LDG AT-600ProII Autotuner M-600 Meter Setup With Short Review

K0PIR

I'm an Amateur Radio enthusiast. I love the hobby and experimenting with radios, antennas and software. On my YouTube channel I upload videos on the Icom 7300 and Icom 7610 along with Ham radio software programs. I hope to inspire people to try new things in Amateur Radio.

I’m a new 7300 owner. Why would this rig, which comes with a tuner, require an additional tuner? I’m running it barefoot into an end fed antenna and so far the internal tuner seems to work on all the bands.

Thanks for all the videos.
Just was looking for a tuner for the 7300 and I guess I buy the 200 version.
The IC-7300 has smaller tuning capacity then my old TS870, but what can you want for a few €€€.
Still struggeling with FLdigi, but for the rest all is working fast with the 7300, MixW and WXJT.
Menu 7300 is very good, you can do a lot without any manual at all.

Hi Rich,
I got all excited when I read your review of the LDG AT-600 Pro II and the IC-PAC cable. I run an AL-600 linear amp so I also use a LDG AT-600. Unfortunately I have the older AT-600 Pro which does NOT have the additional connectors. I love the autotuner, but hate not being able to tune it before transmitting after switching bands (my Yaesu FT-450D had a neat little button that would send a silent 10W carrier signal to tune). For anyone else with an older autotuner there is a product called a TuneRite . It plugs into the tuner “port” on the back of the IC7300 (or other Icom) and fools the transceiver into thinking there’s a Icom autotuner attached. Thus when one pushes the tune button the IC7300 sends the 10W carrier rather than trigger the internal tuner. It ran about $25 from a German site. Just an FYI.

I just purchased an Icom IC-7300 and the LDG AT 100 ProII so watching your video was helpful. One thing I’m running into is both the internal and external tuners are trying to work at the same time. You mentioned in the video that there wasn’t any changes that needed to be made in the radio’s settings so how do you deactivate the internal tuner or should you?

Thanks,

I purchased a AT 600Pro II after seeing your video and ordered the cable that connects to the 7300. On my own, I would have not known about this cable so Thanks.

Rich, I’m using a 7300 and 7610 with an LDG 600 watt tuner, Icom cable, and Ameritron solid state amp. Regardless of how or where I initiate a tune cycle (at tuner or radio) both tuners seem to want to operate. Is there a way to disable the 7300 tuner so it will not attempt to tune the amp input circuit needlessly? On my previous IC-756 ProIII you could use ANT 2 and the internal tuner was not in the RF path. Any similar work-around on the 7300?

Thanks. This is exactly the info I was looking for as the manuals can be a bit vague regarding a specific setup. They’ve discontinued the meter so I will start the search. 73 N5VL

I am interested in using the LDG AT-600ProII in a go box. The company I’m working with to build the go box has noted that LDG is pretty bad at exact size specs.

Would you be willing to measure your AT-600ProII, please? Width and height. I’m shooting to install 2 of them side-by-side. Thanks in advance.

I have a 7610 connected to the AT-600Pro2 with the interface cable. I am running a ALS-600. When I place the ALS into standby and with the AT-600 set to “semi-auto” mode I push the tune button on the AT-600 for >.5<2.5 sec. According to the manual the radio is supposed to go into reduced power, switch to CW mode and begin transmitting while the tuning cycle is in progress. However, this transition is not taking place. When tuning I get the quick flash of the upper LED’s on the AT-600 indicating no RF leaving me with no option but to manually place the radio into AM mode and manually key the mike to initiate a tune.

Any idea what could be going on? I spoke to LDG and they are sending me another interface cable but I had already ordered a replacement from Gigaparts and plugged it in with no change.

Any suggestions would be appreciated’

So are you saying that you don’t have to key the mike to initiate a tune on the radio? My tuner will tune automatically in the full auto or semi automatic mode when keying the mike. It just won’t tune in either case unless I key the mike.

I put the tuner into simi-auto mode (function C-dn). That prevents automatic tuning when using the amp. Initially I still put the amp on standby and initiate a tune cycle manually. The issue I have is that I have to key the mike to tune. The manual tune button on the tuner isn’t doing a tune cycle without keying the mike. The tuner does turn on when I turn the transceiver on though so the interface cable is talking.

Antenna is connected to antenna 1 port on 7610. I tried forcing a full tune by holding the ATU button down for more than 2.5 seconds. Won’t work unless I key the mike.
