I was looking for some cheap spectrum analyzers and found these two:
- an Anritsu boat anchor for audio stuff: 10Hz - 30MHz
- an Anritsu portable one 100kHz - 3GHz

The boat anchor:


The portable one:


I need a cheap SA for doing some basic RF stuff (checking signals of transmitters etc.)
and this portable one looks nice. But I'm not really impressed about the specs. what do you think?

Regarding the audio boat anchor: there was this discussion about using soundcards for audio purposes,
but some people had the opinion, that a dedicated SA is much better than these soundcards.
So I thought it could be interesting for some folks here. No affiliations with the sellers.

What about these:


i also have an Ansitsu, but its big and it does not much more than the USB one, but it looks cool on the desk ;-)

This looks like a little nice device.
But my main complain about it is:
- Windows only software. at least I haven't found some Linux support

With a stand-alone device it doesn't matter which OS is running on your PC.
I have windows, but my main system to use is Linux.

Looks like generic CH341 UART. A couple of hours with wireshark and python and I reckon it'd have a Linux client  :-DD

Edit: looks like there is a linux source release of software as well but I can't find a working link: linnwt4_V4_11_10.tar.gz

There are times I wonder where your mind goes - let alone ask why it went there.....

... and I'm ever so glad to be left in the dark every now and then.  Like now.  :scared:

Wait... you're in the dark...? Ummm... is there creepy music playing, and does it smell like wet dog and frustration...?

If so... I'm sorry buddy; you're already in here with me.   :-[

What about those SDR dev kits we were talking about a while back...? They have *NIX support, and IIRC the software does a fairly decent SpecAn function as well as the nify color waterfalls. :-//

And doesn't the NanoVNA also do these functions with the more recent software...?

The pair of 6EW6 tubes showed up today and they are indeed brand spanking new RCA NOS.  :-+ It wouldn't surprise me if they have zero hours on them. Installed them in the Type 106 and already I'm seeing a difference in overall stability. Going to let them cook and stabilize for a few hours before attempting final calibration.  :-+ :-+

It shouldn't be a difficult fix. Tea isn't as corrosive as electrolyte or battery inards, the copper should be ok.

Quick question for you, on your Thurlby 1905a, did you ever update the input sockets for shrouded ones at all? I'm thinking about doing that but also slightly worried about the membrane panel getting damaged in the process of enlarging the 8mm holes to 12mm to accept the three sockets?

Nope, aside from a few age related marks and some dust, mine is as it left the factory.

I do hope you're talking about some bit of test equipment and not some part of your body.
Anybody got a syringe I can use to squeeze the magic smoke back into this?

€600 for a 8922x, Bit much methinks, even with the SA option. Take care when buying, they don't all have it. Addtionally the 'scope is audio only and the signal generator has no usable modulation capability. A 8924C, thats a different story.

A SDRplay SDR actually makes a usable spectrum analyser especially with the latest software.
