BOOK: Service Manual
New Zealand Wireless Set No ZC1 MkII

by Bernard Robbins

Options: An A4 sized comb-bound manual that will lie flat and is good in a workshop environment. 110 Pages.  Cost Including Shipping $35 An A5 sized bound book for convenient reference that fits in a standard bookcase. The A5 book has four, fold- out circuit diagrams. Total 164 pages. Cost including Shipping is $25

In this book Bernard reproduces the ZC1 service manual, which has been out of print for about 80 years. This book represents a primary source of technical information for those restoring the ZC1 MKIl. The original five Chapters is extended to ten by adding a significant amount of additional servicing information. Bernard provides a range of other useful circuit information including design enhancements and modifications developed by a range of amateur operators over the years.

This radio was produced by the New Zealand Government for use by the armed services during World War II. There are still many of these 80-year-old radios around, but finding supporting documentation today can be difficult.

Information is provided on a low cost, solid-state replacement for the vibrator. There is also a brief history of the ZC1 by Chris Underwood ZL2CU

BOOK: Random thoughts on Vintage Radio

by R.G Newlands ZL2AG

George Newlands ZL2AG

This book is a collection of previously published magazine articles contributed by George Newlands ZL2AG for the NZ Vintage Radio Society. Some of his writing has also been published worldwide and in the NZART Break In magazine.

Random Thoughts on Vintage Radio reflects his life-long fascination with servicing and restoring vintage radio receivers.

The book consists of 38 chapters (240 pages). It includes a diverse range of thoughts such as “Collecting –the disease we all share”, “Valve life and reliability”, “Servicing a Valve Chassis”, and “Disposal of a collection”, to name but a few.

There are numerous detailed technical notes accompanied with sketches and circuit diagrams written in his quirky and matter of fact style.

Recommended reading for vintage radio enthusiasts, or an ideal gift to someone you know who would appreciate a “real” book

BOOK: Amateur Radio Test Equipment

by Mike Woods ZL1AXG

This book provides an introduction to the range of test equipment that most operators will seek to acquire to further their interests in amateur radio. It covers essential equipment for general operating (such as an SWR meter and a multimeter), equipment needed for simple antenna experimentation (such as a nanoVNA) and equipment for construction of electronic and radio equipment (such as an oscilloscope or spectrum analyser).

In an age when test equipment has never been as easy to acquire and so inexpensive, there are nevertheless many traps for the beginner.

The book also provides guidance on how to purchase test equipment from China.

BOOK: Amateur Radio Magnetic Loop Antennas

by Bernard Robbins ZL2BD

KIT: Mag Loop Capacitor Starter Kit

This is a very easy to build variable capacitor with widely spaced plates. The configuration is a butterfly design, so that there are no sliding contacts to either side of the capacitor electrodes.

The capacitor stator plates are suspended on four M6 brass threaded rods. This makes direct connection to the ends of a robust loop conductor very practical. This very direct connection will keep the mag loop resistive losses to a minimum which is very important if building a transmitting loop.

The value of the capacitor in pico Farads (pF) can be adapted to a wide range of mag loop arrangements by adding or removing stator and rotor plates that are held on the threaded rods with M6 brass nuts.

The starter kit with 9 rotor plates and 20 stator plates will give a capacitance of about 12pF to 65pF and a voltage rating of 3.5kV.

Kit of Parts

Magnetic Loop Antenna Capacitor Kit of Parts

The starter kit is supplied with 5 threaded rods that are 90mm long to take the full complement of 9 rotor plates and 20 stator plates, using the supplied M6 nuts as spacers.

Different plate spacing can be achieved by doubling up the nuts, or using longer tubular spacers and longer threaded rods if higher voltage ratings are sought. This will also reduce the capacitance in pF per plate set.

Full instructions are available for assembly. These can be found on our support page.
