## What is iWSPR TX?

WSPR it's a protocol, developed by K1JT Joe, designed for probing potential propagation paths with low power transmissions. Normal transmissions carry a station callsign, maidenhead grid locator, and transmitter power in dBm.

This App, used in combination with an hamradio transmitter, allow you to send a signal that, if received by someone, will be reported on wsprnet.org. 

This is also great tool for checking your antenna system or comparing two radio,

Inside the App you will also find the connection schema, under "Help" menu, for radio with VOX and PTT!

Have fun! 73!

### 4/5 — Exactly 1/2 of what I need

*2023-03-13*

The transmitter side works well. It would be really helpful if it could also decode.

### 2/5 — Maybe Tx, Maybe No Tx

*2022-06-26, version 3.0*

It transmits at random times.

The fatal flaw in this program is that it does not warn you when it plans to transmit next.

I want to be in charge of my station and not have this app be the control operator who does not communicate with me.

### 5/5 — Easy to use app with excellent customer support

*2021-01-25*

In my opinion it’s the best app out there and it’s for Apple!! The whole thing was easier than I imagined using an existing FT-857d. Great fun especially with using a beam and low power. Watch the propagation change. Federico is a really helpful guy assisting with interface cable issues. If only all companies offered this high level of customer service. 100% recommend. Gary MW0YAE

### 5/5 — Worth the money

*2021-01-13, version 2.94*

Great App, although it can be done for free with a computer or android tablet, I have an iPhone and iPad that I bring with me to portable operations and I have a mobile setup and this is perfect. Easy to use and it has been great for testing my antennas. I wish there were more options for the map, such as the ability to specify how far back to show pins and what bands to view. Maybe this is an option I just haven’t found yet.

### 4/5 — Exactly what I was looking for

*2019-03-03, version 2.8*

This app is exactly what I need: to be able to do wspr beacon antenna testing using my phone and portable rig. Easy set up and operation. I run it and hold the rig mic up to the phone. Nice product.

### 5/5 — fantastic app

*2017-10-23*

iWSPR works flawlessly to transmit WSPR messages.

I have used it with both a KX3 and an IC 7000, using vox on both.

Pay attention to your ALC levels so that you do not distort your transmitted signal. Distorted signals may not be copied by monitoring stations.

I am looking forward to the receiver being implemented.

### 5/5 — Great support

*2017-03-09, version 2.4*

I have even very pleased with this app driving my KX3. It is very easy to set up when you want to make a quick WSPR test. I had a question regarding one of the setup parameters and received a quick email response with a clear explanation. 

Good software, thanks!

### 5/5 — M6vio

*2017-02-06*

Brilliant app. Using a a heil headset adapter out of mic socket via a 3.5mm stereo to mono plug and cable straight to iPad or iPhone headphone/mic. Keep the volume low on device and works great.

### 5/5 — Great App for the iOS..

*2016-07-31, version 2.4*

Have been using this with a FT-817ND & KX3. Works GREAT and you always seem to have your phone around.. GREAT WORK on this one..

### 5/5 — IWSPR

*2015-11-04, version 2.11*

Works perfect! Audio frequency is right on, clock time is perfect somehow.
