[OZAPRS] 40m gates

[Warren_Brown]

Hi Mathew,

 

There is plenty of CW above 7020, and now with the new band plan you will often hear CW on 7050 which has become a VK/ZL calling frequency.

The SOTA activators now tend to use 7032 rather than 7028 and will go either way should there be more than one station on.

 

Regardless of the likely hood of being heard by an EU or W gateway it would be nice to minimise the footprint taken up with APRS.

Hi Gerard,

 

I've queried the WIA decision makers and TAC (both state and federal) and will wait for a response.  It will help to understand where the WIA is coming from in any frequency change decision etc.  I'm fairly confident your right about the Region 1/2 harmonisation... however haven't seen much CW over 7020 unless there is a special event station there somewhere.

 

I guess it will ultimately be up to the operators of the Gates to decide where they put their transceivers.  I also remember how passionate Larry VK5LY was about his 40m gate (*grin*).

 

Of an afternoon on 40m I hear a great deal of SSB nets between 7040 and 7060 here from VK5, every 5kHz is typical.   A few of these nets have been there for years, so having someone come up on them will always result in some angst.

 

A good question on harmonisation, don't know google foo required.  It makes sense to limit this to VK/ZL and the surrounding areas.  Not sure who or what "surrounding areas" means just yet.

 

Probably a good idea to see what information comes back from the WIA and just simply sit tight for the time being.

Hi Matthew,

That is the bandplan for ITU Region 3 (our region) and as you say it has narrowband modes from 7030 to 7040 unlike the WIA bandplan that has CW within this segment. It would be worth clarifying this with the WIA TAC (Technical Advisory Committee). I expect they'll say it is for harmonisation with IARU Region 1 <http://www.iaru-r1.org/index.php/documents/Documents/HF/IARU-Region-1-HF-Bandplan--2014/>  and Region 2 <http://www.iaru-r2.org/documents/explorer/files/Plan%20de%20bandas%20%7C%20Band-plan/R2%20Band%20Plan%202013.pdf>  that have CW up to 7040 then narrowband digital modes from 7040 to 7050 then wideband digital modes (and SSB) from 7050 to 7060.

As for increasing awareness of the frequency change, promotion on this mailing list, WIA broadcasts as well as the outlets you mention would go a long way towards saturation coverage. Advising users of the 7040-7050 segment about the change in mode will be a step towards seeing it freed for digital modes. I know of one daily net that has already moved from 7045 to a frequency in the SSB segment. There are more - it just takes time.

Considering our new bandplan, are there other 40m APRS users around the world that we could harmonise with?

Cheers,
