[Elecraft] How to get SWR

The commands are being sent too close together.  Place a minimum 100ms delay between the SWH16 and following DS command.  Do not send any other commands until after second SWH16.

Four macros were setup to allow “manual” delay between commands.  I don’t see a direct way to allow a command-command delay in the command tester.  Reducing the baud rate may help.

Macro 1  FA;DS;
Macro 2  DS;
Macro 3  SWH16;
Macro 4  DS;DS;DS;


The following results were realized:

FA;DS;
FA00007123610;DS at 7±23¶1@€€;SWH16;
DS;
DS@@@@1³>I€€;DS;
DS@@@@1³>I€€;DS;
DS@@@@1³>I€€;SWH16;
FA;DS;
FA00007123610;DS at 7±23¶1@€€;
DS at 7±23¶1@€€;SWH16;
DS;DS;DS;
DS@@@@1³>I€€;DS@@@@1³>I€€;DS@@@@1³>I€€;DS;
DS@@@@1³>I€€;SWH16;

The SWR returned is 1.3-1 as displayed on VFO-A.  The @ in the returned data means there is NO data in that byte position. The returned DS data will require “massaging” to get a proper text string as there is display Icon data mixed in.

A KX2 was used for this test, but KX3 should be the same.
