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

LETTER TO ARRL REGARDING CURRENT BOARD OF DIRECTOR ACTIVITIES

The following open letter to the ARRL Board of Directors and Leadership is in concert with many others coming from current members in response to the activities occurring at the ARRL Leadership level.

To join in and voice your thoughts, please visit:
myARRLvoice is an independent grassroots group of amateur radio operators working on behalf of our fellow Members of the American Radio Relay League (ARRL), monitoring the activity of its leadership and advocating change to optimize the organization’s effectiveness in matters of policy and governance, and to foster ethical and competent stewardship. myARRLvoice acts as a vehicle for ARRL Members to make their voices heard on matters of governance and policy, and to participate in the policy-setting process, holding our elected and appointed leaders accountable. We strive to make the activities of ARRL leadership more transparent by insisting on the creation and dissemination of records of the deliberations and actions of all ARRL Boards, Committees, and the operational Executive Team.
(More information is found after the following open letter)

 


To: All ARRL Directors and Officers

From: NW7US

Many actions–policy and governance–taken by the League’s leadership over the past two years trouble me. Formalization of specific actions planned for the Board meeting on January 19, 2018, specifically worries me.

At this time, any action taken by the ARRL Board of Directors cause me concern. As a result of this, I add my name to those seeking that the Board delay consideration of any ByLaw changes at the January 19 Board meeting.

In particular, I strongly urge you to:

1. Reject any proposal to allow the President and individual Vice-Presidents to vote as Directors.

2. Reject any provision that allows expulsion of an ARRL member “for cause” without delineated criteria.

3. Reject any provision that allows expulsion of any Director, Vice-Director of Officer for bringing ARRL into “disrepute” without specific criteria.

4. Reject any provision that reduces Members’ ability to recall a sitting Director.

5. Reject any current or proposed provision that allows the Board to disqualify candidates for elected office without full disclosure of the reasons for such disqualification.

6. Reject any proposal that would allow the Board to designate replacements for Directors instead of appointing an elected Vice Director or other elective processes.

7. Reject any current or proposed provision that allows censure, removal or other disciplines of a Director for revealing or openly discussing any view expressed at a Board meeting that is not consistent with the Board’s action.

8. Adopt a policy that elected Directors, and Vice Directors are not “personnel” for the purposes of declaring that any information about removal or disqualification is confidential and may not be released.

It is crucial that ARRL remain a solidly democratic, membership-based organization with principles of openness and accessibility through our elected Directors. I urge you to vote per my wishes at the January 19 meeting.

Beyond these issues of governance, I am concerned about the policy-making process of the ARRL leadership–leadership that I feel has become much less Member-driven, and that no longer reflects the needs of the Membership.

Ham radio is in a time of transition. The ARRL must focus on the issues that make a difference for the future success of the hobby.
