JP1 Remotes

Oops, I misread what John said. It's subdevice 1 and 71 that is in the 1027 setup code.

Yeah, once I was in Tuner mode, when I did those codes 0-7, it selected the various tuner presets (ie, different radio stations). I didn't have it in Tuner until 066, so the 061 and 065 might have been presets too, but I wouldn't have seen it.

The fact that I got a menu item for Left Speaker Delay ...

Ok, I tried CD/0028 and while it's promising, it doesn't actually suceed. After trying the codes listed here, I built a simple spreadsheet and went through all the EFC codes one at a time, to see what I could find. There are clearly codes here to do things on the front panel that I cannot do from ...

Aha! The light bulb begins to go off.

I had wondered for years how it was that all these remotes didn't interfere with each other, assuming that each manufacturer was sending some sort of encoded signal that was unique to it (in a similar fashion to morse-code, really, ie, 1 was this set of pulses ...

The receiver is quite old and I would not be surprised to learn that it has no discrete codes at all. It was, however, the top of the line unit when it was made, so it's conceivable that it does. It came with an LCD Remote that would control multiple Kenwood devices (cd, tape player, even a TV ...

I guess that's the part that puzzles me.

My original remote can NOT do what I want, so I don't quite understand how learning from it will help me.

For inputs it has an Input Up and Input Down button and you have to cycle through them.

I think I now understand that what you are saying is that even ...

You should try the setup code CD/0028. It is NEC1 protocol, device 184, subdevice 0. It is not a combo, so EFC codes should work. Only subdevice 0 is possible for its EFC codes, but maybe the commands you want will turn out to be subdevice 0.
I'll try this, though I'm having trouble understanding ...

There is a spreadsheet in the JP1 Yahoo files | devices | audio section called Kenwood-master-list.zip that Rob Crowe put together that has a matrix of most Kenwood commands. That spreadsheet is just information so you can either download the free Excel "reader" or open it in Open Office.

I did ...

No, there are two codes that seem to give me control over the Kenwood receiver (1027 and 1570). I read on the Remote Central forum that 1570 is a "combo code" that doesn't support any extended codes.

I tried the "set-0-0-0-0" trick for a few numbers, but since I wasn't sure I was doing it right ...

I've spent much of the afternoon reading as much as I can on the JP1 stuff here and at RemoteCentral and I must admit that I'm not really getting it. It occurs to me that I might be barking up the wrong tree and maybe I could ask if I'm going the wrong way before I get too far down that path (to mix ...
