[Elecraft] TX EQ setting

[Peter Connors]

I have identified an easy way to switch between various TX EQ settings 
using N1MM or Logger32 thanks to information kindly supplied by Bill 
Coleman N2BC, author of K3_EZ.

The method involves using the macro functions in each program to set 
compression and TX EQ bands. For example, flat with no compression in 
Logger32 would be
$command cp000;mn008;swt53;mn255;$
which zeroes compression, clears the existing EQ and tidily terminates.

For my DX/Contest setting I use (the space after 'command' may appear as 
a line feed):
$command 
cp025;mn008;swt53;swt11;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;swt12;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;dn;swt13;dn;dn;dn;dn;dn;dn;dn;dn;dn;swt24;dn;dn;dn;dn;mn255;$
which sets CMP to 25, clears the existing EQ and then sets it to -16, 
-16, -9, -4 in the first four bands and then exits gracefully.

The N1MM macros need starting with {CAT1ASC instead of $command, then 
terminating with } instead of $.
Other EQ settings can be easily set by examining the K3 Programmers 
Reference; a macro that needs very many commands may exceed the maximum 
length which is 255 in N1MM, unknown for Logger32.
Although the Programmers Reference suggests that successive SWTxxx 
commands may need 100msec delay to 'set', these macros work with the COM 
port at 38400 without any apparent need for command pacing.

PS I have just read Wayne's mail about keeping EQ settings within ±6dB 
so I am about to change the macros after writing this. Perhaps Wayne 
will reduce the limits in future firmware?
