NOTE: If an external interface is wired to the DTR line and DTR for D.C. Power is checked, the DTR line

will be held high, thus if that line is used for PTT the radio will always be keyed until either DTR for

Power is unchecked or any jumpers of diodes in the interface are opened. .

To make use of the radio port RTS line for PTT, if supported by the radio type being used,

hardware handshaking can not be used as the RTS/CTS lines are already being used.

NOTE: If an interface is already in use where RTS is normally used for PTT and DTR is used for D.C.

Power, but it is desired to make use of hardware handshaking, should the interface have a VOX switch

(such as older RigBlaster models) and the radio support CAT PTT, then placing the interface switch into

VOX and selecting CAT PTT is an option that works.

CHAN -

If the Radio Type selected supports the option of using radio memory channels or only supports the use of

memory channels than CHAN shall be listed.

NOTE: CHAN shall denote support for the given radio model for Radio Memory Channel based scanning

which is ENABLED/DISABLED using the MMI commands ENABLE CHANNEL or DISABLE

CHANNEL via the Data Bar when MMI is checked if the radio in question optionally supports this

method. If CHAN is the only method the radio supports then CHAN ONLY will be listed, in which case

the MMI commands have no effect.

The radio memory channels must be programmed to match the PC-ALE Scan Group channel numbers so

that the listed channels that make up the scan group are properly selected in the radio.

CAT MUTE -

If the Radio Type selected supports a CAT MUTE command or CAT Volume control then CAT MUTE

shall be listed.

NOTE: CAT MUTE shall denote support for CAT MUTING where it must be enabled via the MIL-STD-

188-141 Options Dialog along with the method being selected if the radio supports more than one method

of muting. For CAT Volume Level Muting a MUTE and UN-MUTED level must be provided. .

When a radio does not support CAT muting at all, the only MUTE operation will be RTS/DTR for

MUTING if enabled by “Use DRT for Mute” or “Use RTS for Mute”.

CAT MUTING is optional for radio muting whereas a selection can be made between CAT vs. RTS/DTR

for MUTING via a check box on the MIL-STD-188-141 options dialog. In addition, as a number of radios

support both CAT Speaker Audio Level and a CAT MUTE command there is another check box is

available to select the Level method when a radio supports both methods.

CAT MUTING requires that line audio output from the radio be fed to the ALE modem and not speaker

output. With RTS/DTR the speaker output can still be used as long as the pickup is on the swinger of the

relay directly from the radios aux speaker port.

NOTE: For Kenwood radio type selection the RS-232 cabling and the signal lines must allow for the radio

ID to be read from the radio to know that the Kenwood model being used supports CAT MUTING. .
