<div dir="ltr"><div>Absolutely agree with you Bob.

<p>Keep in mind to also not run afoul with legislation. That might
seem to be about emergency use (UHF 5/35) or telemetry (UHF
22-23), but using simplex on the input frequencies of UHF
repeaters (31-38 & 71-78) that one is within the operational
range of is not allowed. Many contract roadwork gangs for example
use these and jam repeaters up.</p>
<p>There are also roadsigns out in country areas that suggest 5/35
for general information rather than the legislated "emergency use
only".<br>
</p>
<p>Suggesting one be careful creating features that specify these
channels.</p>

<div>Other than a one-off traffic_sign=*, is there a
relational way to advise which CB radio channel to use

<div>Interesting idea, Brendan!</div>

<div>I've often thought it would be a handy thing to have,
rather than just working on the standby of 18 / 40 for
caravans, + 29, but which then changes depending on the
highway you're travelling.</div>

<div>For example, Great Alpine Road advises users to

<div>As far as I can see, no, it hasn't?</div>

<div>I can find a few mentions of "radio" & such like, but
they're not what we're talking about here:</div>

<div>So lot's of negative results :-(</div>
<div><br>
</div>
<div>Maybe modify <a href="https://wiki.openstreetmap.org/wiki/Key:communication:radio" target="_blank">https://wiki.openstreetmap.org/wiki/Key:communication:radio</a>
so that it's not just talking about radio towers, but also
other types of radio comms?</div>
<div><br>
</div>
<div>then possibly have something like</div>
<div>communication:radio=CB + CB_channel=*, possibly attached
to the relation for the particular highway you're on?</div>
<div><br>

<div>Thanks
