Is there an APRS Freq in 440 70cm in the USA or other countrys?

Hello Vince,

Generally speaking.. No, there isn't really any "national" APRS frequencies in the 70cm band.? Per :

?? - United States uses 144.390
?? - Europe uses 144.800
?? - Australia uses 145.175


That said..? different regions can and will have their own specific bandplans so you need to look things up for your your area.? For example, in my region, there is one secondary 2m APRS frequency:

??


For your region, the best I could find for Idaho is this:

??

but it doesn't look like a real band plan and there isn't much mention of 70cm or any other frequencies.? You might want to email some of those resources to learn more.

Just adding to what David has provided, the WIA (Wireless Institute of Australia) 70cm band plan (at 09-2020) shows 439.100MHz as the Oz national ARPS frequency.

Could 9600 baud be used on a 70 cm Freq? I don't have my book handy to look. thanks

In practice? NOPE! In theory, it has been discussed a few times. Even by the author and many others. However it has not caught on. There are many areas that 2 meters is just too congested and 70cm makes sense.

Sincerely,

?Mr. Chris A. Robinson?

Possible oops, my previous might be interpreted as the 70cm frequency is "it".? To clarify, for just in case, Oz does also have 145.175MHz as the 2m national APRS frequency.

For APRS?? Definitely 145.175. I can only guess that there is some use being made of the 70cm frequency "somewhere" in Oz but I'm rural, around 350km from the nearest city major city, where there's not much 2m APRS activity apart from the occasional mobile passing through, or numerous digis "talking" to each other. There's no 70cm APRS around here :) My APRS efforts these days are directed at providing VHF and UHF satgate facilities.

To put things into perspective for channel usage, there is only about 15,000 licensed hams in Oz, a country roughly the size of the lower 48 US states but with a population of only about 27,000,000.

In California there are voice repeaters on this frequency.? Many have been on 442.925 for 30+ years, so check before using for APRS.
I wish there was a 440 frequency as well, so don't think I'm trying to hog the 440 band...
