Re: AT-600PRO Autotuner and Yaesu FT-847
Keep in mind that newer LDG tuners now have the radio tune feature disabled.? My AT1000 came in that way, my AT600 still has the feature.? When I spoke to LDG over the phone, he said people were running their radios remotely and burning them up.? I guess they weren't re-tuning once they moved off frequency.

Re: Problem with FT-897 & AT-897+
I'm sorry but had you read & understood the first message in this thread, as well as the repeated, an redundant, conditions in subsequent messages you could have saved yourself a great deal of time and trouble. Over and over again it was stated that there was no fault with any cable(two different factory cables tried). These same cables worked fine with the YT100-FT897-FT859, and AT897-FT859. In addition I repeated that all settings were checked, rechecked, and checked again, and all are in accordance with the instruction manuals(Yes, that's ManualS, I have more than one). These settings must have been correct, and the cables not at fault, or none above would have been true. As such, this all demonstrates that the CAT is working, so I see no purpose in trying to use a PC though the CAT port, IT WORKS! The question was specific to the AT-897+ as seen in the subject line, so your paragraph on the non-plus simply confused the issue. Then finally, I more than once detailed how TWO YT-100 tuners work fine with these TWO FT-897, as well as TWO FT-857. AND that the subject AT-897 worked perfectly with TWO FT-857's, but refused to even be recognized by the same TWO FT-897's. So, given that all the above information has already been posted more than once, how is it that your addition to the thread helped? Again, I'm sorry you worked so hard, but nothing was presented that assisted in this dilemma. I'll delete this thread so as to prevent any further wast of bandwidth. Dennis Starks KB?SFP

Re: Problem with FT-897 & AT-897+
开云体育Thanks for the well-written details, Geert.And, since we're talking FT-897s, the stock Yaesu FNB-78 NiMH 4.5 AH batteries are still available from Gigaparts at $144.95 for the pair. 73, Kent K9ZTV On 2/9/2023 11:03 PM, Geert Jan de

Re: Problem with FT-897 & AT-897+
The AT897 and the AT897plus work in a different way.
The AT897 needs three connections: RF antenna to the 897, the CAT connector (which is only used to get power for the tuner from the radio), and an "OTT" cable that connects via a "Y-ACC" cable to the ACC connector on the radio. When you start a tune cycle, it uses the OTT / Y-ACC cable to trigger the FT897 to generate a carrier. Again, operation of the tuner is via the OTT cable, the CAT cable is only used to get power to the tuner. The AT897plus works differently. It needs only two connectors: RF antenna to the 897 and the CAT connector. There is no OTT / Y-ACC cable or connector, no connection to the ACC plug on the radio. The CAT connection is used to make the tuner talk to the radio, to make it change mode, read out the frequency and trigger the radio to create a carrier. That is all done via communication over the CAT connector, which the non-plus does not do. Important: THE AT897plus NEEDS THE CAT COMMUNICATION TO FUNCTION. There are a number of reasons why the 897plus may not work: the CAT interface may be set to a different baudrate (CAT RATE, option 19). The CAT/LIN/TUN setting may be wrong (option 20), it needs to be set to CAT. The cable may not make full contact because it can't be fully inserted because the connector sleeve is too thick (believe me, I had this problem on my 817 tuner). And perhaps the CAT port is broken on your FT897 radio. Do you have a CAT interface to your PC, to program radio channels? Does it work on your FT897 barefoot? Does the CAT communication still work if connected via the tuner? Note that the default, standard do-it-yourself plug for the CAT connector is too thick and won't properly mate the CAT mini-DIN connector on the FT897. I had to cut part of the sleeve to make that work for a CAT PC interface. And these days, I don't use the standard DIY plug, I bought some Kycon? KMDAX-8P connectors which are a bit of an attitude adjuster if you need to assemble them w/o instruction manual, but which are thinner and don't interfere with the casing of the radio. One of the things the AT897 (non-plus) does is that it just triggers a carrier on the radio. If the radio is set to 100W, then the tuning process is done with 100W. On my FT897, what I have done, is I wired the OTT / ACC plug (the TX REQ signal that the tuner uses), via a 1N4148 diode to the signal that indicates that the 897 is operating from battery. Grounding this pin (the 857 has the same, it is the "brown wire") causes the radio to switch to battery mode, it shows a little battery on the display *and it reduces RF power to 20W*. Because of this, the tuning process now happens on 20W instead of 100W, better for the finals, better for the tuner. If I press the TUNE button on the AT897 (non-plus) tuner, the battery indicator lights up, the radio switches to 20W and does the tune thing. After tune, the signal is removed and the radio switches back (potentially to 100W). This trick is not required on the AT897plus tuner because one of the things it does, via the CAT connector, is reduce the RF power; that is something the AT897 (non-plus) cannot do because it doesn't use the CAT port to talk. I'd be interested in your results. 73, Geert Jan PE1HZG |

Re: Problem with FT-897 & AT-897+
开云体育From the AT-897 Plus manual: "The 8-pin CAT interface connector is Kycon Connector part number KMDAX-8P, available from http://www.mouser.com/ as Mouser part number 806-KMDAX-8P. ? Pinning for this cable is one-to-one, straight through; all 8 signals are used."

Re: Problem with FT-897 & AT-897+
I used two different cables, and as I think I noted, the YT-100 works perfectly with the 897, and the AT-897 works perfectly with the FT-857. The AT-397 just will not work with the FT-897. Cables are not an issue and all settings are? what the manual says they should be. Dennis Starks Military-Radio-Guy KB?SFP

Re: Problem with FT-897 & AT-897+
One issue with LDG tuners and Yaesu rigs is on some of the tuners the control cable switches the tip and inter ring connections.? They cross at the connector.? tip of one goes to inter ring of the other and the inter ring at the rig goes to the tip at the tuner.
