We have more than one tuner here. A User group And not a tech support site. In any case, just try it or be prepared to lift the internal battery as with all embedded systems. W4JDY / EM79xr / ITU 8 /

Right Mike... There is no backup battery in the LDG tuners I have, they use EPROM for freq recall.?? I have an AT-600Pro on my op desk for my vertical wire (my only antenna presently as I recently

Hi Ed, I don't believe there is a memory battery in the AT-200 Pro II, or any other LDG tuner, so there is no battery to "lift". I assume that means take the battery out. From what I've read memories

If the arrester has no dc path to ground, at the entry point to the building is fine. Some have an inductor to ground for static bleed. This will also send the 12VDC to ground as well. Check it? with

Joe, I've been a ham since 1977 and an elect tech since 1964... I just don't understand you. 73, Ed - ad7gr

Exactly. On my vertical, I place a 2.2M resistor with a NE-2 bulb to bleed off the atmospheric charges that Aare about 200V per meter. Joseph D. Yuna Joseph D. Yuna (LCDR USN/ret.) W4JDY / EM79xr /

I put mine right at the antenna patch panel where it enters my windows as the grounding is outside there anyhow. Always ground at the nearest point where you need suppression. Joseph D. Yuna Joseph D.

Unless you model cannot be reset from UNC-ANT-TUNE while applying DC power to do a factory reset, then one has to open the case if you are a tech or savvy skilled Ham, and disconnect the battery

Between the antenna and your RT100. Fun fact, old time hams used spark plugs for lightning arrestors. Another fun fact, if your rig is a Yaesu which has ATAS function, you don't need the bias-T box,

Where should the lightening arrestor be placed? Can/should it be placed on the biased feedline where the cable enters the house?? Should it be placed between the antenna and the RT100 to protect the

" lift the battery"?? Sorry, I'm not familiar with this term.?? Do you mean to remove power from the tuner? Ed - ad7gr

It is User selected as to the SWR level that that function triggers. FUNCTION CDN sets the tuner to autotune. Sent: Sunday, January 12, 2025 4:13 PM To: [email protected] Subject: Re:

As with most if not all ldg tuners when rf power is applied and swr is more than 1.5:1 the tuner will try to tune automatically? Ron n9ee

LOL. I’ve borrowed an AT-200Pro (not a ProII) and yes, it does have a factory reset!
