We’ve installed new hardware for PI1SHB.
Replaced the old Raspberry Pi (model B) computer for a new one with more CPU capacity and RAM.
We have improved the audio levels for both bands, and tweaked the TX delay and TX tail times.
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.
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.
