A 100MHz Handheld Oscilloscope for £54

We have never got enough toys in our cupboard. Dave Jones down at EEVblog always turns up with a few exciting bits of test equipment at times, that could be useful to our hobby. The FNIRSI-5012H that might be another good catch from one of his recent tech videos?

Sold as a Single channel 100MHz Scope for less than $80 with what does come with a few flaws, feebles and bugs, which makes it really a 20MHz workable unit. But it does go to show the Chinese are hot, and going places, where manufactures in the West would never enter a market for such a bargain price.





I did a bit of research afterwards and Banggood sell what appears to be the same model as the Dainu ADS5012H for less than £54 UK!! link here.

New excellent links added.

There are some very good Ham Blogs and websites out there if you are prepared to take the time to search them down.

One person that always inspires me with his enthusiasm for Real HF Mobile radio, is Dave G4AKC.








Dave often takes off to the front of Blackpool promenade, on either his bike, or his recent electric trike towing a trailer load of equipment behind him, that puts most shack's to shame. His late night shift on the cold sea front, or early mornings well wrapped up, quite often produces some long path and rare DX surprises that you wouldn't get from the home QTH, due to a good signal bounce off the sea water and the advantage of the lower noise floor being out in the open making reception far easier.

The G4AKC website https://www.g4akc.co.uk/  where you can learn more about his exploits has now been added to my Blog  right hand panel "Sites that do it for me links".

Another good Blog link EI7GL from Ireland has also been updated in "My Blog List" link again on the right hand panel.

The Antuino the new tool for radio amateurs from HF Signals, which I blogged about a few days ago.

Now it has it's own dedicated support group to help with problems, modifications and improvements, sign up here.


 

Mini VSWR indicator as reviewed by QST Sept 19

Steve Ford WB8IMY reviews the mini SWR indicator in this months QST. I do wonder when he purchased it, because they are at least $10 cheaper now on ebay?



What could be a handy little tool, but it pays to do your homework and research across all selling platforms before you open your wallet.

Check out this link for the lowest price I can see at the moment Here

The Antuino from HF Signals


HF Signals the small company in India headed by VU2ESE, that has recently brought us lots of fun with the BITX40 and the uBITX HF radio kits, has now done it again with the launch of the Antuino.

His headline for the device is: A compact Radio Lab for Antennas and Radio circuits.








I would like to think of it as a mini Radio Test Set that can help us understand what is going on up the antenna, as well as being a useful tool to help analyse what is happening within the radio or what problems exist within the RF signal it outputs. The plus of course it is hackable, so anyone can join in the fun and improve it with addons or make it's firmware better.

At $99 this is sure going to be another useful instrument to any Amateur's test equipment toolbox.

For a better understanding pop down to HF Signals:  http://www.hfsignals.com/index.php/antuino/





Still here!

Just a quicky from me to thank you all for your recent  best wishes you sent, some that reached me via email. The same problems still exist, but I am still around, and the Blog maybe quiet while I tackle the stranglehold, but I will be writing some more in the weeks or months to come or even later today, it will not become a dead ended Blog.



All the best to you all!

The SZ-70 cross needled SWR movement.

There is a twin SWR cross needled 100uA meter movement, doing the rounds from our friends in China . All you have to do is build a sense circuit and some passive electronics around it.




Who is the first to buy one and do a nice project feature:

From Banggood where I seen it first

Also various suppliers on ebay, but this is the cheapest I have seen from the cuckoo shop:

Have fun!!
