March Main Meeting (Online) - Jojn ZL2 XJ on Mesh Optimisations

By ZL2WAL on Fri, 03/25/2022 - 11:56

This month’s meeting is an update on the work being done by the Wellington mesh steering group. The group has put together a plan to reactivate and enhance the various nodes around Wellington with the aim of making it reliable and a valuable asset for remote operations and AREC use. There are mesh nodes on many of the VHF Group’s sites and members’ homes, so it will be good to have them working again.

John ZL2TAU Silent Key

By ZL2WAL on Mon, 11/29/2021 - 12:29

Sadly we hear that John ZL2TAU (Salvin John) passed away over the weekend.  We offer our sincere condolences to John's partner and his family.

John had just made it to 80 years and had been an amateur since his early 20's, certainly a double old-timer.  John was very active in radio both professionally and as an active amateur.  John has been involved in construction, repeaters, VHF DX, and site investigations and negotiations over the years, and was a very strong supporter of the VHF Group.

A couple of recommended DMR radios..

By ZL2HD on Fri, 11/26/2021 - 12:33

I asked for some recommendations of a good radio to buy at the November meeting.  

A couple of radios were recommended by people who had very recently been studying this subject and had purchased these radios.

Thanks for sharing your experiences.

 

The RT73 mobile dual band DMR was recommended. Very small, powerful, very good. It was noted that this radio could hold all the DMR IDs in the world, so every contact came up with callsign and location.  Some rave reviews on AliExpress and some tips to follow.
