The PRM80 series of radios.

These are more modern day units (circa 1989) which offer a plethora of features all customisable with software, remote head or single piece units, 10, 64, 100 or 200 channel units, and trunking variants were available, too.  Alphanumeric channel names were available on one model, the 8040.  All this in a radio that is somewhat smaller & lighter than the FM900, modern-day styling, highly interference resistant and very sensitive to weak signals.  The PRM80 series of radios have been replaced by the Simoco 9000 series radios, though the PRM80 series continues to be supported.

The PRM80 family consists of:

*PRM8010 - a local mount only, 10 channel version with a single digit display (two digits for the trunked version) and only four function buttons, CTCSS and fixed SelCall system.

Was also known as Mobria R20 in Scandinavian countries.

*PRM8020 - a local mount only, 64 channel version with 4 digit display, eight function buttons, CTCSS and variable SelCall system, and scanning

Was also known as Mobria R21 in Scandinavian countries.

*PRM8025 - a local mount only, 100 channel version with 6 digit display, eight function buttons, CTCSS and variable SelCall system, and scanning and voting

*PRM8030 - a remote mount, 100 channel version with either 4 digit remote head or optional 6 digit remote head, eight function buttons, CTCSS and variable SelCall system, DTMF and scanning and voting

*PRM8030 Dual Mode - same as the PRM8030, but additionally can have two trunking networks programmed in (the trunked network feature is not much use to us hobbyists, even for receive only, since the unit must 'register' with the network)

*SRM8038 - like the PRM8040 (and uses the same main unit) with an alphanumeric display with keypad, similar but slightly fewer features, more modern styling.

*PRM8040 - a remote mount, 200 channel version, with alpha-numeric display remote head, function & full keypad built in, CTCSS and variable SelCall with memory list, DTMF, scanning and voting.  Top of the line PMR unit, produced only in Australia

*PRM8041 Dual Mode - same as the PRM8040, but can have trunking networks programmed in as well as the PMR channels.

UK models:

*8060 Band 3 (175-220MHz) trunked visually identical to 8010

*8070 ditto 8060 but like 8020

*8061 data mobile without display for such as Fire Service mobilising, mainly E-band (68-88MHz)

Bands available:

E0 = 66 to 88 MHz

B0 = 132 to 156 MHz

A9 = 146 to 174 MHz

K1 = 174 to 208 MHz

KM = 223 to 235 MHz

R3 = 330 to 400 MHz

TM = 400 to 440 MHz

TU = 403 to 470 MHz

T4 = 425 to 450 MHz

U0 = 440 to 470 MHz

UW = 450 to 520 MHz

W1 = 470 to 500 MHz

W4 = 494 to 520 MHz

X = 800 MHz trunking bands

Dedicated trunking units are also available, but are not much use to us in this form.

They cannot be used as standard two-way radios (i.e. PMR mode), although with replacement of the firmware EPROM, they can be used as a normal PMR radio. Other mods are required (0 ohm SMD resistor jumpers) to enable SelCall signalling.  Models included 8025T (curiously labelled as 8020T), 8030T, 8041T, 8042T, 8060T, 8070T, and supposedly a model that looks like an 8010.  Certainly a dual mode unit can be transformed into a single mode unit by replacement of the EPROM and altering some jumpers - not that there is much point in doing this, because the dual mode units can be programmed in PMR mode anyway.

Various options are also available, such as:

*6 digit local or remote heads - used to upgrade a PRM8030 or 8020T from a 4 digit head

*DTMF microphone - can be connected to any of the PRM80 family to transmit

DTMF tones, useful for those radios that do not have built-in DTMF capability.

*Controller (keypad) microphone - looks almost identical to the DTMF microphone,

but can be used to obtain extra functions on the radio, and directly enter SelCall numbers etc.  

This microphone will only work on 6 digit heads (i.e. 8025 or 8030 with the optional 6 digit head)

*Power supply & console unit (for 'base station' use)

*Power supply & remote console unit for remote control base station use.

*Modem card (for transmission of data, and programming the radio personality)

*voice synthesizer card for trunking operation

*quick release mounting bracket

*cross band repeater cable kit

*hands free microphone set up

*covert microphone

*telephone style handset

*transportable kit

*alternate speakers

*numerous outboard options - MAP27 data interface, GPS & AVL systems, etc etc
