Speaking of Radio Shack.. the verenerable HTX-202 HT can do seperate tones
for transmit and receive.. and that means it can do only receive, or only
transmit as well.

If it is the only thing in an area, no matter how small, then it should be
a full traceable WIDEn-N. Only make WIDE1-1's where there is the need for
fill-in digis in areas already satruated with wide coverage machines.
>...another digi down the highway a bit,...

DIGI's don't become WIDE2-1's, they have either traceable WIDEn-N support,
or are WIDE1-1 only digis. Again, souinds like this one should be also a
traceable WIDEn-N.
Great to hear you planting the seeds!

I don't think it is avaliable.
I assume it only has basic MYCALL and MYALIAS digipeating?
Then about the only thing it can do is WIDE1-1 and WIDE2-2 digipeating. In
a pinch, it can be used as follows:
Set MYCALL to WIDE1-1 and MYALIAS to WIDE2-2 and it will support the first
hop of just about everyone who is properly using the New-N paradigm. But
it will not bring in any second hops from out of area.
Or set MYALIAS to WIDE2-1 if many people in your area are using the mobile
path of WIDE1-1,WIDE2-1 and you will pick up their second hop and the
second hop of any fixed stations using WIDE2-2 paths.
Problem is if anyone else in the world is using this trick, they your digi
posits on FINDU will ping-pong. But that is a APRS-IS problem and not a
local RF problem. But the ham call in the beacon.

An entry level D-STAR radio costs about $330, which is about $60 more than
an entry level APRS radio.
When I claim that APRS over D-STAR is better than APRS over AX.25, I am
referring to the merits of the mode, not to the capabilities of a specific
model of radio.

That's what I assumed, but I haven't looked at the technical aspects of the
D-STAR, beyond "4800 baud".

The Yaesu FT-8800R has all of the above. It is exactly two radios with
completely separate memory banks. It does 800mhz and 900mhz too. No
trunking, but I do have the local trunked radio system in a memory bank
with all other local community support freqs and a hyper memory lets me
switch everything over to that, and activates just a handful of local HAM
repeaters on one side which we use for ARES activities.

This is a module which would be nice for Icom to sell, at cost to other
manufacturers to promote the growth of digital capabilities. We'll have a
lot more repeater and simplex freqs if we get 2M switched over to digital.
>-Two antenna diversity reception capability
That's a necessary need for digital operations on the boarder of range and
in multipath situations.

The FT-8800R has provided most of these non-D-Star features. It's a great
radio.

Maybe it will also digipeat on its MYNODE and MYBBS callsigns too? In that
case you could have four possible aliases. WIDE1-1, WIDE2-2, WIDE2-1 and
WIDE3-3 and the MYGATE call will digipeat across ports, though I am not
sure what that could be used for since the other port is 9600 baud.
Ah, you could make MYGATE be WIDE3-3 and then all 1200 baud WIDE3-3 packets
would get digipeated at 9600 baud on the other port so these could still be
monitored by the sysop on another frequency, but they would not add QRM on
the APRS channel if it was an N=2 area.
Just brainstorming... Bob

Ah, the WPD "wife proximity detector"...
Or even better, we can call it "GOTCA" - "Get Off The Couch Alert"
Now that is a great use for APRS! Good one, Bob!! :-)
