Hello,

You will not need the 318 with the TS-590 as it has sufficient delay to 
prevent hot switching during CW.  Now if you desire to run full break in
on the TS-590, it may cause issues.  In that case, the Omni VII is the 
better choice for full break in CW with the TX IN/OUT configuration.

I run my Orion and Titan amp this way (TX IN/OUT) and run my K3/Centurion 
using the key in and the ptt/vox setting.  I don't run full break in
on either set up so I have not had any issues with the delay being too 
short.  It looks like a nice interface for those who seek something such
a device.

Oh Yeah....
Like I am equipped or sufficiently informed to pull all that off !

I am still kinda new too some of this ham stuff.   Not the sharpest, but
not the dullest knife in the drawer, I don't understand it all ... yet...

so:

--  Scene 1 --

My Omni VII works seamlessly with my Centurion amp - using the TX EN and
TX OUT loop, and the QSK setting on the amp front panel.  No problem...
I trust TenTec to have set this up and it works perfectly.  I presume
the 318 is not intended to solve any problem under t his scenario,
because there is no problem  under this scenario.

-- Scene 2 --

I set my TS-590s  to have a 10 ms delay.  It keys the Centurion and I
use the Key IN jack on the back of the amp, and use the PTT/VOX setting
on the amp front panel switch.   This appears to work fine.   I key the
mic... the amp comes on ... and I talk.  No apparent problems.

Questions:

A)   So...  what would the 318 do for me under Scene 2 ?
Is it "needed"  or just that it would work with the rig?

B)   Would the answer be different if I was operating CW versus SSB?

C)   Would the answer be different if I was operating CW in QSK
mode versus non-QSK mode?

D)   The TS-590s has two delays,   10ms and 25 ms.
The Model 318 has a 100ms or longer delay.
Do I want or need this longer delay?

E)   Are these delays the same?   Is one a wait-to-transmit delay,
and the other a wait-to-receive delay?

I am so sorry to have to ask such basic questions, but the user manuals
do not explain this sort of thing very well.  No one likes to appear
ignorant, but I concede this is beyond my at this point  (He said, as he
reached for his Teflon, flame-retardant suit.)       ;-)

Thanks in advance.

Sheesh... and I had to pick a hobby where you learn stuff all the time !
    ;-)
