EchoHam / New EchoHam version 2.25
« Last post by support on January 29, 2023, 03:37:58 pm »
The last 3 releases included many code improvements with some of the old Objective-C modules completely re-written in Swift.
V2.25 provides the ability to set specific audio devices for use with EchoHam via the preferences window.

Since some audio devices can be temporary (e.g. bluetooth earphones getting disconnected), EchoHam will not complain when a pre-set audio device is not available, instead, it will revert to the default device specified in system preferences.

To always use the audio settings from system preferences you can set the audio devices to "Default" in EchoHam.
Using default devices has the advantage of devices automatically changing as required by the system.
EchoHam / New EchoHam V2.20/21 - with proxy support
« Last post by support on December 29, 2022, 06:38:02 pm »
V2.21 has been submitted to the AppStore for approval and should be available for download in the next few days.
It took a while to implement proxy server support in the code but hopefully this will fix the most common user problem reported over the years, which is the port forwarding setup on routers.

Here is an explanation and demonstration of the proxy server support feature:

I would expect some bugs to show up as the proxy server code required modifications in most of the code modules.
I ask for your assistance in resolving the bugs.
Before reporting a bug please make sure it is repeatable and that you record the exact steps which lead to the bug so I can re-create the bug and try to resolve it in the next version.
You can email all bug reports to me: support AT gmail DOT com
Modbus Server / New Modbus Server(TCP) and Slave(RTU) application
« Last post by support on September 08, 2022, 12:05:14 pm »
Modbus Server has been completely re-written using the latest Apple SDK and Network Framework.
Unfortunately it was not feasible to accommodate the new features in the old version so we have now created two new applications:
  • Modbus TCP Server
  • Modbus RTU Slave (to be published soon)
Splitting the RTU and TCP functionality has come as a result customer confusion with the server/client (TCP) and master/slave (RTU) terminology. We re hoping the new terminology leaves no room for confusion.

EchoHam / Re: Firewall or Router Configuration Error
« Last post by support on September 08, 2022, 11:53:44 am »
The error message states:
"other stations won't be able connect to you"

It it trying to tell you that, when you have EchoHam running, another station might not be able to contact you.

Can you please clarify if you have been successfully contacted by another station?
EchoHam / Firewall or Router Configuration Error
« Last post by Sgtmom on August 26, 2022, 12:18:25 am »
When I open up EchoHam, a window pops up indicating that there is a Firewall or Router Configuration Error, and states the following: 
"Unable to receive data. Outgoing connections are working, you should be able to connect to other stations.
Incoming connections are not working, other stations won't be able connect to you.
Port 5198 failed. Port 5199 failed.
This problem may be due to incorrect firewall or router setting."

The problem I have is that, the software is working perfectly, so I am somewhat confused by the error.  I have used it several times and have reports that my transmissions are being heard clearly, and I in turn can hear others clearly.  Not sure what to do about the message or if there is still some type of an issue I am not aware of. 

I am a new ham and have only used EchoLink on my phone, and since this seems to be working, I am not sure how to proceed.
If there is no problem, the error message is just an annoyance, that I can live with, but I would like to make sure.
