<div dir="ltr"><div>As there is no type acceptance requirements for the Amateur Service, pretty much anything goes as long as it meets the various requirements of frequency stability, spectral purity, modulation, output power, harmful interference, etc. Homebrew and modified commercial gear was the mainstay of ham radio forever.

<br>
FCC Equipment Authorization (formerly known as Type Acceptance) is specific about what radio services a product is certified for use on, although there have been some exceptions for amateur use.<br>
<br>
Just something to double check.<br>

Subject: [aprssig] APRS on 70CM using a hundred "free" UHF radios<br>

Apparently the Motorola VRM650 UHF data radio should be available for almost free by the hundreds.<br>
<br>
These are Motorola VRM650 modems which I think are a 40 Watt MCS2000 radio with a different faceplate and only a DB9 rs232 port.<br>
<br>
We need to figure out an APRS application and figure out how to use them.<br>
<br>
Apparently they are being forced out by FCC rules changes on the commercial bands.<br>
<br>
But we need someone that knows how they network together with data… AS-IS to see if we can use as is for some kind of Amateur Network.<br>
<br>
The first thing that comes to mind for me is to build the 2000 mile links along the Appalachians!<br>
<br>
We test the path every year in the GOlden Packet Event: <a href="http://aprs.org/at-golden-packet.html" rel="noreferrer" target="_blank">http://aprs.org/at-golden-packet.html</a><br>

Here is the link on the above page to our dreams for an East Coast backbone.<br>
