9th of July 2016, a few weeks ago when we replaced the antenna for PI1SHB and added an extra antenna for 2.4 GHz to make an interlink connection between the locations from PI1SHB and PI2SHB.
Last weekend we were at the PI2SHB location to place the other 2.4 GHz antenna for the interlink connection.
The white flat building afar is the location where PI1SHB is located, the distance in a direct line of sight is 2,15 km (1,33 mi).

Using laptop to see how strong the signal is and to set the antenna in the right direction.
The Wi-Fi interlink connection works immediately and the signal is strong enough for a stable connection between the locations.
Now we need some time to test, and hope to add new features soon !
24th of June 2016, today we’ve been busy for the whole day to replace a new antenna and coax cable for PI1SHB.
The old antenna was a Maldol VT-160D dual-band antenna for 2m and 70cm (Diamond X50 clone), and was more than 15 years old.
The 2 yagi antennas for 23cm are removed, they are not in use anymore for a few years.
This was the old setup for PI1SHB packet node, active on 2m and interlink connections on 23cm between PI1EHV (Eindhoven) and PI1RNI (Utrecht).
Paul (PE1LXX) and Arie (PD1ANF) removing the old antennas.
Paul (PE1LXX) prepares the mounting clamps for the new antenna on the pipe.
We replace a Diamond X300N dual-band antenna for 2m and 70cm to improve the coverage in our area.
We see much stronger signals with this new antenna, so we’re happy to see the good results !
Later today we placed antennas for HAMNET, a wireless connection between the location from PI2EHV/PI6EHN in Eindhoven and us on 5 GHz.
The other 2 acces points are for local use, beaming to east and south directions.
12th of June 2016, PI2SHB was not operational today due maintanance on the repeater.
There was a small problem in the power supply and the problem is solved.
PI2SHB is back operational and is ready to use !
27th of March 2016, after a few weeks of thinking how we can realise EchoLink on PI2SHB we now have a test setup !
The hardware we use for the test setup is :
– Raspberry Pi 2 (Model B)
– Homemade interface
– USB soundcard
– USB to RS232 serial converter
– 2.4 GHz Wi-Fi external antenna
– Kenwood TM-451E
The EchoLink controller software is SvxLink (made by SM0SVX in Sweden), and have a lot of features.
In the next few weeks we want to tweak the settings and hope to realise a 24/7 EchoLink connection on PI2SHB.
Below you see some pictures about our test setup.

The homemade interface to connect the tranceiver with the controller.
5th of March 2016, we’ve made some small changes at PI1SHB.
- Because that we’ve had some problems with the I²C bus, we changed the 2m TNC-Pi connection back from I²C to a serial port.
The 70cm TNC-Pi is still running on I²C and works fine for now.
- Added 3 club station object beacons for PI4SHB, PI4OSS and PI4TIL, it transmits every 20 minutes.
21th of February 2016, we installed a new RF front end for PI6SHB, the analogue 23cm voice repeater for ‘s-Hertogenbosch.
The receiver sensitivity is much better than before, so the receiver problems are solved now.
PI6SHB is transmitting on 1242.350 MHz, the input frequency is 1270.350 MHz and can be opened with a 71.9 Hz tone.
22th of January 2016, we installed new equipment at PI1SHB, the APRS digipeater/IGate for ‘s-Hertogenbosch.
Replacing the radio’s for Motorola GM350 radio’s.
In the old setup we used a Kenwood TM-V7E (2m) and Kenwood TM-451E (70cm).
A second TNC-Pi was installed to replace the TNC2S-DK9SJ 70cm test setup.
All of the new equipment is installed in a new 3HE 19 inch case.
– 2x Motorola GM350 radio’s
– 2x TNC-Pi
– 12 volt power supply
– 12 volt to 5 volt power converter
– Raspberry Pi
At the moment there is a problem with the 70cm Motorola GM350, so we used temporarily a Kenwood TM-V7 for 70cm.
We hope to replace the 70cm Motorola GM350 soon.
