ZL DMR history

In Wellington we’ve been fortunate to have a DMR repeater on the world-wide DMR MARC network since August 23, 2011 where at 1930 the first contact was made with Bill N1EB. At that time there were about 60 repeaters in the network, today there are more than 300 machines in 22 countries.

Pending Update to WVHFG Website core software

Hi Folks

Some of you may have noticed the odd PHP error on the website (and for some time!)

Basically the website core software is due for an update, and though i've had the best intentions around doing so, I havn't managed it yet.

I wish to acknowledge this and let you know I do intend to do it (and hopefully sometime soon), so at some point in the near future will be a brief period of website downtime.

Apologies for the inconvenience - and for the transient errors in the interim.

Regards
Mark Foster ZL1VMF
Webmaster, Wellington VHF Group

Presidents Report WNVHF Group

Another year has gone by so quickly. Maybe it’s a sign of my increasing seniority… WNVHF Group has a wonderful committee that just gets things done, the only problem is, recognising how much work is getting done.

It is with some trepidation that we have Gavin standing down as Q-Bit editor after 7 years in the job. There will be a challenge to fill the shoes of a loyal and hardworking editor who made it seem easy by producing a quality journal month after month. I wish him well in his future endeavours.
