The hamradiocluster PA0ESH-3 has been moved to another domain. You can now reach it at pa0esh.freeddns.org. Still using port 7300,
Please update your cluster software such as log4om, N1NN etc.

FT911A Transmit icon hangs
I solved the issue of the transmit icon staying in blinking mode and not due to hanging PTT or others </p
Procedure:
- Switch OFF your FT991A.
- Power and USB have to be physically disconnected. Pull the connectors.
- Wait for 30 seconds
- Re connect the PWR and USB and switch the FT991A to ON
That’s it !
RS232-TTL
Once upon a time somewhere in 2015 i bought a couple of these little converters RS232 tot TTL.
Here is how they work
From the RS232 Port – RX, TX and GND. Thats the -> -<and the – signs. Easy enough
– GND
-> RX
<- TX
On the TTL (Arduino) side – DO NOT USE 5V use 3.3V as this toasts the device and heats up and like tops itself. It certainly got very toasty when I put 5V across it. This could be because I messed up somewhere in the wiring but it certainly works well for me. I can also use the SoftwareSerial library as well so I don’t need to use TX/RX on the TTL Serial pins 0 and 1
So TTL is
– GND
-> – PIN X
<- PIN Y
For my device I used PIN 0 and PIN 1 – TX/RX – but I guess you can use other pins.
Hope this helps – it does work!

Openwrt/Lede & APRX
Just before years end i have compiled the latest OpenWRT LEDE & APRX, and added OpenVPN and OpenSSL to it. The files can be found in the download section. If you have another router, then drop me a line, or call me at DMR at 204 / 2044 or 2045.
Openwrt/LEDE and APRX – New !!!
Openwrt and LEDE have combined forces, and the new firmware including the latest aprx 2.9.0 package is available for download.
Older versions are no longer maintained.
See the respective page on this site.
Latest Openwrt for ASUS WL500G
I have just posted new images for running aprx with Openwrt on a Asus WL500gP. If you need another image for another outer, please let me know.

Latest Openwrt – APRX images – 19-05-2017
I have added new firmware packages and the latest APRX package in the download section. In case you need firmware for another router, please let me know and I see what I can do.
To install just the package, do as follows….
ssh into your machine (normally something like sss root@(ip-of-machine)
Then change into the tmp directory and execute:
/etc/init.d/aprx stop
wget https://www.pa0esh.com/svn/aprx_2.9.0-Stable_brcm47xx.ipk
chmod 755 aprx_2.9.0-Stable_brcm47xx.ipk
opkg install aprx_2.9.0-Stable_brcm47xx.ipk
In case the installer tells you that you have already the latest package, change the command into:
opkg install aprx_2.9.0-Stable_brcm47xx.ipk –force-download

Updated md380tools script
The script to install and maintain the md380tools has been updated to version 3.2.
New is that the script checks if there is an update available from GitHub.
APRX 2.9.0
The latest firmware images for Openwrt & APRX have been uploaded in januari 2017. See the download section.
Ans see Google groups for more info…. https://groups.google.com/forum/#!forum/aprx-software
To install just the package, do as follows….
ssh into your machine (normally something like sss root@(ip-of-machine)
Then change into the tmp directory and execute:
/etc/init.d/aprx stop
wget https://www.pa0esh.com/svn/aprx_2.9.0-Stable_brcm47xx.ipk
chmod 755 aprx_2.9.0-Stable_brcm47xx.ipk
opkg install aprx_2.9.0-Stable_brcm47xx.ipk
In case the installer tells you that you have already the latest package, change the command into:
opkg install aprx_2.9.0-Stable_brcm47xx.ipk –force-download
You can test which version you are running:
type aprx -V from the prompt
currently on openwrt the version nummer is not correct but instead will show: 5.05-333-g160eb5d
/etc/init.d/aprx restart
