Nice video, but I don't think the TX-500 is making any power. Look at 2:59 when you go key down. The power graph on the TX500 isn't moving, so no output. What you are seeing is carrier leakage at -56dBm. Put the TX-500 in RTTY and then hit the mic PTT or put a straight key on the rig and go key down. if the Radio is making 10W CW, then the math is +40dBm (10W output power) Minus the attenuator -40dB = 0dBm is what you should see on the TinySA or the Siglent for the fundamental tone. Great video concept, you just need the radio to make some power for the test. de KB7ZUT
That was a good find and it wonder is the filter is less at the frequency you were seeing. The other issue is how close the spur is to the fundamental. This is really interesting, Thank you for the video.
@@TheSmokinApe but I learned a lot about dirty harmonics from your video which is cool. And Sherwood did say the tx500 was too dirty to amp without using a quality amp
Did you set any attenuation on the TinySA? Eg manual -20db ? Fyi I have a tinySA and bought the same 10w 40db attenuator after watching your previous test video. I want to test my g90 (@10w or less) and my UV-5R but don't want to damage the TinySA
That level looks wrong... If its 10w (+40 dBm) and a 40 dB attenuator, then the fundamental should be around 0 dBm on the TinySA. It looked to be -50 dBm.. faulty cable, attenuator? Or is it just me?
@@TheSmokinApe Not necessarily.. If the TX599 is not transmitting carrier, then could be viewing the carrier suppression. You should see 0 dBm on either spec an
@@technishn so when at 3:20 you see the noise floor lower than -90db and I key up and the signal is at ~-53db or a 40db signal that’s not enough to convince you that there is a signal?
@@TheSmokinApe The TX should give 0 dBm after the attenuator. You are seeing a much smaller fundamental signal. Can you test with a handheld or another QRP HF TX?
really? Do you analyze a professional and certified equipment for sale, with a Chinese analyzer of known inaccuracy and admitted use, for amateurs...? You are not rigorous.
@@TheSmokinApe I don't use Siglent for any RF measurements (only as digital oscilloscope and logic analyzer). It reminds me of a case that happened many years ago when I bought a new spectrum analyzer of the similar level from USA with a phase noise measurement function for my home lab and for a long time could not understand why my UHF synthesizers were not getting better ... :-) Well, I checked your measurements with another source and they are roughly the same. However, the measured parameters correspond to TX500 specifications. Keep in mind that this is a portable 10W QRP transceiver and connecting a 10kW PA would not be a good idea.

You are correct, thanks for the call out. You can see an update here: th-cam.com/video/sDCibaKktAA/w-d-xo.html
@@TheSmokinApe Cool. I will check it out.
Wow, TinySA!! I’m impressed. What a helpful video. I wonder what the x6100 would look like on there… thanks for killer content. As always.
Hey Backcountry, glad it was helpful. Thanks for watching!

Glad you liked it Thuff, thanks for checking it out!
Great video Ape, I need to play with the tiny sa more and get more familiar with it!
Thanks Chuck!
Great video man.
Hey thats a nice SA ya got there.
Thanks man, just finished a follow up to it....
@@TheSmokinApe I'll have to check it out.
Ape, that’s a defective Lab599. Feel free to mail it to Tampa so you don’t have to be burdened with it. Nice job as always.
Haha, thanks for checking it out HOA!
Love my TX-500. Sherwood reports already ran the rest
Test 😂
Lol, Sherwood is the man…

What is that red line?
It the real time metric, when you put it in Harmonics the yellow line is the average four sweeps.
What's your thoughts on a first VNA? For VHF, UHF and HF. I have a NanoVNA-H on it's way but considered this TinySA. There are so many options...
Think i just realized this is not an VNA?
No sir, but for the VNA I like the H4: www.amazon.com/dp/B083PQ4RXZ/?ref=idea_lv_dp_ov_d

Fyi I have a tinySA and bought the same 10w 40db attenuator after watching your previous test video. I want to test my g90 (@10w or less) and my UV-5R but don't want to damage the TinySA
I had the attenuation set to auto on the TinySA. I wanted to test my g90 but just traded it before I had the chance! Thanks for watching Michael 👍
Can you link to the attenuator you used? Thanks.

So, we will post power output tests. That said, independent of power output, the second signal is there... would you agree?

You damn right about that 🍻
I need another Smoking Ape tee shirt. I get a lot of compliments on it. Will they make a comeback?

I almost panicked.
lol
Are you sure that TinySA is a real measure equipment to make any conclusions?
You did see consistency with the Siglent correct?
