I just got a TinySA Spectrum Analyzer. Let's figure it out together.

Any spectrum analzyers has a few basic functions:
* Set the FREQUENCY of interest
* Set the boundaries or SPAN you want to see to the left or right of your desired frequency
* Set the REFERENCE level that you want to visualize frequencies against
* Set the RBW or Resolution Bandwidth for how many inspection points there are instead of the SPAN you're looking at.

Good video, just got mine today, seems to check out and calibrate just fine. Now to chase down some RF hash around 13 mhz or so so I can start swling the HF Bands.

Nice! Have fun!

N6EF-Very timely video. I just received mine today from R&L Electronics.

@temporarilyoffline 2 года назад

Nice, make sure to pipe up over on TOADs, we can learn together.

Just ordered one because of this video from R&L. Watching the waveform from analyzing the FM broadcast band reminded me of the waves sent out by Gigantor's control box. Just picture Jimmy Sparks wiggling the controls at the low port and sending out that wave to control Gigantor. (Gotta be silly once in a while or things start getting too serious.)

I try to make it all fun too!

Just ordered one. Super useful for the price

Exactly!

I use a Malahit DSP2 with a Deshibo Ga800 loop. Have a tiny Belka too which is amazing. Still figuring out all the features on the Malahit. Going to be using the Tiny SA for things like highlighting transmissions on Airband etc. Still trying to figure out how, if possible, to set a low and high frequency on the Malahit DSP2 to do the same thing. The Tiny SA will do it in the interim. Any tips greatly appreciated 😊

@temporarilyoffline 2 месяца назад

I haven't played with a Malahit yet, but when I do, there will be some videos on it, for sure!

I'd love to see a demo on chasing down RFI with this tool. Every morning, when things are quiet on the bands, I see strong continuous signals that are about 75k apart. Quite strong on 20M.. These tools look quite capable..

@temporarilyoffline 2 года назад

I would too... I'm very fortunate to live in a small rural town without any RFI.

You're welcome Clarence!

@Kodo-Nashi 2 года назад

Very cool

@temporarilyoffline 2 года назад

I like it. I wonder if it could be used in fox hunting.

@janhenkins Год назад

Still an excellent video, Steve! :-) It's remarkable how the tinySA and NanoVNA devices are democratising proper testing. My favourite part of this video: 2:52 - 2:57

Thanks Jan!

I leave the screen protector on for as long as it'll stay, but this one has to go. Ordered mine early this morning, expecting it tomorrow.

@eyepointmusic1697 2 года назад

Do you think it is possible, to check the frequency of an operating HF-coil, to get another one into resonance with it?

@temporarilyoffline 2 года назад

Yes, I can see how you could compare the two coils and make adjustments using this as a measuring device.

@UpcomingJedi 2 месяца назад

You can test a BFO you just built for an old radio that has a fake bfo like the hallicrafters or none at all. Just in case it has similar signals or harmonics when the tuning cap is changed.

@temporarilyoffline 2 месяца назад

I want to do that one day. I'll remember your comment when I get to that project.

@dekelsani730 7 месяцев назад

This is with speaker?

@temporarilyoffline 7 месяцев назад

Nope

@Ibelieve218 Год назад

So if I hooked up a 4watt boafeng to the tinysa I would need a 36 dB attenuator

@temporarilyoffline Год назад

I'd go with 40, but yeah

@yungsmile7546 Месяц назад

That was you frying your tinySA when you keyed up😂😂😂

@temporarilyoffline Месяц назад

Been running fine all this time.

@atsmadane2575 2 месяца назад

Can the device pick up the frequency of 5 kHz?🎉

@temporarilyoffline 2 месяца назад

two inputs, high quality MF/HF/VHF input for 0.1MHZ-350MHz, lesser quality UHF input for 240MHz-960MHz - looks like it doesn't go that low.

@DennisSantos 11 месяцев назад

Why use the two leads with the gender connector when you can just connect one lead between the high and low ports?

@temporarilyoffline 11 месяцев назад

It depends on the type of test you are running. In this case, I wanted to equalize out the cable length. If you were only going to test one device on one port, the a one-wire calibration would be good.
