Re: [oo ] Icom IC-706MK2 IC-706MK2G vs LDG AT-100ProII Autotuner issue

",sometimes it wipes the operating frequency completely off the radio display"
?
That statement makes me wonder if you don't have a current draw/PS issue. The tuner has no way of messing with the frequency display. That sounds like a power glitch.?

Re: [oo ] Icom IC-706MK2 IC-706MK2G vs LDG AT-100ProII Autotuner issue
Al no I’ve not changed antenna config,sometimes it wipes the operating frequency completely off the radio display ,and tuner switches to bypass mode ,today I’ll give the Tuner Manual a good perusal and Radio Manual ,thanks Al 73 Dave 2E0DTB ,50 to 70 mph wind gusts today?
My take would be the tuner can’t tune the load.? Did you accidentally change the antenna selector on the tuner? What happens if you set the 7000 on CW at low power, key it, and hit the tune button on the tuner? ? All else failing, reset the tuner. ? Al K5TAN ? ? Guys I hope you don’t mind me hopping on this thread,I have an Icom 7000, i too have have an LDG AT-100Proll Autotuner ,I’m using the supplied interface cable from radio to LDG Tuner,all was fine till recently ,when I iniate a tune cycle ,it now takes 15-20 seconds to complete tune cycle ,and tuner goes into ByPass mode ,I can clear ByPasss mode by pressing C Up button ,but that don’t seem right ,any help I would really ?appreciate ,as I say sorrry if ive highjacked this subject ,73 2E0DTB,look forward too replies ,Dave

Re: A wonderful gift, but no manuals.
Hi Mike? If the power M1000 doesn't?work with the tuner you can get the working tuner firmware pic chip free from LDG, to make the data port work again, Dave 2E0DMB?
Hi Dave, and thank you.
I seem to recall in some instances there are different versions of tuner and manual.? I also seem to remember some discussion about the M-1000 meter not working on some versions.? I was going to wait until I had it in my hands, and know what I really have.

Re: Icom IC-706MK2 IC-706MK2G vs LDG AT-100ProII Autotuner issue
Thanks for the proposal!

I had similar thought, since the LDG has 1MOhm pull-up resistor before the comparator, but the simple dummy-tuning schematics (like I attached in my previous reply) operate usually with 10-47kOhm.

I will try it tomorrow evening.

Have a nice day,

Re: Icom IC-706MK2 IC-706MK2G vs LDG AT-100ProII Autotuner issue
My second post, with the attachment is not showing up.? You need to add a 43K resistor between pins 2 and 3 of the molex connector for the G-model.? It can stay for the non-G model also.? The non-G model already supplies the resistor, the G model does not. ? Al ? ?

However, if I connect the tuner to the 706MK2G with the same cable, same conditions, the radio does not detect the tuner at all. This means that the red LED does not even flash when I press the Tuner/Call button on the radio. I did a factory reset on the MK2G, but it didn't help.
I have tested the tune interface of 706MK2G with the well-known dummy tuning circuits from the Internet to activate the tune service of the Icom, everything looks perfect.? Do you have any idea, why my 706MK2G is not compatible with the AT100ProII??

Re: Icom IC-706MK2 IC-706MK2G vs LDG AT-100ProII Autotuner issue
The only communication from the radio to the tuner is via the tip of the radio plug on the tuner. When it is pulled low it signals the pic controller on the tuner to initiate a tune cycle. The ring terminal on the same plug is to signal the radio to initiate a carrier for a tune cycle. It is initiated by a signal from the pic to transistor Q1 to pull this line low. There is no serial communications at all. The complete schematic is in the files section of this group.
