The auto tuner is going back to its last remembered band settings. ? Normal function as if one had to manually tune to a band using a legacy tuner., ? Joseph D. Yuna

No tuner is going to instantly tune to your new frequency, and why would you immediately start talking until your radio and tuner were not done configuring for the new band? ? ? ? Joseph D. Yuna

Re: Why do I have to continually retune my radio?
Hi J.D.,
I use both a G5RV and a multiband dipole.,
I suspect it has to do with the automatic vs. semi-automatic use of the tuner.
I appreciate?your guidance!

I have seen a lot of problems with end fed antennas with matching baluns at the feed end that have the ferrite cores bad from overheating. This usually happens after operating for a while, and usually on a data mode and not as often on voice SSB.
As a result I don't use the multiband End Fed Half Wave antennas, but rather a long wire with the tuner located remotely at the antenna feed point in a protective box. This way the coax feed has a low SWR and low loss and the match to the long wire is made without additional matching networks.
All of that said some people have had good results with the EFHW antennas (and some don't). Most of those that have had problems have radios that will aggressively reduce power if the SWR goes too high, many of the IC-7100 radios. The love their antennas, however and some have sold their IC-7100s thinking that the radio was bad, no matter the diagnosis.?
Anyway check the SWR of the antenna before the tuner if possible as there may be something changing the tuning parameters that the tuner may be chasing.

Re: at600proii ft1000mp mark v and tube amp
I'm not familiar with the Mark V but with my ft710 I have a crossover 1/8 inch cable from the remote plug on the radio and the AT1000Pro2. When I do a short press on the tune button on the tuner it initiates a tune cycle with a carrier from the rig.? I would think it would be the same or similar on the Mark V.??

Subject: Re: [ldgelectronics] Serial Data issue on PIC METERTX METERRX? Stop ? Program seems old and uninstall able on windows as is. ? W4JDY / EM79xr / ITU 8 / CQ 5 ? ? For years I have been using a software program called LDG Tuner Control, to interface my AT-1000ProII Autotuner () with my PC by using the meter jack at the back of the tuner, but I lost the capability recently either due to a software or hardware failure. At first I changed my USB to serial interface used to control the tuner. Then verified the computer sends the commands to the tuner using a serial sniffer, but noticed the tuner does not respond. The tuner works just fine otherwise, it just does not give a power readout and the ability to remote control it. Looking at the schematic, the METERTX and METERRX lines used for communication between the PC and the tuner, go to the PIC? directly (photo attached). Is it possible that by chance, those pins got fried, without the rest of the chip being affected? If so is it possible to burn a new PIC to test it out? My label says ver1.7? Have not seen any hex dump available in the file section. Any help is appreciated. Thank you.

at600proii ft1000mp mark v and tube amp
Hello
?I just bought the AT600proii to make using my vintage amp a little easier. I have figured out how to connect it to my ft1200 and use the tune button? but can't find anything about the Mark V field. I think it would plug into REMOTE Jack (2) but want to be sure.
Thanks john NM2R

Re: The smoke got out....
Based on the amazing customer service I've received from LDG, they'd probably happily send you the replacement caps. But it's probably faster to simply source them yourself.
