Please note: The chronological order is approximate

PTC108 (1949)

The PTC108 was the first Pye Telecom dash-mounting mobile and was quickly made available as a battery transportable version for use in the field.

The equipment is mentioned in the 1949 Pye Radio-telephone equipment catalogue, however to date no examples or photographs have been found of this equipment version.


PTC112/113 (1950)

PTC107 complete system

A local control, battery powered transportable version of the remote mount PTC112/113 was made available as a replacement for the PTC108 which, being based on the original PTC104 equipment, did not remain long in production after 1950.

The PTC112/113 transportable equipment was mounted in a wooden case and a separate container was used for the battery or mains power supply.


PTC126/PTC127 & PTC128/129 (1950)

The long running Pye Reporter series was also made in a battery transportable version. The Reporter mobile was contained in a wooden carrying case and a 12 Volt lead-acid accumulator mounted in a separate steel case provided power. The PTC126 & PTC127 were the standard equipment models for low band and high band and the PTC128 & PTC129 were versions fitted with an internal AC mains power supply which would automatically change over to battery operation if the mains supply was not present.

Weight: 33lb. (15Kg) plus 45lb. (20.4Kg) for battery case.


PTC2012 & PTC FM8012 Handi-Ranger (1956)
PTC2012 transportable

The Pye Handi-Ranger was an integrated battery-powered transportable built from Ranger chassis modules mounted in a splash-proof aluminium case. The carrying case contained a 6 or 12 Volt accumulator, an internal loudspeaker and a rod aerial. An external waterproof plug-in microphone was mounted in a holder. The PTC2012 model was based on AM Ranger equipment and the PTC FM8012 based on FM equipment.

Weight: 20lb. (9Kg) including battery.


AM10P/FM10P/CM10P Handy Cambridge (1963)

AM10P transportable

The AM10P/FM10P/CM10P Handy Cambridges were a family of transportable mobiles constructed using modified boot mount Cambridge chassis and case parts. Both AM, FM and FM-Marine versions were available in single or 6 channel configuration. The Marine version had a low/high power switching facility. A choice of batteries was offered; either a sealed lead-acid battery of 9Ah capacity or nickel-cadmium cells of 6Ah capacity. These were mounted in a detachable container at the base of the unit. An internal speaker was fitted under a lid which covered the controls, a quarter-wave fibreglass whip aerial (fitted with a PL239 connector and elbow adaptor) could be mounted on one side of the equipment case and a water-proof microphone clipped onto the other side. Later models were fitted with a helical whip aerial. The battery charger used was the BC2.

Weight: 20lb. (9Kg) with NiCd battery or 22lb. (10Kg) with lead-acid battery.


MF5AMP Portafone
MF5AMP Portafone

The Pye Portafone was an aluminium transportable carrying case which housed a MF5AM Motafone or Pye Pilot mobile. It provided a suitable battery and a vertical whip or helical antenna. The rechargeable NiCd batteries used had a capacity of 3AH and a dry battery cassette was available as an option. Battery charger type BC2/P was used with this equipment.

Weight: 7.5lb. (3.4Kg)


P15PU Westminster Transportable

This conversion unit enabled the standard dash mount Westminster to be used as a man-carried portable, and was used by both commercial and military customers. The standard unit contained a 4 Ah NiCd battery pack, loudspeaker and retractable telescopic antenna. An optional leather carrying case was available.

A version with higher battery capacity was supplied to the British Army for Platoon use.

The battery charger used was the BC2.

Weight: 13lb. (5.9Kg)


P200PU Universal Transportable Unit

P200PU Transportable

The Pye P200PU battery transportable carrying case was originally designed specifically to support the M200 Olympic mobile series. Due to the size and aspect ratio of the Olympic equipments, the P200PU was also able to be used with the older MF5AM Motafone, MF5FM and MF25FM Europa equipments.

The P200PU was also used for the newer MF6AM Reporter and later when the Olympic family ceased production, the M290 and MX290 equipments. To support the use of these various equipments with their differing current consumption and RF output powers, two sizes of NiCd battery packs were made available; a 4.0 Ah unit and a 7.0 Ah unit, both with a nominal voltage of 14.4 Volts (which is higher than the usual 12.5 Volt battery packs used in transportable mobiles). The battery charger used was the existing Pye BC2/T constant-current charger.

Weight: 6kg with 4 Ah battery, 7kg with 7 Ah battery.


M252 Pegasus man-portable

M252 Pegasus

The M252 Pegasus mobile could be quickly slotted onto a NiCd battery pack container to form a self-contained transportable station. This was called the ‘Man-Portable Conversion Kit’ in military parlance.

When the Olympic/Pegasus mobile family ceased production, the Pegasus battery pack was used with the FM900 radio unit and a dedicated control box to form a replacement equipment, the FM914PM.

The product used valve technology for the receiver and transmitter, and had a transistorised power supply. The receiver circuits would appear to have been taken from the Ranger PTC2001, the transmitter from the PTC116 Reporter and the dc-dc inverter power supply from the Cambridge. The product pictured here has the serial number 000022.

P135 Falcon Transportable (1982)

The construction of the transportable carrier for the Pye New Zealand P135 Falcon AM mobile was very similar to the P15PU Westminster unit.

TP92 FM92 Transportable (1988)
TP92 FM92 Transportable

The Philips TP92 was a battery powered transportable carrying kit for the FM92 series of dash-mount mobiles and was of similar construction to the Westminster P15PU portable and the P135 Falcon transportable units. Two 6 Volt 10Ah sealed lead-acid gel batteries were used for power.

Weight: 10kg (22lb) with batteries


FM914PM Transportable
FM914PM Transportable

The FM914PM was a transportable version of the FM91 remote mount mobile, mounted on the M252 Pegasus transportable battery container.

When production of the M252 Pegasus finished in the mid 1980s, this configuration of the FM91 was supplied to the MOD for use on the Mould home-defence network and for other applications. As the core FM91 radio was a remote mount it was necessary to provide a water-proof control head for this application, and this was fashioned out of a die-cast box. The M252 external signalling unit could also be attached.

FM1000 Transportable

The industrial design concepts for the stylish FM1000 transportable were designed by Michael Goatman FCSD, who was also responsible for the industrial design of the PRM80 mobile, the DCU900 data unit, the PRP70 portables and the Simoco SRD1000 desk-top controller.

The FM1000 transportable equipment was intended to be used as either a hand-carried portable or a desk-top unit, hence the folding handle which also functioned as a support stand.

The creation of the FM1000 transportable was stimulated by the success of the Storno CQM6000 transportable equipment, and at the marketing specifications stage the unit was intended to be constructed using an aluminium die-cast frame. However the final product implementation used an FM1000 mounting cradle in plastic mouldings which did not provide a significant ground plane for the antenna. The equipment is therefore more stable if the transmit output power of the FM1000 radio unit is turned down to 6-10 Watts.
