Compounding this problem is that we have no way of knowing if people are<br>
using the right symbol for their IGate. Are they using "I" because it is<br>
really a TX Igate, or just because it seems logical?<br>

"R&" Igates<br>
<br>
Maybe we need to have a 3rd symbol, a "T" Overlay so that operators of<br>
serious two-way IGates and indicate their dedicated intent to provide good<br>
APRS-IS local service. These guys will take the trouble to indicate a TX<br>
Igate. When we see one of those, we have proof-positive that the IGate<br>
includes a two-way TX capability.<br></blockquote><div><br><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small;display:inline">The new Rx IGates I've noticed are using the R& symbol, so at least they're indicating what they are.<br><br></div></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
We could even go one step farther. We could indicate the NUMBER OF HOPS<br>
that the IGate uses by default for IS-to-RF packets. This could help us<br>
better manage overlapping IGate coverage... So how about this plan:<br>
<br>
I& - is an IGate, but is ambiguous with respect to transmitting<br>
R& - means it is definitely an RX only IGate<br>
T& - Means it is definitely a TX IGate with one hop path only<br>
2& - means it is a TX igate clobbering two hops in all directions<br>
3& - means it is a TX SPAM GENERATOR , (or a legitimate special case)<br>
Etc..<br>
<br>
Should we do this???<br></blockquote><div><br><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">I haven't seen anyone using 2& or 3&, but I've seen a few that are using T&.</div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"></div></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

I'm bringing it up now because it was almost 5 years ago, and perhaps
there are several list members out there that were not on the list when
this was discussed previously - some of which could be new IGate operators.<br><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small;display:inline">Lee - K5DAT<br><br></div></div></div></div></div>
