## PulseModem A Reviews in United States

### ***** "Intuitive"
Intuitive and fun
-- Honu Surfer, 2025-10-18

### ***** "最大的优点是免费"
正如标题所说的那样，这款软件最大的优点是免费。
-- BG1FPX, 2025-03-15

### **--- "Meh"
TCP/IP works fine. However the RF modem being the lackluster flagship feature stinks. TX works great but RX doesn’t.
-- llamaking136, 2024-10-11

### ***** "Perfect for APRS!"
This app is great for when you need aprs in a pinch. I've used this app for a few years now and had great success. You don't need an expensive bluetooth TNC, you just need your radio and your iPhone. Hold your radio microphone to the upper speaker on your iPhone and hit transmit and you're set. Perfect for what I wanted. Thanks!
-- quotok, 2024-09-13

### ****- "Good"
Not a bad app but I dumped it for one that will beacon.  If this one beacons I wasnt able to find out how to find that option.  I prefer one that will beacon my location at intervals VS me having to tap a green bar every 10 minutes.

But other than that the app was decent.  Seemed to work as promised.
-- Hdhfurecfehcefjcefjcef, 2024-04-26

### **--- "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!
-- The Asset 006, 2024-02-10

### **--- "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.
-- Jaedendak, 2023-05-30

### ****- "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.
-- KF4ZMA, 2023-05-16

### ***-- "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.
-- WYCowboy911, 2023-03-06

### **--- "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
