Aloha Terry!

Ref you note and test results on below:

Thank you for your perseverance and tests.  Wow,  tomorrow I shall
set up such a circuit,  external to both the Omni and 87A.  I read your
solution to mean that the bands point to the Omni,  not the 87A. You
are todays hero!!

Continue to just be amazed at the commradere of the Ten Tec gang.
And,  you know what,  I am sure they will read about all of this
at the factory tomorrow morning.  Be better news than
what I believe is going to be on TV on Monday!!

73,  Jim,  KH7M

>Paul, Jim, and all,
>I made up a cable with a diode in series to connect the 87A "relay" jack
>to a "Y" cable to plug into the "TX OUT" and "TX EN" jacks on the Omni 6 +.
>polarity of the diode has the cathode (band end) connected to the Y.
>This works very FB on BOTH CW QSK and SSB...glad to report. It IS nice not
>having ANY relay chadder even on SSB!
>I DO NOT suggest doing this with any other amplifier unless you know that
>keying line polarity of the amplifier is correct AND that the amp keying
>circuit is of very small current. Actually I would not do it with any
>that uses relays.
>I only suggest this with a Alpha 87A or 89.
