Discuss Stornophone 6000

Stornophone 6000

The Storno 6000 series first appeared in 1985 in the form of the PRM6000 NMT mobile telephone and 1986 saw the arrival of the CQM6000, introduced as the multi-purpose radiotelephone for the information age.

Design Features

The CQM6000 was a DIN compatible package with the radio case made from a cast aluminium chassis with integral heatsink at the rear. The basic chassis was available with an extensive range of control hardware allowing local, remote and multiple head installation, transportable operation, waterproof installation and interface to external data devices.

CQM6000 Synthesiser

Technical Developments

The CQM6000 was the first radio which had the hardware to live up to the promise of total software control flexibility. Featuring a broadband synthesiser with varicap RF tuning the set could use channels anywhere in it's frequency band and allowed both 6.25 and 5 kHz steps. Tone signalling used digital signal processing, permitting any combination of selective calling systems to be used including binary 1200 baud FFSK and DTMF.

CQM6000 Daughterboards

System Capabilities

The CQM6000 was the ultimate systems mobile with packages supporting conventional, trunked, scanning, data and encrypted speech systems. Flexibility was enhanced by the 16 character vacuum fluorescent alphanumeric display allowing complex user interaction and messaging capabilities. Additional systems hardware was available using daughter boards for features such as CTCSS decode, receive signal level monitoring, encryption, etc.
CQM6000 Control heads

CB6000 Control Heads

A variety of control heads were available, the most commonly found being the CB6001 with the auto dimming 16 character VFD display, 24 button backlit keypad, 10 function and 3 volume level display LEDs. Variations included simplified keypads, waterproof units and reduced size options suitable for motorcycle installations. Alternatives to the green display were also supplied, particularly for railway use to avoid risks of mistakenly observing green signals.
CS6001 Codeplug

An optional feature on the control head was a socket for a personalised codeplug. As well as defining the individual signalling codes used, the codeplug could also be used to enable and disable specific channels. The standard codeplug contained a 256 bit serial EEPROM and contents could be edited using service mode. Larger capacity devices were also available which could be fitted inside a junction box.

Transportable CQM6000

CQM6000 Transportable

This unit was not called a CQP6000 because it was not a separate model but just a standard CQM6000 with a control head featuring an integral handset and PTT switch and dropped into the carrying case. Medium and high capacity batteries were available and could be charged in-situ with a supply cable connected to the case. Many software packages automatically set transmit power to a reduced level when in the case and this feature can be used to implement an external QRP power level switch.

Duplex CQM6000

CQM6000 Duplex

Rare by comparison to standard sets the duplex model can easily be identified by the larger heatsink, thus permitting a 100% transmit duty cycle. Variants included those used as repeater units consisting of separate transmit and receive chassis and also mobiles fitted with an internal duplexer, although this meant frequencies were limited to a particular part of the band.


PRT6000 Radiophone

Special Duplex mobiles and transportable versions of the 6000 with integral handsets in various forms were developed for the European mobile phone networks on 450MHz and later also 900 MHz.

CQM6000 Control board

CQM6000 Software

A vast array of custom software packages were developed for the Storno 6000 and there were a number of different hardware revisions of the main control logic board so not all combinations are compatible. The standard software package for CQM6000 was called Opus. There were three versions, EC was an early version, EF was the most common and EL was the version used in radios with encryption. The EF and EL versions could be configured using a DOS PC based programmer either by creating EPROM images or uploading direct to EEPROM via an interface box talking on the H-Bus which communicates with the control heads.

CQM6000 Service Mode

CQM6000 Service Mode

Many software builds based on standard packages incorporated a service mode allowing direct control of the radio hardware using test routines selected by keypad entry. This was particularly useful for troubleshooting, especially on trunked radios with no conventional channels. It also allowed direct editing of the personality EEPROM and could be used to modify the codeplug data.

CQM6000 Installation


The Storno CQM6000 series was available with a wide range of installation kits from a simple DIN frame to a quick change kit allowing the radio to be exchanged without having to swap connections. The radio was retained in the bracket by a sprung pawl that could be released using the special key provided.

Motorola Staccato


The Motorola branded version of the CQM6000 series was called the MC Spectro but a lower tier model was also designed by grafting the control circuitry of the 6000 onto the RF circuitry of the Motorola MC Micro. The result was badged as the Staccato providing flexible signalling options but without the RF agility.
