[aprssig] TM-D700A question

[Dave Baxter]

I think it is safe to say, anyone using any voice on the European
frequency of 144.800, will be seriously unpopular!  You are unlikely to
be heard at first in any case...

If as many say, your .390 frequency is also so busy already, having
people talking on there will only make matters very much worse, so I'd
guess the long knives would come out over there too..

For genuine "Emergency" working (such as in the wake of Katrina) or on a
"group net" frequency then there is maybe a use, but for normal APRS
use, and especialy anyone visiting the UK or Europe, don't use voice
allert, unless you want flames!...

In any case, it only works AFIK for users with the D700 rig...  D7's,
trackers, radio's and TNC's etc, wont open a new RX audio path.

Cheers..

Dave B.
