Cupholder mount

As the interior of a modern car often offers limited space and because it’s a pity to drill holes everywhere I’ve been searching for a way to mount the head of a (Motorola) radio in a non-destructive way. Also a larger car offers almost no options to mount a radio. But I’d found one spot […]

Codeplug hassle

A fellow ham had asked me whether I could program a couple of Motorola MTM700 tetra radios for him. To do so I could use my home made programmer. And it seemed I also had the sofware for the MTM700. So I was able to quickly read one of the radios. Nevertheless it’s quite hard […]

Double the value of an Inrico!

Some time ago the Inrico ‘network radios’ saw the light, together with similar device by exotic brands. The units look similar to portable or mobile transceivers, but that’s also the end of the similarity. In fact these ‘network radios’ are nothing else than Android based smartphones with an MTK board. A PTT button has been […]

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 […]

SMS functions via DMR

The Brandmeister network has some functions to request information via SMS messages. To access these functions specific keywords are to be sent to DMR ID 262993. Then the system responds as well via SMS on these requests. Below you’ll find an overview of these commands with some explanation. The commands are not case sensitive.   […]


Since some time the dutch POCSAG transmitters have been linked to the german DAPNET, Decentralized Amateur Paging Network. 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 […]

First 2m simplex QSO from the KWA tunnel

On Friday February 10th. 2017 probably the first QSO took place from the King Willem Alexander tunnel in Maastricht. While driving into¬†the tunnel I’ve had a QSO with Pascal PB1SAM who was also driving home from QRL. At the time I was entering the tunnel he took the old northbound A2 route at the surface […]

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 […]
