  • A Note to Members from ARRL President Rick Roderick, K5UR

    In the last few weeks, the ARRL’s Board of Directors has been the subject of an organized misinformation campaign. It is being orchestrated by a group of hams, some of whom are well-intentioned but have been misled. This effort, which consists of a series of mischaracterizations, initially dealt with (1) the ARRL Board’s censure of an ARRL Director, and (2) some proposed revisions to ARRL’s Art...

  • 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
