This procedure does work..!

Setting up AM transmit
AM transmit capability has been added to the Jupiter and
Pegasus transceivers. The transceiver must be adjusted
before using AM transmit to set the carrier level. The
carrier level should be adjusted to 25 Watts or less.
The basic steps are similar on the Jupiter and Pegasus
transceivers. In addition, the Jupiter has an additional
auto-set mode. The microphone gain should be adjusted in
SSB mode to prevent over modulation while in AM mode. If
you are already using the transceiver in SSB then the setting
should be fine. Presently AM Transmit Bandwidth is not adjustable.
JUPITER 538
On the Jupiter, two controls operate differently while in AM mode.
The PWR setting control changes to become AM DRIVE control. This
control is used to adjust the carrier level. The TUNE button
activates a function called AM-AUTO-SET. When TUNE is pressed the
transceiver will turn on the transmitter and adjust the AM-DRIV
control for a nominal 25 Watt carrier. It takes the transceiver
several seconds to perform this operation. When the process is
complete the transceiver will return to receive. It is important
to know that during this process the output from the transceiver
will be a full 100 Watts. A dummy load should be used and any
amplifiers in line should be switched to bypass. After the AM-AUTO-SET
the AM DRIVE control can be used to adjust the output if needed.
The PWR setting is not accessible in AM mode as AM DRIVE is used to
adjust the power output.

Subject: [TenTec] AM operation
Has anyone out there any experience running AM on the Jupiter?
I pressed the TUNE button while in AM mode but didn't see anything
change as I expected - AM drive, mic gain, etc all stay the same values.
The jupiter's meter shows 14 watts out and just sits there until I
press TUNE again to make it stop.
Any ideas/suggestions?
Thanks!
