Automatic control couples the attenuation to the reference level. Note that setting the attenuation using this command

automatically sets the attenuation coupling to “MANUAL”, thereby allowing it to be defined independently of the reference

level.

Set AM/FM Demodulation – Control Byte #145 (91h)

Description: Sets the AM/FM/SSB Demodulation state. This command is also used to set the type of Modulation, volume,

Demodulation Frequency, BFO Adjust (SSB only) and the Demodulation time. On turning demodulation ON, after exiting

remote, at the end of every sweep, demodulation is performed at the Demodulation frequency for a period of time specified in

the Demod Time.

276 00h = FM Wideband, 01h = FM Narrowband, 02h = AM, 03h = SSB Lower, 04h = SSB Upper

277 Speaker Volume is from 0 to 100 in steps of 10

278 Demodulation time in milliseconds from 100 millisec to 500 seconds

279 If Option 6 is installed and the frequency converter module is attached, the frequencies should be scaled by the scale

factor of the module. If the module is not attached, the frequencies are sent in Hz. Use Control Word A203 to

determine whether a module is attached and the appropriate scale factor.

280 BFO Valid Values are -10 kHz to +10 kHz. Send value as BFO (in Hz) + 10,000. For Example -10 kHz would be sent

as 0, 0 would be sent as 10000 and +10 kHz would be 20000
