[1000mp] Sound Card - FT1000MP

[George Vincent K3GV]

I know I have posted this on the reflector before, but here it goes again.

You do not need an interface with the FT-1000MP (plain vanilla). I have had
mine hooked up to a soundcard for several years without any problems
whatsoever. Simply hook up the AF OUT on the MP to the LINE IN on the
soundcard and hook up the SPEAKER on the soundcard to the PATCH on the MP.

Yaesu has provided a simple solution to run packet in USB in the old MP
using the USER function:
Here it is:

Configuring the FT-1000MP for USB-side Operation in the Packet Mode
for
MARS Operation
Although the FT-1000MP's Mode selection does not allow the use of USB-side
injection during "PKT" (Packet) operation, it is possible, through Menu
programming of the parameters of the "User" key, to configure the FT-1000MP
for USB-side injection in the Packet operating mode for MARS use.
Procedure
1. Enter the "Menu" mode by pushing and holding in the [FAST] key and then
pushing the [ENT] key on the keypad momentarily.
2. Rotate the [MEM/VFO CH] knob to select Menu Item 8-6.
3. Now set up the parameters in each category shown below. These parameters
will shift the various oscillators, while in the "PKT/LSB" mode, so as to
place them at the frequencies they would be in if there were a dedicated
"PKT/USB" mode. In effect, you are creating such a mode by using the "USER"
key setup capability.
Mode Disp. Offset RX-PLL RX-CAR TX-PLL TX-CAR*
PKT LO +2.125 kHz +2.210 kHz 452.790 kHz +2.210 kHz 452.790 kHz
* Prior to Production Lot #05, the value for "TX CAR" could not be set below
456.300 kHz. For these earlier versions, the use of 456.300 kHz should still
produce entirely satisfactory results.
4. Push the [ENT] key momentarily to save your new settings and exit to
normal operation. The "User" mode is now configured for pseudo-USB operation
in the AFSK (Packet) operating mode.
