Has there been any thought or discussion of remote locating the control board away from the actual tuner board?
There is a 16 conductor ribbon cable of a few inches long that connects the control board to the tuner main board.

16 conductors of external antenna to strip RF away from, but other than that, would this not lend itself well to trunk mounted tuner and dash mounted control and monitoring?

Also thoughts of a weather proof enclosure, a Balun, and balanced dipole feed point tuner with control in shack?

Or are these just the ramblings of a person with not enough to do?

Thoughts?

I've owned two Pro1000II tuners and one Z-100A tuner. I purchased the Pro1000 because my Z-100A is near perfection but I wanted more power for digital and also an upgrade path, if I ever receive my Mercury IIIS. (I just wish the Z-100A would not sometimes take a several seconds to tune, so I could use it with the fragile FETs in my PreppComm MMX QRP CW transciever/decoder/encoder SDR--I had to replace the surface mount FETs once so I stopped using my LDG tuners with the MMX :( ).

My first Pro1000 had the behavior you described and several other problems storing and recalling previously stored frequencies as well as problems achieving a sub 1.7:1 (or even 2.0) SWR, unless I manually adjusted and stored (which it would often forget in a fairly short time). Manually adjusting L and C on the old one would sometimes only work in one direction; I'd go too far with button clicks and could not go back "the other way" with an opposite button click. I would then need to do a full forced tune (long press) and start over manually, having counted button presses the first time to not overshoot.

Sometimes my new 1000 still fails to find a sub-2.0 tune. (I don't really care much if it doesn't achieve the 1.7 setting, because I just want to keep my transmitter from rolling back the output, given that, AFAIK, standing wave coax losses between antenna and transmitter are invariant of the match achieved)

Have you been able to fix those issues you were getting ?

Thanks for your reply

Side question, how do you read the state of the relays?? Is this in the manual?

Sorry I missed that question, when you manually tune the C or L manually, you can see every of the 7 bank of relays for each C and L populating with the LEDs. When they are all off, no LED show up and all LED will flash to tell you they are all turn off. When LED are all lit, all the relays are engaged.

I purchased an FT-710 on two days ago on Nov 26. I am trying to find a cable to connect either my Z-100Plus or Z-11ProII. The information that I find online is that the Y-ACC-2 cable works with the FT-710. Because of the delivery delay of the cable from LDG, I ordered a cable on eBay. The cable works with my FTdx-10. However, my FT-710 does not have a 10-pin connector on the back of the radio. It is an 8-pin connector. The manual that came with the radio states that it is an 8-pin connector (see attached photo). I am unable to find a reference to any LDG cables with 8-pin connectors. Can anyone help?


Thanks,

Hello everyone,

I've tried to find information on how to recalibrate and retune the internal analog adjustments for power and SWR reading inside the AT-1000PROII but I did not find any procedure on how to do this.

Is there a service manual beside the schematic that would provide information on how to proceed to recalibrate those adjustments ?

Thank you !

I think he is asking for one, not offering one.

Why won't my LDG 1000ProII auto tune in the lower 80m band?

Although my 1000ProII often fails to tune as accurately as my Z100-A, it usually brings the SWR down below 2:1 without the need to manually push the L or C buttons (which can often further reduce the SWR by a good margin). However, I just ran into a situation where my 1000ProII completely fails to obtain an acceptable sub-2:1 tune (even when the 1.7:1 max option is set). After recently changing the connectivity to my 80m OCFD antenna, I am forcing "full" tunes ("long" button press) to re-populate the tuner memory with valid settings, but the SWR in low 80m is usually now worse than the bypass SWR!

Strangely, my feed line SWR in low 80m is completely reasonable for auto tuning (under 2.88:1) and significantly lower than realized in the higher portions of the 80m band, which DO auto tune successfully. (See the attached SWR plot taken at the end of the coax in my shack.)

This problem popped-up after I took action to correct coax shield common mode current problems from my N9SAB OCFD, which DJ0IP says is problematic of all 80m OCFD antennas, so I wound and installed an exact copy of the Guanella choke section used in DJ0IP's highly rated B10 hybrid balun from his "Battle of the Baluns" test:



After attaching my tiny new choke onto the SO-239 connector of my antenna's 4:1 Ruthroff balun, SWR sweeps across all bands became invariant with coax feed length and position (excess coax placed either on the roof or on the ground, etc.). Although the antenna also now functions better, as revealed in my regularly scheduled nets and QSOs, the SWR plots are also now completely different and all bands need to be re-tuned--preferably auto-tuned.

Unfortunately, my 1000ProII now completely fails to auto-tune in my favorite and most often used digital frequencies between 3.5 and 4.0 MHz. Manual L and C button adjustments do not help. I eventually discovered the High/Low Relay manual adjustment in the "Advanced" section of the manual, which enabled me to successfully complete L and C push button adjustments and save them to memory for future auto-tuning (fingers crossed--the tuner really needs an "always use memory settings" switch feature, because it will sometimes do an auto-tune that ends up being inferior to a stored settings tune).

My IC-7100 significantly reduces power to well below 100W after a 1000ProII auto tune. I upgraded to the 1000ProII from my LDG Z100-A to eliminate the Z100-A 30W digital mode limitation and help with my topographically challenging Idaho QTH. My entire system is currently 100W max, but maybe there will be a Mercury IIIS amp and other upgrades in my future too, so I went for the LDG flagship model.

Hopefully this post may prove to be useful to others and perhaps some group members will reply with their ideas or answers too.

73 and thanks!

Purchased an FT 891 with a Z 100 Plus (used) but no operators manual with the Z 100 Plus. YouTube videos are great, but would like to download the manual. The LDG website refey me here. Any advice??

Does anyone have the wiring connections for the 4 pin Icom connector and the wiring connections for the 1/8" plug that plugs into the LDG PROII tuner please.
