Faulty Cleartone CM5000

Already quite some time Ive had a Cleartone CM5000 in my shack, waiting for some further investigation. The radio was sent to me by an OM because the radio showed an error on startup. After switching on the radio the gruesome message ‘Security (K) error’ appeared. It’s not completely sure, but it’s likely that somebody […]

DMR thoughts

‘Do you quit DMR?’ This question was sent to my by mail about half an hour after I’d put my Hytera handheld for sale on a second hand website. ‘Did I ever start it?’ was the question I was thinking of… Some years ago I’ve been playing around with DStar. I’ve been using an Icom […]

Motorola MTM800: what’s in a name?

When involved with tetra radios by Motorola you’ll unavoidably meet the MTM800. In it’s first appearance this radio looks like an analog Motorola GM380: rounded edges and a monochrome display. Furthermore this radio only distinguishes from it’s predecessor the MTM700 by some extended functionality. But from the optics both MTM700 and MTM800 are similar.   Then […]

This network has been developed and rolled out as an initiative of Aachen University and is meant to be the replacement of the old FunkrufMaster. Just like the old system this network consists of a couple of […]

New frequency for Echolink node

For some reasons it was necessary to change the frequency of the Tetra Echolink node. As of today the node can be reached via 430.9250 MHz. All other parameters have remained the same: GSSI: 1000 MNC: 7373 MCC: 204 The new QRG has also been entered in the SVXLink configuration, so the Echolink status website […]

Tetra ‘fleetmap’

Just like for instance DMR Tetra uses different parameters to determine the hierarchy in the network. Of course these parameters have to be programmed in each radio to make sure connections are setup correctly. These parameters are: MCC: Mobile Country Code MNC: Mobile Network Code GSSI: Group Short Subscriber Identity ISSI: Individual Short Subscriber Identity […]

PE2KMV-L up and running again

After the node had been switched off yesterday, everything is back to normal again today. Issues arose yesterday while swapping node transceivers. Already some time ago a Motorola MTM800E had arrived. Yesterday the moment had come to switch of the ‘normal’ MTM800 and fire up the MTM800E. But then it appeared that the audio signal […]
