I have found a design of small loop antenna that would be reasonably easy to put up when portable. I plan to use a FT817 at 5Watts with the loop. I would...
Most loop antennas have EXTREMELY low radiation resistances. Many are less than 1 ohm depending on the size of the loop relative to frequency. With such a...
I just received a NEW AT-1000PRO tuner yesterday - I am finding the same problem on 20 meters. I am tuning a TA-33 that has a SWR about 2 to 1 in the CW band...
I bought a used AT1000Pro and thought I would try in the cw part of the 20m band on both of my antennas. First, my KT34A tuner tunes 1.1:1 at 14.09. Second, my...
... At the risk of perhaps running just a bit OT - I would like to hear more about your 190 ft inv V, particularly as to how it loads/works on frequencies ...
Hi John, You want the AT200PC, there is nothing better. Both PC-ALE and MARS-ALE control its operation so that its in BYPASS during scanning ( which is a MUST...
Wanted: LDG AT-100Pro This is for mobile-portable use. Must be reliable but does not have to be cosmetically perfect. I'd prefer a swap but will consider a...
What does 75 ohm coax do to autotuner performance? I know of several Hams who use RG6 and larger CATV hardline for their feedline. Would using this 75 ohm...
From a performance standpoint, it has no perceivable bearing. The tuner simply finds the best match between the radio and the tuner. Obviously the antenna is...
Hi Doc All my dipoles are fed with RG6 coax and my Z100 takes care of everything with no complaints! 73, Rob G4LMW http://www.G4LMW.co.uk ... From: "kd4e"...
Hi John, You are already using a PC for the ALE controller/modem when using PC-ALE, so what is the difference? You can only use the AT200PRO for single channel...
Great news! That provides some increased flexibility. BTW: I was told that the 50 Ohm "standard" was initially a USA thing and that in other parts of the...
Hi all, I'm using a Z-11 pro tuner and lately it seems to of developed a issue, Once a tuning cycle has finished the atu indicates a swr of below 1-1, but the...
Hi Steve, It could be that the tune has somehow gotten out of alignment. Put the tuner on a dummy load, bypass the tuner, transmit, then adjust the variable...
Great thanks I've just opened the atu up for heart surgery the only vari cap i can see is C11 next to relay K1 towards the rear left as you look at it from the...
I'll add that you might need to turn off the auto mode on the tuner when you do this to make sure the tuner will stay bypassed as you vary the trimmer Cap. ...
Hello to all on the list, I seem to remember a schematic/diagram for a homebrew remote controller for the RT-11 tuner. Am I imagining things, or was this...
Joe, The interface information with a narrative for what each pin does is in the RT-11 manual that is currently on the LDG web site. The earlier manuals did...
With my AT-200Pro, I can see (on the radio interface at the back) that tuning requests are received properly and the AT-200Pro tunes. If the RF input is...
I have a 4y.o. Z100 working OK with 3 older ICOM radios. I am planning to buy a IC7200 and I have been warned by a OM, telling that maybe the IC7200 shares...
Javier, Yes, that is true about the IC-7000, but has no bearing on LDG tuners. We use hi impedance interfaces on all of our tuners (just like the Icom tuners)...
Hello Dwayne, Thanks. My thoughts are to have a box that has the equivalent of the RT-11 Remote built into it. I'd like to have the LEDs and be able to put...
Hi all Wondering if there exists a design (for a cable) to interphase the Elecraft K2-100 with an AT1000Pro to enable the 'one touch tune' feature from the...
Also, has anyone tried using a non-shared (with the AM/FM car radio) power antenna with an LDG autotuner? As the economy struggles crime will increase so an...
