Lynn,

That makes sense ... I think I noticed the errors after I entered the
password to unlock the screen saver after it had been idle for a while.

Thanks,

That error occurs when the program cannot access the display. I'm guessing that you're on a laptop? It happens to me when I close the lid or suspend/resume the machine. The program actually tries to update the screen before the video card has re-initialized.

I removed that popup when the error matches the one generated by that situation. Hopefully I'll get some time later this week to polish up the configuration of the KISS TNC and NMEA GPS support so I can get the next release out the door.

Re: Sending a message to a group - spec!

Lynn Deffenbaugh
 

Ok, I thought about this some more and remembered something about message groups which was sort of mixed up with private nets in my mind. I went back to the aprs101.pdf spec and found the following on page 72:

Message Groups:
An APRS receiving station can specify special Message Groups, containing lists of callsigns that the station will read messages from (in addition to messages addressed to itself). Such Message Groups are defined internally by the user at the receiving station, and are used to filter received message traffic.

The receiving station will read all messages with the Addressee field set to ALL, QST or CQ. The receiving station will only acknowledge messages addressed to itself, and not any messages received which were addressed to any group callsign.

Note: The receiving station will acknowledge all messages addressed to
itself, even if it is operating in an Alternate Net (see Chapter 4: APRS Data in the AX.25 Destination and Source Address Fields).

If I read this correctly, I would need to add "additional received message" callsigns which will cause any received messages for any of those callsigns to be displayed. I've also read that the Kenwood radios automatically display any messages addressed to the base callsign regardless of SSID for your own call. Finally, it seems that ALL, QST, and CQ are always on the "additional received message" callsign list.

I'll add this to the ToDo list and see what I can do when I get around to beefing up the received message and bulletin section of the client.

Lynn (D) - KJ4ERJ

The only "group" APRS messaging feature that I'm aware of is via the
CQSRVR. If you and everyone else send a message to the CQSRVR with an
agreed-up group ID, every subsequent message sent to that group will be
sent to all members. However, CQSRVR does have a minimum time limit for
any single message sender to the group.

See CQSRVR documentation at:

http://www.aprs-is.net/CQSrvr.aspx

Maybe there's another "group messaging" feature in the Kenwood firmware
or UI-View, but I'm not currently aware of it and haven't noticed it in
any of the APRS specs that I've read.

For example it appears people can choose to receive NWS messages. But I can't find any information on how to do it. Is my recollection correct, and if so how do I go about it? And is anything special needed to originate a message to the group as distinct from receiving it?

Re: Disabling GPS

warpedspeed
 

Lynn, this topic just answered the question that I was going to ask about, no position Tx without GPS data.

I installed APRSISCE on my old T-Mobile MDA (HTC Wizard 200) last week, and it is cool stuff. However, this phone does not have a GPS. I have been manually putting my posit in the XML file, but noticed that my "little phone" was not making it to the 'net via the IS servers. I can still Tx and Rx messages, so there is happiness there, but I am effectively in stealth mode. This is a great solution for days like today, when I am in the office, and my position will not change. When I leave the office later this afternoon, I will turn off APRSISCE, and a few minutes later my mobile symbol will appear on the map.

Installation of APRS software, and using the WAN at work to connect to APRS-IS would be violations of agency policy where I work. I know this, since I am one of the guys that enforces these policies. So being on APRS at work with a PC is not an option.

This is a great product that allows me to keep a pulse on APRS, while still doing my job.

I agree that it would be a great feature to be able to beacon without GPS. Of course you would have to add a time interval setting.

Thanks for your efforts on this Lynn.

You're welcome. It's like the folks at Google say, "I eat my own dog

long enough period of time. The UI-View replacement when I heard a rash

View/Buddies is the beginnings of the ability to see when one of your

ToDo list to make Buddie maintenance more straightforward, but for now
it figures out buddies based on scanning the Additional Filter string.
Just add elements like the following to define "Buddies".

b/KJ4DXK* b/KJ4ERJ* b/KJ4OVQ*

This will cause the scrolling station list to reverse-video any station
starting with that callsign as well as mark that station as a "Buddie"
for the View/Buddies display filter. When I get to the Buddie item on
the ToDo list, there'll be a separate configuration list of station
prefixes to define explicitly as Buddies and APRSISCE/32 will
automatically create the filter string.

I wonder if disabling GPS and disabling beaconing ought to be separate functions? If I carry the phone in my pocket around the house disabling GPS is useful, not just because it can't get an accurate position, but to save the battery. But I still want to have APRSISCE running because I want to receive APRS messages. If you've seen my blog recently you'll see that I am implementing the ability to receive alerts of WOTA summit activations by APRS message.

Following your advice on my blog yesterday I have disabled the GPS after fixing my position while my HTC is sitting in its desktop docking station and not moving, to prevent the problem of my position scooting off at high speed due to variable indoor reception.

Hum, that is a potential problem, isn't it? As I mentioned in the Blog, I toggle the GPS off when I go indoors to prevent the drifting caused by decreased satellite coverage, and mainly the "locked on one satellite and won't let go" 10s and 100s of mile drifts seen in my AT&T Tilt's GPS (same as an HTC TyTN II).

But you are correct, when the GPS is disabled, position beaconing is also suspended in the APRSISCE/32.....I was actually planning to add Status beacons (> datatype) to the client, I wonder if aprs.is would consider that "active" with respect to the timestamp. Maybe I'll just rethink the interaction between Enables/GPS and Enables/Tracking. It would seem that maybe Enables/Tracking should continue to send your most recent coordinate even if you disable the GPS, at least for as long as the client is still running.....

Consider it added to the ToDo list! Thanks for the observation and suggestion!

Re: Metric units

Lynn Deffenbaugh
 

I have a metric option on my ToDo list already. One of the interesting features of APRS, however, is the ambiguity in the transmission of Altitude (at least, I think it's that one). It may be in meters or feed with nothing to tell you which it might be. However, the majority of the stations seem to be consistent with it, which is, I guess, better than nothting.

Re: Feedback solicitation

g4hyg <chrism@...>
 

Hi Lynn,

I've just downloaded the Windows PC version and it's working well.

One observation when using it for the first time was that I "lost" the map trying to zoom in and I had to edit my location in the XML file so that it would display again. It appears I had ended up with my position at the North Pole!

Other than that minor starting glitch the program is excellent and is well on the way to being a UI-View replacement! The messaging works well.

FYI I'm also developing an APRS program APRS Messenger for serial TNC's and APRS over HF PSK-63 so I appreciate the amount of work it's taken you to get it to this stage!

73,

Chris, G4HYG

I ordered a docking station for my HTC Touch Pro to keep the battery charged and hold the phone conveniently where I can see the APRSISCE screen. This docking station has two connectors, one for 5V DC for charging, and the other a USB connector for syncing with the PC.

The shack computer was off and I noticed that when the USB connector is plugged in to the computer and the charger is powered on, the lights on my USB PC keyboard are illuminated! I can see what is happening - the 5V power is going via the USB cable to the other USB devices. I'm not sure that this is healthy.

If anyone else has a similar docking station I'd be interested to know if this behavior is normal, or whether it is potentially harmful to the PC.
