KPA 1500 Remote input 13 broken

[Arthur Nienhouse]

*/I have been using my Icom 7610 for about two years driving my KPA1500
amp via the Remote jack 13 on the rear, setting up the menu in the 7610
and the 1500 all worked just like it is supposed to .
The cable to the ATU remote on the Icom works for the ATU [TUNE]
function its a great combination.

Tap the Icom band button the amp changes bands the ATU finds a match
from memory without any RF transmission its worked 2 years..... now it
does not it just stopped working.  I can not remember any event that
caused it to stop seeing the CI-V data input.

I have confirmed that the Icom CI-V is working correctly so the problem
is with the KPA 1500 remote jack not working.

What should I look for?
Corrupt firmware?
KPA 1500 Utility fault log?

Any help would be greatly appreciated
Regards

What is "Jack 13?"  Do you mean the REMOTE (CI-V) jack on the IC-7610 (a
3.5mm phono connector), or the REM jack on the KPA1500 (RCA), which is only
used for remote power ON, and you probably should not have anything
connected to it.

The most common cause is to plug the Icom CI-V cable into the KPA1500 TUNE
jack (the bottom one) instead of into the XCVR SERIAL jack (the top one).

The KPA1500 REM jack is only used to power on the amp. remotely.  It is
*not* a CI-V connection to the REMOTE jack on the IC-7610.

Incorrect cabling or KPA1500 RADIO menu and BAUD rate not set to match CI-V
Baud Rate in radio.

If you recently updated the IC-7610 firmware, but did not save and restore
your menu settings then everything has been reset back to Icom factory
defaults in the IC-7610.

In the IC-7610 *SET > Connectors -> CI-V* menu:

Set *CI-V USB Port* to *Unlink from [REMOTE]*
Set *CI-V Baud Rate* to *19200*  (do not use *AUTO*.  Do not confuse this
setting with *CI-V USB Baud Rate* which is a completely independent for the
USB cable)
Set *CI-V Output (for ANT)* to *ON*


In KPA1500 Menu:

Set *RADIO TYPE* to *ICOM*
Set *RADIO POLL* to *OFF*
Set *SERIAL SPEED XCVR* to *19200*
