Trouble with these devices is the build quality, take it apart it's held together with hot glue and chewing gum, it also drifts on temp changes and the RF output stages die after a few months use, just have a look around online you will see so many ppl having issues, you will find the unit will still power on but over time the RF power will get weaker and weaker, it also has zero protection for accidental RF input so if you add much as even accidentally key up with anything over 1/4 watt with no attenuator you will blow the RF drivers.

A much better bet is to use the tiny sa as your signal generator because it's more accurate, will do both am and fm and you can offset your attenuator in the software, these meters are super old now, expensive, not accurate and unreliable.

Good review by you as always but this is a poor product, I thought this was ok 3 years ago when I reviewed it but it wasn't, I really wouldn't recommend this to your subscribers, the tiny sa is cheaper, works and isnt even primarily a sig gen but a spectrum analyser as well you would be mad to ignore it and use one of these, I would never connect one of these to any radio I cared about especially an ftdx10.

Happy New Year, I heard you on simplex the other day, your boiler had broken down, I hope it's now working it's not exactly warm, take care.

Hi Matt, i have it also and I love it, I use the signal generator *no FM modulation to test sensitivity on CW and SSB. Take care!

I have one that looks almost identical. It came with a warning not to exceed 12 v on the power input. The implication was that they had a number of returns as a result of people running them on their 13.8 v power supplies. I have found it to be good. Mine allows me to transmit into it as well, so not quite the same.

WOW! That Yeatsu You Have Is A TRUE DREAM OF MINE, WOW! Im Soo Glad That You Are Able To get Such Good Things In Your Life And Be Casual About It :)

Works a treat for me. Was surprising to discover my ancient Alinco DJF4-E is the most sensitive UHF handie I have by 4dB!

[WaynesWorld]

Great review as always. You are costing me a small fortune!

[andrewverran]

Positive points, low output not requiring further attenuation and output in dB !
Nice video.

Question - doesn't the Tiny SA have a signal generation mode? In your video on the Tiny SA, I think you used it exactly that way. Does this device do anything the Tiny SA doesn't do?

[Hi-Tech-Ray]

can I used this for the standard FM radio station band 88-108 MHz to align an FM radio receiver?

[cablemedic]

Put it in an spectrum analyzer and lol at its output.

On power up, there is a 490 MHZ spike even with the generator off.

[Capitaine.Albator]

Cool product. Now I have to understand why - db give s9 reception. So much things to understand 👍🏻✌🏻🇨🇦

[stefanStefan-elix]

how do you upgrade to a newer firmware version?

I have one, The Anttenuator blew within a few weeks, So not able to reduce the signal, It's ok for very very basic indication testing, But it's certainly not accurate enough for doing any valid measurements .

[realcomsolucoes]

I have one with input output with an internal dummy load for repeater and for radio power and frequency and tone ctcss tone decoder

[nativetexan]

That's funny. I always use my ears to test radio receive sensitivity. If I hear anything coming from the speaker, it works fine. If the sound is weak, the sensitivity is poor. If it is loud and clear, it is good.

Ali Express has become my replacement for ebay. That and the major banks will not allow most Americans to use ebay. The only item so far that was a disappointment was a device called an EvilCrowV2

[ardilla]

Better the UNI-T generator, not much money that this but you get a full generator

[zzxxenith]

A signal generator that's not accurate is completely useless no matter how cheap it is.

[Rockn-UV]

This looks like an inexpensive way to calibrate SDR dongles and devices.

[AlanScott-clor]

These are absolute rubbish. Have had 3 fail on me in a row. They are rubbish
