Hello all,
I don't like the idea of regulatory discussions on this list.
However, I am curious (as it's pertinent to what we do on this list)
what the rules are in other counties for ham radio.. So far I haven't
had much luck finding the answers on the web.
Presently in US ham radio data bandwith:
2 meters is 20 khz max, 19.6 kilobauds
70 cm is 100 khz max, 56 kilobauds
Ironically, while there is plenty of space on 70 cm, other modes like
ATV are permitted to occupy up to 6 MHz of bandwidth.
Since we have a nice mix of hams from all over the world on this list,
I'd appreciated a reply (can be off list) on what is permitted in your
country on 2 meters and 70 cm.
Thanks,
Steve, KB9MWR

In the Netherlands, if it fits in the bandlimits you can legaly use it
regardless of mode, band or speeds.
Offcourse you have to wonder if it is smart to use a small band like 2
meter (2 MHz wide) with very wide modes.

A question...is it really limited in bandwidth to 19.6K on 2m and 56K on
440 or is it just that this is the maximum used by the modes in common use?
While at Data Radio (now calamp) we had 56K on a standard 20KHz channel
for Police/Fire and Utilities. Their Viper Radio claims 32kbps on a
12.5khz channel. (as you know there are no more 20khz freq for commercial)

For 160m to 15m: 8kHz
For 10m: 16kHz
For 6m & 2m: 100kHz
For 70cm and up: unlimited

New subject: Amprnet Gateway and Dynamic DNS.
Hi all,
I've just got back to experimenting with IP over ax.25 after many years.
I've got rip44d running on my Raspberry PI, and my gateway registered on the
portal. My ISP doesn't supply static IP addresses, so I'm using no-ip for
dynamic DNS.
I'm planning to add support for the gateway to my BPQ32/LinBPQ ax.25 node
software, but after searching the web, I can't find any info on how the
Amprnet Gateway handles dynamic dns.
So I have a few questions. Can anyone help with the answers?
Does the gateway re-resolve each hostname before sending out each rip44
update? Or is the name just resolved to an address when it is added to the
portal?
Is there any mechanism for uses to send RIP messages back to the gateway
when their addresses change?
Is it possible to get a version of encap.txt that lists hoatnames instead of
IP addresses, so uses can resolve them themselves?
Thanks,
John G8BPQ

with Net44 you have a static IP directly, no need dyndns is well
you can write the ip 44.xx.xx.xx in setting DYNDNS!

The hostnames provided on the portal for your gateway is updated once

LinBPQ handles 44-net fine as it is now with the exception of how it
handles ARP from what I see. Windows however is a totally different
story all it's own. There is no native ip protocol 4 support in windows.
XRouter/XR32 claim to handle it, but I have yet to see it work properly.
You may want to consider a pseudo nic for Windows for ipencap (similar
to linux's tunl0 interface) to handle this. It may also be a can of
worms you may not want to open.
Does the gateway re-resolve each hostname before
sending out each rip44
update? Or is the name just resolved to an address when it is added to the
portal?
I believe hourly, however Chris and/or Brian Kantor can verify.
Is there any mechanism for uses to send RIP messages
back to the gateway
when their addresses change?
When the gateway is configured properly in the portal, there's no need
to send RIP back. The portal will do the hostname resolutions prior to
building a new encap.txt and rip table.
Is it possible to get a version of encap.txt that
lists hoatnames instead of
IP addresses, so uses can resolve them themselves?
If there's a need for users to resolve dynamic commerical IPs
themselves, then something is wrong with the user's config. Just like
with a phone, internet routes via a series of numbers. A hostname is for
human-use moreso than for routing. If we were to eliminate DNS online, i
don't think ampr.org would have any routing but 44/8 does.

Hi John ,
Looooooong time no speak!
I use a cname entry. My g7ltt.ampr.org name is cnamed to g7ltt.dyndns.org.
The upshot is that the station trying to connect to me does the DNS
chasedown rather than the ampr.org server. I only ever need to update the
gateway server once and let my firewall take care of dyndns.
This works with MX records too (heard from g1plt lately? ).

Mark,
I'm interested in your statement regarding CNAMES and MX records because I
tried a couple of configs that didn't work. Then I remembered that RFC 1912
(section 2.4) specifically disallows the use of CNAMES in combination with
other records, like MX. Also, I see no entry in DNS for g7ltt.dyndns.org.
Instead, it looks like the CNAME for g7ltt.ampr.org is ni2o.ampr.org.
So can you be more specific? For example, what is your situation and what
entries did you make in DNS to solve it?
Thanks,
Michael
