Hmmm. In USB-Data mode I can key the radio using DTR on

I was seeing three lines of text at one time. I think was in
USB-CW mode for that.
On most radios, the main difference between "USB" and "DATA-U" is
that the audio input/output is from the front panel on USB and a
rear-panel "data port" on "DATA-U".?? The receive tuning shouldn't
be any different.?? USB-CW is again normal USB receive,
but the input on transmit is the CW key jack, rather than
any kind of audio from a soundcard program.
I am transmitting these on the new APRS-overVARA channel
(10.148.200 USB) as WA8LMF-6 to give adopters something to receive
and verify that they are on the right frequency.
You are seeing one line of APRS Bulletin transmission, and three
lines of the KJ4ERJ space station object.??
APRS Bulletins are like APRS text messages, but addressed to
everyone (not a specific station).? They require no ACKs (since
they not sent to a specific station), and are repeated endlessly
until disabled.? (Normal messages addressed to a specific station
are repeated only a few time?if they receive no ACK, and then stop
.)?
Bulletins are typically used to announce weather alerts, upcoming
events, disaster info, etc.? Further, sending the same BLN # with
new content will cause the like-numbered bulletin line at receive
stations to be updated (overwritten) with the new content. ??
KJ4ERJ originates the space station objects every two minutes
showing the current location of the space station itself (an APRS
point object) and of it's radio footprint on the earth (APRS area
object). He inserts them into the APRS Internet System.? I fish
them out of the APRS-IS and re-transmit them over 30M RF.? [I am
assuming that if someone is far enough out in the boonies to be
using HF APRS rather than 2 meters, that they might also be
interested in knowing when the ISS and it's VHF digipeater is
overhead. ]?
Note that most APRS clients fail to decode and correctly display
APRS area objects though they will display the point object
directly under the ISS.? (UIview is one of the few APRS clients
that WILL properly decode and display area objects on it's maps.?
(You will periodically see the ISS "photo-bomb" my APRS screen
caps from UIview.)
I just got this in USB-CW:

Wrong year I think.
Apparently you are switching between the new channel and the old
channel.??
This is the old VARA-over-APRS channel (10.147.600 MHz). I have
been using bulletins here to? announce/talk? up the new
APRS-over-VARA frequency change to people still on the old VARA
channel.????? Yes there was a typo on the year -- now fixed.???
After Jan 1st, I will leave a "night light" beacon, from a second
transceiver,? on the old frequency for a couple of weeks
announcing that the APRS-over-VARA frequency has changed.?
Yes, I've had VARA in KISS mode throughout, though it
complains it isn't seeing anything on port 8300 it's connected
to pinpoint on the default of 8100.
The two primary VARA ports 8300 (Command) and 8301 (Data) are
used by WinLink, VARAchat and VarAC Chat.? They are NOT
used by APRS over VARA - the single port 8100 (KISS) handles
everything APRS-related.
??
2)?? Set the passband or DSP bandwidth tuning of the
radio to allow the bandpass of around 1000 Hz to 2000 Hz.?
(The VARA signal is about 500 Hz wide, centered on 1500
Hz.)
Depending on the nature of the slope of your passband
filter edges, you may be able to screw down the bandwidth
narrower. (Most filters start having phase shifts and
ringing at the passband edges, limiting how narrow you can
set the filters without mangling the complex multi-tone
VARA signal.)
3)??? Enable the KISS-over-IP function in VARA under
"Settings", "VARA Setup". Be sure to check the box "KISS
interface".? This becomes a TCP/IP server.?
4)??? Select KISS-over-IP as a TNC source in PinPoint.
This becomes a TCP/IP client connecting to VARA's server.?
Note that the IP PORT # in both programs must match.?
(Normally this will be the default VARA KISS-over-IP port
number of 8100.)?? The IP address of both programs will be
"localhost" a.k.a.? "127.0.0.1" meaning both the server
and the client are on the same machine.?
