end, accidentaly pushing the PTT with my belly, having the mike on my lap.

[JamesConway-sq]

This is the first I ever had but I found it very useful and as usual I watched your videos on using it, I don't know how long I have it, I thought it was longer than 8 months but maybe not anyway thanks for your videos and take care of yourself great work and Cheers... Jim. 😀👍

[qzorn]

nice TinySa-ultra video. 🥳 In setting setting up a DIY 21cm 1420 MHz SDR radio telescope dish this little analyzer was recommended. 🧐Now to figure out how to use it. Thank you.

[alklapaxida]

what a fantastic device thank you for showing it to uss
i must have one, as always...

[button-puncher]

Oh man, I can't wait. Thanks for the review. I loved the original but I wished it had a larger screen. Hopefully the tinySA MEGA has a HDMI out. :D

[PapasDino]

Ordered one from R&L; they had a initial 90 units that sold out so I'm in the queue for their next shipment.

neg 80 is getting close to the noise floor of roughly -120db. most decent recievers are right at home -30 -40, a good point to point ten years ago could run full modulation and passing ber test -26--32, our pathing boxes could pick up path at -110-12ish. just wanted to illiterate for the listeners anything below your rx threashold is two birds in the bush, above threashold and that birds in your hand
