How

you say, not they do not send an acknowledgement, but how is
this any different to there not being a station there?

I
may, of course, be missing something obvious, but my
understanding is that a receive-only igate is exactly that: it
gates what it receives to APRS-IS, and transmits nothing, so I
don't see how it has any effect on the RF channel, or does not
allow messaging to another station to work.?

?Messages DO involve an ACK.??? If the sending end doesn't get an
ACK because the igate is one-way, it just keeps trying over and
over until it finally give up. This can take minutes or even
hours.
