VHF/UHF DX Book Replica Edition

/

'The VHF/UHF DX Book' was written in the early to mid-1990s by a team of experienced VHF/UHF DXers and equipment developers, in an effort to pass on our knowledge and stimulate further developments.

But eventually the book went out of print, and information of lasting value became trapped on the printed pages.

To keep that information alive for future generations of VHF/UHF DXers, a digital replica of the Second Printing (1995) has now been released as a free download, by kind permission of the copyright owner TR Publishing and its proprietor Trevor Preece.

As with all older books, the challenge for the reader is to separate the parts that are of lasting value from other parts that have become dated. But we make no apology for that; even the outdated parts remain an accurate snapshot of VHF/UHF DXing in its heyday.

ACMA Reverses CB Decision

/

The Australian Communications and Media Authority (ACMA) has reversed its decision to make 40 channel UHF CB radios illegal from June 2017 

It is estimated there are thousands of UHF, or citizens band (CB) radios on farms and in trucks, caravans and businesses throughout Australia. Upgrading to 80 channel radios was going to cost some businesses tens of thousands of dollars.

The manager of spectrum licensing policy at ACMA, Dominic Byrne, said the two systems are working well alongside each other so the authority had decided to remove the requirement to upgrade to 80 channel UHF sets.

“These changes were introduced to manage congestion and interference in the CB radio channels.”

Truck drivers around the country were taken by surprise by the original decision to make the 40 channel radios illegal, according to Rod Hannifey from Dubbo in NSW.
