[Fourlanders] FT8/MSK144 Settings with an Icom 7300

[John Kludt]

All,

Everyone seems to have different idea as to the proper mixture of ALC and
drive power when using the IC-7300.  The attached document is from Icom and
describes the correct setup for the IC-7300 and other Icom radios.  The key
takeaways are:

   1. No ALC
   2. Power on the radio at 100%
   3. Adjust output power with the power slider on the right in WSJT-X

As I think this through, using this method will require some care when
switching from a digital mode to SSB/CW if a amplifier is being used.  When
in a digital mode the drive to the amplifier is set using the using the
power slider on WSJT-X.  No problem.  But if I now switch to SSB the PA
will see the full 100 watts of drive. Probably not a good thing!  So the
process to switch from digital to SSB now becomes;

   1. Cut the drive power back to a safe level (20-30 watts with the Beko
   for example)
   2. Switch to SSB on the 7300
   3. Check PA power out and adjust if needed
   4. Have a nice day

Note in their discussion the relationship between ALC and power out of the
radio.
