BITX & uBITX resources added.



I have now added a Pages link to my blog titled

BITX & uBITX resources.


Access it from the top right handside of my Blog. 


This contains known links to groups, and support for the BITX and uBITX kits.

I will update links and details as and when I see new information appear, and of course when I have the time available.

If you know of any others please drop me a line below.


You can also access it via this link below too:

M328 LCR-T4 an updated version of M328 LCR Transistor tester.


I wrote about the original M328 Chinese kit sometime ago, which I had to build to prove to myself that VK3YE's capacitance offset error problem was a calibration error:

However there is now a newer pre built SMD version (M328 LCR-T4) which came into my hands recently, all that you have to do is kit it together with a prebuilt case  and a 9V battery NO SOLDERING: (Cost less than £8 inc case inc delivery).


This version has the advantage of being ready built with ZIF skt, and supports a better LCD full sized display!







I like this for it's ability to identify "any" transistor, or diode, you seem to throw at it.  Displaying the gain figures of, and whatever way around the device is plugged into the ZIF socket, it has the ability to identify the pin out configuration, and if it is PNP or NPN, or even a FET. so you do not have to keep getting the semiconductor book out or downloading the data sheet for the pin data.





I thought this version was so good! I got G4WIF of the GQRP club recently to include it into the new Tribal Knowledge - Test Equipment document here
