Hi Crew,
I'm looking to hear success cases with using New Packet Radios (NRP).
Do you have good RF links using NRPs?
There's several flavors available now, including 2m, 70cm, and 23cm.
1) interested in anyone's experience with the Localino NPR for 23 cm.... how much, line-of-site does it require?
2) I have 70 cm units on the way. We have extensive 70 cm packet network, seems NPR on 70 cm would likely succeed. Your experience?
Here in Norfolk and Virginia Beach, terrain is flat with no mountains or high points (unless you have a personal connection with someone who can give you a spot on a high commercial building or tower.) And there's lots of tall trees to gobble up your signal. Thus, not having luck with devices that require true line of site.

I do not understand why this post is here in an AREDN forum.
There are no AREDN capable devices in 2m, nor 70cm, nor 23cm bands.

Several of us have AREDN nodes, but only connected via internet tunnels. NRP with 7 watts on 70 cm can provide the TCPIP link between nodes, where the higher frequencies/lower power cannot.
I have it working well with the 500mW units across my property.

Please express in meters, the distance 'across my property'.

Andre brought up NPR radios some 7 years ago as an addition to his AREDN network.

It would be interesting to try them in the situation like you have specified, I think it is call X-Links in AREDN
As i understand it as long as the link can talk IP it should work.
Of course the NPR link will be much lower bandwidth than an IP link or an AREDN RF link but depending on what you need to carry over it.

To put one on the air cost me about $80 for the radio, $140 for the special UHF amp and $60 or so for a 6 element yagi. Then the coax and other miscellaneous parts plus the time to install everything on my tower. The link was some 8 miles and worked rather well, with streaming video.
Then someone read the FCC rules, and data isn't allowed the same bandwidth as video. So the developer created another speed/bandwidth to comply with our antiquated FCC rules.
It was fun, but not practical in my view. Oh.. I have a box with 3 complete radios, amps, special connectors, etc, etc... Probably take them to the Blind Center here in Las Vegas for recycling.

"You have clouded the issue by introducing facts, logic, and reason." Too many authors to determine who is on first.
Hi, Richard:
I think you fully answered Carl's query.
I lightly scanned ?all? the Forum posts that contained 'NPR'...and there were many 6-7 years old. ;-)
I think you fully answered the unanswered queries from those posts, too. :-)
So, Carl and I are still seeking success cases of
