hello,

For those interrested I am starting on a project to automaticaly control the YEASU ATAS-100/120 HF antenna using an ICOM radio like the IC7000.

It will be most likely Arduino based, using CI-V to snif freq, S-Meter and SWR info and the D4 antenna controller to control the radio.

I am looking at multiple variation from very small package with just a couple LED indiccators to 2X16 and 4X40 LCD to TFT Color LCD with touch screen.

for older ICOM radios missing some of the needed CI-V commands (pre IC-706mkIIG), I will had an SWR bridge to adress this.

still a long way to go but look here for updates.

Can you access another repeator using tones? If not then maybe the tone output is too low and needs increased. Service manual stuff. GL

As I said in the original post, offset is correct -600 and CTCSS tone is correct for my local repeater 110.9, have tried various filter widths in case it was something there but no go

Hmm looks like the problem wasnt me after all, the local repeater has been having issues, were all good now

You also have to have the frequency offset correct + - 600 kc for most
What repeater are you trying to access so that we can look up the settings
Perhaps use the Repeater Book app on your phone to check.
You should have a tone set to the correct frequency and the offset as well
If yo push tome and hold it it should let you set the correct frequency, often 100 HZ

I cant seem to see that option anywhere, I would have presumed it would be default but not sure

And ive changed to FM-Tone mode just in case anybody asks

Not that I use repeaters much but decided to try my IC-7000 on the local repeater tonight, cannot seem to access it,? offset is set correctly, ctcss tone is set correctly but I just cant access it, the repeater is close to me so I can access it even with a handheld but nogo with the 7000, no idea whats going on.

Now as for the AT-7000 itself. I ran #8 red/black wire directly from the battery with very heavy duty fuses used typically for mobile sound installations, directly to the radio for maximum power output. All I have to do is push the Tuner/Call button on the IC-7000, and it will immediately seek to find the best/lowest VSWR that it can obtain with the antenna in use. I have found it to work very reliably as long you use good radio installation practices, especially when it comes to really good, tight connections and really solid grounds. Poor ground connections most often (I think) lead to faulty or troublesome mobile operation. Very often, what you may think is a "good" ground, may not be what you think. In vehicles, ground connections are NOT always created equal, so use due diligence when it comes to grounds. Poor power output and/or RF inside your vehicle will let you know right away.

Be sure that you tune your mobile antenna as close to resonance (lowest VSWR) as possible, while it is mounted on the base you will use on the vehicle with an antenna analyzer, (such as a Bird 43 or MFJ 259/269 or a RigXpert analyzer, or equivalent, etc), but NOT using the AT-7000. You need to "start" from a position of knowledge, that is, that the antenna has already been tuned properly to begin with. Tuning it off the vehicle is NOT the same as tuning it ON the vehicle, just the way you are going to use it. I used several different analyzers to just compare and confirm the antenna tuning readings in my vehicle right AT the MALE coax connector that will connect to the AT-7000 FEMALE antenna connector ON the AT-7000 itself. In other words, measure only at the end of the coax that comes from the antenna ONLY, period. (And of course, this "tuning" I've been talking about is actually trimming the length of the stinger (whip) that is adjustable at the top of the hamstick (assuming that is what you plan to use). Then you will know when you use the AT-7000 in the circuit, you should get good results.

Also, be aware that after tuning for best VSWR on the IC-7000 using the Tuner/Call button, you will NOT be able to see VSWR. To display the VSWR
after a tune, select the VSWR indicator scale from the radio’s menu, and transmit a carrier (AM, FM, CW or RTTY). The VSWR will then be displayed on the VSWR scale.

Another great "plus" for using the AT-7000 is the remote-able control head. That is what I am using, and it works great. Also, for a microphone cable extension, I used a FLAT CAT 6 Ethernet cable, one end plugged int the IC-7000 body located under the driver's seat, and the other end right into the underside of the mic which is located in the glove compartment where the remote control head is now mounted.

I know I may have given more information than just that on the AT-7000 tuner, but I've found the more information I can get all of the subject, the happier I am.

If I can answer any other questions, feel free to ask. If I know the answer, I will be happy to share. I hope this has been of some help.

PS I still use my mobile just as described to this day, and it still works great.

I've added some photo's but don't know if this group will allow them or strip them.

I am going to assume you have tried ICOM parts dept,. So if you can remove the part if necessary and look for manufactures part number or something. then search for it. You might get lucky. Good luck.

hi fellow 7000 owners, anyone have a junker 7000 or parts for a 7000 lurking around? I need the connector board. It’s the gold plated male pin set that is mounted on the body of the 7000 and mates with the head unit. I’ll take a damaged one, a good one, parts pieces. Please email me if you have one or even a radio that’s not working or for parts.?

Thanks Richy N2ZD?

The AT7000 works well and is very similar to the IT100. As long as it works everything is OK, but it the CPU fails there are no replacement parts available to repair it.

The AT-7000 works well but it is restricted to 30 watts for all digital modes. de W4WNT.?
