HF Frequencies
North America (red) Main activities take place on the 30 m band. No further information could be found so far concerning the other bands. According to WA8LMF the density of gates in North America is such high that digipeating is undesirable. A point of view that can be found in Europe as well. Anyway we have to keep on mind that i.e. mobile stations with a distance of 100-200 km to each other would never learn their proximity. With flat tires in the middle of nowhere digipeating then gets a different touch…
When RPR traffic starts now in North America a path APRS,WIDE1-1 is recommended. FSK (HFP) traffic does not encounter any influence by RPR ! Europe (orange) – see comment on previous page Africa (yellow) Only activities observed are on the 30 m band. It is known that RPR gates are offered as well. Whether that is upon request and therefore temporary only is matter of survey.
Oceania (green) – Driving force when it comes to HF-APRS are the Australian hams. Specifics here are the different frequencies on 20 m & 40 m compared to Europe and different side band selection as well. The historical developement doing HF-APRS came by the usage of old commercial radios. Those provided only USB and so 20 m was kept USB ever since. Shown RPR Frequencies are theoretical entries only for the time being but hams down there are highly interested to enter the community of robust packet users.
General statement about path setting in South Africa and Australia – In those areas gating to the internet takes place via crossgating to the VHF-net. So by using GATE and then WIDEN-n results in the nessecary hops to the VHF IGATE
