"PulseModem A" is an APRS client, that reads and reports APRS location and messages. APRS is a digital communications protocol that can exchanges information among large number of stations both local and global. You as a licensed Amateur Radio operators can send and receive APRS location and message in 2 ways: - Direct to the APRS-IS Network - Sent via amateur radios supporting VHF Band at 144MHz. Full AX.25 software AFSK modem is available for off-the-grid operations. Internet optional! APRS is a registered trademark of Bob Bruninga.
TX is ok, no RX messages when using RF
The TX functionality seems to work, other apps can decode the AX.25 generated by this app. However, “Pulsemodem A” does not show any decode messages while in RF mode! Attempted with microphone, line-in, and the input level isn’t distorting. I’m a 10-year licensed ham and media production engineer; all the obvious issues were tested. Off-grid functionality is not possible with this app without having both TX and RX!
Settings mislabelled, no location tracking..
The passcode and the host fields are swapped / mislabelled… so unless you know that or figure it out the app will not connect. Also, there’s no way to have location tracking, you have to manually transmit a packet each time. An ok start but needs a lot of work for practical use beyond occasional message updates or just browsing nearby transmissions.
Verify me?
Like the app, interface is fairly clean, instructions adequate. No mention of a verification method, but when I connect, a small pop up informs means that I am not verified and will not be able to transmit.
It’s a good start
Need to fix the APRS-IS password and server input boxes so that they’re correct (mine has the server input under “APRS-IS Password” and the password under “APRS-IS Server”. It would be nice to be able to select which port we connect to, but this is still a work in progress. Look forward to seeing how the software develops.
Need software update
There is a huge issue with the gps reading. Some time it send my location to the middle of the Atlantic Ocean close to antártica. My call sing CA3IMF. This is by RF aprs
RF aprs works BUT
First to all I want to say thanks to the creator for this app because Apple is always forgiving ham operators vs all the feature for android phones. This app need a little work in the audio output because in my case it’s going out throw the ear speaker instead the main speaker. So the audio is to low
It’s great!
Crossing my fingers one day apple will allow SPP Bluetooth connections! Works great for now through baofeng and wouxun radios!
Fixed display issue of the APRS passcode and APRS Host
